Description

BATTERIE A CELLULES REFROIDIES PAR DES PLAQUES DE REFROIDISSEMENT  BATTERY WITH CELLS COOLED BY COOLING PLATES
EN CONFIGURATION DE RADIATEUR  IN RADIATOR CONFIGURATION
[0001] La présente invention concerne une batterie à cellules refroidies par des plaques de refroidissement, la batterie adoptant une configuration en radiateur pour la disposition des éléments constitutifs de la batterie les uns par rapport aux autres. The present invention relates to a cell battery cooled by cooling plates, the battery adopting a radiator configuration for the arrangement of the components of the battery with respect to each other.
[0002] Aujourd'hui, il existe trois types de cellules qui sont les cellules prismatiques, les cellules cylindriques et les cellules dites de poussée. Pour ces trois types de cellules, la technique d’assemblage est toujours similaire. On assemble une petite quantité de cellules qu'on regroupe dans un module puis on assemble ces modules avec un système de refroidissement et, pour finir, on assemble le tout dans un assemblage formant la batterie. Today, there are three types of cells which are prismatic cells, cylindrical cells and so-called thrust cells. For these three cell types, the assembly technique is always similar. We assemble a small quantity of cells which we group in a module then we assemble these modules with a cooling system and, finally, we assemble everything in an assembly forming the battery.
[0003] Le premier problème majeur de cette solution est son encombrement puisqu’il est prévu toute une structure qui entoure un petit groupe de cellules. Cette structure prend du volume et, avec les contraintes liées à l'assemblage qui imposent d'avoir un jeu entre les modules, il se produit une forte limitation de la quantité de cellules que l'on peut embarquer dans un ensemble batterie. The first major problem with this solution is its size, since a whole structure is provided which surrounds a small group of cells. This structure takes volume and, with the constraints linked to the assembly which impose to have a play between the modules, there occurs a strong limitation of the quantity of cells which one can embark in a battery assembly.
[0004] Le deuxième problème se situe sur l'aspect du refroidissement où l'on n'a que très peu de contact entre les cellules et le système de refroidissement, en général des plaques de refroidissement, ce qui est dû principalement à la structure des modules. The second problem lies in the aspect of cooling where there is very little contact between the cells and the cooling system, generally cooling plates, which is mainly due to the structure modules.
[0005] Ceci peut être vu à la lumière de la figure 1. La figure 1 montre une batterie 1a conformée selon l’état de la technique. Cette batterie 1 a comprend des plaques 2 de refroidissement, des cellules 3a, 3b, 3c, 3d productrices d’un courant électrique et des barres d’assemblage 4 des cellules 3a, 3b, 3c, 3d ainsi qu’un collecteur d’entrée 5 et un collecteur de sortie 6 de liquide de refroidissement circulant dans les plaques 2 de refroidissement. La batterie 1 a montre une structure externe 8 entourant la batterie 1 a ainsi que des éléments de renforcement 9 internes à la batterie 1 a. This can be seen in the light of Figure 1. Figure 1 shows a battery 1a shaped according to the state of the art. This battery 1 a includes cooling plates 2, cells 3a, 3b, 3c, 3d producing an electric current and assembly bars 4 of cells 3a, 3b, 3c, 3d as well as an input collector. 5 and a coolant outlet manifold 6 circulating in the cooling plates 2. The battery 1 a shows an external structure 8 surrounding the battery 1 a as well as reinforcing elements 9 internal to the battery 1 a.
[0006] Le document US-A-2011/162820 décrit une batterie avec une plaque de refroidissement et une pluralité de cellules. La plaque de refroidissement comprend une ailette de refroidissement avec une surface sensiblement plane. La plaque de refroidissement comprend un cadre contigu à l'ailette de refroidissement et formant un joint avec l'ailette de refroidissement adjacente au périmètre de celle-ci. Le cadre et l'ailette de refroidissement définissent au moins une entrée de fluide, au moins une sortie de fluide et un canal d'écoulement entre celles-ci. Document US-A-2011/162820 describes a battery with a cooling plate and a plurality of cells. The cooling plate includes a cooling fin with a substantially planar surface. The cooling plate comprises a frame contiguous to the cooling fin and forming a seal with the cooling fin adjacent to the perimeter of the latter. The frame and the cooling fin define at least one fluid inlet, at least one fluid outlet and a flow channel therebetween.
[0007] L'entrée de fluide et la sortie de fluide sont disposées à travers le joint et sont en communication fluidique avec le canal d'écoulement. Le canal d'écoulement est disposé à proximité du périmètre et en communication de transfert de chaleur avec la surface sensiblement plane de l'ailette de refroidissement. The fluid inlet and the fluid outlet are arranged through the seal and are in fluid communication with the flow channel. The flow channel is disposed near the perimeter and in heat transfer communication with the substantially planar surface of the cooling fin.
[0008] Ce document ne décrit cependant pas comment sont positionnées les cellules par rapport aux plaques de refroidissement et notamment l’attribution d’un nombre de cellules par plaque de refroidissement. This document does not however describe how the cells are positioned relative to the cooling plates and in particular the allocation of a number of cells per cooling plate.
[0009] Par conséquent, le problème à la base de l’invention est pour une batterie comprenant des cellules, des barres d’assemblage et des plaques de refroidissement entre un collecteur d’entrée et un collecteur de sortie, de disposer au moins ces éléments les uns par rapport aux autres, afin d’augmenter le nombre de cellules intégrées dans la batterie tout en leur assurant un refroidissement optimal. Therefore, the problem underlying the invention is for a battery comprising cells, assembly bars and cooling plates between an inlet manifold and an outlet manifold, to have at least these elements in relation to each other, in order to increase the number of cells integrated in the battery while ensuring optimal cooling.
[0010] Pour atteindre cet objectif, il est prévu selon l’invention une batterie comprenant des plaques de refroidissement, des cellules productrices d’un courant électrique et des barres d’assemblage des cellules, ainsi qu’un collecteur d’entrée et un collecteur de sortie de liquide de refroidissement circulant dans les plaques de refroidissement. L’invention se distingue par le fait que les plaques de refroidissement sont réparties en plusieurs rangées parallèles, chaque rangée s’étendant du collecteur d’entrée vers le collecteur de sortie, deux cellules étant associées à une plaque de refroidissement entre chaque paire de deux barres d’assemblage adjacentes, les deux cellules s’étendant parallèlement à la plaque de refroidissement associée. To achieve this objective, there is provided according to the invention a battery comprising cooling plates, cells producing an electric current and cell assembly bars, as well as an input collector and a coolant outlet manifold circulating in the cooling plates. The invention is distinguished by the fact that the cooling plates are distributed in several parallel rows, each row extending from the inlet manifold to the outlet manifold, two cells being associated with a cooling plate between each pair of two adjacent assembly bars, the two cells extending parallel to the associated cooling plate.
[0011] L’effet technique est de supprimer la structure externe et les éléments de renforcement internes à la batterie qui prennent une place conséquente. L’assemblage de la batterie se fait en analogie avec celui du radiateur. Les ailettes d'un radiateur sont formées par les cellules, les plaques de refroidissement deviennent les structures du radiateur et les collecteurs deviennent les traverses et longerons de la batterie. The technical effect is to remove the external structure and the internal reinforcing elements of the battery which take up a significant amount of space. The battery is assembled in analogy to that of the radiator. The fins of a radiator are formed by the cells, the cooling plates become the structures of the radiator and the collectors become the cross members and side members of the battery.
[0012] La solution proposée par la présente invention permet d'intégrer de 20 à 30% de cellules en plus, donc d’augmenter la capacité de la batterie. Le refroidissement se fait directement sur les cellules et par de plus grandes surfaces de contact, ce qui permet d'accepter un cycle de recharge de batterie rapide, inférieur à 20 minutes et dissipant une grande énergie thermique. The solution proposed by the present invention allows to integrate 20 to 30% more cells, therefore increasing the capacity of the battery. The cooling is done directly on the cells and by larger contact surfaces, which allows accept a fast battery recharge cycle, less than 20 minutes and dissipating great thermal energy.
[0013] Une telle batterie est résistante et supporte des chocs ou des vibrations, ce qui la rend particulièrement appropriée à être embarquée à bord d’un véhicule automobile. Une telle batterie peut contribuer à rigidifier le châssis du véhicule. Such a battery is resistant and withstands shock or vibration, which makes it particularly suitable for being loaded on board a motor vehicle. Such a battery can help stiffen the chassis of the vehicle.
[0014] L'invention est applicable à tout type de cellules et peut aussi être associée à des modifications comme rajout de conducteurs thermiques, comme des pattes thermiques entre cellules et plaques de refroidissement. The invention is applicable to any type of cell and can also be associated with modifications such as adding thermal conductors, such as thermal tabs between cells and cooling plates.
[0015] Avantageusement, les cellules sont réparties en rangées parallèles aux rangées de plaques de refroidissement avec deux cellules intercalées entre deux rangées de plaques de refroidissement adjacentes. Advantageously, the cells are distributed in rows parallel to the rows of cooling plates with two cells interposed between two rows of adjacent cooling plates.
[0016] Avantageusement, les extrémités de la plaque de refroidissement de chaque rangée sont soudées ou brasées ou de préférence serties avec le collecteur d’entrée ou le collecteur de sortie. [0017] En effet, le sertissage ne chauffe pas les cellules et permet de les préserver. Advantageously, the ends of the cooling plate of each row are welded or brazed or preferably crimped with the inlet manifold or the outlet manifold. In fact, the crimping does not heat the cells and makes it possible to preserve them.
[0018] Avantageusement, les barres d’assemblage s’étendent parallèlement aux collecteurs d’entrée et de sortie en étant perpendiculaires aux plaques de refroidissement et aux cellules.

[0025] D’autres caractéristiques, buts et avantages de la présente invention apparaîtront à la lecture de la description détaillée qui va suivre et au regard des dessins annexés donnés à titre d’exemples non limitatifs et sur lesquels : Other characteristics, objects and advantages of the present invention will appear on reading the detailed description which follows and with regard to the appended drawings given by way of nonlimiting examples and in which:
- la figure 1 est une représentation schématique d’une batterie selon l’état de la technique,  - Figure 1 is a schematic representation of a battery according to the state of the art,
- la figure 2 est une représentation schématique d’une batterie selon la présente invention.  - Figure 2 is a schematic representation of a battery according to the present invention.
[0026] Il est à garder à l’esprit que les figures sont données à titre d'exemples et ne sont pas limitatives de l’invention. Elles constituent des représentations schématiques de principe destinées à faciliter la compréhension de l’invention et ne sont pas nécessairement à l'échelle des applications pratiques. En particulier, les dimensions des différents éléments illustrés ne sont pas représentatives de la réalité. It should be borne in mind that the figures are given by way of examples and are not limitative of the invention. They constitute schematic representations of principle intended to facilitate the understanding of the invention and are not necessarily at the scale of practical applications. In particular, the dimensions of the various elements illustrated are not representative of reality.
[0027] Aux figures 1 et 2, il n’est référencé, pour simplification, qu’une seule barre d’assemblage 4, un seul orifice 7, une seule plaque de refroidissement 2 et deux cellules 3a, 3b associées sur toutes les deux cellules associées mais ce qui est énoncé pour un de ces éléments l’est pour tous les éléments équivalents. In Figures 1 and 2, it is referenced, for simplicity, only one assembly bar 4, a single orifice 7, a single cooling plate 2 and two cells 3a, 3b associated on both associated cells but what is stated for one of these elements is stated for all equivalent elements.
[0028] En se référant à la figure 2, la présente invention concerne une batterie 1 comprenant des plaques 2 de refroidissement, des cellules 3a, 3b, 3c, 3d productrices d’un courant électrique et des barres d’assemblage 4 ainsi qu’un collecteur d’entrée 5 et un collecteur de sortie 6 de liquide de refroidissement, avantageusement mais pas uniquement à base d’eau, circulant dans les plaques 2 de refroidissement, comme le montrent les flèches. Referring to Figure 2, the present invention relates to a battery 1 comprising cooling plates 2, cells 3a, 3b, 3c, 3d producing an electric current and assembly bars 4 as well as an inlet manifold 5 and an outlet manifold 6 of coolant, advantageously but not only water-based, circulating in the cooling plates 2, as shown by the arrows.
[0029] Selon la présente invention, les plaques 2 de refroidissement sont réparties en plusieurs rangées parallèles. Chaque rangée s’étend du collecteur d’entrée 5 vers le collecteur de sortie 6 afin d’assurer une circulation de liquide de refroidissement dans la batterie 1. According to the present invention, the cooling plates 2 are distributed in several parallel rows. Each row extends from the inlet manifold 5 to the outlet manifold 6 in order to ensure circulation of coolant in the battery 1.
[0030] Deux cellules 3a, 3b, avantageusement des cellules 3a, 3b, 3c, 3d électrochimiques de stockage et de restitution d’énergie électrique, sont associées à une plaque 2 de refroidissement entre chaque paire de deux barres d’assemblage 4 adjacentes, le mot adjacent étant pris dans le sens de consécutif. Les deux cellules 3a, 3b s’étendent parallèlement à la plaque 2 de refroidissement associée. Two cells 3a, 3b, advantageously cells 3a, 3b, 3c, 3d electrochemical storage and restitution of electrical energy, are associated with a cooling plate 2 between each pair of two assembly bars 4 adjacent, the word adjacent being taken in the sense of consecutive. The two cells 3a, 3b extend parallel to the associated cooling plate 2.
[0031] Dans cet exemple, les barres d’assemblage 4 sont positionnées sur l’une des deux tranches de chaque plaque 2 de refroidissement, mais d’autres architectures sont envisageables. In this example, the assembly bars 4 are positioned on one of the two sections of each cooling plate 2, but other architectures are possible.
[0032] Comme montré à la figure 2 entre la barre d’assemblage 4 la plus proche du collecteur d’entrée 5 et le collecteur d’entrée 5, il peut être intercalé une seule et unique cellule 3d. Ceci peut valoir entre la barre d’assemblage 4 la plus proche du collecteur de sortie 6 et le collecteur de sortie 6 avec une cellule 3c. As shown in Figure 2 between the assembly bar 4 closest to the inlet manifold 5 and the inlet manifold 5, it can be interposed with a single 3d cell. This can be true between the assembly bar 4 closest to the outlet manifold 6 and the outlet manifold 6 with a cell 3c.
[0033] Les cellules 3a, 3b, 3c, 3d peuvent être réparties en rangées parallèles aux rangées de plaques 2 de refroidissement avec deux cellules 3a, 3b intercalées entre deux rangées de plaques 2 de refroidissement adjacentes ou consécutives. A deux cellules 3a, 3b est donc dédiée une portion d’une plaque 2 de refroidissement et ainsi de suite pour la rangée formée par la plaque 2 de refroidissement. The cells 3a, 3b, 3c, 3d can be distributed in rows parallel to the rows of cooling plates 2 with two cells 3a, 3b interposed between two rows of adjacent or consecutive cooling plates 2. To two cells 3a, 3b is therefore dedicated a portion of a cooling plate 2 and so on for the row formed by the cooling plate 2.
[0034] A la figure 2, il y a 15 plaques 2 de refroidissement, 4 barres d’assemblage 4 et 8 cellules 3a, 3b, 3c, 3d entre deux rangées adjacentes de plaques 2 de refroidissement, c’est-à-dire au total 14 fois 8 cellules 3a, 3b, 3c, 3d soient 112 cellules 3a, 3b, 3c, 3d. Les rangées de cellules 3a, 3b, 3c, 3d et les rangées de plaques 2 de refroidissement s’étendent dans la longueur de la batterie 1. Tout ceci n’est pas limitatif. In Figure 2, there are 15 cooling plates 2, 4 assembly bars 4 and 8 cells 3a, 3b, 3c, 3d between two adjacent rows of cooling plates 2, that is to say in total 14 times 8 cells 3a, 3b, 3c, 3d or 112 cells 3a, 3b, 3c, 3d. The rows of cells 3a, 3b, 3c, 3d and the rows of cooling plates 2 extend in the length of the battery 1. All of this is not limiting.
[0035] Les extrémités de la plaque 2 de refroidissement de chaque rangée peuvent être soudées ou brasées ou serties avec le collecteur d’entrée 5 ou le collecteur de sortie 6 afin que le circuit de liquide de refroidissement soit étanche et fermé. The ends of the cooling plate 2 of each row can be welded or brazed or crimped with the inlet manifold 5 or the outlet manifold 6 so that the coolant circuit is sealed and closed.
[0036] Les barres d’assemblage 4 peuvent s’étendre parallèlement aux collecteurs d’entrée 5 et de sortie 6 en étant perpendiculaires aux plaques 2 de refroidissement et aux cellules 3a, 3b, 3c, 3d. La batterie 1 présente alors une section carrée ou rectangulaire. A la figure 2, ce sont les largeurs d’une batterie 1 de section rectangulaire qui portent chacune un collecteur d’entrée 5 ou de sortie de liquide de refroidissement. The assembly bars 4 can extend parallel to the inlet 5 and outlet 6 manifolds being perpendicular to the cooling plates 2 and to the cells 3a, 3b, 3c, 3d. The battery 1 then has a square or rectangular section. In FIG. 2, these are the widths of a battery 1 of rectangular section which each carry an inlet manifold 5 or outlet for coolant.
[0037] Pour chaque paire de deux barres d’assemblage 4 adjacentes, lesdites deux barres d’assemblage 4 adjacentes peuvent être positionnées pour effectuer une mise sous pression des paires de deux cellules 3a, 3b et des portions des plaques 2 de refroidissement intercalées entre les deux barres d’assemblage 4 adjacentes. [0038] A la figure 2, les barres d’assemblage 4 s’étendent dans la largeur de la batterie 1 en créant une contrainte sur les cellules 3a, 3b, 3c, 3d et la portion de plaque 2 de refroidissement intercalées entre deux barres d’assemblage 4 pour un renforcement du contact entre lesdites deux cellules 3a, 3b et la portion de la plaque 2 de refroidissement For each pair of two adjacent assembly bars 4, said two adjacent assembly bars 4 can be positioned to pressurize the pairs of two cells 3a, 3b and portions of the cooling plates 2 interposed between the two adjacent assembly bars 4. In Figure 2, the assembly bars 4 extend in the width of the battery 1 creating a constraint on the cells 3a, 3b, 3c, 3d and the portion of cooling plate 2 interposed between two bars assembly 4 for strengthening the contact between said two cells 3a, 3b and the portion of the cooling plate 2
[0039] Comme il peut être vu à la figure 2, les cellules 3a, 3b, 3c, 3d ayant chacune un évent de dégazage, les barres de liaisond’assemblage 4 peuvent être percées d’orifices 7 d’aération, avantageusement périodiquement répartis en correspondance des évents de dégazage. Par exemple, dans le mode de réalisation montré à la figure 2, chaque orifice 7 d’aération d’une barre d’assemblage 4 peut être aligné avec une rangée de cellules 3a, 3b, 3c, 3d. A la figure 2, il est donc montré 14 orifices 7 d’aération par barre d’assemblage 4, donc autant d’orifices 7 d’aération que de paires de deux cellules 3a, 3b. Les orifices 7 permettent ainsi l’échappement de gaz lorsque les cellules 3a, 3b, 3c, 3d sont en surpression consécutivement à une surchauffe. As can be seen in Figure 2, the cells 3a, 3b, 3c, 3d each having a degassing vent, the connection rods 4 can be pierced with ventilation holes 7, advantageously periodically distributed in correspondence with the degassing vents. For example, in the embodiment shown in FIG. 2, each ventilation opening 7 of an assembly bar 4 can be aligned with a row of cells 3a, 3b, 3c, 3d. In FIG. 2, 14 ventilation holes 7 are therefore shown per assembly bar 4, therefore as many ventilation holes 7 as pairs of two cells 3a, 3b. The orifices 7 thus allow the escape of gas when the cells 3a, 3b, 3c, 3d are in overpressure following an overheating.
[0040] Pour les deux barres d’assemblage les plus extrêmes avec chacune de ces deux barres d’assemblage d’extrémité faisant face à distance à un collecteur d’entrée 5 ou un collecteur de sortie 6, il peut aussi être prévu un orifice 7 d’aération faisant face pour chaque seule et unique cellule 3c, 3d faisant face au collecteur d’entrée 5 ou au collecteur de sortie 6 dans chaque rangée de cellules 3a, 3b, 3c, 3d. For the two most extreme assembly bars with each of these two end assembly bars facing away from an inlet manifold 5 or an outlet manifold 6, there may also be an orifice 7 facing ventilation for each single cell 3c, 3d facing the inlet manifold 5 or the outlet manifold 6 in each row of cells 3a, 3b, 3c, 3d.
[0041] En leur intérieur, les plaques 2 de refroidissement peuvent comprendre plusieurs canaux de liquide de refroidissement, avantageusement à surface plane. Inside, the cooling plates 2 may comprise several channels of coolant, advantageously with a flat surface.
[0042] La présente invention concerne un véhicule automobile comprenant au moins une telle batterie 1 , par exemple soit une batterie 1 de réseau de bord ou soit une batterie 1 de traction alimentant un moteur électrique, la taille et le nombre de cellules 3a, 3b, 3c, 3d étant différentes dans ces deux cas. The present invention relates to a motor vehicle comprising at least one such battery 1, for example either a battery 1 of on-board network or a traction battery 1 supplying an electric motor, the size and the number of cells 3a, 3b , 3c, 3d being different in these two cases.
[0043] L’invention n’est nullement limitée aux modes de réalisation décrits et illustrés qui n’ont été donnés qu’à titre d’exemples. The invention is in no way limited to the embodiments described and illustrated which have been given only by way of examples.
