Onboard generator drive system for electric vehicles
Abstract:
An electric vehicle utilizes an internal combustion engine to drive the vehicle's main electric drive system in the regeneration mode and to charge the battery when the vehicle is stopped. The electric vehicle's main drive controller and motor are used as the generator to recharge the battery when the vehicle is stopped via a clutch mechanism allowing the motor to act as a generator while the vehicle is at rest. As the vehicle proceeds throughout the drive cycle, the vehicle is powered by the electric motor from the battery. The battery is recharged to a specified state of charge when the vehicle is parked. The internal combustion engine only operates to charge the battery, and the electric motor is used to propel the vehicle.
