Thermal management system with secondary circuit

A system, comprising:

• a primary circuit comprising a first chiller, a second chiller, and at least one indirect condenser;
• a secondary circuit comprising a first partial circuit having a cabin cooling device, a second partial circuit having a cabin heating device, a third partial circuit comprising a battery, and a fourth partial circuit comprising a heat exchange device and power electronics;
• a plurality of valves arranged in the system including a battery valve, a power electronics valve, a heat exchange device valve, an indirect condenser valve, and a chiller valve;
• and
• a controller with instructions stored on memory thereof that allow the controller to:
• select one of a plurality of operating states in response to a temperature of the battery, a temperature of the power electronics, a cabin heating request, and a cabin cooling request, wherein at least one operating state of the plurality of operating states comprise cooling the battery and the power electronics by utilizing waste heat therefrom to meet the cabin heating request.

A thermal management system of a vehicle comprising a battery operated to propel the vehicle, the thermal management system, comprising:

• a first plurality of valves comprising a first number of ports;
• a second plurality of valves less than the first number of ports, and wherein the first plurality of valves and the second plurality of valves are arranged along and configured to control coolant through four different coolant circuits;
• and
• a controller with computer readable instructions stored on non-transitory memory thereof that when executed cause the controller to:
• select an operating state of a plurality of operating states based on one or more a temperature of the battery, a temperature of power electronics, a cabin heating request, and a cabin cooling request;
• and
• actuate a position of one or more of the first plurality of valves and the second plurality of valves based on the operating state.
