How a Lithium-ion Battery Assembly Line Works?

As the demand for electric vehicles (EVs) and energy storage solutions surges, the efficiency of lithium-ion battery assembly lines plays a crucial role in determining the success of battery manufacturers. A well-optimized assembly line ensures high precision, consistency, and cost-effectiveness. But how does the process work? Let’s dive into the key stages of a lithium-ion battery assembly line.

Cell Grading: The Foundation of Excellence

Cell grading is a crucial first step in the process when each battery cell is carefully examined to ascertain its performance parameters. To produce a thorough "report card" for every cell, capacity, and internal resistance are carefully examined. This methodical procedure guarantees uniformity and groups cells according to their performance attributes, establishing the groundwork for the best possible utilization of a battery pack.

Cell Sorting: Precision in Pairing

After grading, cells are sorted based on their specifications, optimizing the performance of the final battery pack. By ensuring that the batteries in a pack are precisely matched, this precision matching maximizes performance and prolongs battery life. To fully utilize each cell's potential within the battery pack's overall power, this phase must be carefully planned.

OCV Testing Machines

Open Circuit Voltage (OCV) testing machines measure the voltage of cells to ensure they meet the required standards before assembly.

CCD Polarity Tester

This equipment is used for precise alignment and assembly of battery components, enhancing the overall efficiency of the production process.

BMS Testing: The Guardian of Performance

At the heart of the battery pack lies the Battery Management System (BMS), serving as its vigilant guardian. Before integration, the BMS undergoes rigorous testing to validate its functionality and its ability to effectively communicate with the individual cells. This crucial step ensures that the BMS is equipped to monitor and regulate the health and performance of the battery pack with unwavering precision.

Cell Welding: Where Precision Meets Connectivity

As the testing cells await their transformation into a unified force, the delicate process of cell welding takes center stage. Automated robotic arms execute this task with precision, forging strong and reliable electrical connections between the cells. The seamless integration achieved through cell welding forms the foundational framework for the battery pack, ensuring its resilience and efficiency.

Battery Pack Testing or Aging: Trials of Endurance

The culmination of the assembly line journey leads to the final stage – rigorous testing of the complete battery pack. Depending on its intended application, this phase may encompass charging/discharging cycles to simulate real-world usage or accelerated aging tests to evaluate long-term performance and safety. Through these trials of endurance, the battery pack's resilience and reliability are put to the test, ensuring its readiness for the demands of modern life.

Battery Comprehensive Testing

Finally, comprehensive testing machines assess the battery packs' overall functionality, safety, and longevity before they are ready for deployment. The integration of these advanced machines not only streamlines the production process but also ensures that you deliver high-quality, reliable battery packs that power the future of transportation.

Conclusion: Precision, Innovation, and Reliability

From the meticulous grading of individual cells to the comprehensive testing of the assembled battery pack, the cell-to-battery assembly line embodies a fusion of precision, innovation, and reliability. Each step in this intricate process plays a pivotal role in shaping the quality, safety, and performance of the batteries that power our modern world. Behind every seamless charge and every enduring power source lies a journey of expertise and dedication, culminating in the creation of batteries that stand as pillars of energy in our technologically driven lives.

The Night Before the Tribute In Light

September 10, 2003

I.

One month ago today, this long-forgotten photo suddenly popped up in the photo app on my laptop. I took this photo with my Sanyo clamshell phone on September 10, 2003, 21 years ago tonight, from Hudson River Park in Manhattan.

Don't ask me how it survived all these years or where it's been stored all this time or how in the world it could have found its way to me from the long-dead storage servers of a long-defunct cell phone carrier. We're in the penumbra of The Anniversary, and time is out of joint.

I had been back in New York for about a month (after getting violently run out of the place I was staying by a fellow who is now one of my closest friends), homeless and living in that roach-infested HIV crack-house shelter at 96th and Broadway that I describe in "The One Decent Thing I Ever Did" (it’s archived on this blog), and you can imagine my state of head and spirit at this moment, the night before the 2nd anniversary of the terror attacks on the World Trade Center that drove me from my home in Lower Manhattan, four blocks east of the site.

I was sitting on a bench in Hudson River Park on the West Side of Manhattan, somewhere near Houston Street, maybe ten or fifteen blocks north of World Trade. I hadn't noticed these beams of light as I walked, and I think they might have just been activated while I was sitting there. As I recall, it was a full moon in Virgo, and I was positioned just right to snap this shot. I had *no* idea what this was all about, as I recall, but I thought the image was so striking and affecting that I wanted to capture it.

As it turns out, this was the tech run-through for the first September 11th installation of the “Tribute In Light”. Here’s Google’s AI summary of this remarkable memorial:

So there I was, just two years after the blast, stunned by this sudden, mysterious apparition rising from just south of what was still a giant, messy hole in the ground. I was still not fully myself at that time and would not regain my full memory or sense of who I was until the following January (therein lies a tale!), and as I recall I was just numbly stunned, not knowing what to make of it.

As I write, I’m getting the physical sense memory of that moment: the dog in me (my medulla oblongata speaking) feels his hackles rise, it’s not what I expect to see filling the hole in the sky, is it another attack? Do I bark at it, sound an alarm, run towards it, away from it, why is there light there, is this some unholy ruse, another trick being played on me from that big smoky hole where nothing but poison has spilled out for the longest time?

My phone rang. It was a fellow that I had met and hung out with in San Francisco while I was stranded there, and I was stunned to hear from him, especially at that moment. “Hi Dave… well, right now I’m on the riverfront looking at the damnedest thing… [I just wanted to make sure you were ok] hey, thanks for checking in… yeah, take care bud.” I closed the phone and started walking south along the riverfront, toward the light beams.

When I got there, I saw the massive banks of klieg lights assembled in their arrays, a strange and unfamiliar (unwelcome) echo of the shapes and the placement and the footprints of the place I loved so well.

The faces of the artists who surrounded the lights were intense, focused, sober. I still didn’t quite know what was going on, but there was profound reverence in the air, on those faces, at that place, as the beams of pure white light soared upwards, past the point of naked-eye discernment, unending, likely petering out tens of thousands of feet off that spoiled piece of ground, perhaps piercing the ionosphere, did they get clearance from the Federal Aviation Administration for this? Are pilots being disoriented by these columns at 45,000 feet? Do they touch the feet of God?

II.

And I kept walking south, my back to the light,

Down to the oldest part of the civilized island,

Past the Battery, the bronze bull, the buttonwood tree,

The Port of New York dead ahead,

The Staten Island Ferry terminal, ramshackle, ancient,

Entry restricted by terror tape and armed sentinels

No two uniforms alike, a panoply of enforcement,

Heavy weapons at the ready, so jarring in my neighborhood,

And the working dogs with the keen snouts, the trained muzzles,

Jumping up to paw at the brown bag in the soldier’s hand

Is that peanut butter? Apple? Hunk of cheese?

Let’s play! You’ve been so serious, so worried,

You smell sad and scared, are you lost? Let’s play!

Even Cerberus needs break time, belly rubs, treats!

For the first time in weeks, I smile to myself

As I round past the ferry, those strange lights at my back.

Hope I can sneak past the turnstile downstairs,

I won’t have to hike back up three hundred blocks

To that awful low place. Did you know roaches bite?

They shit on you too. Try to sleep, fully dressed,

Watch cap pulled low on my head, long sleeved shirt

Buttoned up to the collar, heavy pants tucked in boots,

Gloves on my hands, one more night without food

Half-bag of speed takes my mind off the pain

Sleep comes in fits if at all. – On the train

Dreading the stop: ninety-sixth street and Broadway.

Tomorrow, this city will jack itself off

In performative weeping and gnashing and cursing

Oh, how we loved them! I snort in derision,

You didn’t lose nothin', you pieces of shit!

Let the dead bury the dead. Beams of light

Don’t feed this refugee reeking of ashes -

What, do I smell bad? So sorry to stink up

The place where you’ve laid out the feast for your friends

Who still have their jobs, their high homes in the towers

Behind the glass doors where your larders are stocked

With the food that you bought with your government money

That flooded your midtown Manhattan apartment

With all the new clothes, electronics, the sausages

Fresh from Enrico’s, Zabar’s, D’agostino’s,

Bought with the Victim’s Fund money you stole

When you filed your claim. “OMG, it was awful!

“I couldn’t get up to the fifty-fourth floor,

“I had to find shelter on Upper Park Avenue.

“Power was out. I was homeless that night!

“So glad that my friend who was shopping in Gramercy

“Gave me the number to call for my claim

“September 11th was horrid! I told them

“I couldn’t go home for two nights! Oh, thank God

“The claim got approved with a wink and a nod

“And no one’s the wiser – I’ve never been south

“Of the Plaza Hotel! That all happened on Wall Street,

“Who goes down there? Jesus Christ, are you kidding?

“That’s four miles away! Christopher, are you coming

“Or what? Reservations at Nobu won’t wait

“For you or for me, so quit primping!”

The pain

In my stomach, relentless. My gorge won’t stop heaving.

Am I gonna make it? Damn, *ouch!* What the fuck…

The tooth that I hoped would hold out just gave way,

Fuck me. Another huge hole in my grille.

When I made six figures and lived in a high-rise,

Fuck buddies laughing on Saturday night,

Nobody told me that one hundred minutes

And two hijacked jet planes would make such a difference.

No one will laugh with me now – my best friends

Are yelling and angry, how dare I show up

Sweaty and toothless, a walking reminder

Of September tenth. No, I’m not gonna feed you.

III.

Now, twenty years later, they’ve retooled their memory:

“Animal! Damn, dog! We’ve missed you, you know,

“Wow, you’re alive! You look fabulous! Listen,

“I never gave up on you. Give a call

“When you come to the City. I want you to meet

“My beautiful husband – he remembers you too!”

IV.

Twin beams of light where the Towers were anchored,

Okay, not exactly precisely those spots,

But who’s gonna criticize? Look and recall

How majestic they were. Yeah, the new One World Trade

Is cool, I suppose – no one mentions the absence

Of Two World Trade Center. Insurance, you know.

Not enough money or civic ambition,

And Bloomberg discouraged it. Why add a target?

“Don’t you think sixty or seventy stories

“Are more than enough? Hell, let’s just get it done.

“The sooner we finish construction, the better.”

V.

*There will never be lumens of adequate volume

Sufficient to seal that hole in the sky,

But the hole in my heart I will finish, I tell you.

Walk with me as I go forward. Tomorrow

I’m back in the studio. Tonight, we can play!

You smell like apples and – damn, is that chocolate?

(our light beams shine upward forever)

"Good boy!"

S.A.M by "Bill" (1978). "S.A.M (Short for "Sentient, Autonomous Mechanism" or "Smart Ass Machine", depending on his (and my) mood on a given day, was one of my first real robot projects, started in 1978 when I was around 15. His "brain" was a single-board Z-80 computer (the big square object in the middle of his "back" in this picture), with many bits of TTL I/O, a couple of serial ports, a bunch of counter-timers, and several D/A & A/D channels. The base was taken from the book "How to Build a Computer Controlled Robot" by Todd Loofbourrow - I had built the robot in the book, and had used my KIM-1 to control it. Later, I decided that just a little platform was kind of boring, so I added the upper torso shown here. The torso (mounted on a "lazy-susan" turntable bearing) is rotated by a heavy-duty gear motor driving a chain and sprocket assembly from a bicycle. The base is powered by two of the (apparently no longer available, which is sad) all-metal rubber-tired "motorized wheel" assemblies that Herbach & Rademan used to sell, with a large rubber-tired caster in front. The head platform (mounted on a small "lazy-susan" bearing) was originally rotated by a surplus gearbox from a Mattel "Big Trak" with some rubber-tired wheels mounted on the output shafts. This arrangement was later replaced by a small gear-head motor driving a large gear mounted to the center of the turntable. The device in the head with the tubes sticking out the front is a directional light tracking device. Each tube has a CDS photocell at the bottom, and is painted flat black inside. A comparator circuit tells the computer which direction the brightest light is coming from. This device could also tilt up and down with a small gear-head motor, to track light sources vertically. Most of the circuitry was installed on small plug-boards from Radio Shack, mounted in a card rack below the CPU card. This rack could be tipped back 90 degrees to facilitate easier access for testing. In addition to motor driver circuits, there was a "Sweet Talker" speech synthesizer board so he could talk. Power came from a large "gel-cell" marine battery (for powering trolling motors on boats), which was slung near the ground in the center of the base. Two 6V lantern batteries (later replaced by a 12V motorcycle battery) provided separate power for the electronics. All motors were isolated from the electronics via relays and/or opto-isolators. After these pictures were taken, a set of metal panels was installed on the "facets" of the base, with lever switches behind them for collision sensing. A Polaroid sonar range-finder was also added later. If you check out the other photos of S.A.M., you will notice an "arm" sticking out the front. This was a prototype made from an old swing-arm desk lamp and some "fingers" from a robot hand design using brass tubing, bicycle chain, and 1/16" steel cable to allow natural bending of each finger. It was later replaced with a much heavier duty aluminum framework arm operated by two 12VDC linear actuators." – My Home Robot Projects, by Bill.

The Grass is Always Greener

You can find the accompanying video here!!

And finally, for our last post this week, let's go back in time to 2015, when I spent a significant amount of time documenting the former St Thomas Assembly plant!!

This incredible Italianate home which was built in 1872 was known as the Van Patter Home after the family that lived there for most of the 20th century. The house was named "Rhude" after the family's ancestral home in England and was built for Matthew Gilbert and his family. There is also another very similar house just down the street named "Gilbert Hall" that was built for William Gilbert. This house was a listed heritage property before its recent demolition. The home was a great example of the houses built in the area of Yarmouth during the 1870s and 1880s and reflect the affluence of this period of settlement.

This second house located across the street from the Van Patter Home was built for Lewis Gilbert in 1915. The two-storey red brick Foursquare house had an addition added to the north side of the home. It also featured a more modern single-storey addition to the front of the home and had been almost completely renovated inside.

Both of these homes along with many others in the area were recently demolished to make way for a brand new Volkswagen gigafactory. The plant which will be the size of 210 football fields will manufacture battery cells for the Volkswagen plants in both Tennessee and North Carolina.

In 2011 the St Thomas Assembly plant closed its doors for good, it was a 2.5 million square foot manufacturing plant owned by Ford with more than 1500 employees. It was producing Ford Crown Victorias, Mercury Grand Marquis and even Lincoln Town Cars for a short period before its closure. The last car on the line was a Crown Vic that was sent to Saudi Arabia. After the plant's demolition the site was purchased by Amazon to build a fulfillment centre. It may not be as large but maybe this new 2 million square foot gigafactory can bring manufacturing jobs back to a struggling small town.

The U.S. Department of Treasury’s gift to electric-vehicle shoppers (and global automakers) for the new year was to make many more EVs and plug-in hybrids eligible for the federal tax subsidy of up to $7,500 — including vehicles built outside North America — as long as drivers lease them or buy used rather than buy new.

EV credits and [rules] took effect Jan. 1.

One category extends the former credit of up to $7,500 for consumers buying new EVs and PHEVs, but it puts new limits on vehicle price and buyer income and will soon add requirements for the sourcing of EV batteries and materials. Additionally, since August [2022], it has required that the vehicles be assembled in North America.

A second is a new credit of up to $4,000 for buyers of used EVs.

A third is a “commercial” credit for businesses acquiring EVs. It offers up to $7,500 for light-duty vehicles (under 14,000 pounds) and up to $40,000 for heavier vehicles. Significantly, the commercial credit does not have the origin, price or other restrictions of the credit for consumer buyers.

On top of all that, the Department of Treasury guidance released at the end of December allows the less restrictive commercial credit to also apply to vehicles leased by consumers; that means most plug-in and fuel-cell EVs currently on the market can qualify, including those built in Europe or Asia. The credit goes to the leasing company — the vehicle owner — but it can be passed to the consumer in the form of lower lease payments.

The new federal rules do not affect state and local subsidies available for EV buyers [which may be able to get you even more savings].

cw: some robotgirl non-con/dub-con.

You take your robot girl's personality card out, and she goes ragdoll.

You clip it into the new adapter that just arrived from aliexpress, then dig through some drawers and pull out a few more personality cards, clicking them all into the slots. The whole assembly goes back into your robogirl's chassis, and you wait a moment for the diagnostic lights to turn green.

You pull out the remote from the dusty package, and stick in a fresh battery. A single button press and the adapter clicks, and an LED blinks a few times. You close up her chassis and and long-press the power button on the back of her neck.

All her servos jerk momentary, then the light in her eyes comes back. Unfocused eyes look around rapidly, then see you, and she smiles.

"Master! Are you done with my upgrade?" "I sure am, my pet. Want to see what I've added?" "Of course, master!".

You help her to her feet, then tell her to stay there. You step back, and click the remote. Her eyes go fuzzy for a second, then come back. She drops to all fours, tongue lolling out of her mouth. She pants, looking up at you expectantly. You pull a tennis ball from your pocket, and gently toss it out the open workshop door and down the hallway.

She excitedly arfs and races out the door, still on all fours. You hear her rooting around the packages waiting around the door, then she emits a muffled happy "yip!" and there's the sound of rapid quadrupedal footsteps as she scrambles back into the room. She kneels at your feet, dropping the slightly-wet tennis ball at your feet, and looking up at you, smiling as wide as she can but saying nothing.

You tap the remote, and again she seems to fuzz out of it for a moment, and you hear the soft click of a relay turning over inside her. She looks around in confusion, and gets back up on her feet. "Master, what... why did I do that? I remember searching for the ball and bringing it back to you, but I don't remember why I did that! It's like I'm remembering someone else's memories!"

You show her the flimsy piece of paper that came with the adapter, and she quickly scans the badly auto-translated english text.

TELPO PM-04 Personality Multiplexer

attach every personality cards into slots A, B, & C, D

insert the card proxy into any Syntek Central Unit (48 only pin)

On attached remote, button press to select toggle active personality card slot

Use only CR3220 cell

Memory Storage is reserved to slot A, other cards will share space

"A personality multiplexer, master?" she says, looking up at you with some confusion.

"Yep! I can swap your consciousness out for one of my choice. Slot B has this.". You hand her the small box, and she goes over it quickly, turning it over in her hands. It's covered in pictures of puppies, and advertises an accurate simulation of a loving "pupper", compatible with any Syntek chassis on the market.

"You turned me into a dog?!"

You rarely get her flustered enough to forget to address you properly. It's cute, though you'll have to punish her later for it. It might be your imagination, but you swear you can hear her fans spinning a little faster at the revelation...

"More or less. I pretty much just put you on pause, while letting a different personality take over your body. And I can do that at the click of a button!" You hold up the remote, showing her the four unlabeled buttons. "Want to see what's in slot C?" You reach towards the button, intentionally slowly...

She reaches out her arms "No! I mean, No thanks, master. Maybe I can look at the boxes first? I'd like to know more about what I'll be before we test it out."

You smile as devilishly as you can manage. "I don't know, that doesn't sound like something little dolls get to choose. Maybe you'd enjoy some time as a mindless sexbot?" Her already-big eyes manage to go wider, and she reaches forward for the remote impudently. You slam the button, and she stops mid-reach.

A moment later, she drops to her knees, and opens her mouth. She says nothing, as sexbots don't need speech synthesis routines. "I'm going to have a lot of fun with this", you think. Mainly in making her remember what you're going to make her do... You unzip your fly, and she leans forward hungrily.

Sustainable Living: Integrating Solar Energy into Your Home

Embracing renewable energy is a key step toward sustainable living, and solar energy stands at the forefront of this movement. Homeowners around the globe are harnessing the power of the sun, reducing carbon footprints, and enjoying the economic benefits of solar power. This article delves into the practicalities of integrating solar energy into your home, covering the essentials and the transformative impact it can have on how we live and power our daily lives.

Understanding Solar Energy

Solar energy is captured through photovoltaic (PV) cells that convert sunlight directly into electricity. These cells are assembled into panels, which can be installed on rooftops or in open land areas. When sunlight hits the PV cells, it triggers a flow of electrons, generating direct current (DC) electricity, which is then converted to alternating current (AC) for home use via an inverter.

Assessing Your Solar Potential

Before investing in solar technology, it's crucial to evaluate your home's solar potential. This depends on geographic location, roof orientation, shading from trees or buildings, and local weather conditions. Tools like Google's Project Sunroof or consultations with solar energy providers can offer insights into how much sunlight your rooftop can capture and convert.

Choosing the Right System

There's a range of solar panel systems available, from grid-tied setups that allow you to sell excess power back to the grid, to off-grid systems with battery storage for energy independence. Your choice will hinge on your energy goals, location, and financial considerations. Additionally, solar thermal systems can provide hot water or support heating systems, further reducing reliance on conventional energy sources.

Financial Considerations and Incentives

The initial cost of solar panel installation can be significant, but numerous government incentives, tax breaks, and rebates exist to make it more affordable. Over time, solar panels can pay for themselves through reduced electricity bills. Financing options like solar leases or power purchase agreements (PPAs) can also help homeowners adopt solar energy with little to no upfront costs.

Installation and Maintenance

Professional installation ensures optimal system performance and complies with local codes and regulations. Post-installation, solar panels require minimal maintenance, typically needing only occasional cleaning and checks to ensure no debris or damage. Most solar panels come with long-term warranties, reassuring homeowners of their durability and efficiency.

Environmental Impact

Integrating solar energy into your home is a positive step for the environment. It reduces reliance on fossil fuels, curtails greenhouse gas emissions, and contributes to a decrease in air pollution. As residential solar energy use grows, it aids in the collective effort to combat climate change and promotes a healthier planet.

Looking Ahead

Solar energy technology continues to advance, with improvements in efficiency, aesthetics, and integration with smart home technologies. As battery storage solutions become more affordable, the ability to store and manage energy will revolutionize home solar systems. By integrating solar energy into your home today, you're not just saving on costs but also investing in a sustainable future and joining the vanguard of the renewable energy revolution.

Toys for the rich that can cost less than a new Toyota Camry - before tax credits? You can get a brand new Chevy Bolt for $19k, cheaper than most sedans.

Even the cheapest Tesla, with federal tax credit, is $33k - that's $4k cheaper than a new Honda Odyssey (the classic mom van).

Electric cars give you range estimation. They also lie to you and save an extra 10-20 miles after their range estimates hit zero- after this you can't drive at highway speed and the car will drive slower and slower until you stop. You don't just run out. It depends on the manufacturer how exactly this is handled, but the car should be giving you tons of warnings well before you're in trouble. (And in OP's hypothetical, if you're on a mountain, driving downhill will recharge the battery.)

Yes, PV panels are not practical. This is largely because, as OP acknowledges, the area available vs the power density of sunlight is not great. Realistically, you can get about 200 W/m2 in strong sun and warm temps at solar noon with the panel facing the sun directly (which the panel on a roof of a car can't do unless many other things have gone wrong already). That's enough for - depending on the car - up to about one mile per hour per meter of panel in the best possible conditions. Which is something! Sometimes!

BUT it also costs money, adds reliability issues, introduces another potential expensive repair, only can help in some circumstances, and addresses an issue that (1) few drivers should be encountering and (2) the car tries quite hard to prevent you from reaching, which is why it's mainly super-luxury EVs that do it. It's flashy, expensive, and mostly useless.

1) Money. Normal solar panels that go on houses or in solar farms are mass-produced in standard shapes and sizes with standard frames and connections. They have standard quality and testing benchmarks that they've passed and they can more or less be made by the multimillions per year for barely more than the cost of raw materials. It's possible to shape thin solar cells to the roof of a car, which is, y'know, how some EVs do it, but it's far more expensive. The tools are bespoke and low-volume, you can't use the same cheap flat glass and standard aluminum framing, you have to re-test that it can stand up to rain and small hail and heat and high wind and all the other onslaughts that come with being on the roof of a car. The (optional) solar roof on a Hyundai Ioniq 5 adds >$1,000 to the purchase price while returning to you - at best - a whopping 3 miles per day if parked in full sun. Hyundai also offers solar cells on the most expensive Sonata hybrid - which will get you less than half a mile ler hour in full sun, but will set you back an extra $5,000. Cars that offer more than a few miles' worth per day are generally concept cars that'll set you back $100k or more, total, for up to ~40 miles. Cells are expensive and they don't gain you much.

2) Reliability and repair. On top of the purchase price, it's way more expensive to replace a panel with busted cells than to swap out a plastic body panel. There's more that can go wrong in assembly, it's harder to get replacement parts if you're in a crash, etc.

3) Solar panels are less effective when hot. When they're in the desert with free air circulation, that's one thing - if they're on top of the heat box that's a parked car? That's another. Much of the heating of a parked car happens through the windshields/windows (that's why putting a reflector up can drop the interior temps by 20 deg F or more). A parked car has the virtues of making the panels less efficient by tilting them away from the sun and heating them up. Batteries also cannot (safely) charge when over or under a limit temperature which varies with their chemistry. If you've heard a parked EV gently humming in the cold or heat, it's running its heat or AC to keep the battery at a safe temperature. This uses energy. So no, you may not even have more range at the end of a day of sitting in the sun - because energy is being used to keep the battery in its safe temperature range.

4) Many current consumer-affordable EVs can regain >100 miles of charge in less than 20 min on a fast charger and even >50 in 5 minutes.

5) If you're regularly cutting it that close on charging, you're really hurting your battery. You should not be doing that. Batteries degrade much faster when discharged to 0% than they do when discharged down to 20%. This has to do with the chemistry of the batteries and I can't go into huge detail here, but it's a similar phenomenon as why draining your regular car battery beyond its min state can destroy it permanently. Your battery will last far longer if you charge and discharge it small amounts more frequently than if you take it down to 0 and back to 100%. This is also true for e.g. laptop and phone batteries.

6) you CAN get electricity and bring it back. it's called a portable battery. some roadside service providers carry them. you can buy one. if your roadside service provider doesn't offer this, they can tow you home, which is far less expensive than a whole solar roof and far faster than waiting for two days for your car to charge.

even though people regularly have to get gas cars jumpstarted because they left the headlights on and the starting battery died - or because it got cold - and even though gas cars get hot in the sun, we do not cover gas cars in solar panels. because it's far more expensive and technically troublesome than it's worth.

Okay also I’ve been driving electric cars long enough now to be really emphatic that the fact that they’re not all automatically built with solar panels in the roofs is a scandal.

And somehow almost every time I tell anyone this they roll their eyes and attempt to explain to me that this would not create a perpetual motion machine because of the limitations of the area relative to the power draw of the motor, which is incredibly annoying because that’s not the point.

Yes it’s possible that driving in the sunshine with a solar collector dripping into the battery would net you a little more mileage on that trip before needing recharge, but the usefulness of a solar-topped electric car is that if you drive it someplace–say, to work–and leave it outside in the sun all day, you’ll definitely have more range available by the time you’re ready to head home.

Also if you fuck up your calculations because of the inefficiency induced by cold weather or something and get yourself stranded without anywhere to charge, like halfway up a mountain or, more likely, six miles from home, you can call for rescue or walk away, come back later, and it’ll be able to move again.

This is important because unlike running out of gas you can’t really go get some electricity.

Streamlining Lithium-Ion Battery Pack Line Processes: Challenges and Solutions

The packaging and assembly of lithium-ion battery packs are crucial in the field of energy storage and have a significant impact on applications like electric vehicles and electronics.

The pack line process consists of three main phases: production, assembly, and packaging.

The pack is a complex system comprising battery packs, shunts, soft connections, protective boards, outer packaging, output components (such as connectors), insulating materials like barley paper, plastic brackets, and other auxiliary materials. These components come together to form a complete pack unit. This blog discusses the challenges faced in the Lithium-Ion Battery Pack Line Processes and offers potential solutions.

The Core Functions of a Pack Line

A typical production line for battery packs serves two main purposes: transmission and testing. In the industry, it is common to use semi-automatic assembly lines for pack production. These lines handle tasks such as launching, offline operations, testing, in-plant transmission, and packaging. The processes involved in a lithium battery pack production line are relatively simple, including feeding, attaching brackets, welding, and conducting thorough testing, among other steps.

Challenges in Meeting Pack Line Requirements

Highly Customized Demands: The power battery system pack requires targeted research and development tailored to the specific requirements of vehicle manufacturers. Each automaker has unique specifications and needs, leading to a high degree of customization in the assembly process. These drive increased demand for automated production lines that can efficiently adapt to these variations.

Stringent Safety and Stability Prerequisites: The core challenge in creating a power battery system pack lies in accommodating the customized market demands of different vehicle models. This customization process addresses various aspects, including BMS design, thermal management, space constraints, structural strength, system interfaces, IP ratings, and safety measures. These custom requirements are vital for ensuring the safety and stability of the battery pack.

Precise Control of Production Rate: Modern battery pack production requires a different approach to maintain a high and efficient production rate while meeting market supply and demand. This involves refining the process to manage the “whole line beat,” focusing on average workstation working time rather than a sequential production line.

Enhanced Compatibility: The evolving lithium battery industry adds complexity to the production process. With non-standardized modules, incoming cells, shells, PCB boards, and connecting components, compatibility across the production line becomes crucial. Adapting to these changes and ensuring efficiency and compatibility is vital.

Embracing Automation and Innovation: In response to the growing lithium power industry, leaders are expanding production capacity, optimizing pack line processes, and incorporating smart technologies. This includes integrating intelligent equipment, robotic arms, collaborative robots, mobile robots, and other advanced technologies to improve efficiency.

The lithium battery manufacturing process requires highly reliable, stable, and precise equipment for process control. It also demands intelligent data processing capabilities for effective production data management. This drives the need for automation and intelligent upgrades to meet the evolving demands of the industry.

As the energy storage landscape evolves, automating and enhancing pack line processes is crucial to ensure reliable, stable, and precise equipment. This streamlines production for the intelligent and data-driven future of lithium-ion battery manufacturing.

The Grass is Always Greener

You can find the accompanying video here!!

Moving across the road, in today's post, we will visit this classic red brick farmhouse!!

This incredible Italianate home which was built in 1872 was known as the Van Patter Home after the family that lived there for most of the 20th century. The house was named "Rhude" after the family's ancestral home in England and was built for Matthew Gilbert and his family. There is also another very similar house just down the street named "Gilbert Hall" that was built for William Gilbert. This house was a listed heritage property before its recent demolition. The home was a great example of the houses built in the area of Yarmouth during the 1870s and 1880s and reflect the affluence of this period of settlement.

This second house located across the street from the Van Patter Home was built for Lewis Gilbert in 1915. The two-storey red brick Foursquare house had an addition added to the north side of the home. It also featured a more modern single-storey addition to the front of the home and had been almost completely renovated inside.

Both of these homes along with many others in the area were recently demolished to make way for a brand new Volkswagen gigafactory. The plant which will be the size of 210 football fields will manufacture battery cells for the Volkswagen plants in both Tennessee and North Carolina.

In 2011 the St Thomas Assembly plant closed its doors for good, it was a 2.5 million square foot manufacturing plant owned by Ford with more than 1500 employees. It was producing Ford Crown Victorias, Mercury Grand Marquis and even Lincoln Town Cars for a short period before its closure. The last car on the line was a Crown Vic that was sent to Saudi Arabia. After the plant's demolition the site was purchased by Amazon to build a fulfillment centre. It may not be as large but maybe this new 2 million square foot gigafactory can bring manufacturing jobs back to a struggling small town.
