a car that runs on a battery that never needs to get charged
I think it is not possible. In terms of energy balance, the car would have rub with ground, thus it consumes energy. Besides, what you thought is ideal condition, because no efficiency is 100%, i.e. dynamo cannot convert mechanical energy into electrical energy with 100% efficiency.
