[In February, 2023], a small warehouse in the English city of Nottingham received the crucial final components for a project that leverages the power of used EV batteries to create a new kind of circular economy.

Inside, city authorities have installed 40 two-way electric vehicle chargers that are connected to solar panels and a pioneering battery energy storage system, which will together power a number of on-site facilities and a fleet of 200 municipal vehicles while simultaneously helping to decarbonize the UK’s electrical grid.

Each day Nottingham will send a combination of solar-generated energy — and whatever is left in the vehicles after the day’s use — from its storage devices into the national grid.  The so-called “vehicle to grid” chargers deliver this energy just when it’s needed most, during peak evening demand, when people are home cooking, using hot water or watching TV. Later, the same chargers pull energy from the grid to recharge the vehicles in the wee hours of the night, when folks are sleeping and electricity is cheaper and plentiful.

“We are trying to create a virtual power station,” says Steve Cornes, Nottingham City Council’s Technical Lead. “The solar power and battery storage will help us operate independently and outside of peak times, making our system more resilient and reducing stress on the national grid. We could even make a profit.” ...

After around a decade, an EV battery no longer provides sufficient performance for car journeys. However, they still can retain up to 80 percent of their original capacity, and with this great remaining power comes great reusability.

“As the batteries degrade, they lose their usefulness for vehicles,” says Matthew Lumsden, chairman of Connected Energy. “But batteries can be used for so many other things, and to not do so results in waste and more mining of natural resources.”

The E-STOR hubs come in the form of 20-foot modular containers, each one packed with 24 repurposed EV batteries from Renault cars. Each hub can provide up to 300kW of power, enough to provide energy to dozens of homes. One study by Lancaster University, commissioned by Connected Energy, calculated that a second life battery system saved 450 tons of CO2 per MWh over its lifetime...

Battery repurposing and recycling is set to play a massive role over the coming years as the automobile industry attempts to decarbonize and the world more broadly attempts to fight waste. The production of EVs, which use lithium-ion batteries, is accelerating. Tesla, for example, is aiming to sell 20 million EVs per year by 2030 — more than 13 times the current level. In turn, 12 million tons of EV batteries could become available for reuse by 2030, according to one estimate.

“Over the next decade we are going to see this gigantic wave,” says Jessica Dunn, a senior analyst at the Union of Concerned Scientists. “Companies are recognizing this is a necessary industry. They need to ramp up infrastructure for recycling and reuse.”

PSA ABOUT ELECTRIC VEHICLES

IF YOU OWN AN ELECTRIC VEHICLE AND ARE IN THE PATH OF AN ONCOMING HURRICANE AND CANNOT EVACUATE

DO NOT PARK YOUR CAR IN YOUR HOUSE

heavy hurricanes like helene and milton will bring floods of saltwater with them. saltwater is corrosive towards the lithium ion batteries found in ALL ELECTRIC VEHICLES and can cause the batteries to short-circuit, fail, or even explode. lithium ion fires take THOUSANDS more gallons of water to put out than normal electrical fires. they can and will burn houses down even during hurricanes.

PARK YOUR ELECTRIC VEHICLES ON THE STREET.

How does an engine contribute to a car's powertrain?

The powertrain in a vehicle is the system responsible for generating power and delivering it to the wheels to propel the vehicle forward. The operation of a powertrain can vary depending on whether the vehicle is powered by an internal combustion engine (ICE) or an electric motor (in the case of electric vehicles). Here's a general overview of how a powertrain works in both types of vehicles:

Internal Combustion Engine (ICE) Vehicle - Combustion Process: In an ICE vehicle, the powertrain starts with the combustion process in the engine. Fuel (gasoline or diesel) mixes with air in the combustion chamber and is ignited by spark plugs (in gasoline engines) or compression (in diesel engines).

Power Generation: The combustion process generates energy in the form of mechanical power, causing pistons to move up and down within the cylinders of the engine. This motion drives the crankshaft, converting linear motion into rotational motion.

Transmission: The rotational motion from the crankshaft is transmitted to the transmission, which consists of gears that allow the driver to select different ratios (speeds). This enables the engine to operate efficiently across a range of vehicle speeds.

Drivetrain: The transmission sends power to the drivetrain components, including the driveshaft, differential, and axles, which transfer power to the wheels. The differential allows the wheels to rotate at different speeds, enabling smooth turns.

Wheel Movement: The power transmitted through the drivetrain causes the wheels to rotate, propelling the vehicle forward or backward depending on the gear selection and throttle input from the driver.

Electric Vehicle (EV) -

Battery Pack: The primary source of power for the EV, storing electricity in chemical form.Powers the electric motor and provides electricity for all electronic devices within the EV.

Battery Management System (BMS): Monitors battery cell conditions, including voltage, current, temperature, and state of charge (SoC).It protects the battery against overcharging, deep discharging, and overheating and helps balance the charge across cells. Ensures optimal performance and longevity of the battery by regulating its environment.

Inverter: Converts DC from the battery pack into AC to drive the electric motor.Adjusts the frequency and amplitude of the AC output to control the motor’s speed and torque. Critical for translating electrical energy into mechanical energy efficiently.

Onboard Charger: Facilitates the conversion of external AC (from the grid) to DC to charge the battery pack. Integrated within the vehicle, allowing for charging from standard electrical outlets or specialized EV charging stations. Manages charging rate based on battery status to ensure safe and efficient charging.

DC-DC Converter: Steps down the high-voltage DC from the battery pack to the lower-voltage DC needed for the vehicle's auxiliary systems, such as lighting, infotainment, and climate control. Ensures compatibility between the high-voltage battery system and low-voltage electronic components.

Electric Motor: Converts electrical energy into mechanical energy to propel the vehicle. It can be of various types, such as induction motors or permanent magnet synchronous motors, each offering different efficiencies and characteristics. Typically provides instant torque, resulting in rapid acceleration.

Vehicle Control Unit (VCU): The central computer or electronic control unit (ECU) that governs the EV's systems. Processes inputs from the vehicle’s sensors and driver inputs to manage power delivery, regenerative braking, and vehicle dynamics. Ensures optimal performance, energy efficiency, and safety.

Power Distribution Unit (PDU): Manages electrical power distribution from the battery to the EV’s various systems. Ensures that components such as the electric motor, onboard charger, and DC-DC converter receive the power they need to operate efficiently. Protects the vehicle's electrical systems by regulating current flow and preventing electrical faults.

In both ICE vehicles and EVs, the powertrain's components work together to convert energy into motion, enabling the vehicle to move efficiently and effectively. However, the specific technologies and processes involved differ significantly between the two propulsion systems.

"Cobalt Red": Smartphones & Electric Cars Rely on Toxic Mineral Mined in Congo

The Democratic Republic of the Congo produces nearly three-quarters of the world's cobalt, an essential component in rechargeable batteries powering laptops, smartphones and electric vehicles. 

But those who dig up the valuable mineral often work in horrific and dangerous conditions, says Siddharth Kara, an international expert on modern-day slavery and author of _Cobalt Red: How the Blood of the Congo Powers Our Lives_. 

In an in-depth interview, he says the major technology companies that rely on this cobalt from DRC to make their products are turning a blind eye to the human toll and falsely claiming their supply chains are free from abuse, including widespread child labor.

 "The public health catastrophe on top of the human rights violence on top of the environmental destruction is unlike anything we've ever seen in the modern context," says Kara. "The fact that it is linked to companies worth trillions and that our lives depend on this enormous violence has to be dealt with."
