Description

Système de cogénération d'énergie pour véhicule automobile électrique.  Energy cogeneration system for an electric motor vehicle.
L'invention concerne un système de cogénération d'énergie pour véhicule automobile électrique. The invention relates to an energy cogeneration system for an electric motor vehicle.
On sait que certains véhicules automobiles électriques comportent un système de génération électrique embarqué, généralement appelé prolongateur d'autonomie, qui est activé en cas de besoin relativement à l'état de charge de la batterie d'entraînement du véhicule.  It is known that certain electric motor vehicles include an on-board electrical generation system, generally called a range extender, which is activated when necessary with regard to the state of charge of the vehicle's driving battery.
Le prolongateur d'autonomie peut être par exemple un moteur thermique associé à une génératrice électrique ou encore une pile à combustible alimentée par un mélange gazeux, dit réformat, riche en hydrogène, produit à bord du véhicule à partir d'un carburant liquide, tel que l'éthanol.  The range extender may be for example a heat engine associated with an electric generator or a fuel cell fueled by a gas mixture, said reformate, rich in hydrogen, produced on board the vehicle from a liquid fuel, such as than ethanol.
On connaît également les thermo générateurs à effet Seebeck qui permettent de récupérer une partie de l'énergie thermique des gaz d'échappement du prolongateur d'autonomie, par exemple l'énergie thermique des gaz d'échappement constitue environ un tiers de l'énergie contenue dans le carburant dans le cas d'un prolongateur d'autonomie à moteur thermique et génératrice de courant.  Seebeck thermo-generators are also known which make it possible to recover a part of the thermal energy of the exhaust gas of the range extender, for example the thermal energy of the exhaust gases constitutes approximately one-third of the energy contained in the fuel in the case of a range extender with thermal engine and current generator.
Ces thermo générateurs produisent de l'électricité à partir d'une source thermique chaude, qui est par exemple les gaz d'échappement du moteur thermique de prolongateur d'autonomie, et d'un puit thermique froid (de température inférieure à celle de la source chaude) et qui peut être un liquide de refroidissement d'un organe du véhicule.  These thermo generators produce electricity from a hot thermal source, which is for example the exhaust of the range extender heat engine, and a cold thermal sink (lower temperature than that of the hot source) and which can be a coolant of a vehicle body.
Néanmoins, les thermo générateurs à effet Seebeck connus n'utilisent qu'une seule source froide, laquelle, en raison du transfert de chaleur de la source chaude à la source froide, peut être amenée à chauffer et par conséquent la production d'énergie électrique de ces thermo générateurs diminue.  Nevertheless, the known Seebeck effect thermo-generators use only one cold source, which, because of the transfer of heat from the hot source to the cold source, can be brought to heat and consequently the production of electrical energy of these thermo generators decreases.
Il existe un besoin pour améliorer la production d'énergie électrique de ces thermo générateurs à effet Seebeck sur les véhicules automobiles électriques. Par ailleurs, les dispositifs actuels ne permettent pas de valoriser la chaleur transférée à la source froide (puit thermique froid) du thermo générateur à effet Seebeck. There is a need to improve the electrical power generation of these Seebeck effect thermo generators on electric motor vehicles. Furthermore, the current devices do not allow to value the heat transferred to the cold source (cold thermal sink) of the Seebeck effect thermo generator.
Il existe donc également un besoin pour valoriser la chaleur transférée à la source froide.  There is therefore also a need to value the heat transferred to the cold source.

Il peut s'agir d'un circuit de refroidissement-chauffage de l'habitacle du véhicule, d'un circuit de refroidissement-chauffage de la batterie de traction du véhicule, d'un circuit de refroidissement- chauffage des composants électrotechniques ou d'un circuit de refroidissement-chauffage du moteur thermique du dispositif prolongateur d'autonomie. Au sens de l'invention, l'organe peut donc être un élément fonctionnel du véhicule (batterie, moteur, ...) ou une zone de ce dernier (habitacle).

Dans la présente description, les termes amont et aval sont à comprendre par rapport au sens de circulation du fluide dans les circuits.  In the present description, the terms upstream and downstream are to be understood with respect to the direction of circulation of the fluid in the circuits.
Un tel système permet d'optimiser la récupération de l'énergie thermique d'un fluide chaud constitué par exemple des gaz chauds de combustion produits par le dispositif de prolongateur d'autonomie, cette récupération étant réalisée sous forme d'énergie électrique pour recharger la batterie de traction ou alimenter des organes accessoires électriques du véhicule, ou alimenter le moteur de traction du véhicule, ou étant réalisée sous forme d'énergie thermique par l'apport de chaleur de la source chaude à la source froide pour réchauffer le circuit de refroidissement-chauffage de l'organe du véhicule sélectionné, par exemple le circuit de refroidissement-chauffage de l'habitacle, le circuit de refroidissement- chauffage de la batterie de traction pour que cette dernière fonctionne dans sa zone de température optimale, le circuit de refroidissement du moteur thermique par exemple au début de son fonctionnement pour que ce dernier atteigne plus rapidement sa température de fonctionnement optimale ou un autre fluide du véhicule.  Such a system makes it possible to optimize the recovery of the thermal energy of a hot fluid consisting, for example, of the hot combustion gases produced by the autonomy extension device, this recovery being carried out in the form of electrical energy to recharge the battery. a traction battery or supplying electrical accessory parts of the vehicle, or supplying the traction motor of the vehicle, or being produced in the form of thermal energy by the supply of heat from the hot source to the cold source for heating the cooling circuit -heating of the selected vehicle member, for example the cooling-heating circuit of the passenger compartment, the cooling-heating circuit of the traction battery for the latter to operate in its optimum temperature zone, the cooling circuit the engine for example at the beginning of its operation so that the latter reaches its temperature more quickly erasure optimum operating or other vehicle fluid.
Chaque circuit de refroidissement-chauffage d'organe dudit véhicule est avantageusement relié, en aval de l'organe, à la source froide de manière à 'alimenter cette source froide en fluide circulant dans ledit circuit. Les circuits de refroidissement-chauffage sont alors fermés, et le système peut comporter une pluralité de circuits de chauffage-refroidissement d'organe montés en parallèle sur la source froide, chaque circuit étant pourvu d'une électrovanne à trois voies ouvrant ou fermant l'alimentation dudit circuit.  Each organ cooling-heating circuit of said vehicle is advantageously connected, downstream of the member, to the cold source so as to supply this cold source with fluid flowing in said circuit. The cooling-heating circuits are then closed, and the system may include a plurality of organ heating-cooling circuits connected in parallel with the cold source, each circuit being provided with a three-way solenoid valve opening or closing the feeding said circuit.
De manière générale, dans le cas de circuits de refroidissement- chauffage fermés, le système selon l'invention pourra comprendre un dispositif de basculement en amont et/ ou en aval desdits circuits.  In general, in the case of closed cooling-heating circuits, the system according to the invention may comprise a tilting device upstream and / or downstream of said circuits.
En variante, le fluide peut être un fluide caloporteur gazeux.  Alternatively, the fluid may be a gaseous coolant.
En particulier, la source froide peut alors être directement alimentée par l'air extérieur. Les circuits de refroidissement-chauffage sont alors ouverts et le système peut comporter une pluralité de circuits de refroidissement-chauffage d'un fluide caloporteur gazeux, et au moins un élément clapet de distribution du fluide caloporteur sortant de la source froide sur au moins l'un des circuits, voire dans l'environnement extérieur. In particular, the cold source can then be directly powered by the outside air. The cooling-heating circuits are then opened and the system can comprise a plurality of cooling-heating circuits of a gaseous heat-transfer fluid, and at least one valve element for distributing the heat-transfer fluid leaving the cold source on at least one of the circuits, or even in the external environment.
Bien entendu, des circuits fermés peuvent également être envisagés pour un fluide caloporteur gazeux lorsque ce dernier ne peut être rejeté dans l'air.  Of course, closed circuits may also be considered for a gaseous coolant when the latter can not be released into the air.
Le dispositif de commande peut être apte à commander le dispositif de basculement afin de basculer l'alimentation en fluide sortant de la source froide d'au moins un circuit de refroidissement- chauffage vers au moins un autre en fonction d'une consigne choisie parmi une consigne de température maximale dudit circuit, une consigne de rendement optimal du système ou de l'écart optimal entre la source froide et la source chaude, une consigne de température dans l'habitacle.  The control device may be able to control the tilting device in order to switch the supply of fluid leaving the cold source of at least one cooling-heating circuit to at least one other according to a setpoint chosen from a maximum temperature setpoint of said circuit, a setpoint of optimum efficiency of the system or of the optimum difference between the cold source and the hot source, a set temperature in the passenger compartment.
Le dispositif de basculement peut comporter au moins un élément clapet ou électrovanne de distribution du fluide issu de la source froide pour alimenter l'au moins un circuit de refroidissement- chauffage, par exemple des électrovannes à trois voies (ouvrant ou fermant chaque circuit) montées sur les conduits d'alimentation des circuits montés en parallèle sur la source froide.  The tilting device may comprise at least one valve element or solenoid valve for distributing the fluid coming from the cold source to supply the at least one cooling-heating circuit, for example three-way solenoid valves (opening or closing each circuit) mounted. on the supply ducts of the circuits connected in parallel on the cold source.

Dans le cas où le fluide caloporteur est un liquide, l'échangeur thermique du dispositif thermo générateur à effet Seebeck est du type gaz liquide, et dans le cas où le fluide caloporteur est un gaz, l'échangeur thermique est du type gaz gaz.  In the case where the heat transfer fluid is a liquid, the heat exchanger of the Seebeck effect thermo-generator device is of the liquid gas type, and in the case where the coolant is a gas, the heat exchanger is of the gas gas type.
Le dispositif de commande peut être à pilotage automatique ou à pilotage manuel.  The control device can be autopilot or manual control.
Le pilotage automatique peut être réalisé selon une consigne de rendement énergétique optimal du dispositif de thermo générateur à effet Seebeck, préservant un écart optimal de température entre la source chaude et la source froide, ou selon une consigne de confort dans le véhicule, préservant la température dans l'habitacle du véhicule, ou selon une consigne de fonctionnement optimal des organes d'entraînement du véhicule, préservant par exemple la température de la batterie de traction, ou du moteur thermique (en début de fonctionnement) du dispositif de prolongateur d'autonomie etc....

Il est en outre proposé un procédé de mise en œuvre d'un système tel que décrit précédemment, dans lequel la source froide est alimentée par un fluide, et dans lequel ce fluide réchauffé par son passage dans la source froide, est renvoyé dans au moins un circuit de refroidissement-chauffage d'organe du véhicule, en amont de l'organe.  It is furthermore proposed a method of implementing a system as described above, in which the cold source is fed with a fluid, and in which this fluid is heated by passing through the cold source, is returned to at least one a vehicle body cooling-heating circuit, upstream of the member.
Le fluide alimentant la source froide peut être un fluide caloporteur gazeux, tel que l'air extérieur du véhicule, ou un fluide caloporteur liquide, tel que l'eau, circulant dans l'un des circuits de refroidissement-réchauffage d'un organe du véhicule, prélevé en aval de cet organe.  The fluid supplying the cold source may be a gaseous coolant, such as the outside air of the vehicle, or a liquid heat transfer fluid, such as water, circulating in one of the cooling-heating circuits of a body of the vehicle, taken downstream of this organ.
Le fluide sortant de la source froide est dirigé par le dispositif de basculement vers au moins un circuit de refroidissement-chauffage en fonction d'une consigne choisie parmi une consigne de température maximale dudit circuit, une consigne de rendement optimal du système ou de l'écart optimal entre la source froide et la source chaude, une consigne de température dans l'habitacle.  The fluid exiting the cold source is directed by the tilting device to at least one cooling-heating circuit as a function of a setpoint chosen from a maximum temperature setpoint of said circuit, an optimal performance setpoint of the system or the optimal distance between the cold source and the hot source, a set temperature in the passenger compartment.
Il est encore proposé un véhicule électrique comportant un système de cogénération d'énergie tel que décrit ci-dessus.  It is also proposed an electric vehicle comprising a system of energy cogeneration as described above.
Le système selon l'invention peut permettre d'assurer seul la gestion thermique de plusieurs organes du véhicule.  The system according to the invention can make it possible to ensure alone the thermal management of several organs of the vehicle.
On peut toutefois envisager que le système selon l'invention soit couplé à des circuits de refroidissement-chauffage classiques des organes d'un véhicule électrique. On peut notamment envisager que chaque organe (ou certains des organes) soit en outre refroidi-chauffé par un autre circuit de refroidissement-chauffage, par exemple monté en parallèle sur le circuit correspondant du système selon l'invention. Des modes de réalisation de l'invention sont à présent décrits à titre d'exemple non limitatif et en référence au dessin annexé sur lequel : - La fig. 1 est une vue schématique d'un système de cogénération d'énergie pour véhicule électrique selon un mode de réalisation de l'invention, et However, it can be envisaged that the system according to the invention is coupled to conventional cooling-heating circuits of the components of an electric vehicle. It can be envisaged that each member (or some of the members) is further cooled-heated by another cooling-heating circuit, for example connected in parallel to the corresponding circuit of the system according to the invention. Embodiments of the invention are now described by way of non-limiting example and with reference to the appended drawing in which: - Fig. 1 is a schematic view of an energy vehicle cogeneration system for an electric vehicle according to one embodiment of the invention, and
- La fig. 2 est une vue analogue à la fig. 1 d'une variante de réalisation.  - Fig. 2 is a view similar to FIG. 1 of an alternative embodiment.
Avec référence au dessin, le système de cogénération d'énergie 1 pour véhicule électrique représenté comprend un dispositif prolongateur d'autonomie 3 du véhicule dont on voit seul un conduit 5 de sortie des gaz de combustion, par exemple du moteur thermique d'entraînement de génératrice électrique.  With reference to the drawing, the energy cogeneration system 1 for an electric vehicle shown comprises an extension device 3 of the vehicle which is seen only a conduit 5 for output of the combustion gases, for example the thermal drive motor. electric generator.
Ce dispositif prolongateur d'autonomie 3 est relié à un dispositif thermo générateur 7 à effet Seebeck comportant un premier échangeur thermique 9 recevant les gaz de combustion du conduit 5 de sortie des gaz précité en tant que source chaude du dispositif thermo-générateur.  This autonomy extension device 3 is connected to a Seebeck effect thermo generator device 7 comprising a first heat exchanger 9 receiving the combustion gases of the aforementioned gas outlet pipe 5 as a hot source of the thermo-generator device.
Un second échangeur thermique 1 1 en tant que source froide du dispositif thermo générateur à effet Seebeck reçoit un fluide caloporteur, par exemple de l'eau 13 ou de l'air circulant selon flèches vers divers circuits de refroidissement-chauffage du véhicule, par exemple le circuit 15 de refroidissement-chauffage de la batterie de traction (T maximale à environ 50°C), le circuit 17 de refroidissement- chauffage de l'habitacle du véhicule, le circuit 19 de refroidissement du moteur thermique du dispositif prolongateur d'autonomie (T maximale à environ 100- 1 10°C) ou encore (non représenté) un circuit de refroidissement des composants électrotechniques du véhicule (moteur électrique de traction, génératrice du prolongateur d'autonomie, composants d'électronique de puissance (T maximale à environ 60 à 70°C). Quand on indique que le fluide circule dans un circuit de refroidissement-chauffage d'un organe du véhicule, il peut s'agir d'une branche du circuit de l'organe et par exemple au moins une partie de circuit d'échangeur thermique d'un circuit de refroidissement- chauffage d'un organe du véhicule.  A second heat exchanger 1 1 as a cold source of the thermocouple device Seebeck effect receives a coolant, for example water 13 or air flowing arrows to various cooling-heating circuits of the vehicle, for example the cooling-heating circuit of the traction battery (maximum T at approximately 50 ° C.), the cooling-heating circuit 17 of the passenger compartment of the vehicle, the cooling circuit of the heat engine of the autonomy-extending device (T maximum at about 100-140 ° C) or alternatively (not shown) a cooling circuit of the electrotechnical components of the vehicle (electric traction motor, generator of the range extender, power electronics components (T max to approximately 60 to 70 ° C.) When it is indicated that the fluid circulates in a cooling-heating circuit of a body of the vehicle, it can be a branch of the circuit of the generator. ane and for example at least one heat exchanger circuit portion of a cooling-heating circuit of a vehicle member.
Le dispositif thermo générateur à effet Seebeck 7 est relié en outre par des câbles électriques 21 à un ensemble 23 de batterie de traction et divers accessoires électriques du véhicule qu'il peut alimenter en énergie électrique sélectivement suivant une puissance électrique comprise de 10 à 40 kW dans le cas d'un véhicule électrique, sous la consigne d'un dispositif de commande 25 du système manœuvré par le pilote (conducteur) du véhicule ou par un dispositif de pilotage automatique (calculateur). The thermocouple device Seebeck effect 7 is further connected by electric cables 21 to a set 23 of traction battery and various electrical accessories of the vehicle that can supply electrical energy selectively with an electric power of 10 to 40 kW in the case of an electric vehicle, under the command of a control device 25 of the system operated by the driver (driver) of the vehicle or by an automatic control device (computer).
Les circuits de refroidissement-chauffage 15, 17, 19 sont reliés en parallèle au circuit 26, 27 de la source froide, étant alimentés sélectivement chacun par une électrovanne 29 à trois voies montée à l'entrée de chaque circuit. Chacune des électrovannes 29 ouvre sur un circuit et ferme sur l'autre ou inversement, sous la commande du dispositif de commande. Eventuellement, l'électro vanne en amont du circuit peut fonctionner en synchronisme avec un élément clapet en aval du circuit (non représenté). Cet élément clapet peut empêcher toute introduction de fluide en aval du circuit lorsque l'électro vanne du circuit est fermée.  The cooling-heating circuits 15, 17, 19 are connected in parallel to the circuit 26, 27 of the cold source, each being fed selectively by a three-way solenoid valve 29 mounted at the inlet of each circuit. Each of the solenoid valves 29 opens on one circuit and closes on the other or vice versa, under the control of the control device. Optionally, the electro valve upstream of the circuit can operate in synchronism with a valve element downstream of the circuit (not shown). This valve element can prevent any introduction of fluid downstream of the circuit when the solenoid valve of the circuit is closed.
Sur la fig. 1 , le circuit 15 seul est ouvert.  In fig. 1, circuit 15 alone is open.
Ces circuits comportent chacun un capteur de la température 30 du fluide dans le circuit, relié au dispositif de commande 25 du système. Le dispositif 25 pilote l'ouverture ou la fermeture de chacune des électrovannes 29 à 3 voies des circuits et de même gère l'alimentation électrique de complément par le dispositif thermo- générateur de la batterie de traction ou des accessoires électriques 23 du véhicule selon une loi de pilotage du système, laquelle peut être sélectionnée manuellement par le pilote du véhicule ou de manière automatique par le dispositif de pilotage du véhicule.  These circuits each comprise a sensor of the temperature of the fluid in the circuit, connected to the control device 25 of the system. The device 25 controls the opening or closing of each of the three-way solenoid valves 29 of the circuits and likewise manages the complementary power supply by the thermo-generator device of the traction battery or of the electrical accessories 23 of the vehicle in accordance with a system control law, which can be selected manually by the driver of the vehicle or automatically by the vehicle control device.
Le fonctionnement du système est à présent décrit.  The operation of the system is now described.
Ainsi selon un pilotage du dispositif privilégiant le rendement énergétique, en ambiance froide, on peut accélérer la montée en température de la batterie de traction en ouvrant la vanne 29 de circuit correspondant 15, ce qui autorisera la circulation du fluide de la source froide dans ce circuit 15 et amènera ce fluide à être réchauffé par la source froide. Ce réchauffage augmentera la puissance et l'énergie disponible de la batterie et donc accroîtra les performances de vitesse et d'accélération du véhicule en ambiance froide.  Thus, according to a control of the device favoring energy efficiency, in a cold environment, it is possible to accelerate the rise in temperature of the traction battery by opening the corresponding circuit valve 15, which will allow the circulation of the fluid of the cold source in this case. circuit 15 and cause this fluid to be heated by the cold source. This heating will increase the power and available energy of the battery and therefore increase the speed and acceleration performance of the vehicle in a cold environment.
Parallèlement, l'énergie électrique fournie par le dispositif thermo générateur 7 peut alimenter le moteur de traction et d'autres accessoires électriques du véhicule, avec donc une réduction de la consommation électrique du véhicule par la batterie de traction seule. On peut encore commander le dispositif de commande 25 dans une consigne de confort de l'habitacle, en privilégiant l'alimentation du circuit de chauffage 17 de l'habitacle, notamment en ambiance froide, ce qui diminue la consommation des résistances électriques de chauffage de l'habitacle sur la batterie de traction. At the same time, the electrical energy supplied by the thermo generator device 7 can supply the traction motor and other electrical accessories of the vehicle, thus reducing the electrical consumption of the vehicle by the traction battery alone. It is still possible to control the control device 25 in a cabin comfort setting, by giving priority to feeding the heating circuit 17 of the passenger compartment, in particular in a cold environment, which reduces the consumption of the electric heating resistors of the passenger compartment. the cockpit on the traction battery.
De plus, la possibilité de basculer d'une source froide à une autre ou plusieurs autres permet d'augmenter l'écart de température entre la source chaude 9 et la source froide 1 1 (donc avec un meilleur rendement du thermo-générateur Seebeck) et laisse une large liberté pour les stratégies de pilotage. Ainsi, si la priorité est donnée au confort thermique de l'habitacle et à la montée en température du moteur thermique de générateur, alors c'est le liquide de refroidissement du moteur thermique qui sera connecté d'abord en priorité comme source froide, puis le circuit d'habitacle. Si la priorité est donnée à la montée en température de la batterie de traction afin d'augmenter les performances du véhicule en ambiance froide alors c'est le liquide de refroidissement de la batterie qui sera connecté en priorité comme source froide puis, lorsque la priorité a disparu, plusieurs circuits de refroidissement chauffage peuvent être alimentés simultanément par les électrovannes 29 en fonction des consigne de la commande de pilotage.  In addition, the possibility of switching from one cold source to another or several others makes it possible to increase the temperature difference between the hot source 9 and the cold source 1 1 (thus with a better efficiency of the Seebeck thermo-generator) and leaves a lot of freedom for the steering strategies. Thus, if priority is given to the thermal comfort of the passenger compartment and to the temperature rise of the generator engine, then it is the coolant of the engine that will first be connected first as a cold source, then the cockpit circuit. If the priority is given to the temperature rise of the traction battery to increase the performance of the vehicle in a cold environment then it is the coolant of the battery which will be connected in priority as a cold source then, when the priority has disappeared, several heating cooling circuits can be powered simultaneously by the solenoid valves 29 according to the setpoints of the control drive.
Il est à noter que certains des organes peuvent en outre être refroidis ou réchauffés par un autre circuit de refroidissement chauffage, par exemple monté en parallèle sur le circuit correspondant du système. Ainsi, on peut relier un circuit de chauffage 37 (par un radiateur électrique) sur le circuit 19 de moteur thermique et un circuit de chauffage analogue 39 sur le circuit 15 de batterie, voire sur le circuit de refroidissement chauffage des composants électrotechniques du véhicule (moteur électrique de traction, génératrice du prolongateur d'autonomie, composants d'électronique de puissance). Des thermostats 41 et 43 respectivement disposés sur ces circuits 37, 39 ouvrent ou ferment ces circuits en fonction des consignes de pilotage du système.  It should be noted that some of the members may further be cooled or heated by another heating cooling circuit, for example connected in parallel to the corresponding circuit of the system. Thus, it is possible to connect a heating circuit 37 (via an electric heater) to the heat engine circuit 19 and a similar heating circuit 39 to the battery circuit 15, or even to the heating circuit for heating the electrotechnical components of the vehicle ( electric traction motor, generator of range extender, power electronics components). Thermostats 41 and 43 respectively disposed on these circuits 37, 39 open or close these circuits according to the system control instructions.
Naturellement, selon le système 1 ' de la fig. 2 dans le cas de la variante de réalisation avec un système à dispositif thermo-générateur 7' à effet Seebeck avec un échangeur gaz-air, la source chaude 9' est constituée des gaz d'échappement du prolongateur d'autonomie et la source froide 1 1 ' est de l'air. Naturally, according to the system 1 'of FIG. 2 in the case of the variant embodiment with a Seebeck effect thermo-generator device system 7 'with a gas-air exchanger, the hot source 9' is consisting of the exhaust of the range extender and the cold source 1 1 'is air.

L'air puisé à l'extérieur 31 peut encore être acheminé par le ventilateur 34 et le clapet 29' au chauffage de la batterie 35 après être réchauffé dans l'échangeur 1 1 ' (si la batterie est refroidie par air).  The air drawn outside 31 can still be conveyed by the fan 34 and the valve 29 'to the heating of the battery 35 after being heated in the exchanger 1 1' (if the battery is cooled by air).
L'air puisé à l'extérieur 31 peut également être évacué en 31 ' à l'extérieur par le clapet 34 après avoir traversé l'échangeur 1 1 '. Dans ce cas, il n'y a pas de récupération thermique.  The air drawn outside 31 may also be discharged 31 'outside by the valve 34 after passing through the exchanger 11'. In this case, there is no heat recovery.
Les avantages du système restent les mêmes que dans le mode de réalisation de la fig. 1 en ce qui concerne la génération de courant électrique et la récupération de chaleur, notamment pour le chauffage de la batterie en ambiance froide et le chauffage de l'habitacle en ambiance froide.  The advantages of the system remain the same as in the embodiment of FIG. 1 with regard to the generation of electric current and heat recovery, in particular for heating the battery in a cold environment and heating the passenger compartment in a cold environment.
