Description
La présente invention concerne un système de branchement de chargeur embarqué de batterie de traction d’un véhicule automobile hybride, avec faisceaux reliés par un boîtier de jonction, ainsi qu’un véhicule automobile hybride comprenant un tel système de branchement.The present invention relates to a connection system for an on-board traction battery charger of a hybrid motor vehicle, with harnesses connected by a junction box, as well as a hybrid motor vehicle comprising such a connection system.
Un type de véhicule électrique connu, présenté notamment par le document US-A1-20210323417, comporte une batterie d’alimentation d’une machine électrique de traction reliée par un faisceau à un chargeur embarqué de charge lente, appelé « on board charger » en langue anglaise, « OBC » en abrégé.One type of known electric vehicle, presented in particular by the document US-A1-20210323417, includes a power supply battery for an electric traction machine connected by a harness to an on-board slow charger, called "on board charger" in English, "OBC" for short.
Lors du stationnement du véhicule le chargeur embarqué est branché par un câble à un réseau extérieur de distribution d’électricité du type domestique, délivrant un courant alternatif avec une puissance limitée, pour redresser ce courant afin de recharger la batterie avec un courant continu et une tension adaptée.When the vehicle is parked, the on-board charger is connected by a cable to an external domestic-type electricity distribution network, delivering alternating current with limited power, to rectify this current in order to recharge the battery with direct current and an appropriate voltage.
D’une manière générale les véhicules hybrides comportent une batterie de traction de petite capacité qui permet de stocker une énergie électrique lors des freinages pour la restituer lors des accélérations suivantes. Cette petite batterie permet aussi un roulage limité en mode électrique.Generally speaking, hybrid vehicles have a small-capacity traction battery that stores electrical energy during braking and releases it during subsequent acceleration. This small battery also allows for limited driving in electric mode.
De manière connue on ajoute sur certains véhicules hybrides un chargeur embarqué de charge lente, du type OBC, afin de recharger la batterie de traction lors des stationnements pour améliorer la part de roulage électrique.As is known, some hybrid vehicles add an on-board slow charger, of the OBC type, to recharge the traction battery when parked to improve the proportion of electric driving.
En particulier, le chargeur embarqué peut comporter un premier faisceau électrique délivrant le courant de ce chargeur présentant une faible puissance, qui présente des câbles comprenant une section réduite adaptée à cette puissance limitée.In particular, the on-board charger may include a first electrical harness delivering the current from this low-power charger, which has cables with a reduced cross-section adapted to this limited power.
Par ailleurs il est connu de réaliser une famille de véhicules hybrides comportant une batterie de traction commune comprenant un faisceau électrique de forte puissance directement branché sur cette batterie, disposant de câbles présentant une grande section de passage de courant adaptée pour cette puissance élevée, et d’ajouter sur certains véhicules de cette famille un chargeur embarqué de charge lente.Furthermore, it is known to produce a family of hybrid vehicles with a common traction battery including a high-power electrical harness directly connected to this battery, with cables having a large current passage cross-section suitable for this high power, and to add on some vehicles of this family an on-board slow charging charger.
Pour les véhicules de cette famille comportant le chargeur embarqué, on doit prévoir un raccordement électrique entre le premier faisceau amont de faible puissance et le deuxième faisceau aval de forte puissance, qui pose des problèmes de réalisation d’un boîtier de jonction entre les câbles présentant des sections très différentes, tout en assurant à la fois une facilité de mise en œuvre dans un espace réduit pour obtenir un boîtier de petite dimension, et une protection efficace contre les court-circuits afin d’assurer la sécurité.For vehicles in this family with an on-board charger, an electrical connection must be provided between the first upstream low-power harness and the second downstream high-power harness, which poses problems in the realization of a junction box between cables with very different cross-sections, while ensuring both ease of implementation in a small space to obtain a small box, and effective protection against short circuits to ensure safety.
La présente invention a notamment pour but d’éviter ces problèmes de l’art antérieur.The present invention aims in particular to avoid these problems of the prior art.
Elle propose à cet effet un système de branchement de chargeur embarqué de batterie de traction d’un véhicule automobile hybride, comprenant un premier faisceau de câbles vers la batterie présentant une première section de passage du courant, un deuxième faisceau de câbles vers le chargeur avec une section de passage plus petite, et un boîtier de jonction entre eux, ce système de branchement étant remarquable en ce que le boîtier comporte des plots intérieurs de liaison électrique comprenant deux plots d’entrée recevant des câbles du deuxième faisceau, disposés suivant une première ligne et une deuxième ligne sensiblement parallèle en face de deux plots de sortie recevant des câbles du premier faisceau, comporte sur la première ligne une barrette principale reliant le plot d’entrée au plot de sortie, et comporte sur une troisième ligne sensiblement parallèle un fusible fixé entre deux plots intermédiaires qui sont reliés chacun par une barrette intermédiaire au plot d’entrée et au plot de sortie de la deuxième ligne.It proposes for this purpose a connection system for an on-board traction battery charger of a hybrid motor vehicle, comprising a first bundle of cables to the battery having a first current passage cross-section, a second bundle of cables to the charger with a smaller passage cross-section, and a junction box between them, this connection system being remarkable in that the box has internal electrical connection terminals comprising two input terminals receiving cables from the second bundle, arranged in a first line and a second substantially parallel line opposite two output terminals receiving cables from the first bundle, has on the first line a main bar connecting the input terminal to the output terminal, and has on a third substantially parallel line a fuse fixed between two intermediate terminals which are each connected by an intermediate bar to the input terminal and the output terminal of the second line.
Un avantage de ce système de branchement est qu’il permet de recevoir dans le même boîtier de jonction avec des plots similaires présentant des procédés de montage identiques, des cosses des câbles avec grandes sections pour une forte puissance, celles des câbles avec section plus petite pour une puissance plus faible, les barrettes et le fusible qui assure la sécurité.One advantage of this connection system is that it allows the same junction box to accommodate, with similar terminals and identical mounting methods, cable lugs with large cross-sections for high power, cable lugs with smaller cross-sections for lower power, busbars and the fuse that ensures safety.
On obtient une facilité d’assemblage dans un boîtier compact comprenant les six plots utilisant une même technologie, permettant d’assurer de manière simple et rapide, avec un outillage similaire, toutes les liaisons internes ainsi que les liaisons externes avec les cosses des câbles.Easy assembly is achieved in a compact housing comprising the six studs using the same technology, allowing all internal connections as well as external connections with cable lugs to be made simply and quickly with similar tools.
Le système de branchement selon l’invention peut comporter de plus une ou plusieurs des caractéristiques suivantes, qui peuvent être combinées entre elles.The branching system according to the invention may further include one or more of the following features, which may be combined with each other.
Avantageusement, chaque plot comporte une vis recevant un écrou de serrage d’un câble ou d’une barrette.Advantageously, each terminal has a screw that receives a nut for tightening a cable or a bar.
Dans ce cas, avantageusement chaque câble comporte à son extrémité une cosse présentant un perçage engagé sur la vis du plot.In this case, advantageously each cable has at its end a lug with a hole engaged on the screw of the stud.
Avantageusement, suivant la direction des lignes parallèles les plots d’entrée et les plots de sortie présentent entre eux une distance inférieure à celle entre les plots intermédiaires.Advantageously, along the direction of the parallel lines, the entry and exit points have a shorter distance between them than between the intermediate points.
Avantageusement, chaque câble entre dans le boîtier en passant au travers d’un dispositif d’étanchéité comprenant un anneau en élastomère qui le serre.Advantageously, each cable enters the housing by passing through a sealing device comprising an elastomer ring that clamps it.
En particulier, les câbles du deuxième faisceau peuvent présenter une section de passage du courant de 6mm².In particular, the cables of the second bundle may have a current passage cross-section of 6mm².
En particulier, les câbles du premier faisceau peuvent présenter une section de passage du courant compris entre 30 et 120mm².In particular, the cables of the first bundle may have a current passage cross-section of between 30 and 120mm².
L’invention a aussi pour objet un véhicule automobile hybride équipé d’un chargeur embarqué de batterie de traction, remarquable en ce que ce chargeur embarqué est relié à la batterie de traction par un système de branchement comprenant l’une quelconque des caractéristiques précédentes.The invention also relates to a hybrid motor vehicle equipped with an on-board traction battery charger, remarkable in that this on-board charger is connected to the traction battery by a connection system comprising any one of the preceding characteristics.
L’invention a de plus pour objet une famille de véhicules automobiles comprenant la caractéristique précédente, remarquable en ce qu’elle comporte sur certains véhicules des premiers faisceaux de câbles présentant des sections de passage du courant qui sont différentes entre ces véhicules.The invention also relates to a family of motor vehicles comprising the preceding characteristic, remarkable in that it includes on certain vehicles the first cable bundles having current passage sections which are different between these vehicles.
L’invention sera mieux comprise et d’autres caractéristiques et avantages apparaîtront plus clairement à la lecture de la description ci-après donnée à titre d’exemple, en référence aux dessins annexés dans lesquels :The invention will be better understood and other features and advantages will become more apparent upon reading the following description given by way of example, with reference to the accompanying drawings in which:
La
Un système de branchement reliant la batterie 2 au chargeur embarqué 8 comporte un connecteur électrique 12 branché sur cette batterie, un premier faisceau de câble 10 prévu pour transmettre une forte puissance, comprenant deux câbles de section importante, un boîtier de jonction 14, et un deuxième faisceau de câbles 16 prévu pour transmettre une petite puissance qui est délivrée par le chargeur embarqué 8, comprenant deux câbles de section plus petite.A connection system linking the battery 2 to the on-board charger 8 includes an electrical connector 12 connected to this battery, a first cable bundle 10 intended to transmit a high power, comprising two cables of large cross-section, a junction box 14, and a second cable bundle 16 intended to transmit a small power which is delivered by the on-board charger 8, comprising two cables of smaller cross-section.
Le boîtier de jonction 14 comporte deux liaisons reliant les deux câbles des deux faisceaux 10, 16 entre eux, avec une protection sur une de ces liaisons.The junction box 14 has two connections linking the two cables of the two bundles 10, 16 together, with protection on one of these connections.
En particulier le premier faisceau 10 peut comporter des câbles présentant une section de 35 mm², ou plus importante comme 70, 90 ou 120 mm², prévue pour passer des courants importants sur certaines versions des véhicules.In particular, the first bundle 10 may include cables with a cross-section of 35 mm², or larger such as 70, 90 or 120 mm², designed to carry significant currents on certain versions of the vehicles.
Afin de conserver un même type de batterie de traction 2 avec son premier faisceau 10 attaché, sur une famille de véhicules hybrides comprenant des variantes, on prévoit un premier faisceau standard qui est unique sur toutes ces variantes. De cette manière la production et la gestion d’un même type de batterie de traction 2 avec son premier faisceau standard 10 permet de rationaliser cet approvisionnement et de réduire les coûts.To maintain a consistent traction battery type 2 with its attached first harness 10 across a family of hybrid vehicles with variants, a standard first harness is used across all variants. This streamlines the supply chain and reduces costs by producing and managing the same traction battery type 2 with its standard first harness 10.
Pour la variante de véhicule comportant le chargeur de batterie embarqué 8 ajouté dans le coffre, on prévoit le deuxième faisceau 16 disposant de câbles avec une petite section qui est suffisante pour la puissance délivrée par ce chargeur, afin d’alimenter directement le premier faisceau 10 grâce au boîtier de jonction 14.For the vehicle variant with the added on-board battery charger 8 in the trunk, the second harness 16 is provided with cables of a small cross-section which is sufficient for the power delivered by this charger, in order to directly power the first harness 10 via the junction box 14.
Les figures 2 et 3 présentent le boîtier de jonction plat 14 comportant une boîte parallélépipédique ouverte en façade 20, disposant au dos d’une plaque 22 allongée suivant une direction longitudinale, comprenant à l’arrière des dispositifs de fixation sur le véhicule. Chaque extrémité de la plaque comporte un perçage recevant un anneau 28 de maintien d’une extrémité du premier 10 ou du deuxième faisceau 16 qui arrive sur une paroi du côté 30 de la boîte 20.Figures 2 and 3 show the flat junction box 14 comprising a parallelepiped-shaped box 20 with an open front, having on its rear an elongated plate 22 extending along a longitudinal direction, and including on the rear mounting devices for attaching to the vehicle. Each end of the plate has a hole receiving a ring 28 for retaining one end of the first 10 or the second bundle 16 which connects to a wall on the side 30 of the box 20.
Chaque paroi de côté 30 comporte deux perçages recevant chacun un dispositif d’étanchéité 32 pour un câble 52 traversant cette paroi. Un couvercle 34 fermant la face avant du fond 20 avec une étanchéité, permet d’intervenir dans le boîtier 14 pour effectuer les raccordements des câbles 52.Each side wall 30 has two holes, each receiving a sealing device 32 for a cable 52 passing through that wall. A cover 34, sealing the front face of the base 20, allows access to the housing 14 for connecting the cables 52.
L’intérieur du fond de la boîte 20 comporte six plots 40 comprenant chacun une vis disposée perpendiculairement à ce fond, recevant un écrou 42 de serrage des cosses 44 disposées aux extrémités des câbles 52, des barrettes conductrices plates 46, 48 ou d’un fusible 50.The inside of the bottom of the box 20 has six studs 40, each containing a screw arranged perpendicularly to this bottom, receiving a nut 42 for tightening the lugs 44 arranged at the ends of the cables 52, the flat conductive strips 46, 48 or a fuse 50.
De cette manière l’ensemble des fixations dans le boîtier 14 devant assurer une tenue mécanique, résistante aux vibrations en particulier, ainsi qu’une connexion électrique fiable dans le temps et assurée par une même technologie. La procédure de montage identique pour tous les plots 40 comporte la disposition des éléments à fixer sur chaque plot en engageant un perçage de l’élément sur la vis du plot, puis le serrage d’un écrou 42 facilement accessible par la face avant ouverte du boîtier, qui serre l’ensemble des éléments disposés sur le même plot.In this way, all the fixings in the housing 14 must ensure mechanical strength, particularly resistance to vibrations, as well as a reliable electrical connection over time, all ensured by the same technology. The identical assembly procedure for all the pads 40 involves arranging the elements to be fixed on each pad by engaging a hole in the element with the pad's screw, then tightening a nut 42, easily accessible from the open front of the housing, which secures all the elements arranged on the same pad.
Les plots 40 sont alignés par paires suivant trois lignes parallèles, successivement A, B, C, disposées suivant la direction longitudinale. Face au deuxième faisceau 16, sur les deux premières lignes A, B deux petits plots d’entrée 40A1, 40B1 reçoivent chacun une cosse de petite section 44 fixée au bout d’un câble 52 de ce deuxième faisceau. Face au premier faisceau 10, deux grands plots de sortie 40A2, 40B2 reçoivent chacun une cosse de grande section 44 fixée au bout d’un câble 52 de ce premier faisceau.The lugs 40 are aligned in pairs along three parallel lines, successively A, B, C, arranged in the longitudinal direction. Opposite the second bundle 16, on the first two lines A, B, two small input lugs 40A1, 40B1 each receive a small cross-section terminal 44 fixed to the end of a cable 52 of this second bundle. Opposite the first bundle 10, two large output lugs 40A2, 40B2 each receive a large cross-section terminal 44 fixed to the end of a cable 52 of this first bundle.
Sur la première ligne parallèle A une barrette principale plate 46 relie le petit plot d’entrée 40A1 au grand plot de sortie 40A2 disposé en face pour permettre un passage direct du courant électrique vers un premier pôle de la batterie 2.On the first parallel line A a main flat bar 46 connects the small input pin 40A1 to the large output pin 40A2 arranged opposite to allow a direct passage of the electric current to a first pole of the battery 2.
Sur la deuxième ligne parallèle B chaque plot 40B1, 40B2 reçoit une barrette plate intermédiaire 48 pour le relier à un plot 40C1, 40C2 disposé à côté sur la troisième ligne parallèle C. Les deux plots 40C1, 40C2 de la troisième ligne parallèle C sont reliés entre eux par un fusible 50. On obtient pour le deuxième pôle de la batterie 2 un passage du courant sécurisé par le fusible 50 disposé en série entre le pôle d’entrée 40B1 et le pôle de sortie 40B2.On the second parallel line B, each terminal 40B1, 40B2 receives an intermediate flat strip 48 to connect it to a terminal 40C1, 40C2 located next to it on the third parallel line C. The two terminals 40C1, 40C2 of the third parallel line C are connected together by a fuse 50. For the second terminal of battery 2, a current passage is secured by the fuse 50 located in series between the input terminal 40B1 and the output terminal 40B2.
Suivant la direction longitudinale les plots d’entrée 40A1, 40B1 et les plots de sortie 40A2, 40B2 présentent entre eux une distance inférieure à celle entre les plots intermédiaires 40C1, 40C2.Following the longitudinal direction the input pads 40A1, 40B1 and the output pads 40A2, 40B2 have a distance between them that is less than that between the intermediate pads 40C1, 40C2.
On obtient un boîtier 14 compact, présentant les cosses 44 des câbles 52 des deux faisceaux 10, 16 disposées proches l’une de l’autre permettant d’avoir un boîtier court dans cette direction grâce au fusible 54 qui est reporté latéralement sur le côté en utilisant la troisième ligne parallèle C.We obtain a compact box 14, presenting the lugs 44 of the cables 52 of the two bundles 10, 16 arranged close together allowing to have a short box in this direction thanks to the fuse 54 which is moved laterally on the side using the third parallel line C.
Le fusible 50 reste facilement accessible par l’ouverture du couvercle de boîtier 34, puis par un dévissage des deux écrous 42 de ce fusible pour le changer. De cette manière en cas de rupture du fusible 50 l’opération est rapide à effectuer.Fuse 50 remains easily accessible by opening the cover of the housing 34, then unscrewing the two nuts 42 of this fuse to replace it. In this way, in the event of a blown fuse 50, the operation is quick to perform.

Pour chaque câble 52 le bloc d’entrée 60 comporte un réceptacle de forme cylindrique contenant un anneau en élastomère 68 traversé par le câble, puis un capuchon 66 qui serre axialement l’anneau afin d’obtenir par cette compression un serrage latéral qui assure l’étanchéité autour du câble.For each cable 52 the input block 60 includes a cylindrical receptacle containing an elastomer ring 68 through which the cable passes, then a cap 66 which axially tightens the ring in order to obtain by this compression a lateral tightening which ensures the seal around the cable.
En cas d’utilisation de différents diamètres de câbles 52, en particulier pour les câbles de forte puissance du premier faisceau 10, il suffit de modifier les diamètres de l’anneau en élastomère 68 pour obtenir de manière simple et économique un ajustement à ce diamètre.In the case of use of different cable diameters 52, in particular for the high power cables of the first bundle 10, it is sufficient to modify the diameters of the elastomer ring 68 to obtain a simple and economical adjustment to this diameter.
