Abstract:
1. A method of charging a battery of an electric vehicle, the electric vehicle including a generator driven by an engine and an electric motor driven by the battery, the electric motor being configured to drive a drive axle of the electric vehicle to move the electric vehicle, the method including: providing a regenerative braking system with the electric vehicle, the regenerative braking system being configured to transfer kinetic energy of the electric vehicle to the electric motor to rotate the electric motor; rotating the electric motor with electrical power from the battery to move the electric vehicle; generating a first electrical current with the generator, the first electrical current being routed to the battery; rotating the electric motor with the regenerative braking system to slow movement of the electric vehicle and to generate a second electrical current, the second electrical current being routed to the battery; charging the battery with the first and second electrical currents; monitoring the first and second electrical currents during the charging step to determine a total electrical current supplied to the battery; and removing the first electrical current from the battery upon the total electrical current exceeding a first predetermined threshold.
