You touched on regenerative breaks, but what about for EV’s with power management? Will we see longer ranges on the same platform due to needing less power from the battery or is that going to require a full redesign
You certainly would see longer ranges for the same battery if you just swapped the cabling and motor over to superconducting versions, but there are kind of two scenarios at play here.
You have highway driving where a lot of your losses are mechanical due to high sustained speeds (air resistance and friction). Those wouldn't go away, but your "electrical to mechanical" losses would be reduced, so you'd see modest improvements.
Then you have around town driving where your losses from accelerating and decelerating are much larger than the mechanical losses (air resistance and friction). Here with proper design changes I think you would see spectacular improvements in efficiency.
Unfortunately, this doesn't help much with the EV 'range anxiety' issue haha. Go figure.
I don’t have range anxiety lol. I think once most people get in an EV they would realize the anxiety isn’t needed. But seeing the boosts to range does help with that anxiety. I’ve been watching this and the solid state battery tech for a bit now. I’m not an expert in either but I feel like with solid state batteries finally hitting the market and now this, driving could be revolutionized in less than 10 years
