    EV owner. Upcycled battery pack for 50% better range in winter.
    However, EVs not as green as some suggest. Tesla model 3 and VW Golf similar emissions to build and deliver. Smaller vehicles less weight, smaller tyres less PM10 roadside emissions. 2/3 of latter are not from exhausts. Higher weight for given range and higher torque means driven tyres wear out similar to performance ice.
    BMW i3 pack around 250kg. Tesla model S around 750kg.
    Batteries like petroleum don't come without environmental impact.
    Recycling of lead acid batteries around 95%. Lithium packs much more energy intensive.
    8 year pack warranty is not 100% capacity but a buffer gets reduced with each service to get 80% (some are less generous). So if under that in final year of warranty, a few new cells can be installed to get back to 80%, not whole pack replacement!
    Rapid Charging speed depends on pack size, SOC, temperature and degradation. It's not high amps throughout. Most manufacturers recommended 40 to 70% SOC to ensure long life. More rapid cycles more degradation. Likewise V2G.

    2:38, isn't using petroleum directly in cars much better than using coal in power plants and then transmitting that power?

      Hello, thank you for your question. Please see our link at the end of the video (theicct.org/cards/stack/explaining-electric-vehicles) for a more detailed analysis on this point, which is a very good one to mention.

    3:03 you can see EVs break with ICE cars only at 50k miles or 81k kilometres. Don't need to say more. Expensive toys for the wealthy, subsidised to death by the tax payer. In the UK, you see a lot of businesses now buying Taycans to write off the £100k purchase price from their profits and save corporate tax. Besides, wait until they are taxed properly for driven miles, which will come inevitably in a couple of years. Then your fuel price will jump significantly in comparison to the cheap household electricity prices mostly used in this type of calculations. On a public charger, there is hardly an advantage over petrol already today, in some cases electricity is more expensive per mile. Overall, electric cars aren't cheap. If you can afford it, like it etc. good for you, but stop selling them as cheap.
