A system for control of an electric powertrain is provided. The powertrain includes a battery configured for providing electrical energy at a first relatively higher voltage in direct current. The powertrain further includes a power inverter including a first phase circuit, a second phase circuit including first and second switches, and a third phase circuit including third and fourth switches. The powertrain further includes a motor configured for receiving alternating current electrical energy from the power inverter. The system further includes a computerized controller operating a charging cycle. The charging cycle includes deactivating the first phase circuit of the power inverter and selectively cyclically activating the first switch, the second switch, the third switch, and the fourth switch to direct electrical energy provided at a second relatively lower voltage in direct current through the motor to provide a flow of electrical energy at the first voltage to the battery.
