Abstract
Method for heating a coolant of an electrical traction machine of a motor vehicle, the electrical machine including, in addition to the coolant, a stator including a polyphase winding, the stator being in heat exchange with the coolant, a rotor, and an inverter/rectifier supplying power to the polyphase winding. The inverter/rectifier includes a plurality of switching cells controlled by a control device. The control device of the inverter/rectifier is configured to control the switching cells so as to short-circuit the polyphase winding in predetermined conditions for the purpose of heating the coolant.
