Abstract
An electrified powertrain includes an electric motor having four or more coils corresponding to four or more AC phases and configured to generate drive torque to propel an electrified vehicle. The electrified powertrain also includes a low voltage electrical system comprising independent battery modules each configured to output a separate low DC voltage, and a power inverter module (PIM) configured to receive each of the separate low DC voltages from the battery modules, generate a separate low AC voltage for each AC phase using all of or fewer than all of the separate low DC voltages, and output the separate low AC voltages to the coils of the electric motor to drive the electric motor to generate the drive torque to propel the electrified vehicle, wherein none of the separate low DC voltages are electrically isolated and none of the separate AC voltages are considered high voltage.
