    [0001] FIELD OF THE INVENTION The invention relates to a device for regulating the temperature of an electric storage battery. boarded a motor vehicle. TECHNICAL BACKGROUND OF THE INVENTION The invention relates more particularly to a device for the thermal regulation of an electric accumulator battery 15 on board a motor vehicle, the thermal regulation device comprising: an air conditioning circuit of the vehicle automobile in which circulates a first heat transfer fluid called "air conditioning fluid", the air conditioning circuit having at least one evaporator which allows to directly transfer the heat emitted by the battery to the air conditioning fluid, a compressor for raising the pressure and the temperature of the air conditioning fluid; a cooling circuit in which a second heat transfer fluid called "cooling fluid" circulates, the cooling circuit comprising at least a first heat source capable of heating the cooling fluid, and at least one main radiator for cooling the fluid; cooling which is likely to be short-circuited; A motor vehicle of electric or hybrid type is moved, at least in part, by an electric traction motor which is supplied with electricity by a traction battery. The performance of the traction battery is likely to vary greatly depending on its temperature. When the battery is subjected to very cold temperatures, for example negative, it loses its energy capacity. 5 A fast charge of the battery can then be prohibited. It is therefore necessary to warm the battery before recharging. Similarly, the use of the battery produces heat. When the battery is already overheated, either because of a high ambient temperature, or because of alternating too fast discharges and refills, it may be necessary to prohibit the use of the battery to preserve the cells. This generally implies that the vehicle is immobilized while the battery is cooling down to an acceptable operating temperature. To solve these problems, it is known to equip the vehicle with a thermal regulation device of the battery in order to maintain the battery cells in a range of optimal operating temperatures.
    [0002] It has been proposed to equip the battery with a coolant circuit that allows, as needed, to cool or reheat. Thus, in the application DE-A1-10 2007 004 979, the heat transfer fluid circulates in an air conditioning circuit of the vehicle.
    [0003] In this way, the battery is cooled parallel to the vehicle's space. In addition, the electrical management of the battery is supported by an electronic control unit which emits a strong heat during its operation. To prevent degradation of the electronic components of this unit, it is cooled by a cooling circuit separate from the air conditioning circuit. A main radiator dissipates the heat emitted by the electronic control unit.
    [0004] In order to make it possible to heat the battery, it is known to use the heat generated by the electronic control unit. For this purpose, a heat exchanger makes it possible to transfer the heat transported by the cooling fluid 5 to the air conditioning fluid circulating in the air conditioning circuit. To improve the heating capacity of the battery, the cooling circuit is equipped with a pipe that is likely to short-circuit the main radiator when the battery needs to be reheated.
    [0005] Such a device according to DE-A1-10 2007 004 979 nevertheless has many disadvantages. Thus, the arrangement of the heat exchanger to allow the air conditioning fluid to be heated before the battery can be heated, leads to an additional cost in the manufacture of the thermal regulation device.
    [0006] In addition, the heat emitted by the electronic control unit is not fully transmitted to the battery because part of the heat is lost in the heat exchanger. This device is not totally effective. In addition, the device according to the state of the art does not allow to quickly warm up the battery during a cold start of the vehicle. Indeed, the electronic control unit begins to heat only after a certain time of use. During this time, no hot source is available to warm the battery. It is therefore necessary to use the use of immersion heaters which are very energy intensive. BRIEF SUMMARY OF THE INVENTION The invention proposes a device for regulating the temperature of the type described above, characterized in that the cooling circuit comprises a second secondary radiator called "battery radiator" which allows the heat to be transferred directly to the heat. transported by the hot coolant to the battery when the main radiator of the cooling circuit is short-circuited. According to other features of the invention: the cooling circuit comprises a second heat source which is formed by a heat exchanger which is arranged directly upstream of the battery radiator and which makes it possible to transfer the heat of the fluid from the cooling directly to the cooling fluid, the heat exchanger 10 being arranged directly downstream of the compressor in the air conditioning circuit; the air-conditioning circuit comprises: a modulation line which is arranged in such a manner as to short-circuit the evaporators downstream of the condenser and upstream of the compressor by controlling a modulating valve when the air-conditioning circuit is operating according to a so-called "heat pump" mode; and a regulator which is arranged in a bypass between the heat exchanger and a condenser, a bypass valve 20 making it possible to control the passage of the air conditioning fluid in the expander in the "heat pump" mode of the air conditioning circuit; the cooling circuit comprises a cold start pipe whose first end is connected bypass between the battery radiator and the first heat source and a second end of which is arranged upstream of the heat exchanger, a pump being arranged in the branch comprising the battery radiator, and a cold start valve allowing, in a first cold start position, to rotate the cooling fluid in a loop by simultaneously shorting the first source of heat and the main radiator; The cold start valve can be controlled in a second heating position when the first heat source is sufficiently hot and in which the cooling fluid is looped through the first heat source and then by the second heat source before reaching the battery, the cold start pipe 60 being closed; the cold start valve is capable of being controlled in a third position in which the battery radiator is short-circuited, the cooling circuit comprising a second pump for allowing the circulation of the cooling fluid between the first source of heat and the main radiator; the cooling circuit comprises thermo15 divers which are controlled to heat the cooling fluid when the two heat sources are not hot enough; the part of the heat exchanger through which the cooling fluid passes through forms a condenser; The first source of heat is formed by an electronic control unit which manages the electric charge of the battery. BRIEF DESCRIPTION OF THE FIGURES Other features and advantages of the invention will become apparent upon reading the following detailed description for the understanding of which reference will be made to the accompanying drawings, in which: FIG. which represents a thermal regulation device of a battery made according to the teachings of the invention, the device operating in a state of cooling of the battery; FIG. 2 is a diagram similar to that of FIG. 1, which represents the thermal regulation device operating according to a first state of heating the battery when the electronic control unit is already hot; - Figure 3 is a diagram similar to that of Figure 1 which shows the thermal control device operating in a second state of reheating of the battery in case of cold start.
    [0007] DETAILED DESCRIPTION OF THE FIGURES In the remainder of the description, elements having identical structure or similar functions will be designated by the same reference.
    [0008] In the remainder of the description, the terms "upstream" and "downstream" will be used depending on the direction of flow of the heat transfer fluids in their respective circuits. FIG. 1 shows a battery 10 of electric accumulators which is on board a motor vehicle. This is for example a traction battery 10 which powers an electric traction motor of the vehicle. During the operation of the vehicle, the temperature of the battery 10 is regulated by a thermal regulation device 12 which is on board the vehicle. The battery temperature is controlled so as to be maintained within an optimum operating temperature range. The thermal regulation device 12 comprises mainly: a circuit 14 for conditioning the vehicle in which a first heat transfer fluid called "air conditioning fluid" circulates; and a cooling circuit 16 in which a second heat transfer fluid called "cooling fluid" circulates.
    [0009] These two circuits 14 and 16 are sealed with respect to each other, that is to say that the cooling fluid and the cooling fluid are not mixed. The air conditioning fluid is intended to change phase 5 circulating in the air conditioning circuit 14, as will be explained in more detail later. This is for example freon. The air conditioning circuit 14, shown at the top of the figures, comprises a first evaporator 18 which passes through the battery 10. The first evaporator 18 makes it possible to directly transfer the heat emitted by the battery 10 to the cold air conditioning fluid. For this reason, this first evaporator 18 will be referred to hereafter as "battery evaporator 18". This battery evaporator 18 is intended to cool the battery 10 when its temperature exceeds a determined upper threshold. The air conditioning circuit 14 is also intended to cool a passenger compartment of the vehicle. For this purpose, the air conditioning circuit 14 also comprises a second evaporator 20 which is arranged parallel to the battery evaporator 18. The second evaporator 20, called "cabin evaporator 20", is arranged in a ventilation duct (not shown) of the passenger compartment to cool the air. In each of the evaporators 18, 20, the cooling fluid passes from the liquid phase to the gas phase by evaporation. This causes heat absorption by the cooling fluid. The two evaporators 18, 20 are connected in parallel to a common compressor 22 which is arranged downstream via a common pipe 24. The compressor 22 is for compressing the gaseous air conditioning fluid. This results in an increase in the temperature and pressure of the air conditioning fluid.
    [0010] The compressor 22 supplies a downstream condenser 26 via a pipe 28. In the condenser 26, the cooling fluid passes from the gaseous phase to the liquid phase by condensation. This causes heat loss of the air conditioning fluid. The condenser 26 then supplies each of the evaporators 18, 20 with cooling fluid via a controlled modulation valve. Upstream of each evaporator 18, 20, and downstream of the modulating valve 30, there is arranged an associated expander 32, 34 for reducing the pressure, and thus the temperature, of the liquid air conditioning fluid before reaching the evaporator 18, 20 associated. The air conditioning circuit 14 is also capable of operating in a "heat pump" mode. For this purpose, the air conditioning circuit 14 comprises a modulation duct 36 which is arranged in such a way as to short-circuit the evaporators 18, 20 directly downstream of the condenser 26. The modulation duct 36 thus conducts the air conditioning fluid 20 condenser 26 directly to the compressor 22. The passage of the air conditioning fluid in the modulation conduit 36 is controlled by a valve. This is the modulation valve 30. The modulation valve 30 is thus capable of being controlled in at least two positions: a first so-called "air-conditioning" position in which the air-conditioning fluid circulates towards the evaporators 18, 20 while the modulation conduit 36 is closed ; and a second so-called "heat pump" position in which the air conditioning fluid flows directly to the compressor 22 via the modulating conduit 36, the evaporators 18, 20 being no longer supplied with cooling fluid.
    [0011] In addition, a heat exchanger 38 is interposed in the pipe 28 which leads from the compressor 22 to the condenser 26. The heat exchanger 38 is thus arranged directly downstream of the compressor 22 so as to be traversed by the hot gaseous air conditioning fluid. As will be explained later, the heat exchanger 38 makes it possible to transfer the heat transported by the cooling fluid to the cooling fluid. The structure and function of this heat exchanger 38 will be described in detail later. In the embodiment shown in the figures, the part of the heat exchanger 38 through which the cooling fluid passes through forms a condenser 39. A pressure regulator 40 which is arranged in parallel with respect to the pipe section 28 situated between the heat exchanger 38 and the condenser 26. A bypass valve 42 is controlled between: a first so-called "direct" position, in which the air-conditioning fluid circulates directly in the pipe 28 without forcing the passage through the expander 40 in a normal operating mode of the air conditioning circuit 14 said "air conditioning mode"; and a second so-called "expansion" position in which the circulation of the air-conditioning fluid is diverted towards the expander 40 in the "heat pump" mode of the air-conditioning circuit 14. The cooling circuit 16, which is shown below in the figures, is now described in detail. In this cooling circuit 16, the cooling fluid is intended to remain in the liquid phase. This is for example a mixture of water and antifreeze. The cooling circuit 16 has a first heat source 44 which is capable of heating the cooling fluid. The first source 44 of heat is here formed by an electronic control unit 44 whose function is to manage the electrical charge of the battery 10. Such an electronic control unit 44 is known to release a strong heat during its operation. . However, its electronic components are likely to be degraded if the temperature is too high. The cooling circuit 16 thus makes it possible to lower the temperature of the electronic control unit 44 by allowing the cold cooling fluid to absorb the heat emitted via a heat exchange surface 10 (not shown ). The cooling fluid thus heated by the electronic control unit 44 is conveyed to a radiator 46 main coolant cooling. The coolant is circulated by means of a first pump 48 which is here arranged downstream of the main radiator 46 and upstream of the electronic control unit 44. The cooling circuit 16 also comprises a heating pipe 50 which makes it possible to short-circuit the main radiator 46. This heating pipe 50 is connected downstream of the electronic control unit 44 and upstream of the first pump 48. A heating valve 52 is controlled selectively between: a first cooling position in which the cooling fluid passes by the main radiator 46 by closing the passage in the heating pipe 50; and a second heating position in which the main radiator 46 is short-circuited. The cooling circuit 16 comprises a second secondary radiator 54, called a "battery radiator 54", which makes it possible to directly transfer the heat transported by the second hot cooling fluid to the battery 10 by conduction when the main radiator 46 of the cooling circuit 16 is short-circuited.
    [0012] The battery heater 54 is arranged in a pipe section 56 arranged downstream of the first pump 48 and upstream of the electronic control unit 44. This section 56 will subsequently be designated "heating section 56". The cooling circuit 16 includes a second heat source which is formed by the heat exchanger 38 which is arranged in the heating section 56 directly upstream of the radiator. 54 of the battery and downstream of the first pump 48. The heat exchanger 38 transfers the heat of the air conditioning fluid directly to the coolant when the air conditioning circuit 14 operates in "heat pump" mode. The cooling circuit 16 also includes immersion heaters 58 which are arranged in the heating section 56 between the heat exchanger 38 and the battery heater 54. The immersion heaters 58 are controlled to heat the cooling fluid when the temperature of the battery 10 is below a determined lower threshold and when the amount of heat supplied by the heat exchanger 38 and / or the control electronics unit 44 is insufficient. The cooling circuit 16 also comprises a pipe 60 called "cold start line 60", a first end of which is connected in shunt between the battery radiator 54 and the electronic control unit 44 and a second end of which is arranged in upstream of the heat exchanger 38 and downstream of the first pump 48. A cold start valve 62 makes it possible to control selectively between at least two positions: a first cold start position in which the cooling fluid circulates; in a loop in the cold start line 60 and in the heating section 56 comprising the battery radiator 54 by simultaneously bypassing the electronic control unit 44 and the main radiator 46; a second heating position in which the cold start pipe 60 is closed when the electronic heating unit 44 exceeds a predetermined temperature. To allow the circulation of the cooling fluid in a loop when the cold start valve 62 is in the cold start position, a second pump 64 is arranged in the heating section 56, downstream of the cold start valve 62. and upstream of the heat exchanger 38. In a variant not shown of the invention, the cold start valve is capable of being controlled in a third position in which the pipe section comprising the battery radiator is short-circuited. The circulation of the cooling fluid between the main radiator and the electronic control unit is then ensured by the first pump. All the valves are, for example, solenoid valves which are automatically controlled as a function of various parameters including the temperature of the battery 10. With reference to FIG. 1, the operation of the thermal regulation device 12 according to different parameters, including the temperature of the battery 10 and the temperature of the electronic control unit 44. The thermal regulation device 12 can be controlled selectively between three operating states. As illustrated in FIG. 1, when the temperature of the battery 10 exceeds a determined upper threshold, the thermal regulation device 12 is controlled in a cooling state of the battery 10. The air conditioning circuit 14 then operates in "air-conditioning" mode. wherein the modulating valve 30 occupies its first air-conditioning position and wherein the bypass valve 42 occupies its first "direct" position. The flow of the cooling fluid is shown in bold in FIG. 1. In this cooling state, the temperature of the cooling fluid 5 passing through the heat exchanger 38 is insufficient to substantially modify the temperature of the cooling fluid. The cooling circuit 16 operates in turn so as to cool the electronic control unit 44. For this purpose, the heating valve 52 is controlled in its cooling position and the second cold start valve 62 is controlled in its heating position. When the thermal control device 12 is controlled in its cooling state, the battery 10 is normally cooled by the air conditioning circuit 14 and the electronic control unit 44 is cooled by the cooling circuit 16. The battery 10 is also partially cooled by the cooling circuit 16, the cooling fluid flowing through the battery radiator 54 having been previously cooled by the main radiator 46.
    [0013] As shown in FIG. 2, when the temperature of the battery 10 is lower than a lower temperature threshold, and when the electronic control unit 44 exceeds a predetermined temperature, the thermal control device 12 is controlled in a first state. The air conditioning circuit 14 is then controlled to operate in "heat pump" mode. Thus, the modulating valve 30 is controlled in its heat pump position, bypassing the evaporators 18, 20 via the modulating conduit 36. Similarly, the bypass valve 42 is controlled in its detent position to deflect the circulation of the air conditioning fluid to the expander 40. The loop followed by the air conditioning fluid, shown in bold in FIG. heat pump. Thus, the air conditioning fluid absorbs heat in the condenser 26. Then, at the outlet of the compressor 22, the compressed air conditioning fluid carries a large amount of heat. The heat exchanger 38 is the only member that allows the air conditioning fluid to give heat. Thus, a large amount of heat is passed to the cooling fluid through the heat exchanger 38.
    [0014] In the cooling circuit 16, the heating valve 52 is controlled to its heating position. Thus, the cooling fluid circulates in the loop shown in bold in Figure 2, without being cooled by the main radiator 46. The cold start valve 62 remains in its heating position. The cooling fluid is circulated by the first pump 48 and / or by the second pump 64. The cooling fluid thus absorbs the heat of the electronic control unit 44, and then absorbs the heat transmitted by the fluid 20 of the hot air conditioning through the heat exchanger 38. This thus makes it possible to cool the electronic control unit 44. The hot coolant then passes through the battery heater 54 to transmit at least a portion of the heat transported to the battery 10 to heat the latter. The cooling fluid thus cooled starts a new cycle. When the thermal control device 12 is controlled in its first heating state, the immersion heaters 58 are activated only when the electronic control unit 44 and the heat exchanger 38 are not hot enough to effectively heat the battery 10. As shown in FIG. 3, when the temperature of the battery 10 is lower than its lower temperature threshold, and when the electronic control unit 44 has a temperature lower than a second determined temperature, the thermal regulation device 12 is controlled in a second heating state called "cold start state".
    [0015] This second temperature is determined so that the electronic control unit 44 is not deteriorated. When the temperature of the electronic control unit 44 exceeds this determined temperature, it is considered that it is necessary to cool it. The thermal regulation device 12 is then controlled in its second heating state. In this cold start state, the air conditioning circuit 14 still operates in "heat pump" mode as explained for the first heating state of the thermal regulation device 12.
    [0016] In contrast, the cold start valve 62 of the cooling circuit 16 is controlled in its cold start position. The cooling fluid then circulated by the second pump 64 in the loop indicated in bold in FIG. 3. Thus, the cooling fluid is heated by passing through the heat exchanger 38. The hot coolant then passes into the battery heater 54 to warm the battery 10. The cooled fluid thus cooled is directly routed to the heat exchanger 38 via the cold start pipe 60 to start a new one. cycle. When the thermal control device 12 is controlled in its cold start state, the battery 10 is heated particularly efficiently by the air conditioning circuit 14 operating in heat pump mode because the cooling fluid does not lose heat in passing through the electronic control unit 44 cold. The thermal regulation device 12 made according to the teachings of the invention thus makes it possible to warm the battery 10 during a cold start, even when the electronic control unit 44 is cold, and without using the immersion heaters 58. The air conditioning circuit 14 operating in "heat pump" mode is used to heat the battery 10 with a much higher efficiency than that of an immersion heater. It is thus possible to heat the battery 10 with a lower power consumption than solutions using the immersion heaters. In addition, the thermal regulation of the battery 10 is particularly effective because the cooling of the battery 10 and the heating of the battery 10 are provided by two separate members. Thus, the battery evaporator 18 of the air-conditioning circuit 14 is dedicated to cooling the battery 10, while the battery radiator 54 of the cooling circuit 16 allows the battery 10 to be heated directly.
