Abstract

Methods, systems, and apparatus for an electric vehicle. The system includes a battery control unit configured to be in a grid-connected mode or a stand-alone mode. The system includes a shared boost converter connected to a battery. The shared boost converter receives alternating current (AC) power, steps up voltage and converts the AC power to direct current (DC) power when the battery control unit is in the grid-connected mode. The shared boost converter receives DC power from the battery and steps up voltage when the battery control unit is in the stand-alone mode. The system also includes an inverter configured to receive the stepped up DC power when the battery control unit is in the stand-alone mode and convert the DC power to AC power. The system also includes a motor/generator connected to the inverter and configured to receive AC power for powering a drivetrain of the electric vehicle.
