  • Patent number: 5406126
    Abstract: A hybrid motor vehicle includes a storage battery providing motive power to an electric motor under the control of a microprocessor. A generator with an internal combustion engine may be used to charge the storage battery. The motor is operated either in an actuated mode in which current flows from the battery and a dynamic braking mode in which regenerated current flows from the motor to the battery. Electronic circuitry is used to insure that regenerative current is generated even if the motor Em.sub.f is lower than the voltage of the storage battery.

  • Patent number: 5283470
    Abstract: A motor vehicle drive system includes a brushless motor driven by a battery and directly coupled to the vehicle wheels for providing primary motive power. During braking, the motor acts as a generator for recharging the battery. Preferably the recharging current is first allowed to build up by shunting the motor so that the regeneration may occur at both high and low speeds. The regenerative current period may be varied with the speed of the vehicle.
