1. A motor vehicle, comprising: an electric motor;a passenger compartment;an electronic power circuit; anda 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; anda 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. 2. The motor vehicle as claimed in claim 1, wherein the reservoir is placed above the cooling circuit so that the stored fluid flows into the cooling circuit under effect of gravity. 3. The vehicle as claimed in claim 1, further comprising a valve-forming means connected to the outlet of the adiabatic reservoir and configured to cut off circulation of the fluid to the heat exchanger. 4. The vehicle as claimed in claim 1, wherein the cooling circuit also makes it possible to cool the motor. 5. The vehicle as claimed in claim 4, wherein the cooling circuit further comprises complementary valve-forming means placed to allow cutting off or reduction of flow of the coolant fluid in a portion of the cooling circuit used for cooling of the motor. 6. The vehicle as claimed in claim 1, further comprising a computer configured to drive a temperature sensor configured to measure a temperature of the coolant fluid stored in the adiabatic reservoir, and the computer is configured to drive an external temperature sensor configured to measure the external temperature. 7. The vehicle as claimed in claim 1, wherein the electronic power circuit, the electric motor, and the heating radiator are connected in parallel.
