    Still with a view to increasing the range of an electric or hybrid vehicle, it is also sought to optimize the energy efficiency of the electrochemical generator by regulating its temperature. Indeed, the temperature has a strong influence on the operation of the electrochemical generator: the electrochemical generator must be cooled when its temperature is too high, or warmed when its temperature is too low. In particular, in winter, a low temperature of the electrochemical generator results in a very significant yield reduction so that the vehicle's autonomy can be reduced by half. In addition, when the electrochemical generator is a battery, the curves of the state of charge as a function of the charging time of the battery indicate that the charging time increases with the temperature. In addition, due to the rise in temperature during charging, the charging time is relatively fast to reach 80% of the load but is then very long to reach 100% of the load.

    [0013] Referring to FIG. 1, the device for regulating the temperature of an electrochemical generator of an electric or hybrid vehicle, comprises an air conditioning circuit of an HVAG system of the passenger compartment of the vehicle (heating-ventilation-airconditioning-cooling or heating , ventilation and air conditioning). Such HVAC systems are known to those skilled in the art and do not require here a detailed description of their construction or operation. Only the main elements are described.

A second loop comprises a second expansion orifice 12 provided upstream of an internal evaporator 14, between the external condenser / evaporator 2 and the evaporator internal 14, and said internal evaporator 14 for cooling the passenger compartment. At the internal evaporator 14 is provided a fan 16 of the air conditioning unit. The various elements are interconnected by pipes in which circulates a refrigerant, such as a refrigerant gas. The circulation in the first loop or in the second loop and the bypass is managed by means of a set of valves, the valves 18 and 20 provided at the intersection of the first and second loops and the valve 21 provided at the intersection of the first loop and the bypass 10, upstream of the first expansion orifice 8. These valves are for example solenoid valves at least 3 channels.
    According to the invention, the control device further comprises a first heating circuit of the electrochemical generator 1 in which is likely to flow the same fluid as in the air conditioning circuit. Said first heating circuit of the electrochemical generator comprises, in the fluid flow direction, a first fluid supply pipe 22 to a heat transfer element associated with the electrochemical generator 1, said first supply pipe 22 being connected to a first outlet provided between the compressor 4 and the internal condenser 6 by means of a 3-way valve 24, and a first conduit for discharging the fluid 26 from the heat transfer element, said first discharge pipe 26 being connected to a first inlet provided between the internal condenser 6 and the first expansion orifice 8 by means of a 3-way valve 28.
    According to the invention, the control device further comprises a second cooling circuit of the electrochemical generator 1 in which is likely to flow the same fluid as in the air conditioning circuit. Said second cooling circuit of the electrochemical generator 1 comprises, in the direction of circulation of the fluid, a second conduit for supplying the fluid 30 to a heat transfer element associated with the electrochemical generator 1, said second supply line 30 being connected to a second output provided between the second expansion orifice 12 and the internal evaporator 14 by means of a 3-way valve 32, and a second conduit for discharging the fluid 34 from the heat transfer element, said second discharge pipe 34 being connected at a second inlet provided downstream of the internal evaporator 14, between the internal evaporator 14 and the compressor 4, by means of the valve 20 which consists of a 4-way valve.
    Advantageously, the first supply line 22 and the second supply line 30 of the fluid to the heat transfer element of the electrochemical generator 1 are connected to said heat transfer element by a single 3-way valve 36. Similarly, , the first discharge pipe 26 and the second heat transfer medium fluid outlet pipe 34 are connected to said heat transfer element by a single 3-way valve 38. It is obvious that it is also possible to provide connections separated and independent to the heat transfer element. Furthermore, it is also possible to provide an exchanger between the valves 36, 38 and the electrochemical generator 1 to promote heat exchange.
    The valves 24, 28, 32 and 20 constitute the valves arranged to be able to put the air conditioning circuit into communication with one or the other of the first heating circuit and the second cooling circuit of the electrochemical generator 1.
    In addition, the regulating device of the invention comprises means for controlling said valves 24, 28, 32, 20, 36 and 38 arranged to allow, depending on the temperature of the electrochemical generator 1, the circulation of the fluid. of the air-conditioning circuit in the first heating circuit for heating the electrochemical generator 1 and / or the circulation of the cooling circuit fluid in the second cooling circuit for cooling the electrochemical generator 1, in order to regulate the temperature of the electrochemical generator.
    Other control means of the valves of the air conditioning circuit are provided for the operation of said valves 18, 20 and 21 for regulating the temperature of the passenger compartment, in addition to the regulation of the temperature of the electrochemical generator.
    The control means are associated with temperature sensors of the electrochemical generator 1 in order to actuate the valves according to the desired effect according to whether the vehicle is stopped or running, and according to the presence of a battery or a fuel cell, and to obtain in particular: a heating mode of the electrochemical generator, the vehicle being stopped, and in the case of the battery, the battery can be charging, a cooling mode of the electrochemical generator, the vehicle is stopped, and in the case of the battery, the battery can be charging, a heating mode of the passenger compartment and heating of the electrochemical generator, the vehicle is running, an air conditioning mode of the passenger compartment and cooling of the electrochemical generator, the vehicle being in operation, and a heating mode of the passenger compartment and cooling of the electrochemical generator, the vehicle being in operation.
    More particularly, when the vehicle is stopped, the control means of the valves, the compressor 4, and all the electronic components are arranged to operate on the sector, the vehicle being connected to the mains.
    In a first variant, the control means of the valves are arranged to render inoperative the internal condenser 6 and the internal evaporator 14 vis-à-vis the regulation of the temperature of the passenger compartment when the vehicle is at the same time. stopping, so that only the heating or cooling modes of the electrochemical generator are operational.
    In particular, when the outside temperature is cold, it is necessary to heat the battery or fuel cell to facilitate starting the vehicle, as well as heat the battery to improve the efficiency of its load. In this case of the heating mode of the electrochemical generator, the vehicle being stopped, and in the case of the battery, said battery can be in charge, according to FIG. 1, the control means of the valves are arranged so that the fluid which passes through the condenser / external evaporator 2, in contact with the cold air A, flows to the accumulator 3 via the valves 18 and 20, then in the compressor 4 where it is compressed, and thus heated, and then sent via the valve 24 into the first supply line 22 of the heating circuit of the electrochemical generator to the heat transfer element of the electrochemical generator 1 via the valve 36. during its passage, the fluid warms the heat transfer element that heats the electrochemical generator 1. Then the fluid flows in the first discharge pipe 26 of the heating circuit of the electrochemical generator via the valve 38, joins the air conditioning circuit via the valves 28 and 21 and regains the external condenser / evaporator 2 through the first expansion orifice 8. In this mode, the internal condenser 6 and the evaporator 14 are not active.
    If at startup, the electrochemical generator is too hot, or if at the time of charging, the battery is too hot, for example due to too hot outside air so the electrochemical generator must be cooled, then the control means of the valves are arranged to go into the cooling mode of the electrochemical generator, the vehicle being stopped and, in the case of the battery, said battery can be in charge, according to FIG. 2. The control means of the valves are then arranged so that the fluid flowing through the external condenser / evaporator 2, in contact with the hot air B, flows to the second supply line 30 of the electrochemical generator cooling circuit via the valve 18, the second expansion orifice 12 where it is cooled, and the valve 32, to the heat-transfer element of the battery 1 via the valve 36. During its passage, the fluid cools the coolant element which cools the electrochemical generator 1. Then the fluid flows in the second discharge pipe 34 of the cooling circuit via the valve 38, joins the air conditioning circuit via the valve 20, to pass through the accumulator 3, the compressor 4 where it is compressed the internal condenser 6 via the valve 24, said internal condenser being rendered inoperative vis-à-vis the regulation of the passenger compartment by means of a shutter 40. Then the fluid flows in the bypass 10 vi the valves 21 and 28 then returns to the external condenser / evaporator 2, without passing through the first expansion orifice 8. In this mode, the internal condenser 6 and the evaporator 14 are not active vis-à-vis the regulation the temperature of the passenger compartment.
    In a particularly advantageous manner, when the electrochemical generator is a battery, the control means of the valves are arranged to allow the circulation of the air conditioning circuit fluid in the first heating circuit to heat the battery to reach an optimal charging temperature and to allow the circulation of the air conditioning circuit fluid in the second cooling circuit to cool the battery to find the optimal charging temperature, in order to charge the battery in the shortest possible time. In this case, the control means of the valves are arranged to switch from the heating mode of the battery, the vehicle being stopped and the battery charging, according to FIG. 1, the cooling mode of the battery, the vehicle is stopped and the battery charging, according to fig. 2 and vice versa, automatically, depending on the optimum temperature of the battery to maintain to charge the battery in the shortest possible time.
    In the various cases described above, the management of the valve control means is done automatically, without human intervention.
    In another embodiment, when the vehicle is stationary, it is possible to use the thermal energy provided by the electrochemical generator to regulate the temperature of the passenger compartment. For example, it is possible to program the charging time of the battery to heat it sufficiently and take advantage of the heat released by the battery during charging to heat the cabin or to cool it sufficiently and enjoy the cold weather from the battery while charging to cool the cabin. In this case, the control means of the valves are further arranged to allow the operation of the internal condenser 6 and the internal evaporator 14 when the vehicle is stopped and regulate the temperature of the passenger compartment in addition to the temperature Of the electrochemical generator 1. Thus, for example, the temperature of the passenger compartment is comfortable when the user takes place in the vehicle to start it.
    In a preferred manner, when the vehicle is running, the control means of the valves and the compressor 4 are arranged to operate on an electrochemical generator.
    According to another variant, the control means of the valves are further arranged to allow the operation of the internal condenser 6 and the internal evaporator 14 when the vehicle is running and regulate the temperature of the passenger compartment in addition to the temperature of the electrochemical generator.
    More specifically, when the outside temperature is cold, the control means of the valves are arranged to pass the HVAC system heating mode of the passenger compartment and to allow the circulation of the air conditioning circuit fluid in the first heating circuit of the electrochemical generator for heating the passenger compartment and the electrochemical generator when the vehicle is running, as shown in FIG. 3. In this case of the heating mode of the passenger compartment and of the electrochemical generator, the control means of the valves are arranged so that the fluid which passes through the condenser / evaporator 2, in contact with the cold air A, flows towards the accumulator 3 via the valves 18 and 20, then in the compressor 4 where it is compressed, and thus heated, and then sent, via the valve 24, firstly into the first supply line 22 of the generator heating circuit electrochemically to the heat transfer element of the electrochemical generator 1 via the valve 36, and secondly in the internal condenser 6. The fan of the air conditioning unit 16 is arranged to be open so that the cold air entering C is heated by passing through the internal condenser 6 before being sent into the cabin to heat it. Then the fluid returns to the external condenser / evaporator 2 via the first expansion orifice 8. On the electrochemical generator heating circuit side, the fluid warms the heat transfer element that heats the electrochemical generator 1. Then the fluid circulates in the first discharge pipe 26 of the heating circuit of the electrochemical generator via the valve 38, joins the air conditioning circuit via the valves 28 and 21 and returns to the external condenser / evaporator 2 via the first expansion orifice 8. In this mode, the internal condenser 6 is active vis-à-vis the regulation of the temperature of the passenger compartment. In this mode, the control device can produce heat to heat the cabin on the one hand and heat the electrochemical generator on the other hand to maintain it at an optimal temperature to ensure better efficiency.
    If the electrochemical generator becomes too hot when the vehicle is running, for example due to an outside air too hot so that the electrochemical generator must be cooled, then the control means of the valves are arranged to pass the HVAC system in air conditioning mode of the passenger compartment and to allow the circulation of the air conditioning system fluid in the second cooling circuit of the electrochemical generator to cool the passenger compartment and the electrochemical generator, in accordance with FIG. 4. The control means of the valves are then arranged so that the fluid passing through the external condenser / evaporator 2, in contact with the hot air B, is directed, via the valve 18, to the second expansion orifice 12 where it is cooled, then to the valve 32 where the fluid is divided on the one hand to the second supply line 30 of the cooling circuit of the electrochemical generator to the heat transfer element of the electrochemical generator 1 via the valve 36 and on the other hand to the internal evaporator 14. The fan of the air conditioning unit 16 is arranged to be open so that the hot air entering D is cooled by passing through the internal evaporator 14 before being sent into the cabin for the cool. Then the fluid returns to the air conditioning circuit via the valve 20. On the side of the cooling circuit of the electrochemical generator 1, the fluid, after having cooled the electrochemical generator 1, flows into the second discharge pipe 34 of the cooling circuit via the valve 38, joins the air conditioning circuit via the valve 20, to cross, with the fluid from the internal evaporator 14, the accumulator 3, the compressor 4 where it is compressed, the internal condenser 6 via the valve 24, said internal condenser being rendered inoperative vis-à-vis the regulation of the passenger compartment by means of the shutter 40. Then the fluid flows in the bypass 10 via the valves 21 and 28 and then regains the external condenser / evaporator 2, without passing through the first expansion orifice 8. In this mode, the regulating device makes it possible to produce cold to cool the passenger compartment on the one hand and to cool the electrochemical generator of the other. to keep it at an optimal temperature to ensure better efficiency.
    If the electrochemical generator becomes too hot when the vehicle is running, for example due to intensive operation, so that the electrochemical generator must be cooled but the outside air is cold and the cockpit must to be heated, then the control means of the valves are arranged to pass the HVAC system heating mode of the passenger compartment and to allow the circulation of the air conditioning circuit fluid in the second cooling circuit of the electrochemical generator to heat the passenger compartment and cool the electrochemical generator, according to fig. 5. The control means of the valves are then arranged so that the fluid, which passes through the condenser / evaporator 2, in contact with the cold air A, is directed via the valve 18, on the one hand directly to the valve 20 and on the other hand to the second expansion orifice 12 where it is cooled then, via the valve 32, in the second supply line 30 of the cooling circuit of the electrochemical generator to the heat transfer element of the electrochemical generator 1 via the valve 36. The fluid, after cooling the electrochemical generator 1, flows in the second discharge line 34 of the cooling circuit via the valve 38, and joins the air conditioning circuit via the valve 20 to pass through, with the fluid coming directly the valve 18, the accumulator 3, the compressor 4 where it is compressed, and the internal condenser 6 via the valve 24. The fan of the air conditioning unit 16 is arranged to be open so that the air oid entering E is heated through the internal condenser 6 before being sent into the cabin to heat it. Then the fluid passes through the first expansion orifice 8 via the valve 21 and returns to the external condenser / evaporator 2. In this mode, the control device can produce heat to heat the cabin on the one hand and produce cold to cool the electrochemical generator on the other hand in order to maintain it at an optimum temperature to ensure better efficiency, the heat produced by the electrochemical generator being used to heat the passenger compartment.
    In these three modes of temperature control where the car is running, the management of the valve control means is done semi-automatically, the user intervening to switch the HVAC system heating mode or cabin air conditioning to adjust the temperature of the passenger compartment, the management of the temperature of the electrochemical generator being carried out automatically by means of the temperature sensors.
    The present invention also relates to a method for regulating the temperature of an electrochemical generator of an electric or hybrid vehicle, said electrochemical generator being chosen from the group comprising batteries and fuel cells, by means of a control device as defined above.
