Abstract

A heating system for an electric or hybrid vehicle is provided. The heating system includes a refrigerant circuit, a heater heat exchanger which is arranged in a heating circuit, for air-conditioning the interior, a high-voltage storage device which is arranged in an HVS circuit, and a cooler which is arranged in a cooling circuit. The heating circuit, the HVS circuit, and the cooling circuit are integrated into a common coolant circuit. In a first HVS cooling operation, the HVS circuit is separated from the cooling circuit and connected to a chiller in order to discharge heat into the refrigerant circuit. In a second HVS cooling operation, the HVS circuit is connected to the cooling circuit via a chiller bypass in order to discharge heat via the cooler.
