While a 90% efficient motor is quite good, a 90% controller and a 90% charger is not. I would expect them to be closer to 95%. But I have to back down from easy, according to [1], some Tesla owners charge their vehicles at 80% efficiency and not the ideal 92-98%. I imagined that would be a problem at those energy levels, apparently not! Anyhow, there is nothing inherently worse about fueling a central ICE to pump out electricity to EVs than directly fueling an ICE car. Larger ICEs tend to be more efficient, especially so for diesels. If you add the savings by the regenerative charging enabled by electric motors, it becomes even more favorable to electrify cars. We need a lot of batteries though! [1] https://forums.tesla.com/forum/forums/charging-efficiency-0 https://forums.tesla.com/forum/forums/charging-efficiency-0
