AGENCEMENT POUR LE REFROIDISSEMENT D'UNE BATTERIE ARRANGEMENT FOR COOLING A BATTERY
DANS UN HABITACLE DE VEHICULE AUTOMOBILE IN A MOTOR VEHICLE HABITACLE
L'invention concerne un agencement pour le refroidissement d'une batterie dans un habitacle de véhicule automobile et notamment présente dans les véhicules de type électriques ou hybrides. The invention relates to an arrangement for cooling a battery in a passenger compartment of a motor vehicle and in particular present in vehicles of electric or hybrid type.
Il est admis que les véhicules électriques ou hybrides sont équipés d'une batterie composée d'éléments d'accumulateurs montés en série/parallèle dont la fonction principale est de fournir à la chaîne de traction l'énergie et la puissance nécessaire. It is accepted that electric or hybrid vehicles are equipped with a battery consisting of series / parallel accumulators whose main function is to provide the power train with the necessary power and power.
Les performances des batteries dépendent cependant fortement de leur température. En charge, cela se traduit, le plus souvent, par une perte de rendement ou par une interdiction de la charge si la température est trop élevée. En charge et en pause, une température de batterie trop élevée ou trop basse se traduit par une autodécharge importante voire une dégradation de la durée de vie et de l'autonomie. The performance of the batteries, however, strongly depend on their temperature. In charge, this usually results in a loss of efficiency or a prohibition of charging if the temperature is too high. When charging and paused, a battery temperature that is too high or too low results in a significant self-discharge or even a degradation of the service life and the autonomy.
Ainsi, il est nécessaire de prévoir un positionnement de la batterie dans l'habitacle adapté pour la ventiler au mieux afin d'éviter une température de fonctionnement trop élevée. Thus, it is necessary to provide a positioning of the battery in the passenger compartment adapted to ventilate the best to avoid a too high operating temperature.
A cet effet, il est connu de l'état de la technique que le refroidissement des batteries s'effectue grâce à l'air extérieur ou à l'air présent dans l'habitacle. For this purpose, it is known from the state of the art that the batteries are cooled by the outside air or the air present in the passenger compartment.
La publication JP 2001-233064 propose de refroidir une batterie positionnée sous les sièges arrière de véhicule grâce à l'air provenant de l'habitacle. Pour cela, selon un premier mode de réalisation de cette invention, l'air est introduit dans la batterie à partir d'une entrée d'air unique localisée en hauteur derrière les sièges arrière. Les conduits d'air se situent donc au niveau des oreilles des passagers arrière. Ceci est particulièrement gênant car ce système détériore le confort acoustique de l'utilisateur dû à la vitesse importante de l'air entrant dans le conduit. Un second mode de réalisation de l'invention est proposé dans cette publication. La batterie est positionnée sous les sièges arrière de véhicule. Elle dispose d'une entrée d'air localisée à proximité de l'un des côtés latéral du véhicule et d'une sortie d'air localisée à proximité de l'autre côté latéral du véhicule et s'évacuant dans la zone de chargement. Certes, ce mode de réalisation ne présente pas les inconvénients susmentionnés, cependant, le confort thermique des passagers est altéré puisqu'il existe une différence de température dans l'habitacle. En effet, le passager proche de l'entrée d'air bénéficiera d'une température plus basse que le passager proche du côté opposé de l'habitacle. Publication JP 2001-233064 proposes to cool a battery positioned under the rear seats of the vehicle thanks to the air coming from the passenger compartment. For this, according to a first embodiment of this invention, the air is introduced into the battery from a single air inlet located in height behind the rear seats. The air ducts are located at the ears of the rear passengers. This is particularly troublesome because this system deteriorates the acoustic comfort of the user due to the high speed of the air entering the duct. A second embodiment of the invention is proposed in this publication. The battery is positioned under the rear vehicle seats. It has an air intake located near one of the lateral sides of the vehicle and an air outlet located near the other side of the vehicle and evacuating in the loading area. Admittedly, this embodiment does not have the aforementioned drawbacks, however, the thermal comfort of passengers is impaired since there is a difference in temperature in the passenger compartment. Indeed, the passenger close to the air intake will benefit from a lower temperature than the passenger close to the opposite side of the passenger compartment.
L'invention vise à pallier ces inconvénients en proposant un agencement pour le refroidissement d'une batterie dans un habitacle de véhicule automobile amélioré. The invention aims to overcome these disadvantages by providing an arrangement for cooling a battery in an improved passenger car interior.
A cet effet, l'invention fournit un agencement d'au moins une batterie d'accumulateurs à bord d'un véhicule automobile comprenant au moins un siège disposé au dessus d'une surface de fixation qui délimite un passage pour la circulation d'un flux d'air dynamique sous le siège et vers l'arrière du véhicule caractérisé en ce que la batterie est disposée transversalement à l'arrière de ce siège en vis-à-vis du passage pour être refroidie par ledit flux d'air. For this purpose, the invention provides an arrangement of at least one accumulator battery on board a motor vehicle comprising at least one seat disposed above a fixing surface which delimits a passage for the circulation of a vehicle. dynamic air flow under the seat and towards the rear of the vehicle characterized in that the battery is disposed transversely to the rear of the seat vis-à-vis the passage to be cooled by said air flow.
Avantageusement, la batterie se trouve en partie sous le siège. Advantageously, the battery is partly under the seat.
De préférence, la batterie est logée dans un boîtier comprenant une face avant avec une ouverture d'admission d'air s'étendant sur la longueur transversale de l'habitacle et en vis-à-vis dudit passage. Preferably, the battery is housed in a housing comprising a front face with an air intake opening extending over the transverse length of the passenger compartment and vis-à-vis said passage.
Selon une caractéristique de l'invention, le boîtier comprend au moins une sortie pour le flux d'air. According to one characteristic of the invention, the housing comprises at least one outlet for the air flow.
Selon un mode de réalisation de l'invention, la surface de fixation est le plancher de l'habitacle. According to one embodiment of the invention, the attachment surface is the floor of the passenger compartment.
Selon un autre mode de réalisation de l'invention, le plancher de l'habitacle constitue la surface de fixation et la face avant du boîtier. According to another embodiment of the invention, the floor of the passenger compartment constitutes the fixing surface and the front face of the housing.
Selon encore un autre mode de réalisation de l'invention, la surface de fixation est un socle solidaire du plancher. According to yet another embodiment of the invention, the attachment surface is a base integral with the floor.
Avantageusement, la batterie est agencée à l'intérieur de l'habitacle. Advantageously, the battery is arranged inside the passenger compartment.
L'invention est maintenant décrite en référence aux dessins annexés, donnés à titre non limitatifs dans lesquels: - la figure 1 est une vue en perspective de l'agencement de l'invention selon un premier mode de réalisation, et - la figure 2 est une vue en coupe de l'agencement de l'invention selon un deuxième mode de réalisation. The invention is now described with reference to the accompanying drawings, given in a non-limiting manner in which: FIG. 1 is a perspective view of the arrangement of the invention according to a first embodiment, and FIG. a sectional view of the arrangement of the invention according to a second embodiment.
On définit les termes avant et arrière par rapport à la direction longitudinale du véhicule, l'avant désignant le sens de déplacement normal du véhicule, et l'arrière le sens opposé. The terms front and rear are defined with respect to the longitudinal direction of the vehicle, the front designating the normal direction of movement of the vehicle, and the rear the opposite direction.
La figure 1 représente un habitacle de véhicule automobile comprenant une banquette arrière 10 munie d'une assise 12 et d'un dossier 14 et une zone de chargement 16 à l'arrière de cette banquette 10. FIG. 1 shows a passenger compartment of a motor vehicle comprising a rear seat 10 provided with a seat 12 and a backrest 14 and a loading area 16 at the rear of this seat 10.
L'assise 12 est fixé par un moyen connu sur une surface de fixation 21 tel que le plancher 22 ou un socle 20 solidaire du plancher 22 de façon à laisser un passage 24 entre l'assise 12 et le socle 20 dont l'utilisation sera précisée plus tard dans la description. The seat 12 is fixed by a known means on a fastening surface 21 such as the floor 22 or a base 20 secured to the floor 22 so as to leave a passage 24 between the seat 12 and the base 20 whose use will be specified later in the description.
L'invention vise en particulier les véhicules électriques ou hybrides. En effet, ces derniers sont équipés d'une batterie 18 composée d'éléments d'accumulateurs montés en série/parallèle dont la fonction principale est de fournir à la chaîne de traction l'énergie et la puissance nécessaire. Cette batterie est le plus souvent positionnée dans un boîtier 30 permettant de la protéger et dans lequel un flux d'air 32 est apte à circuler pour permettre son refroidissement. Le flux d'air 32 provient de l'habitacle et plus précisément des ventilations présentes à l'avant des véhicules. The invention is particularly aimed at electric or hybrid vehicles. Indeed, the latter are equipped with a battery 18 composed of accumulator elements mounted in series / parallel whose main function is to provide the power train with the necessary energy and power. This battery is most often positioned in a housing 30 for protecting it and in which an air flow 32 is able to circulate to allow its cooling. The air flow 32 comes from the passenger compartment and specifically ventilations present at the front of the vehicles.
Ainsi, selon ce mode de réalisation de l'invention, le boîtier 30 de la batterie 18 s'étend longitudinalement selon un axe 26. Ce boîtier comprend une ouverture orientée vers l'avant du véhicule recouverte d'une grille d'admission d'air 28 et une sortie d'air pour son évacuation (non représentée). Le boîtier 30 est disposé transversalement dans l'habitacle à l'arrière de la banquette 10. Thus, according to this embodiment of the invention, the housing 30 of the battery 18 extends longitudinally along an axis 26. This housing comprises an opening facing the front of the vehicle covered with an intake grille of air 28 and an air outlet for its evacuation (not shown). The housing 30 is arranged transversely in the passenger compartment at the rear of the seat 10.
Le mérite de l'invention repose sur le fait que le flux d'air dynamique 32 circule entre le socle 20 et la banquette 10 dans le passage 24 et pénètre dans le boîtier 30 par la large ouverture faciale disposée en vis- à-vis de ce passage 24 afin de refroidir la batterie 18 de façon homogène sans dégrader, d'une part, le confort thermique car l'admission de l'air 32 s'effectue de façon uniforme et, d'autre part, le confort acoustique pour un utilisateur car l'admission de l'air 32 se situe dans la partie basse de l'habitacle. The merit of the invention is based on the fact that the dynamic air flow 32 flows between the base 20 and the seat 10 in the passage 24 and enters the housing 30 by the large face opening disposed opposite the this passage 24 to cool the battery 18 homogeneously without degrading, on the one hand, the thermal comfort because the admission of air 32 is performed uniformly and, on the other hand, the acoustic comfort for a user because the admission of air 32 is located in the lower part of the passenger compartment.
Selon un deuxième mode de réalisation de l'invention illustré sur la figure 2, le plancher 22 de l'habitacle constitue la surface de fixation 21 et la face avant du boîtier. Ainsi, l'ouverture faciale nécessaire pour l'admission d'air est présente sur le plancher 22. L'aspect esthétique de la zone de chargement 16 est ainsi améliorée. According to a second embodiment of the invention illustrated in Figure 2, the floor 22 of the passenger compartment constitutes the fastening surface 21 and the front face of the housing. Thus, the facial opening necessary for the admission of air is present on the floor 22. The aesthetic appearance of the loading area 16 is thus improved.
Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits, fournis à titre d'exemples illustratifs et non limitatifs. Notamment, la batterie peut se trouver dans une zone autre que la zone de chargement 16 du véhicule comme par exemple entre une première et une deuxième rangée de siège. Of course, the invention is not limited to the embodiments described, provided by way of illustrative and non-limiting examples. In particular, the battery may be in a zone other than the loading zone 16 of the vehicle, for example between a first and a second seat row.
