Description
SYSTEME DE GESTION THERMIQUE DE VEHICULE ELECTRIQUE THERMAL MANAGEMENT SYSTEM OF ELECTRIC VEHICLE
La présente invention concerne le domaine de la gestion thermique au sein d'un véhicule électrique. Plus précisément, la présente invention traite d'un système de gestion thermique de différents éléments d'un véhicule électrique à pile à combustible. The present invention relates to the field of thermal management within an electric vehicle. More specifically, the present invention relates to a thermal management system of different elements of a fuel cell electric vehicle.
La gestion thermique d'un véhicule électrique à pile à combustible comporte notamment la gestion thermique d'organes dont la charge thermique à évacuer et le niveau de température associé sont variables. Par exemple, le compresseur d'air alimentant la pile à combustible et le moteur électrique du véhicule peuvent accepter un fluide de refroidissement avec une température pouvant aller jusqu'à 70°C, l'électronique de gestion peut quant à elle avoir un fluide de refroidissement avec une température pouvant aller jusqu'à 60°C et les batteries peuvent avoir une température du fluide de refroidissement pouvant aller jusqu'à 40°C environ. The thermal management of an electric fuel cell vehicle includes in particular the thermal management of organs whose heat load to be evacuated and the associated temperature level are variable. For example, the air compressor supplying the fuel cell and the electric motor of the vehicle can accept a cooling fluid with a temperature of up to 70 ° C, the management electronics can have a fluid of cooling with a temperature of up to 60 ° C and the batteries can have a coolant temperature of up to about 40 ° C.
Un organe tel que la pile à combustible en elle même, peut avoir une température comprise entre 60 et 95°C. Le fluide de refroidissement de l'air comprimé en direction de la pile à combustible peut quant à lui être soumis à une température maximale comprise entre 80 et 200°C, selon le taux de compression de l'air et la température ambiante. An organ such as the fuel cell itself may have a temperature between 60 and 95 ° C. The cooling fluid of the compressed air towards the fuel cell can itself be subjected to a maximum temperature of between 80 and 200 ° C., depending on the compression ratio of the air and the ambient temperature.
Il est ainsi connu d'élaborer un système de gestion thermique comportant deux boucles de gestion thermique regroupant différents organes du véhicule électrique. Une première boucle dite basse température, regroupant la gestion thermique du compresseur d'air, de l'électronique de puissance, du moteur électrique et des batteries. Une deuxième boucle dite haute température regroupant la gestion thermique de la pile à combustible et de l'air comprimé d'alimentation de cette dernière. Une troisième boucle dédiée à la climatisation du véhicule électrique peut également être ajoutée. It is thus known to develop a thermal management system comprising two thermal management loops grouping different organs of the electric vehicle. A first so-called low temperature loop, combining the thermal management of the air compressor, the power electronics, the electric motor and the batteries. A second so-called high temperature loop comprising the thermal management of the fuel cell and the compressed air supply thereof. A third loop dedicated to the air conditioning of the electric vehicle can also be added.
Afin d'évacuer la charge thermique de ces différentes boucles, des radiateurs sont disposés en face avant du véhicule automobile, aussi bien dans un module de face avant frontal, c'est à dire situé au niveau de la calandre du véhicule, ou bien même au niveau de modules additionnels latéraux de face avant, par exemple situés au niveau des passages de roues, afin d'augmenter la surface d'échange. In order to evacuate the thermal load of these different loops, radiators are arranged on the front face of the motor vehicle, both in a frontal front-end module, ie located at the level of the radiator grille of the vehicle, or even at level of front side additional modules, for example located at the wheel arches, to increase the exchange surface.
Cependant, à faible vitesse et lorsqu'une forte puissance est demandée à la pile à combustible, le flux d'air traversant les différents radiateurs peut ne pas être suffisant pour assurer un échange thermique et une capacité de transport de la chaleur suffisants, notamment avec la boucle dite haute température qui a la charge thermique à évacuer la plus élevée. Le refroidissement de l'air comprimé d'alimentation de la pile à combustible se fait donc moins bien, diminuant à la fois la puissance maximale disponible et le rendement de ladite pile à combustible. However, at low speed and when a high power is required from the fuel cell, the air flow through the various radiators may not be sufficient to ensure sufficient heat exchange and heat transport capacity, particularly with the so-called high temperature loop which has the highest thermal load to evacuate. The cooling of the compressed fuel supply of the fuel cell is therefore less well, decreasing both the maximum available power and the efficiency of said fuel cell.
Un des buts de l'invention est donc de remédier au moins partiellement aux inconvénients de l'art antérieur et de proposer un système de gestion thermique pour véhicule électrique à pile à combustible amélioré. La présente invention concerne donc un système de gestion thermique d'un véhicule automobile électrique comportant une pile à combustible, ledit système comportant : One of the aims of the invention is therefore to at least partially overcome the disadvantages of the prior art and to propose a thermal management system for an electric vehicle with an improved fuel cell. The present invention thus relates to a thermal management system of an electric motor vehicle comprising a fuel cell, said system comprising:
0 une première boucle de régulation thermique dite basse température dans laquelle circule un premier fluide caloporteur et comprenant : 0 a first so-called low temperature thermal control loop in which a first heat transfer fluid circulates and comprising:
■ un dispositif d'échange thermique avec un compresseur d'air alimentant en air la pile à combustible, A heat exchange device with an air compressor supplying the fuel cell with air,
■ au moins un premier radiateur dédié, disposé au niveau de la face avant du véhicule électrique, ■ at least one first radiator dedicated disposed at the front of the electric vehicle,
0 une deuxième boucle de régulation thermique dite haute température dans laquelle circule un deuxième fluide caloporteur et comprenant : 0 a second loop of said high temperature thermal control in which circulates a second coolant and comprising:
■ un dispositif d'échange thermique avec la pile à combustible, et ■ a heat exchange device with the fuel cell, and
■ au moins un deuxième radiateur dédié, disposé au niveau de la face avant du véhicule électrique, 0 une troisième boucle de régulation thermique dite très haute température dans laquelle circule un troisième fluide caloporteur et comprenant : ■ at least one second dedicated radiator disposed at the front of the electric vehicle, 0 a third thermal control loop said very high temperature in which circulates a third heat transfer fluid and comprising:
■ un dispositif d'échange thermique avec l'air comprimé d'alimentation en provenance du compresseur d'air d'alimentation, et ■ a heat exchange device with the compressed feed air from the feed air compressor, and
■ un troisième radiateur dédié, disposé au niveau de la face avant du véhicule électrique. A third dedicated radiator disposed at the front of the electric vehicle.

Le fait d'avoir trois boucles de gestion thermique distinctes au sein du système de gestion thermique 1 et notamment d'avoir une troisième boucle 300 spécifique à l'air comprimé d'alimentation de la pile à combustible, permet de faire travailler les radiateurs dédiés 105, 203 et 303 placés en face avant 10 du véhicule automobile électrique à la température maximum des différentes boucles, évitant ainsi une dilution des températures des fluides caloporteur. Chaque organe est donc refroidi à la température maximale autorisée selon ses besoins. Ainsi, l'air comprimé d'alimentation et la pile à combustible sont gérés indépendamment, ce qui permet d'optimiser la densité de puissance et le rendement de la pile à combustible. Within this third very high temperature loop 300, the temperature of the third heat transfer fluid before entering the third dedicated radiator is greater than the temperature of the second heat transfer fluid at the outlet of the heat exchange device 201 with the fuel cell, either an average temperature above 90 ° C. The fact of having three separate thermal management loops within the thermal management system 1 and in particular having a third loop 300 specific to the compressed air supply of the fuel cell, makes it possible to work the dedicated radiators 105, 203 and 303 placed on the front face 10 of the electric motor vehicle at the maximum temperature of the various loops, thus avoiding a dilution of the temperatures of the heat transfer fluids. Each member is therefore cooled to the maximum permitted temperature according to its needs. Thus, the compressed supply air and the fuel cell are managed independently, which optimizes the power density and efficiency of the fuel cell.
Afin d'avoir une évacuation de la chaleur optimale, et selon un premier mode de réalisation illustré à la figure 1, un premier radiateur dédié 105 ainsi qu'un deuxième radiateur dédié 203 peuvent être disposés au sein d'un module frontal de face avant de véhicule automobile, c'est à dire au niveau de la calandre du véhicule électrique. In order to have optimal heat dissipation, and according to a first embodiment illustrated in FIG. 1, a first dedicated radiator 105 and a second dedicated radiator 203 may be arranged within a front-end front module. of a motor vehicle, ie at the level of the grille of the electric vehicle.
Le troisième radiateur dédié 303 est quant à lui de préférence disposé au sein d'au moins un module additionnel latéral de face avant du véhicule électrique, c'est à dire sur les côtés de la face avant, au niveau des passages de roues. Il est néanmoins possible d'imaginer que le troisième radiateur dédié 303 puisse être disposé au sein du module frontal de face avant de véhicule automobile. The third dedicated radiator 303 is for its part preferably disposed within at least one additional lateral module of the front face of the electric vehicle, that is to say on the sides of the front face, at the wheel arches. It is nevertheless possible to imagine that the third dedicated radiator 303 can be disposed within the frontal module of the front face of a motor vehicle.
Que ce soit au sein du module frontal de face avant de véhicule automobile ou au sein d'au moins un module additionnel latéral de face avant du véhicule électrique, le troisième radiateur dédié 303 est disposé le plus en aval possible par rapport à un premier 105 ou un deuxième 203 radiateur dédié dans le sens du flux d'air 11. En effet, la température du troisième fluide caloporteur en entrée du troisième radiateur dédié 303 est la plus élevée entre celles du premier et du deuxième fluide caloporteur respectivement aux entrées des premier 105 et deuxième 203 radiateurs dédiés. Selon un second mode de réalisation illustré à la figure 2, un premier radiateur dédié 105 est disposé, à l'instar du troisième radiateur dédié 303, au sein d'au moins un module additionnel latéral de face avant du véhicule électrique. Selon un autre mode de réalisation non représenté, la première boucle 100 basse température peut comporter au moins deux premiers radiateurs dédiés 105 reliés en série ou en parallèle. Au moins un premier radiateur dédié 105 est alors disposé au sein d'au moins un module additionnel latéral de face avant du véhicule électrique et au moins un autre premier radiateur dédié 105 est disposé au sein d'un module frontal de face avant du véhicule électrique. Whether in the front end module of a motor vehicle or in at least one additional front side module of the electric vehicle, the third dedicated radiator 303 is disposed as downstream as possible relative to a first 105 or a second 203 dedicated radiator in the direction of the air flow 11. In fact, the temperature of the third heat transfer fluid at the inlet of the third dedicated radiator 303 is the highest between those of the first and second heat transfer fluid respectively at the inputs of the first 105 and second 203 dedicated radiators. According to a second embodiment illustrated in FIG. 2, a first dedicated radiator 105 is disposed, like the third dedicated radiator 303, within at least one additional lateral module of the front face of the electric vehicle. According to another embodiment not shown, the first low temperature loop 100 may comprise at least two first dedicated radiators 105 connected in series or in parallel. At least one first dedicated radiator 105 is then disposed within at least one additional front side module of the electric vehicle and at least one other first dedicated radiator 105 is disposed within a front end module of the electric vehicle. .
De même, la deuxième boucle 200 haute température peut comporter au moins deux deuxièmes radiateurs dédiés 203 reliés en série ou en parallèle. Au moins un deuxième radiateur dédié 203 est alors disposé au sein d'au moins un module additionnel latéral de face avant du véhicule électrique et au moins un autre deuxième radiateur dédié 203 est disposé au sein d'un module frontal de face avant du véhicule électrique. Similarly, the second high temperature loop 200 may comprise at least two second dedicated radiators 203 connected in series or in parallel. At least one second dedicated radiator 203 is then disposed within at least one additional front side module of the electric vehicle and at least one other second dedicated radiator 203 is disposed within a front end module of the electric vehicle. .
Que ce soit au sein du module frontal de face avant de véhicule automobile ou au sein d'au moins un module additionnel latéral de face avant du véhicule électrique, le premier radiateur dédié 105 est disposé le plus en amont possible par rapport à un deuxième 203 ou un troisième 303 radiateur dédié dans le sens du flux d'air 11. En effet, la température du premier fluide caloporteur en entrée du premier radiateur dédié 105 est la plus faible entre celles du deuxième et du troisième fluide caloporteur respectivement aux entrées des deuxième 203 et troisième 303 radiateurs dédiés. Whether in the front end module of a motor vehicle or in at least one additional front side module of the electric vehicle, the first dedicated radiator 105 is disposed as far upstream as possible relative to a second 203 or a third 303 dedicated radiator in the direction of the air flow 11. In fact, the temperature of the first heat transfer fluid at the inlet of the first dedicated radiator 105 is the lowest between those of the second and third heat transfer fluid respectively at the entrances of the second 203 and third 303 dedicated radiators.
Ainsi, au sein d'un même module additionnel latéral de face avant du véhicule électrique ou d'un même module frontal de face avant du véhicule électrique, le premier radiateur dédié 105 est placé en amont du deuxième 203 ou troisième 303 radiateur dédié, dans le sens de circulation du flux d'air 11 les traversant. Comme montré sur les figures 1 et 2, la seconde boucle 200 haute température peut également comporter un premier échangeur thermique supplémentaire 209 connecté parallèlement au dispositif d'échange thermique 201 avec la pile à combustible. Par connecté parallèlement, on entend, à l'instar des branchements dans le domaine électrique, que les entrées de troisième fluide caloporteur du dispositif d'échange thermique 201 avec la pile à combustible et du premier échangeur thermique supplémentaire 209, sont toutes deux connectées à la sortie de la deuxième pompe et que leurs sorties sont toutes deux connectées au deuxième radiateur dédié 203. Ledit premier échangeur thermique supplémentaire 209 est disposé, dans le flux d'air comprimé 21 d'alimentation en sortie du compresseur d'air d'alimentation, en aval du dispositif d'échange thermique 301 avec l'air comprimé d'alimentation de la troisième boucle 300 très haute température. Ce premier échangeur thermique supplémentaire 209 permet d'amener l'air comprimé d'alimentation à une température proche de celle de la pile à combustible et ainsi permet d'accélérer la mise en température de la pile à combustible après son démarrage et d'assurer une température homogène au sein de la pile pour améliorer son rendement et sa durée de vie. Thus, within the same additional front side module of the electric vehicle or the same frontal module of the front of the electric vehicle, the first dedicated radiator 105 is placed upstream of the second 203 or third 303 dedicated radiator, in the flow direction of the air flow 11 passing through them. As shown in FIGS. 1 and 2, the second high temperature loop 200 may also comprise a first additional heat exchanger 209 connected in parallel with the heat exchange device 201 with the fuel cell. By parallel connected means, as connections in the electrical field, that the third heat transfer fluid inlet of the heat exchange device 201 with the fuel cell and the first additional heat exchanger 209, are both connected to the output of the second pump and that their outputs are both connected to the second dedicated radiator 203. Said first additional heat exchanger 209 is disposed in the flow of compressed air 21 for supplying the output of the supply air compressor , downstream of the heat exchange device 301 with the compressed air supply of the third loop 300 at a very high temperature. This first additional heat exchanger 209 makes it possible to bring the compressed supply air to a temperature close to that of the fuel cell and thus makes it possible to accelerate the temperature setting of the fuel cell after it has been started and to ensure a homogeneous temperature within the cell to improve its performance and its lifetime.
Le dispositif d'échange thermique 301 avec l'air d'alimentation comprimé de la troisième boucle 300 très haute température et le premier échangeur thermique supplémentaire 209 de la seconde boucle 200 haute température peuvent être accolés l'un à l'autre. Selon un autre mode de réalisation, le dispositif d'échange thermique 301 avec l'air d'alimentation comprimé et le premier échangeur thermique supplémentaire 209 sont regroupés au sein d'un même échangeur de chaleur comportant un premier circuit interne de circulation du troisième fluide caloporteur et un deuxième circuit interne de circulation du deuxième fluide caloporteur. The heat exchange device 301 with the compressed feed air of the third very high temperature loop 300 and the first additional heat exchanger 209 of the second high temperature loop 200 can be contiguous to each other. According to another embodiment, the heat exchange device 301 with the compressed feed air and the first additional heat exchanger 209 are grouped together in the same heat exchanger comprising a first internal circulation circuit of the third fluid. coolant and a second internal circulation circuit of the second heat transfer fluid.
La seconde boucle 200 haute température peut également comporter un second échangeur thermique supplémentaire 214 connecté entre le dispositif d'échange thermique 201 avec la pile la combustible et le deuxième radiateur dédié 203. Ce second échangeur thermique supplémentaire 214 est disposé dans le flux de combustible arrivant à la pile à combustible afin d'amener ce dernier à une température proche de celle de la pile à combustible et ainsi d'améliorer son rendement et sa durée de vie. Comme illustré à la figure 2, la seconde boucle 200 haute température peut en outre comporter : The second high temperature loop 200 may also comprise a second additional heat exchanger 214 connected between the heat exchange device 201 with the fuel cell and the second dedicated radiator 203.

0 un échangeur de chaleur complémentaire 211 disposé au sein d'un dispositif d'alimentation en air de l'habitacle du véhicule automobile. 0 a complementary heat exchanger 211 disposed within a device for supplying air to the passenger compartment of the motor vehicle.
La vanne trois-voies 210 permet de rediriger le deuxième fluide caloporteur en provenance du dispositif d'échange thermique 201 avec la pile la combustible soit directement vers le deuxième radiateur dédié 203 ou alors vers l'échangeur de chaleur complémentaire 211, le deuxième fluide réfrigérant rejoignant ensuite ledit deuxième radiateur dédié 203. Par la gestion de cette vanne trois-voies 209, il est ainsi possible d'utiliser la chaleur émise par la pile à combustible et également une partie de la chaleur de l'air comprimé d'alimentation pour chauffer un flux d'air 31 allant en direction de l'habitacle du véhicule automobile. The three-way valve 210 makes it possible to redirect the second heat transfer fluid from the heat exchange device 201 with the fuel cell either directly to the second dedicated radiator 203 or else to the complementary heat exchanger 211, the second refrigerant fluid. then joining said second dedicated radiator 203. By the management of this three-way valve 209, it is thus possible to use the heat emitted by the fuel cell and also a portion of the heat of the compressed air supply for heating an air flow 31 towards the passenger compartment of the motor vehicle.
Afin d'améliorer cet aspect de chauffage du flux d'air 31 allant en direction de l'habitacle du véhicule automobile, la deuxième boucle 200 haute température peut également comporter un dispositif de chauffage électrique 213 du deuxième fluide caloporteur disposé entre la vanne trois-voies 209 et l'échangeur de chaleur complémentaire 211. In order to improve this heating aspect of the air flow 31 towards the cabin of the motor vehicle, the second high temperature loop 200 may also include an electric heating device 213 of the second heat transfer fluid disposed between the three-way valve. channels 209 and the complementary heat exchanger 211.
La figure 2 montre également que le système de gestion thermique 1 peut également comporter une quatrième boucle de climatisation 400, dans laquelle circule un fluide réfrigérant et dédiée à la gestion thermique du flux d'air 31 allant en direction de l'habitacle du véhicule automobile. FIG. 2 also shows that the thermal management system 1 may also comprise a fourth air-conditioning loop 400, in which circulates a refrigerant fluid and dedicated to the thermal management of the airflow 31 going towards the passenger compartment of the motor vehicle .
La quatrième boucle 400 de climatisation comporte notamment : The fourth air conditioning loop 400 comprises in particular:
0 un compresseur 401 , 0 a compressor 401,
0 un condenseur 403 disposé au niveau de la face avant 10 du véhicule automobile électrique, en aval du compresseur 401, 0 un dispositif de détente 405 en aval du condenseur 403, et 0 a condenser 403 disposed at the front face 10 of the electric motor vehicle, downstream of the compressor 401, 0 an expansion device 405 downstream of condenser 403, and
0 un évaporateur 407 disposé au sein d'un dispositif d'alimentation en air de l'habitacle du véhicule automobile, entre le dispositif de détente 405 et le compresseur 401. 0 an evaporator 407 disposed within a feeder air from the interior of the motor vehicle, between the expansion device 405 and compressor 401.
Le condenseur 403 est de préférence disposé au sein d'un module frontal de face avant du véhicule automobile en amont du deuxième radiateur dédié 203 de la deuxième boucle 200 haute température, dans le sens de circulation du flux d'air 11 les traversant. The condenser 403 is preferably disposed within a front end module of the motor vehicle upstream of the second dedicated radiator 203 of the second high temperature loop 200, in the flow direction of the air flow 11 therethrough.
Dans le cas où le premier radiateur dédié 105 de la premier boucle 100 basse température est également disposé au sein d'un module frontal de face avant du véhicule automobile, le condenseur 403 est positionné entre le deuxième radiateur dédié 203 de la deuxième boucle 200 haute température et le premier radiateur dédié 105 de la première boucle 100 basse température. In the case where the first dedicated radiator 105 of the first low temperature loop 100 is also disposed within a front end module of the motor vehicle, the condenser 403 is positioned between the second dedicated radiator 203 of the second high loop 200 temperature and the first dedicated radiator 105 of the first loop 100 low temperature.
Sur les figures 3a et 3b, seules les boucles en interconnections sont représentées dans leur intégralité afin d'améliorer la compréhension. In Figures 3a and 3b, only the interconnected loops are shown in their entirety to improve understanding.
Comme illustré à la figure 3a, la première boucle 100 basse température et la quatrième boucle 400 de climatisation peuvent comporter un premier échangeur de chaleur bi-fluide 501 entre le premier fluide caloporteur et le fluide réfrigérant. Ce premier échangeur de chaleur bi-fluide 501 est disposé au sein de la quatrième boucle 400 de climatisation en amont du condenseur 403. Au sein de la première boucle 100 basse température, le premier échangeur de chaleur bi-fluide 501 peut tout aussi bien être placé en amont ou en aval du premier radiateur dédié 105. As illustrated in FIG. 3a, the first low temperature loop 100 and the fourth air conditioning loop 400 may comprise a first bi-fluid heat exchanger 501 between the first heat transfer fluid and the refrigerant fluid. This first bi-fluid heat exchanger 501 is disposed within the fourth air conditioning loop 400 upstream of the condenser 403. Within the first low temperature loop 100, the first bi-fluid heat exchanger 501 can equally well be placed upstream or downstream of the first dedicated radiator 105.
Comme illustré sur la figure 3b, la troisième boucle 300 très haute température et la quatrième boucle 400 de climatisation peuvent également comporter un deuxième échangeur de chaleur bi-fluide 503 entre le troisième fluide caloporteur et le fluide réfrigérant. Ce deuxième échangeur de chaleur bi-fluide 503 est disposé au sein de la quatrième boucle 400 de climatisation en amont du condenseur 403. Au sein de la troisième boucle 300 très haute température, le deuxième échangeur de chaleur bi-fluide 503 peut tout aussi bien être placé en amont ou en aval du troisième radiateur dédié 303. Ces premier et deuxième échangeur de chaleur bi-fluide 501 et 503 permettent un refroidissement supplémentaire du fluide réfrigérant de la quatrième boucle 400 de climatisation. En effet, si le fluide réfrigérant est par exemple du C02, il peut atteindre des températures maximum de l'ordre de 150°C ce qui est bien supérieur aux températures du premier fluide réfrigérant de la premier boucle 100 basse température et même du troisième fluide réfrigérant de la troisième boucle 300 très haute température. Ces premier et deuxième échangeurs de chaleur bi-fluide 501 et 503 permettent donc, à refroidissement du fluide réfrigérant équivalent, d'avoir un condenseur 403 de plus petite taille. As illustrated in FIG. 3b, the third very high temperature loop 300 and the fourth air conditioning loop 400 may also comprise a second bi-fluid heat exchanger 503 between the third heat transfer fluid and the refrigerant fluid. This second bi-fluid heat exchanger 503 is disposed within the fourth air conditioning loop 400 upstream of the condenser 403. Within the third very high temperature loop 300, the second bi-fluid heat exchanger 503 can equally well be placed upstream or downstream of the third dedicated radiator 303. These first and second bi-fluid heat exchangers 501 and 503 allow additional cooling of the cooling fluid of the fourth air conditioning loop 400. Indeed, if the refrigerant is for example C0 2 , it can reach maximum temperatures of the order of 150 ° C which is much higher than the temperatures of the first refrigerant fluid of the first loop 100 low temperature and even the third refrigerant fluid of the third loop 300 very high temperature. These first and second bi-fluid heat exchangers 501 and 503 thus make it possible, for cooling the equivalent refrigerant, to have a condenser 403 of smaller size.
Ainsi, on voit bien que le système de gestion thermique 1 selon l'invention permet de part la présence d'une troisième boucle 300 très haute température, dédiée à la gestion thermique de l'air comprimé alimentation, une meilleure gestion thermique du véhicule électrique. Thus, it is clear that the thermal management system 1 according to the invention allows for the presence of a third loop 300 very high temperature, dedicated to the thermal management of compressed air supply, better thermal management of the electric vehicle .
