Abstract
An electric vehicle can include 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.
Claims20
A vehicle comprising
- a first drive system configured to drive a first wheel of the vehicle, wherein the first drive system comprises a battery powering an electric motor;
- a second drive system configured to drive a second wheel of the vehicle, wherein the second drive system is powered by a non-battery power source,
- wherein the first wheel is coupled to a first axle, wherein the second wheel is coupled to a second axle, wherein the first axle is different from the second axle;
- a controller operatable by a driver of the vehicle,
- wherein the controller is configured to provide a first mode of operation,
- wherein in the first mode of operation, the first drive system drives the first wheel and the second drive system is excluded from driving the second wheel,
- wherein the controller is configured to provide a second mode of operation,
- wherein in the second mode of operation, the second drive system drives the second wheel and the first drive system is excluded from driving the first wheel,
- wherein the controller is configured to provide a third mode of operation,
- wherein in the third mode of operation, the first drive system drives the first wheel and the second drive system assists the first drive system by simultaneously driving the second wheel during an acceleration of the vehicle,
- wherein in the acceleration, the first and second drive systems are cooperated to preserve or to prevent a reduction of a battery range of the vehicle.
