Abstract
A system may include a first heat exchanger, a pumping device, and a valve. The pumping device may be in fluid communication with the first heat exchanger. The valve may receive a fluid from the pumping device and may be movable between a first position allowing the fluid through a first flow path and a second position to allow the fluid to flow through a second flow path. The first heat exchanger may be in heat transfer relation with an energy storage device such that heat may be extracted from the energy storage device when the valve is in the first position. Heat may be transferred from the first heat exchanger to the energy storage device when the valve is in the second position.
Claims20
A system comprising:
- a first heat exchanger;
- a pumping device in fluid communication with the first heat exchanger;
- and
- a valve receiving a fluid from the pumping device and movable between a first position allowing the fluid through a first flow path and a second position to allow the fluid to flow through a second flow path,
- wherein the first heat exchanger is in heat transfer relation with an energy storage device such that heat is extracted from the energy storage device when the valve is in the first position and heat is transferred from the first heat exchanger to the energy storage device when the valve is in the second position.
A system for controlling a temperature of a battery, the system comprising:
- a first fluid circuit including a first heat exchanger and a first compressor circulating a first fluid therethrough, the first heat exchanger being in heat transfer relation with the battery, the first fluid in the first fluid circuit is fluidly isolated from a vehicle climate control system, wherein the first fluid enters the first compressor at a first pressure and is discharged from the compressor at a second pressure that is substantially higher than the first pressure.
A system for a vehicle, the vehicle having a cabin and a battery, the system comprising:
- a first fluid path including a first heat exchanger providing a cooling effect to air within the cabin;
- and
- a second fluid path including a second heat exchanger and a valve, the second heat exchanger being in heat transfer relation with the battery, the valve being movable between a first position allowing fluid at a first temperature to flow through the second heat exchanger to extract heat from the battery and a second position allowing fluid at a second temperature to flow through the second heat exchanger to transfer heat from the fluid to the battery.
