  • Opposing contactors for energy storage device isolation
    Patent number: 9991714
    Abstract: An energy storage system can include an energy storage device, such as a battery energy storage device, having a first terminal and a second terminal. A first unidirectional contactor can be coupled to the first terminal. A second unidirectional contactor can be coupled to the second terminal. The first unidirectional contactor can be coupled to the energy storage device with opposite polarity relative to the second unidirectional contactor. The first unidirectional contactor and the second unidirectional contactor can be controlled based on direction of current flow associated with the energy storage device.
