POWER MANAGEMENT FOR AN ELECTRIC DRIVE SYSTEM Abstract A power system for an electric vehicle is provided. An electric motor (20) is arranged to provide driving mechanical output for moving the vehicle. An electric generator (80) is arranged to convert mechanical energy, due to movement of the vehicle, into electrical energy. The system includes a first and a second rechargeable electrical power storage device (50, 60), which are electrically isolated from one another. A controller (10) is arranged to selectively connect one of the first and second rechargeable electrical power storage device (50, 60) with the electric motor (20) in order to power the motor (20), and selectively connect the other of the first and second electrical power storage device (50, 60) with the generator (80) to receive charging. |
