Abstract
Systems and methods are provided for active cooling of a rechargeable energy storage system. A thermal conditioning system includes a cooling system configured to circulate a coolant to cool the RESS. A controller computes a generated heat amount of the RESS; computes a target temperature of the coolant based on the generated heat amount; and operates actuators of the thermal conditioning system to cool the coolant to the target temperature.
Claims20
A thermal conditioning system for a rechargeable energy storage system (RESS), the thermal conditioning system comprising:
- a cooling system configured to circulate a coolant to cool the RESS;
- and
- a controller coupled with the cooling system and configured to, by a processor:
- compute a generated heat amount of the RESS;
- compute a target temperature of the coolant based on the generated heat amount;
- and
- operate actuators of the thermal conditioning system to cool the coolant to the target temperature.
A method of thermal conditioning a rechargeable energy storage system (RESS), the method comprising:
- circulating, by a cooling system, a coolant to cool the RESS;
- calculating, by a controller, a generated heat amount of the RESS;
- calculating, by the controller, a target temperature of the coolant based on the generated heat amount and;
- operating, by the controller, actuators of the thermal conditioning system to cool the coolant to the target temperature.
A vehicle comprising:
- an electric powertrain;
- a rechargeable energy storage system (RESS) coupled with the electric powertrain;
- a thermal conditioning system including a fluid circuit that includes a coolant loop configured to circulate the coolant, including through the RESS, and including a refrigerant circuit configured to circulate a refrigerant;
- a heat exchanger through which both the coolant and refrigerant are circulated;
- and
- a controller coupled with the cooling system and configured to:
- compute a generated heat amount of the RESS;
- sum the computed generated heat amount over a time t;
- compute the target temperature of the coolant to remove the generated heat amount from the coolant during a next time that is equal to the time t;
- and
- operate actuators of the thermal conditioning system to cool the coolant through the heat exchanger to the target temperature over the time t.
