Methods and systems for cooling an electric energy storage device are described. In one example, a temperature set point of a cooling system is reduced before a vehicle reaches a location along a travel route where load on the electric energy storage device is expected to be greater than a threshold load. By lowering the temperature set point, it may be possible to maintain a temperature of the electric energy storage device below a threshold temperature.

Cooling method and system

A vehicle thermal management system includes a cabin thermal loop, a battery thermal loop, a parallel valve assembly, and a controller. The cabin thermal loop includes a first chiller in fluid communication with a vehicle cabin. The battery thermal loop includes a second chiller in fluid communication with a high-voltage battery. The parallel valve assembly selectively links the cabin and battery thermal loops and includes a three-way valve and a conduit system arranged with one another to selectively link the first chiller and the second chiller to deliver cooling capacity to the battery. The controller is programmed to, responsive to detection of an available amount of cabin thermal loop cooling capacity exceeding a detected passenger vehicle cabin cooling capacity request, output a command to the parallel valve assembly to release the excess cooling capacity from the cabin thermal loop to cool the HV battery.

Thermal management system for electrified vehicle

A cold ambient battery chilling mode of an electric vehicle may be implemented if the vehicle battery is being charged when the ambient air temperature is low and a temperature of the battery is elevated. During cold ambient charging, coolant flows through a heater core and through a battery heat exchanger. Cold ambient air may be utilized to cool the coolant flowing through the heater core, and coolant from the heater core flows through the battery heat exchanger and cools the battery during charging. A battery chiller may be deactivated when the cold ambient battery chilling mode is activated to reduce energy consumption.

Cold ambient battery cooling utilizing the climate cabin heating system

A vehicle thermal management system including a cabin thermal loop, a battery thermal loop, a parallel valve assembly, and a controller is provided. The cabin thermal loop may include a first chiller. The battery thermal loop may include a second chiller and a high-voltage (HV) battery. The parallel valve assembly selectively may link the thermal loops. The controller may be programmed to, responsive to detection of a high load condition, command the parallel valve assembly to link the thermal loops such that the chillers operate together to cool a vehicle cabin and the HV battery. The parallel valve assembly may include a three-way valve and a conduit system selectively connecting the chillers, the three-way valve, and the HV battery.

A thermal management system for a vehicle includes a coolant loop routed through a traction battery, a battery chiller, a power electronics device, and a radiator. The system also includes a battery bypass valve in the coolant loop configured to, in a bypass position, bypass the traction battery and the battery chiller. The system includes a controller programmed to, in response to a demand for cabin cooling being greater than a predetermined demand, operate the battery bypass valve in the bypass position.
