CONTROL SYSTEM FOR THERMAL MANAGEMENT AND DISTRIBUTION

DRIVE March 14, 2024

A cabin heating circuit includes a first pump, a heat source, and a heater core. A battery heating circuit includes a first flow path that branches off from the cabin heating circuit at a three-way flow control valve. The battery heating circuit further includes a second flow path that is independent of the first flow path. The first flow path and the second flow path are thermally coupled by a heat exchanger. The second flow path includes the heat exchanger, a second pump, and a battery heat exchanger. The control unit adjusts an output of the heat source, an opening degree of the three-way flow control valve, an output of the first pump, and an output of the second pump. If a cabin and a battery are heated simultaneously, the control unit regulates the output of the first pump and/or the output of the second pump.
