Solid-state battery management system for high current applications

A battery management system (BMS) printed circuit board assembly (PCBA) for managing a battery comprising:

• a plurality of solid-state power transistors in back-to-back serial configuration configured to connect and disconnect the battery, and to function as resettable fuse,
• a plurality of energy clamping circuits connected in parallel to the plurality of solid-state power transistors, the plurality of energy clamping circuits configured to provide an alternative current path when the plurality of solid-state power transistors are turned off,
• a gate clamping circuit across a drain and gate of the plurality of solid-state power transistors, the gate clamping circuit configured to inject gate current to partially keep the plurality of solid-state power transistors in an active region and slow down the turn-off of the plurality of solid-state power transistors when a voltage across the plurality of solid-state power transistors and the plurality of energy clamping circuits exceeds a breakdown voltage of the gate clamping circuit,
• gate drive circuitries configured to turn on and off the solid-state power transistors,
• one or more shunt resistors configured for current sensing,
• a battery monitoring application-specific integrated circuit (ASIC), and
• a microprocessor,
• wherein the battery monitoring ASIC and the microprocessor are configured to provide redundant overcurrent detection.
