On the electric cars that would be the way to go. I am convinced that you can put more power into the battery than you can take out of it. By using alternators, notice I said more than one. You can recharge the battery as you drive down the road. Think of the big truck, I know, I drove one over the road for 26 years. One alternator charges the lights, fan, bunk, TV, radio, and everything else you may have to pass time inside the truck. If one alternator can do all that. Why can't we recharge the battery in a car while going down the road, and keep it recharged. That would eliminate having to stop and recharge or change batteries. No need for gas, because it runs off electric. Problem solved, it is that simple. Thank you for the comments on this at Quentinhardin197@aol.com.
