Overview:
Electric Vehicles are a key part of our tomorrow and how we get there. If we can get all the fossil fuel vehicles off our roads, out of our seas and out of our skies, we'll have a much better environment. This community is where we discuss the various different vehicles and news stories regarding electric transportation.

Short version; lithium cells operate on a sort of continuum between power density and peak discharge rate. Individual cells are usually built to drain only as fast as is needed to maximize how much total power they can hold.
The batteries for phones usually just have a single lithium cell, maybe up to three or four for some laptops, but the load of an electric car's motors and electronics is spread among hundreds of cells. The relatively slow charge/discharge rate needed per cell makes for a slower rate of degredation overall compared to what you're used to.
That's very concisely and neatly explained, thank you.
