90% efficiency driving the wheels, the loses are heat and comfort systems. 90% efficiency charging the battery, the loses are the cooling system. 90% efficiency delivering power, the loses are in the grid and the transformers and DC converters and the long charging cord.
So, 0.9 ** 3 == maximum 72.9% efficient just on a basic level. It's worse if the weather or wind are against you, both in driving, and in battery cooling management.
The only advantage these things have is they can charge with cheap power and drive during the day. However, since they decided to throw away NG and Nuclear and put in Solar everywhere, there is no cheap and reliable off peak power anymore to handle the demand.
