Vehicle compressor system
A vehicle cooling system for cooling a vehicle battery may include a cabin cooling system having an electrical compressor arranged on a first refrigerant path and driven by a vehicle electrical system to cool a vehicle cabin, a battery cooling system having a mechanical compressor arranged on a second refrigerant path and driven by a vehicle engine, and a battery chiller in communication with both refrigerant paths and configured to cool coolant provided to a vehicle battery.
1. A vehicle cooling system for cooling a vehicle battery, comprising:
a cabin cooling system having an electrical compressor arranged on a first refrigerant path and driven by a vehicle electrical system to cool a vehicle cabin,
a battery cooling system having a mechanical compressor arranged on a second refrigerant path and driven by a vehicle engine,
the battery cooling system including a first chiller on the first refrigerant path to cool coolant provided to a vehicle battery, wherein the battery cooling system includes a second chiller arranged on the second refrigerant path and the second chiller is arranged in series with the first chiller;
a coolant loop configured to provide the coolant to the vehicle battery, at least one of the first chiller and the second chiller being in communication with the coolant loop to cool the coolant therein; and
a coolant pump arranged on the coolant loop.
2. The system of claim 1 , further comprising at least one valve arranged on the coolant loop to control the rate of coolant supplied by at least one of the first chiller or the second chiller.
3. A vehicle cooling system for cooling a vehicle battery, comprising:
a cooling system having a mechanical compressor and a battery chiller arranged on a battery refrigerant path separate from a cabin refrigerant path of a cabin cooling system, the mechanical compressor driven by a vehicle engine, and
a coolant loop configured to supply coolant to a vehicle battery from the battery chiller;
a cabin chiller in communication with both refrigerant paths and the coolant loop to cool coolant provided to a vehicle battery, wherein the cabin chiller is arranged in series with the battery chiller; and
a coolant pump arranged on the coolant loop.
4. The system of claim 3 , further comprising at least one valve arranged on the coolant loop to control the rate of coolant supplied by at least one of the battery chiller or the cabin chiller.
5. A vehicle cooling system for cooling a vehicle battery, comprising:
a cabin cooling system having an electrical compressor arranged on a first refrigerant path and driven by a vehicle electrical system to cool a vehicle cabin,
a first battery chiller arranged in parallel with the first refrigerant path, and
a coolant loop configured to supply coolant to a vehicle battery from the first chiller;
a battery cooling system having a mechanical compressor arranged on a second refrigerant path and driven by a vehicle engine, and a second chiller, wherein the first battery chiller is arranged in series with the second chiller; and
a coolant pump arranged on the coolant loop.
6. The system claim 5 , wherein both the first chiller and the second chiller are in communication with the coolant loop to cool the coolant therein.
7. The system of claim 5 , further comprising at least one valve arranged on the coolant loop to control the rate of coolant supplied by at least one of the first chiller or the second chiller.
