Performance is excellent. And, because the systems are all electric, the air conditioners and accessories can be operated by timers and over short periods of time when the vehicle is not being driven. Refueling is extremely convenient. You park in your garage, take 10 secs. Cost of operation is about the same as an internal combustion engine.
Electricity is extremely cheap.
If you considered only electricity, the car would operate for far less than a comparable gasoline powered vehicle. However, just like the batteries that start gasoline engines, the batteries in the electric car get old and must be replaced. The cost of batteries over time, combined with the cost of electricity, is very similar to the cost of burning gasoline. At the same time, costs for other types of maintenance are very low. Electric motors are very reliable as are the electronics that run them.
