Application: Aircraft thermal management system for an energy storage system (Patent ID: US20240069527A1)
Rolls-Royce Holdings Plc has developed a thermal management system for an energy storage system in aircraft. The system includes a pump circulating a thermal management fluid through the system and the energy storage device, with a controller circuitry adjusting the pump's capacity based on pressure or temperature readings. The pump operates at a first capacity within a set range or in response to specific conditions, and at a second capacity when power demand is absent and conditions are within the range.
The system allows for dynamic control of the pump's speed and capacity, with the controller circuitry utilizing pulse width modulated signals for precise adjustments. In case of signal loss, a constant voltage override control signal ensures the pump operates at the required capacity. Additionally, the system can be powered by a DC:DC converter supplied by the energy storage device or a generator, ensuring consistent operation. Overall, the method and system aim to efficiently manage thermal energy in aircraft energy storage systems, particularly batteries, to optimize performance and safety during various operational conditions.
