US 11,108,245 B1 · Electric battery charger system and method

Abstract

Disclosed herein is an electric battery charger system and method which may be used with electrical equipment such as an electric vehicle to improve the efficiency of operation. The charger system includes a DC motor operated by a car battery or other power source and a generator (e.g., turbine generator) to power a traction battery of the electric vehicle for recharging. In one embodiment, the charger system may have a single shaft running between the motor and generator with blades on the shaft to cool the operation of the charger system. In another embodiment, a coupler assembly is located between the motor and generator to drive the shaft of the generator. In another embodiment, the charger system may include fans having interlocking, non-contact blades which are kept apart by magnets located on the blades. A first fan is turned by the DC motor and is configured to drive a second fan which turns a shaft of the generator to create power for charging the traction battery.
