I just bought 8kw of LiFePO4 batteries and have been testing them to see how rapidly I can charge them without raising their cell temperature too high. I paralleled three variable supplies and tested them all the way to 160amps but they became quite hot at the higher currents.

The holy grail would be a breakthrough in super-capacitor design. If we could replace EV batteries with capacitors you could charge them in moments.... but the inrush current levels would be astronomical. We don’t have a grid strong enough for that yet.

Linears or switchers?..................

Short one of those and it’s a bomb.

Research capacitors instead of batteries for EV. I was if the same thought and found out they will not directly replace batteries. What may work is a capacitor for the take off from a stop light and then use regen to recharge capacitor. Maybe best of both worlds, fast discharge and recharge for high flow needs and batteries for range with low flow rates.
