REDUNDANT POWER STRUCTURE FOR BATTERY MANAGEMENT UNIT

A system includes a low-voltage battery operational to present a low-voltage electrical power, a rechargeable energy storage system operational to present a high-voltage electrical power, and a battery management unit electrically coupled to the low-voltage battery and the rechargeable energy storage system. The battery management unit includes a control circuit operational to consume the low-voltage electrical power, a flyback transformer operational to convert the high-voltage electrical power into the low-voltage electrical power, and the rechargeable energy storage system, a first path operational to transfer the low-voltage electrical power from the low-voltage battery to the control circuit, and a second path coupled to the first path and operational to transfer the low-voltage electrical power from the flyback transformer to the control circuit.
