Abstract: Embodiments of the present invention provide improved fault detection and mitigation systems, methods, and techniques used in a BMS in an energy storage system (for example, grid energy storage). Embodiments of the present invention may detect battery malfunction in a battery stack and take quick corrective and preventative measures accordingly. Embodiments of the present invention may also provide select redundant components to implement safety techniques described herein.

Abstract: A switching circuit can help reduce electrical feedback ringing at a gate terminal of a transistor. The switching circuit can include a transistor circuit to switch an electrical signal and a control circuit to provide an actuation signal to the gate terminal of the transistor device. The switching circuit can also include a booster circuit that is disposed between the control circuit and the gate terminal of the transistor device. The booster circuit can be configured to detect a signal from the control circuit to turn off the transistor device and, responsive to the detected signal, drive a current into the gate terminal of the transistor device for a specified span of time before the transistor device turns off.

Abstract: Power systems having a DC content, such as photovoltaic (solar) panels present a problem if an arc fault appears because of a small break in a cable. The present disclosure describes an arc fault detection system that captures data in segments, examines the frequency spectrum to remove ‘false arc’ signatures and interference from a power converter of the power system, and then examines the cleaned frequency spectrum for arc events.
