La présente invention concerne un dispositif de régulation thermique d'un module de batteries pour véhicule automobile. The present invention relates to a device for thermal regulation of a battery module for a motor vehicle.
Certains véhicules, de type hybride, comprennent une motorisation comportant un moteur d'entraînement thermique et une machine électrique permettant d'alterner des configurations de fonctionnement en modes thermique et électrique. Certain vehicles, of the hybrid type, include a motorization comprising a thermal drive motor and an electric machine making it possible to alternate operating configurations in thermal and electric modes.
La machine électrique est alimentée par un module de batteries. Le bon fonctionnement de ces batteries dépend de la température de l'air environnant le module notamment de la température ambiante à l'extérieur du véhicule. The electric machine is powered by a battery module. The proper functioning of these batteries depends on the temperature of the air surrounding the module, in particular the ambient temperature outside the vehicle.
On a donc proposé dans l'état de la technique un dispositif de régulation thermique d'un module de batteries pour véhicule automobile, du type comprenant des moyens de mise en circulation d'un flux d'air à travers le module de batteries. It has therefore been proposed in the prior art a thermal regulation device for a battery module for a motor vehicle, of the type comprising means for circulating an air flow through the battery module.
Habituellement, l'air circulant à travers le module de batteries provient de l'habitacle du véhicule. Usually, the air flowing through the battery module comes from inside the vehicle.
En saison froide, lorsque par exemple la température des batteries est voisine de-18 OC, les réactions chimiques dans les batteries sont inhibées ce qui empêche ces dernières de délivrer la puissance électrique nécessaire au bon fonctionnement de la machine électrique. Il convient donc de faire démarrer le moteur thermique de façon à élever la température des batteries jusqu'à environ 5 C. Une fois cette température atteinte, les batteries sont en mesure de délivrer la puissance nécessaire électrique au bon fonctionnement de la motorisation. In the cold season, when for example the temperature of the batteries is close to -18 OC, the chemical reactions in the batteries are inhibited which prevents the latter from delivering the electric power necessary for the proper functioning of the electric machine. It is therefore necessary to start the engine in order to raise the temperature of the batteries to around 5 C. Once this temperature is reached, the batteries are able to deliver the necessary electrical power for the proper functioning of the engine.
Toutefois, lorsque la température des batteries est inférieure à -18 DC, le démarrage du véhicule, même par l'intermédiaire du moteur thermique, n'est pas envisageable car les batteries ne sont pas en mesure de délivrer la puissance électrique nécessaire pour alimenter les moyens de pilotage de la boîte de vitesses électrique équipant généralement le véhicule hybride. However, when the temperature of the batteries is lower than -18 DC, starting the vehicle, even via the internal combustion engine, is not possible since the batteries are not able to deliver the electrical power necessary to supply the control means of the electric gearbox generally equipping the hybrid vehicle.
En saison chaude, le flux d'air provenant de l'habitacle, relativement froid, circule à travers le module de batteries en permettant ainsi de limiter la température de ces batteries à environ 55 C. In the hot season, the air flow from the relatively cold passenger compartment circulates through the battery module, thereby limiting the temperature of these batteries to around 55 C.
Lorsque la température des batteries est supérieure à 55DC leur sollicitation doit être réduite pour ne pas affecter leur durée de vie. When the temperature of the batteries is higher than 55DC, their stress must be reduced so as not to affect their lifespan.
L'invention a pour but d'optimiser le fonctionnement et la durée de vie du module de batteries. The object of the invention is to optimize the operation and the service life of the battery module.
A cet effet, l'invention a pour objet un dispositif de régulation thermique, du type précité, caractérisé en ce qu'il comprend une enceinte, formant des moyens de guidage du flux d'air, dans laquelle sont logés le module de batteries et des moyens de régulation thermique du flux d'air. To this end, the subject of the invention is a thermal regulation device, of the aforementioned type, characterized in that it comprises an enclosure, forming means for guiding the air flow, in which the battery module is housed and means for thermal regulation of the air flow.

Ce dispositif 10 est destiné à réguler la température d'un module classique 12 de batteries pour véhicule automobile, notamment de type hybride comprenant une motorisation comportant un moteur d'entraînement thermique et une machine électrique permettant d'alterner des configurations de fonctionnement en modes thermique et électrique. This device 10 is intended to regulate the temperature of a conventional module 12 of batteries for a motor vehicle, in particular of the hybrid type comprising a motorization comprising a thermal drive motor and an electric machine making it possible to alternate operating configurations in thermal modes and electric.
Le module 12 comprend en général plusieurs éléments formant batterie mais pourrait le cas échéant n'en comprendre qu'un seul. The module 12 generally comprises several battery elements but could if necessary include only one.
Le dispositif 10 comprend une enceinte 14 qui, dans ce premier mode de réalisation de l'invention, est fermée de façon étanche à l'air. The device 10 comprises an enclosure 14 which, in this first embodiment of the invention, is closed in an airtight manner.
Le module 12 de batteries est logé dans l'enceinte 14. Cette dernière forme des moyens de guidage pour un flux d'air circulant en circuit fermé à l'intérieur de l'enceinte 14. Le flux d'air est schématisé par des flèches F sur la figure 1. On notera que le flux d'air F circule à travers le module 12 de batteries de façon à réguler sa température. The battery module 12 is housed in the enclosure 14. The latter forms guide means for an air flow circulating in a closed circuit inside the enclosure 14. The air flow is shown diagrammatically by arrows F in FIG. 1. It will be noted that the air flow F circulates through the module 12 of batteries so as to regulate its temperature.
La température de l'air du flux F est réglée à l'aide de moyens 16 de régulation thermique du flux d'air logés à l'intérieur de l'enceinte 14. The temperature of the air in the flow F is adjusted by means 16 of thermal regulation of the air flow housed inside the enclosure 14.
Les moyens de régulation thermique 16 comprennent un échangeur thermique 18 liquide caloporteur/air. Cet échangeur thermique 18 est raccordé à un circuit de liquide caloporteur dont on a représenté des branches amont 20 et aval 22 raccordées à l'échangeur thermique 18. Le liquide caloporteur est de type classique et comprend, par exemple, de l'eau qui, le cas échéant, est mélangée à un antigel. The thermal regulation means 16 comprise a heat exchanger 18 heat transfer liquid / air. This heat exchanger 18 is connected to a circuit of heat transfer liquid of which there have been shown upstream 20 and downstream 22 branches connected to the heat exchanger 18. The heat transfer liquid is of conventional type and comprises, for example, water which, if necessary, is mixed with an antifreeze.
Un ventilateur classique 24, logé dans l'enceinte 14, est destiné à entraîner le flux d'air F à travers l'échangeur thermique 18. A conventional fan 24, housed in the enclosure 14, is intended to drive the air flow F through the heat exchanger 18.
De préférence, les moyens de régulation thermique 16 comprennent également des moyens de chauffage 26, par exemple des moyens électriques destinés à chauffer le flux d'air par effet Joule. Ces moyens électriques de chauffage 26 comprennent, par exemple, une thermistance classique, notamment de type CTP (Coefficient de Température Positif), utilisée dans une plage de fonctionnement telle que la puissance délivrée par la thermistance diminue lorsque la température augmente. De préférence, la puissance fournit par les moyens électriques de chauffage 26 est de l'ordre de 1 kW. Preferably, the thermal regulation means 16 also comprise heating means 26, for example electrical means intended to heat the air flow by the Joule effect. These electrical heating means 26 comprise, for example, a conventional thermistor, in particular of the PTC (Positive Temperature Coefficient) type, used in an operating range such that the power delivered by the thermistor decreases when the temperature increases. Preferably, the power supplied by the electrical heating means 26 is of the order of 1 kW.
Une paroi 28, séparant le module 12 de batteries des moyens 16 de régulation thermique, participe à la canalisation du flux d'air F à travers ce module 12 et ces moyens de régulation thermique 16. A wall 28, separating the battery module 12 from the thermal regulation means 16, participates in the channeling of the air flow F through this module 12 and these thermal regulation means 16.
De préférence, des moyens de régulation de la pression de l'air circulant dans l'enceinte 14 sont logés dans cette dernière. Preferably, means for regulating the pressure of the air flowing in the enclosure 14 are housed in the latter.
<Desc/Clms Page number 4> <Desc / Clms Page number 4>
Les moyens de régulation de pression comprennent, par exemple, des moyens classiques 30 de compensation de pression pilotés par un capteur 32 de pression. The pressure regulation means comprise, for example, conventional pressure compensation means 30 controlled by a pressure sensor 32.
Le module 12 de batteries étant généralement susceptible de dégager de l'hydrogène, des moyens classiques 34 d'absorption d'hydrogène sont logés dans l'enceinte 14. Since the battery module 12 is generally capable of producing hydrogen, conventional means 34 for absorbing hydrogen are housed in the enclosure 14.
On décrira ci-dessous les principaux aspects du fonctionnement du dispositif de régulation thermique 10 liés à l'invention. The main aspects of the operation of the thermal regulation device 10 related to the invention will be described below.
En saison froide, lorsque la température des batteries est voisine de -18OC, le module 12 de batteries est réchauffé à l'aide des moyens de chauffage 26. L'air, contenu dans l'enceinte 14, est entraîné par le ventilateur 24 à travers les moyens électriques de chauffage 26. Le flux d'air chauffé traverse le module 12 de batteries de façon à élever la température de ces batteries jusqu'à environ 5 C. In the cold season, when the temperature of the batteries is close to -18 ° C., the battery module 12 is heated using the heating means 26. The air, contained in the enclosure 14, is driven by the fan 24 to through the electrical heating means 26. The flow of heated air passes through the battery module 12 so as to raise the temperature of these batteries to around 5 C.
Le flux d'air chauffé par les moyens de chauffage 26 permet aux batteries du module 12 d'atteindre rapidement une température pour laquelle elles sont susceptibles de délivrer une puissance électrique suffisante permettant une activation de la motorisation hybride ou électrique pure sans contrainte indésirable sur les batteries. The flow of air heated by the heating means 26 allows the batteries of the module 12 to quickly reach a temperature for which they are capable of delivering sufficient electrical power allowing activation of the hybrid or pure electric motorization without undesirable stress on the batteries.
Le cas échéant, l'échangeur thermique 18 liquide caloporteur/air peut participer au chauffage du flux d'air. A cet effet, des moyens classiques 36 de chauffage du liquide caloporteur sont agencés dans la branche amont 20 du circuit de liquide caloporteur. Ces moyens 36 de chauffage peuvent être disposés à l'extérieur ou à l'intérieur de l'enceinte 14. If necessary, the heat exchanger 18 heat transfer liquid / air can participate in the heating of the air flow. To this end, conventional means 36 for heating the heat transfer liquid are arranged in the upstream branch 20 of the heat transfer liquid circuit. These heating means 36 can be arranged outside or inside the enclosure 14.
Les moyens 36 de chauffage du liquide caloporteur peuvent être utilisés en combinaison avec les moyens 26 de chauffage de l'air ou bien peuvent remplacer ces moyens de chauffage 26. The means 36 for heating the heat-transfer liquid can be used in combination with the means 26 for heating the air or can replace these heating means 26.
En saison chaude, le flux d'air F, traversant l'échangeur thermique 18, permet de refroidir le module 12 de batteries de façon à maintenir la température de ce module 12 en-dessous d'un seuil garantissant une durée de vie optimale des batteries. Ce seuil est par exemple d'environ 45 C. Le refroidissement du flux d'air F est réalisé par transfert, via l'échangeur 18, de frigories provenant du liquide caloporteur, relativement froid, vers le flux d'air F circulant dans l'enceinte 14. In hot season, the air flow F, passing through the heat exchanger 18, makes it possible to cool the module 12 of batteries so as to keep the temperature of this module 12 below a threshold guaranteeing an optimal lifetime of the batteries. This threshold is for example around 45 C. The cooling of the air flow F is carried out by transfer, via the exchanger 18, of frigories coming from the relatively cool heat-transfer liquid to the air flow F circulating in the pregnant 14.
On a représenté sur la figure 2 un dispositif de régulation thermique selon un second mode de réalisation de l'invention. Sur cette figure, les éléments analogues à ceux de la figure 1 sont désignés par des références identiques. FIG. 2 shows a thermal regulation device according to a second embodiment of the invention. In this figure, elements similar to those of Figure 1 are designated by identical references.

Dans ce cas, l'enceinte 14 est raccordée à des moyens de mise en circulation d'air provenant de l'habitacle ou de l'extérieur du véhicule. Ainsi, l'air du flux F guidé dans l'enceinte 14 provient de l'extérieur de l'enceinte 14. In this case, the enclosure 14 is connected to means for circulating air coming from the passenger compartment or from outside the vehicle. Thus, the air from the flow F guided into the enclosure 14 comes from outside the enclosure 14.
Les moyens de mise en circulation de l'air extérieur à l'enceinte 14 comprennent notamment une première ouverture 38, ménagée à travers la paroi de l'enceinte, formant une entrée d'air provenant de l'extérieur de l'enceinte 14, et une seconde ouverture 40, ménagée à travers la paroi de l'enceinte 14, formant une sortie d'air vers l'extérieur de l'enceinte 14. The means for circulating the air outside the enclosure 14 comprise in particular a first opening 38, formed through the wall of the enclosure, forming an air inlet coming from the outside of the enclosure 14, and a second opening 40, formed through the wall of the enclosure 14, forming an air outlet to the outside of the enclosure 14.
Les entrée 38 et sortie 40 d'air sont disposées respectivement en amont de l'échangeur thermique 18 et en aval du module 12 de batteries en considérant le sens de circulation du flux F. The air inlet 38 and outlet 40 are arranged respectively upstream of the heat exchanger 18 and downstream of the battery module 12, considering the direction of flow of the flow F.
Dans le second mode de réalisation de l'invention, il n'y a pas de risque de surpression de l'air ni d'accumulation d'hydrogène dans l'enceinte 14 si bien que les moyens de régulation de pression 30,32 et d'absorption d'hydrogène 34 ne sont pas nécessaires. In the second embodiment of the invention, there is no risk of air overpressure or accumulation of hydrogen in the enclosure 14 so that the pressure regulation means 30, 32 and absorption of hydrogen 34 is not necessary.
Parmi les avantages de l'invention, on notera que celle-ci permet d'optimiser le fonctionnement et la durée de vie du module 12 de batteries. Among the advantages of the invention, it will be noted that it makes it possible to optimize the operation and the service life of the module 12 of batteries.
En effet, en saison froide, le flux d'air chauffé, circulant à travers le module 12 de batteries permet d'élever rapidement la température de ces batteries jusqu'à une valeur permettant un bon fonctionnement de la machine électrique. Par rapport à l'état de la technique, la durée de montée en température des batteries (par exemple de-18 C à +5 C) peut être réduite d'environ 40%. In fact, in the cold season, the flow of heated air circulating through the module 12 of batteries makes it possible to quickly raise the temperature of these batteries to a value allowing proper operation of the electric machine. Compared to the state of the art, the duration of temperature rise of the batteries (for example from −18 ° C. to + 5 ° C.) can be reduced by approximately 40%.
En saison chaude, le flux d'air F, refroidi par l'échangeur thermique 18, permet de réduire si nécessaire la température du module 12 de batteries de façon à la stabiliser à une valeur garantissant une durée de vie relativement longue des batteries. In hot season, the air flow F, cooled by the heat exchanger 18, makes it possible to reduce the temperature of the battery module 12 if necessary, so as to stabilize it at a value guaranteeing a relatively long lifespan of the batteries.
L'invention permet donc de satisfaire les besoins électriques d'un véhicule automobile pour une température ambiante à l'extérieur du véhicule comprise dans un intervalle plus important que celui permis par un module de batteries ne bénéficiant pas de l'invention. The invention therefore makes it possible to satisfy the electrical needs of a motor vehicle for an ambient temperature outside the vehicle comprised in a greater interval than that permitted by a battery module not benefiting from the invention.
On notera que la structure de l'enceinte est relativement indépendante de celle du module de batteries ce qui favorise la standardisation. Note that the structure of the enclosure is relatively independent from that of the battery module, which promotes standardization.
Dans le cas du premier mode de réalisation de l'invention, l'enceinte 14 est isolée de l'habitacle si bien que la régulation thermique du module 12 de batteries est relativement indépendante de la température de l'habitacle. Par ailleurs, l'enceinte 14 n'étant pas raccordée à des moyens de mise en circulation d'air provenant de l'habitacle, In the case of the first embodiment of the invention, the enclosure 14 is isolated from the passenger compartment so that the thermal regulation of the battery module 12 is relatively independent of the temperature of the passenger compartment. Furthermore, the enclosure 14 not being connected to means for circulating air coming from the passenger compartment,

le dispositif 10 peut être plus facilement standardisé pour s'adapter facilement à différents modèles de véhicule. the device 10 can be more easily standardized to easily adapt to different vehicle models.
