Patent ID: 8613305

Claim:
A motor vehicle, comprising: an electric motor; a passenger compartment; an electronic power circuit; and a cooling circuit for cooling the electronic power circuit, in which a coolant fluid circulates, and which comprises: a heat exchanger configured to carry away calories transported by the coolant fluid to outside of the vehicle; a heating radiator placed upstream of the heat exchanger, configured to transfer the calories transported by the coolant fluid to air of the passenger compartment, by a fan; an adiabatic reservoir configured to store all of the coolant fluid circulating in the cooling circuit, in compensation for which, by storing all of the fluid reheated during the operation of the vehicle, it is possible, by inserting the fluid stored in the adiabatic reservoir into the heating radiator, to rapidly heat the passenger compartment when the vehicle starts; and a secondary pump configured to transfer all of the coolant fluid into the adiabatic reservoir, wherein the adiabatic reservoir comprises an inlet directly connected to an outlet of the heating radiator and an outlet connected to an inlet of the heating radiator.
