Methods and systems for powering a transport refrigeration unit (TRU) via one or more batteries when not connected to shore power are disclosed. The system may include one or more batteries configured to supply a DC battery voltage, an inverter/charger coupled to the one or more batteries and configured to convert the DC battery voltage to an AC output voltage for powering an electric motor coupled to a compressor of the TRU, and an electrical vehicle (EV) charging port coupled to one or more of the one or more batteries and the inverter/charger, the EV charging port configured to receive a charging voltage from an EV charger. In addition, methods and systems for providing supplemental power to a vehicle battery system are disclosed. The system may include one or more batteries and a DC/DC converter coupled to the one or more batteries and the vehicle battery system.
