Batteries are the most expensive parts on EVs, they're heavy, require rare-earth metals and they wear out. So not an ideal solution.

Would be pretty cool to have the EV batteries on cars hooked up to the electric infrastructure and handle the offset and also charging them when there is too much power in the grid.

I always liked the idea of rapidly swappable batteries, like pulling into a gas station. Then they could be charged / stored in centralized locations which act as very large batteries for the grid. Keep batteries at 90% or even less and use that amount to absorb or push energy to the grid.

Battery recycling is a thing
