Ok, here's a crazy idea, probably not suitable for a commercially made vehicle (or any vehicle
).
But how about a low loss capacitive setup where the batteries charge up some capacitors and then the capacitors return the charge to the batteries. Not talking about the whole battery charge just a tiny portion. Like a mini charge and discharge cycle. Repeat the cycle over and over and the batteries would get heated and if losses could be minimised then maybe it would use less power overall compared to having the car on idle for a prolonged time.
In each cycle there would be heat generated in the batteries on both the charge and discharge portion of the cycle.
Maybe even have it integrated into the controller and use the controllers capacitors and ability to feed regen back to the batteries?
