Abstract
A control device, and a method for operating the control device, optimizes cooling of a high-voltage accumulator using an air-conditioning system in a vehicle. A coolant flow which is insufficient is detected by an evaporator for the high-voltage accumulator and, as a result, heat losses inside a condenser of the air-conditioning system are reduced for increasing the flow of the coolant.
Claims19
A method for optimizing the cooling of a high-voltage accumulator using an air-conditioning system in a vehicle, wherein the method comprises the acts of:
- identifying an excessively low refrigerant flow through an evaporator for the high-voltage accumulator;
- and
- reducing, in response to the excessively low refrigerant flow, heat losses within a condenser of the air-conditioning system in order to increase the refrigerant flow.
A control unit for a vehicle configured to optimize the cooling of a high-voltage accumulator using an air-conditioning system of the vehicle, wherein the control unit is configured to:
- receive input variables;
- identify an excessively low refrigerant flow through an evaporator for the high-voltage accumulator based on said input variable;
- and
- reduce, in response to identifying the excessively low refrigerant flow, heat losses within a condenser of the air-conditioning system in order to increase the refrigerant flow.
