Abstract
The present invention discloses electric vehicles and methods to operate such vehicles, comprising an electric drive capable of moving the vehicles, together with a non-battery operative feature to enhance the performance of the vehicle, such as extending the range or increasing the power. The non-electrical enhanced feature is independent and not integrated with the electric drive, to enable the return of the vehicle design to pure electrical power with minimum modification.
