  • Portable bi-directional multiport AC/DC charging cable system
    Patent number: 9630513
    Abstract: A portable, bi-directional multiport AC/DC charging cable system provides bi-directional power flow to and from one or more energy storage cells of a vehicle. The system includes a direct current (DC) input/output cable configured to be coupled to the vehicle and an alternating current (AC) input cable configured to be coupled to an AC power source. The system further includes a power module that is coupled to each of the DC input/output cable and to the AC input cable. The power module has an AC output for providing AC power to an external AC load, and a bi-directional AC/DC converter configured to galvanically isolate the vehicle from each of the AC power source and external AC load.
