Abstract
A method for thermal management of a motor vehicle includes circulating of coolant, in a first operating state, at least in a motor cooling circuit through a series circuit that includes a motor circuit pump, an electric motor, and a low temperature (LT) radiator where the motor circuit pump is activated and where the coolant flows in a first direction through the LT radiator. The method further includes, time-shifted with respect to the first operating state, circulating of coolant, in a second operating state, at least in a chiller cooling circuit through a series circuit including a chiller, a chiller section pump, the motor circuit pump, and the LT radiator where the chiller section pump is activated, where the motor circuit pump is deactivated, where the coolant flows in a second direction through the LT radiator, and where the second direction is opposed to the first direction.
