A heat-transfer liquid circuit for an electric vehicle propelled, at least in part, by an electric motor, the circuit including a first leg, and the first leg includes, at least, a pump, a first heat exchanger configured to exchange heat energy between the heat-transfer liquid and a refrigerant fluid, an electric-heating device, and a second heat exchanger configured to exchange heat energy between the heat transfer liquid and a flow of air dispatched towards the interior of the vehicle. The circuit also includes a second leg, and the second leg includes a third heat exchanger thermally coupled to a component of an electric drivetrain of the vehicle. The circuit further includes a third leg arranged in parallel with the first leg and connected to the latter by a member for distributing the heat-transfer liquid.
