I feel there is also a room for mobile superchargers. They can come to your house and fully charge your car in half an hour, rather than waiting for hours on home voltage.
Once we have supercapacitors and room temperature superconductors, a lot of these problems go away, though.
Exciting times!
There are a few problems with the swapping idea:
- People like to have ownership over their batteries (and the battery capacity)
- Logistics around swapping availability and costs
But the biggest one is:
- Charging continues to get faster and capacity continues to increase.
Whatever small amount of time is currently saved by swapping will be irrelevant by the time anyone could overcome the current obstacles to get something off the ground - it's a bad strategic bet.
