Abstract
A thermal system for a motor vehicle has a coolant-conducting HVS circuit connected to a traction battery, a heating circuit controlling the temperature of a passenger compartment thermally coupled to the HVS circuit, a cooling circuit connected to a heat source and fluidically coupled to the HVS circuit to transfer to the traction battery heat provided by the heat source and transported by the coolant, and a control device configured to, during the heating of the traction battery, branch off at least a proportion of the heat before the transfer to the traction battery and transmit said proportion of the heat into the heating circuit to precondition the heating circuit.
