A vehicle includes a cooling arrangement that includes an air conditioning loop and a battery cooling loop connected together by a common chiller and arranged to cool each of cabin air and a battery. A coolant three-way proportional control valve is connected to the chiller and the battery. The control valve is configured to operatively control a capacity of the chiller for the battery.

Vehicle cabin air conditioning and battery cooling system

A battery thermal management system includes a passenger cabin air-conditioning refrigerant loop including at least one evaporator in fluid communication with a chiller and a battery pack coolant loop in fluid communication with the chiller. A controller is configured to determine whether a temperature of the at least one evaporator falls within a predetermined temperature range, and if so to cause a valve to bypass a refrigerant from the air-conditioning refrigerant loop to the chiller. Evaporator temperature is determined by providing at least one evaporator temperature sensor.

Electric vehicle battery cooling using excess cabin air conditioning capacity

A climate-control system for a vehicle includes a refrigerant subsystem having a chiller and an electronic expansion valve (EXV) arranged to selectively route refrigerant to the chiller. The vehicle further includes a coolant subsystem having conduit arranged to circulate coolant through a traction battery and the chiller. The coolant subsystem further includes a first temperature sensor configured to measure coolant circulating into an inlet side of the chiller and a second temperature sensor configured to measure coolant circulating out of an outlet side of the chiller. A vehicle controller is configured to, in response to the battery exceeding a threshold temperature and cabin air conditioning being requested, command opening of the EXV to a predetermined position and adjust the position based on a measured coolant temperature difference between the first temperature sensor and the second temperature sensor.

Battery chiller control with electronic expansion device

A battery thermal management system according to an exemplary aspect of the present disclosure includes, among other things, a battery pack, a coolant subsystem including a chiller configured to cool the battery pack, and a refrigerant subsystem including at least one evaporator. The coolant subsystem is arranged to exchange heat with the refrigerant subsystem within the chiller. A tap line extends from the at least one evaporator to the chiller.

Battery thermal management system

A rotary valve provides single point flow control of coolant within the cooling system of an internal combustion engine. The valve distributes coolant flow from the engine in predetermined flow modes to either 1) the radiator and heater simultaneously, 2) a bypass circuit only, 3) the heater only, or 4) the radiator and bypass simultaneously. The single-point coolant control results in advantages of shorter warm-up times, a lower pressure drop (reducing power consumption by the pump), reduced engine emissions and fuel consumption, improved cabin heater performance, and improved engine durability due to reduced thermal shocks to the engine components by virtue of more precise control of engine operating temperature.
