This seems really inefficient, everyone transporting around a bunch of excess capacity? Smaller, lighter, cheaper electric cars paired with a properly built and resilient grid seems like a better goal to me.
They’d wear out roads less, use less resources to make, be safer to others in crashes, etc. I dislike the trend of increasingly larger vehicles just to move a single person around 87% of the time.
Extra "wasted" capacity has many benefits for EV battery packs.
It allows distributing load across more cells. It allows using cells with a lower C-rating, which typically have better energy density, and longer lifespan.
Distributing load reduces energy loss during charging, makes cooling less demanding, while allowing higher total charging power, which means adding more range per minute.
The excess capacity makes it easier to avoid fully changing and discharging cells. This prolongs life of NMC cells.
(but I agree that cars are an inefficient mode of transport in general)
