+++Serbatoio auto elettriche+++

Come è noto, la tecnologia BEV – Battery Electric Vehicles, le auto a pile insomma! - prevede l’utilizzo di batterie a ioni di litio per accumulare l’energia necessaria per conferire all’auto la sua autonomia in termini di km percorribili.

Il pacco batterie è quindi il vero e proprio “serbatoio” dell’auto a pile ma, a differenza di quello delle auto a motore endotermico, è tutt’altro che un semplice contenitore di idrocarburi ma il complesso frutto di tecnologie sofisticate che portano al prodotto finito. ⤵️

Vediamo quindi l’impatto ambientale ed energetico per la sua costruzione e, per semplicità, supponiamo che esso sia pari a 50 kWh.

Al netto del suo insopportabile bias woke, interrogando chatGPT sui dati salienti relativi al processo di estrazione/raffinazione del litio e alla costruzione delle batterie, l’algoritmo AI mi ha fornito i seguenti dati:

1. Per un pacco batterie da 50 kWh occorrono circa 15 kg di litio.

2. Per estrarre 1 kg di litio occorre scavare fino a 5 tonnellate di roccia spendendo fino a 15.000 MJ di energia, più ulteriori 5.000 MJ per raffinare il metallo estraendolo dalla salamoia risultante. Un totale di 20.000 MJ/kg, equivalenti a 5,6 MWh/kg.

3. Sicché, per estrarre il litio necessario per fabbricare il nostro bravo pacco batterie dovremo scavare 75 tonnellate di roccia e utilizzare tanta tanta acqua, nell’ordine di 1.800 litri/kg, cioè 27.000 litri (che dicono quelli dell’acqua delle bistecche?). Inoltre, dovremo spendere un’energia di 84 MWh circa. A questa va poi sommata l’energia necessaria per costruire il pacco batterie vero e proprio che, a detta di chatGPT, si aggira il intorno ai 250 kWh per ogni kWh di capacità, sicché ulteriori 12,5 MWh.

4. Ricapitolando, il “serbatoio” di un’auto a pile implica la necessità di scavare 75 tonnellate di roccia, utilizzare (“consumare”? “sprecare”?) 27.000 litri d’acqua e spendere 96,5 MWh di energia.

In altre parole, l’auto a pile parte con un handicap di devastazione ambientale e un consumo di energia per la costruzione del solo "serbatoio" che non hanno eguali con un’auto a motore endotermico.

Dulcis in fundo, sapete a quanti litri di gasolio corrisponde l'energia meccanica di 96,5 MWh spesa per produrre il solo pacco batterie? 27.600 litri di gasolio, con i quali un’auto degna di questo nome potrebbe percorrere fino a 500.000 km!

Why are obstacles on the tracks a problem?

Previously, I mentioned that when a train encounters an obstacle on the line such as a tree branch, what happens is a complicated physics process that results in the train pushing the branch along the line. Here I will explain that process, but be aware that complicated physics things are about to happen. There are some pretty diagrams to look at though, so if you want you can look at those and then skip to the end for a summary. They're even in color!!

First of all, some basic setup (before putting some numbers in):

We have a train travelling at an initial velocity u, with mass M, and an engine capable of producing a constant power P (we will use this to restore the train's velocity to u if it decreases for some reason).

The train encounters an obstacle on the line, such as a tree branch of mass m. We will assume (for now) that the collision is elastic - that is, no energy was lost (for instance, as sound).

We are also assuming a frictionless vacuum, cylindrical tree branch, and rectangular train.

To start with, we look at conservation of momentum (figure 1):

Since the train has elastically collided with a branch, its speed is reduced, given as Vtrain . As trains are typically much heavier than a single tree branch, we take M >> m, and so Vtrain ≈ u.

However, this is somewhat unrealistic, as when a train hits an obstacle, energy is lost –as a crunch sound, for instance– so it may be more appropriate to assume an inelastic collision. Since I said that the branch sticks to the train (and I am right), we should assume a completely inelastic collision, where as much kinetic energy as possible is lost.

Again, we look at conservation of momentum (figure 2):

In this case, if we again assume M>>m, we still get v ≈ u.

Since we know from reality that problems will happen if the train collides with the branch, this tells us that we have made an unrealistic assumption somewhere. In this case, it must be the assumption that the train's mass, M, is large enough that the branch's mass m can be ignored. So, without this assumption, we look at how long it takes the train to get back to its initial speed, using the equations for motion under constant power (equations derived from Taylor, 1930 and shown in figure 3):

To find how much energy is used in each case, simply multiply the time by the power.

By now, you may be wondering what the point of all this is – after all, I haven't actually shown you if this is meaningful. So let's add some numbers to this and see how reasonable all of our assumptions were!

If we take the train's mass to be M=30 tonnes (30,000kg), its power P=1500kW, and its initial speed u=40 m/s (144 km/hr) respectively; and assume the branch has a mass m=5kg (that seems reasonable, right? Trees are mostly water, which is 1kg per cubic meter, and if it has a radius of 0.5m and a length of 1.435m, it should be about that much), we can calculate all the various things we need:

First, the final velocity of the train and branch in the inelastic case (see figure 2 for the equation):

v≈39.99m/s which is pretty close to the initial velocity.

The time taken to return to speed (fig. 3) for the train/branch system is:

t≈0.0053s

This is quite fast, but hold on: the energy used to do this is about 8000 joules, which is probably quite expensive at current electricity prices, but those are given in kWh and I really don't feel like converting between them. (8000 is a big number, right?)

For the elastic case, things are a little bit more complicated, as we have two different velocities to calculate (figure 4):

If you were just looking at the pictures and are upset that the last two have been equations, don't worry, the next one isn't.

Vbranch ≈ 79.99 m/s

Vtrain ≈ 39.98 m/s

The time taken to return to speed:

t≈0.0094s

This is almost double that of the inelastic case, resulting in the energy used increasing to the enormous –and probably expensive– value of 14 kJ. (I even needed to use an SI prefix this time! And one of the ones that makes things bigger!)

However, both of these cases also reveal some interesting things about the situation: the elastic case has the tree branch launched away from the train at 80m/s, which is about 288 km/hr. Since the train and branch are likely irregularly shaped, the branch probably won't be pushed along the tracks at 290km/hr, and could instead be launched into the air space towards you. Nobody wants to be in the situation where a tree branch is flying towards you at almost 300 km/hr. I could do some math to see how much it would hurt, or if you could reasonably expect to dodge it, but I think we can just assume it will be quite painful.

Historically, trains avoided flinging branches at nearby passengers at almost 500km/hr (that's half the speed of sound) by employing a triangular device on the front of the train to deflect objects such as cows off the tracks. These were particularly common in North America, where lineside fences have yet to be discovered outside of the Northeast Corridor and it is easy for things to wander onto the tracks. However, thanks to innovations by the Budd company and others, more recent american trains are basically indestructible, rendering obstacle deflectors unnecessary. The effects of the obstacle deflector are shown below (figure 5):

This device is known in America as a burgerizer, since it can provide an easy meal for the train crew –two of the five ingredients for a cheeseburger right on the front of the train, more if you're lucky– although since usually the obstacle is shoved off the track, the British name of "cowcatcher" is misleading, especially if you hit a truck instead. The burgerizer's physics can easily be calculated using conservation of momentum, but this involves vectors, and I don't want to deal with vectors right now is left as an excercise for the reader.

In the inelastic case, we note that the branch sticks to the front of the train. Since the inelastic case is more realistic (I will not justify this statement), this means that other things will also stick to the train. By the time the train reaches the end of the line, the mass of the things stuck to it may end up not being negligible (figure 6):

If the train is electric, this will strain the power grid and could lead to power cuts elsewhere as more energy is given to keep the train running at speed. If the train is diesel, it will be unable to provide constant power and could slow down (an electric train has access to every power station in the country if the need arises, a diesel train just has its onboard generator or motor AND a limited amount of fuel).

This mess is also difficult to clean up, and could damage the track as it is pushed along. Also, although we have been ignoring friction (since trains have very little rolling resistance) this pile of stuff will cause friction to be very noticeable, and could even obstruct the driver's visibility – potentially leading to more collisions.

–//–

Now that you have read through all of the calculations (or looked at the pictures and skipped the rest), you should have a thorough understanding of why we have to stop trains to clear things off the line, and can't just plow through them like in the movies. (I assume this happens in movies, I have not checked)

TL;DR: When the train hits a branch, either the branch goes flying towards you really quickly, at basically 1000km/hr, which is approximately the speed of sound; or it sticks to the front of the train and becomes part of a massive pile of things that gets in the way and slows down the train.

Finally:

I put the images together using the shapes in my computer's word processor (except the various rail logos); while the equations of motion under constant power are from this paper by Lloyd W. Taylor (published in 1930, I believe). Also thanks to @cosmos-dot-semicolon for peer reviewing this, any errors are not my fault.

Inquina di più una Fiat 500 d'epoca o una Fiat 500 moderna? Sorpresa....

Inquinamento, marmitte catalitiche, filtri antiparticolato, ma siamo sicuri che un auto nuova inquini meno che una vecchia 500?

In questi anni tutta l'informazione ci ha convinto che le vecchi automobili, come le nostre Fiat 500 d'epoca,  sono molto inquinanti e che occorre utilizzare auto moderne con iniezione elettronica, marmitta catalitica, filtri antiparticolato e adesso, perfino le auto elettriche, per ridurre l'inquinamento. Peccato che in realtà l'inquinamento in questi ultimi dieci anni sia solo aumentato Ma come? Abbiamo fatto tanto, come mai? Oggi si scopre che a produrre l'inquinamento nelle città sono le pastiglie dei freni (le fiat 500 d'epoca hanno i tamburi, quindi non inquinano) e il rotolamento degli pneumatici. Ovviamente i 500 Kg del Cinquino producono meno attrito dei 1300 -1800 Kg delle auto circolanti, a maggior ragione di quelle elettriche, che pesano molto di più. Abbiamo voluto essere scientifici e fare un pò di conti e di confronti: Fiat 500 Epoca Emissioni di PM10: Motore: 0.01125 g per 100 km. Rotolamento: 5 mg/km×100 km=0.5 g5mg/km×100km=0.5g Totale PM10: 0.01125 g + 0.5 g = 0.51125 g. Emissioni di PM2.5: Motore: 0.007875 g per 100 km. Rotolamento: 2.5 mg/km×100 km=0.25 g2.5mg/km×100km=0.25g Totale PM2.5: 0.007875 g + 0.25 g = 0.257875 g. Le emissioni totali per 100 km della Fiat 500 d'epoca sono circa 0.51125 g per PM10 e 0.257875 g per PM2.5. Fiat 500 2023 Emissioni di PM10: Motore: 0.015 g/km × 100 km = 1.5 g. Rotolamento: 10 mg/km × 100 km = 1 g. Frenata: 20 mg/km × 100 km = 2 g. Totale PM10: 1.5 g + 1 g + 2 g = 4.5 g per 100 km. Emissioni di PM2.5: Motore: 0.0075 g/km × 100 km = 0.75 g. Rotolamento: 5 mg/km × 100 km = 0.5 g. Frenata: 10 mg/km × 100 km = 1 g. Totale PM2.5: 0.75 g + 0.5 g + 1 g = 2.25 g per 100 km. Per un'auto di 1300 kg con specifiche Euro 4, pneumatici 175/65R14 e freni a disco sul due ruote, le emissioni totali stimare per 100 km sono di circa 3 g di PM10 e 1,5 g di PM2.5.

Ma ne vogliamo parlare !?

Purtroppo non avendo la marmitta catalitica, la vecchia Cinquecento emette Benzene (Circa 0.007 grammi per 100 km)

Ma la cosa più importante è un'altra: per produrre un auto nuova, quanta C02 si produce? Quanto PM 10, PM2,5 a altri inquinanti vengono prodotti? Per costruire un auto nuova servono qualcosa come 30.000 kW di energia.  Vengono altresì prodotti 15 Kg di Ossidi di Azoto (NOx), 7Kg di Ossido di Zolfo (SOx),  circa 5 kg di PM10 e PM2.5 (ci vogliono 10000 Km in giro con le nostre Fiat 500 d'epoca per fare altrettanto!)  e sopratutto 6-8 tonnellate di CO2 per veicolo (!) Se poi parliamo di auto elettriche, il solo pacco batteria richiede: Energia: 2100 kWh CO2: 2.1 tonnellate + 0.315 tonnellate (smaltimento) = 2.415 tonnellate NOx: 2.4 kg SOx: 1.2 kg PM10/PM2.5: 0.6 kg COV: 0.24 kg Metalli pesanti: 0.06 kg

Quindi, siamo sicuri che le nostre Fiat 500 d'epoca inquinino?

Queste cose sono da tenere presente e da sapere quando si sentono notizie non tanto vere sull'inquinamento e quando vengono fatte le solite proposte di impedire la circolazione della auto d'epoca. Se si fosse fatta attenzione a creare auto più durature (ma questo va contro ogni forma business) avremmo molto meno inquinamento. Voi cosa ne pensate? Mi piacerebbe avere i vostri commenti.

Combien de temps faut-il pour charger une voiture électrique ?

Un guide complet sur le temps nécessaire pour charger une voiture électrique, les facteurs qui influencent le temps de charge et le concept de recharge d'appoint.

Résumé

Le temps nécessaire pour charger une voiture électrique peut être aussi court que 30 minutes ou plus de 12 heures. Cela dépend de la taille de la batterie et de la vitesse du point de charge. Une voiture électrique classique (batterie de 60 kWh) prend un peu moins de 8 heures pour se recharger de vide à plein avec un point de charge de 7 kW.

La plupart des conducteurs rechargent leur batterie plutôt que d'attendre que leur batterie se recharge de vide à plein.

Pour de nombreuses voitures électriques, vous pouvez ajouter jusqu'à 160 km d'autonomie en environ 35 minutes avec un chargeur rapide de 50 kW. Plus la batterie de votre voiture est grande et plus le point de charge est lent, plus il faut de temps pour la recharger de vide à plein.

Conseil : recharger une voiture électrique est similaire à charger un téléphone portable : vous le rechargez pendant la journée si vous en avez besoin et vous le rechargez complètement à la maison pendant la nuit.

Combien de temps faut-il pour charger complètement une voiture électrique ?

Temps de charge complet à vide avec différentes vitesses de borne de recharge : Vous ne trouvez pas le modèle que vous recherchez dans ce tableau ? Parcourez d'autres véhicules électriques ici.

En savoir plus sur la recharge à domicile des véhicules électriques.

* L'autonomie de confiance des points de recharge est la distance maximale que nous pouvons parcourir en toute confiance avec l'énergie électrique entre deux charges. L'autonomie réelle dépend de divers facteurs, notamment les conditions de conduite, le style de conduite personnel, la température extérieure, le chauffage/la climatisation, etc.

** Les chiffres indiqués concernent l'autonomie standard de la Tesla Model S d'entrée de gamme.

*** Le temps de charge peut être limité par la vitesse de charge maximale du véhicule électrique.

À quelle vitesse les voitures électriques se chargent-elles ?

Les chargeurs rapides (43-50 kW et 150 kW) sont le moyen le plus rapide de charger les véhicules électriques : par exemple, ils peuvent charger une Nissan LEAF (2018) en 1 heure ou moins, une Tesla Model S (2019) en 2 heures ou moins et un Mitsubishi Outlander PHEV (2018) en 40 minutes.

Les bornes de recharge à domicile ont généralement une puissance nominale de 3,7 kW ou 7 kW : ces chargeurs prennent 11 à 21 heures pour une charge complète pour la Tesla Model S (2019), 4 à 11 heures pour la Nissan LEAF (2018) et 4 heures pour le Mitsubishi Outlander PH

V (2018).

Toutes les voitures électriques peuvent se recharger sur des bornes de recharge compatibles avec un taux de charge maximal supérieur à celui qu'elles peuvent supporter : Voir aussi „ Borne de recharge pour voiture électrique : tarifs, consommation et durée de charge»

Elles se rechargeront au taux maximal qu'elles peuvent accepter, offrant une flexibilité dans les options de charge, comme l'utilisation d'un chargeur rapide de 22 kW, qui peut charger les véhicules mentionnés en 4 à 6 heures.

Astuce : presque toutes les voitures électriques à batterie pleine peuvent se recharger rapidement, la plupart des voitures électriques hybrides rechargeables ne le peuvent pas.

Combien de temps faut-il pour recharger une voiture électrique sur une borne de recharge ?

Il peut falloir à peine 30 minutes ou moins pour charger une voiture électrique classique (batterie de 60 kWh) sur une borne de recharge rapide de 150 kW, de vide à plein. Si vous utilisez un chargeur public de 7 kW, vous pouvez vous attendre à atteindre la même autonomie en moins de 8 heures et environ 3 heures avec une borne de recharge de 22 kW.

Un chargeur rapide offrira le temps de charge le plus rapide au coût le plus élevé, ce qui est idéal si vous êtes sur la route et souhaitez poursuivre votre voyage. Si vous n’êtes pas pressé, l’utilisation d’un chargeur de puissance inférieure sera moins chère. Vous pouvez laisser votre voiture se recharger pendant la nuit ou pendant que vous faites quelques courses.

Combien de temps faut-il pour charger une voiture électrique à la maison ?

Un chargeur domestique de 7 kW chargera une batterie de voiture électrique typique de 60 kWh de vide à pleine en un peu moins de 8 heures. Le temps idéal pour recharger complètement la batterie de votre VE pendant que vous dormez. Un chargeur domestique plus lent de 3,7 kW prendrait environ 16 heures pour faire la même chose.

Des chargeurs domestiques de 22 kW sont parfois disponibles, mais ils sont rarement utilisés à cette fin. Bien qu'ils offrent une charge plus rapide que les chargeurs de puissance inférieure, leur installation et leur fonctionnement nécessitent une alimentation triphasée, ce qui n'est pas courant dans les propriétés résidentielles et est coûteux à mettre en œuvre.

Astuce : la recharge à domicile s'effectue de préférence via une borne de recharge dédiée. Découvrez les avantages d'un chargeur domestique.

Qu'est-ce que la recharge d'appoint ?

La plupart des conducteurs de voitures électriques se branchent pour recharger leur véhicule lorsqu’ils se garent, que ce soit chez eux pendant la nuit ou pendant la journée au supermarché, à la salle de sport ou sur leur lieu de travail.

C’est ce qu’on appelle la recharge d’appoint. Au lieu de laisser la batterie se vider et d’attendre qu’elle se recharge complètement, les conducteurs profitent du temps où leur voiture est garée (soit environ 95 % du temps) pour garder la batterie chargée.

Les bornes de recharge publiques et sur les lieux de travail ont généralement une puissance comprise entre 7 et 22 kW, ce qui les rend idéales pour la recharge d’appoint. Découvrez comment accéder à la recharge publique dans notre guide. Combiner la recharge d’appoint en journée avec la recharge de nuit à domicile est un moyen efficace de garder votre voiture électrique chargée et prête à partir.

Conseil : les conducteurs de voitures électriques ne se soucient pas beaucoup du temps qu’il faut pour charger la voiture. Il est plus utile pour eux de savoir combien de kilomètres d’autonomie ils obtiendront lorsqu’ils la brancheront pour la recharger.

Quelle autonomie obtenez-vous par heure de charge ?

En tant que conducteur de véhicule électrique, il est utile de savoir combien de kilomètres d'autonomie vous obtenez pendant que votre véhicule est en charge afin de savoir si vous pouvez atteindre votre prochaine destination.

Kilomètres d'autonomie ajoutés par heure de charge

3,7 kW lent 7 kW rapide 22 kW rapide 43-50 kW rapide 150 kW rapide

Jusqu'à 15 miles Jusqu'à 30 miles Jusqu'à 90 miles Jusqu'à 90 miles en 30 min Jusqu'à 200 miles en 30 min

Analyse :

L'autonomie par heure varie en fonction de l'efficacité de votre voiture. Les petites voitures électriques à batterie complète (par exemple, Renault Zoe) sont les plus efficaces et bénéficient d'une autonomie de 30 miles par heure en chargeant à 7 kW.

Les plus grosses voitures électriques à batterie complète (par exemple, Audi e-tron Quattro) sont plus lourdes et bénéficient d'une autonomie d'environ 20 miles par heure à 7 kW. (Les véhicules hybrides rechargeables sont généralement moins efficaces que les véhicules électriques à batterie complète).

L'efficacité d'une voiture dépend également de facteurs environnementaux tels que la température. Cela signifie que les voitures électriques sont plus efficaces et ont une autonomie légèrement meilleure par heure en été qu'en hiver. Facteurs qui affectent la vitesse de charge - Il existe 5 facteurs principaux qui affectent le temps nécessaire pour charger un véhicule électrique.

Taille de la batterie : Plus la capacité de la batterie de votre véhicule est grande (mesurée en kWh), plus la charge sera longue. État de la batterie (vide ou pleine) : Si vous chargez à partir d'une batterie vide, la charge prendra plus de temps que si vous la rechargez à partir de 50 %.

Taux de charge maximal du véhicule : Vous ne pouvez charger la batterie d'un véhicule qu'au taux de charge maximal que le véhicule peut accepter. Par exemple, si le taux de charge maximal de votre véhicule est de 7 kW, vous ne chargerez pas plus rapidement en utilisant une borne de recharge de 22 kW.

Taux de charge maximal du point de charge : Le temps de charge sera également limité par le taux de charge maximal du point de charge que vous utilisez. Par exemple ; même si votre véhicule peut se recharger à 11 kW, il ne se rechargera qu'à 7 kW sur une borne de recharge de 7 kW.

Facteurs environnementaux : une température ambiante plus froide peut allonger légèrement la durée de charge, en particulier si vous utilisez un chargeur rapide. Les températures plus froides signifient également que les véhicules sont moins efficaces, ce qui signifie que moins de kilomètres sont ajoutés à chaque fois que vous chargez.

Astuce : par temps froid, la mise à température de l'habitacle (et de la batterie) consomme de l'énergie qui n'est pas utilisée pour faire fonctionner la voiture. Si la voiture chauffe puis refroidit régulièrement après de courts trajets, vous consommez beaucoup plus d'énergie et votre autonomie diminue considérablement. Il est donc judicieux d'utiliser des recharges d'appoint régulières. Sur les trajets plus longs, les effets du froid sont moins prononcés, mais toujours perceptibles.

Ashok Leyland Circuit S: Another popular choice, starting from ₹1.5 crore, known for its swappable battery technology and lower maintenance requirements.

International vs. Local Manufacturers:

Local manufacturers like Tata Motors and Ashok Leyland provide competitive pricing compared to international brands, which can range from ₹2.5 crore to ₹4 crore depending on the technology and features offered.

Factors Influencing Pricing

Several key factors affect the final price of electric buses in India:

Battery Pack Size: The size of the battery significantly impacts cost:

Small capacity (150-200 kWh): Lower initial cost but limited range.

Medium capacity (250-300 kWh): A balance of range and cost.

Large capacity (350+ kWh): Higher cost but maximum range.

Range Capabilities:

Short-range buses (150-200 km) are cheaper, suitable for urban routes.

Long-range buses (250+ km) come at a higher price, ideal for intercity operations.

Operational Economics: While the initial capital expenditure is higher for electric buses, their operational costs are significantly lower—estimated at around ₹7-9/km, compared to ₹20-25/km for diesel buses. This translates into annual savings of approximately ₹3-4 lakhs per electric bus, making them a more economical choice over time.
