ABSTRACT:
A drive assembly comprises a DC electric motor and an integrated charger/controller/regenerator which includes a power module, a step-up module and a control circuit. The input of the power module is connected to an electric power source during charging, and to the DC motor during regenerative braking. The input of the step-up module is connected to the power module, and the output is connected to the battery. The control circuit includes a switch, and has three modes of operation: driving, regenerative braking and charging. During driving, the switch connects the battery to the power module input and the power module output to the DC motor. During regenerative braking, the switch connects the DC motor to the power module input and the power module output to the step-up module input, and the step-up module output charges the battery. During charging, the switch connects the power module output to the step-up module input, and the step-up module output charges the battery.
