Description
1 DISPOSITIF ELECTRIQUE MULTIFONCTION La présente invention concerne de manière générale un dispositif électrique multifonction pour un véhicule automobile. De nos jours, les véhicules automobiles électriques ou hybrides sont de plus en plus répandus. En effet, leur émission réduite en matières polluantes et leur faible consommation de carburant fossile en fait des véhicules cibles privilégiées pour les consommateurs soucieux de leur environnement et de leur budget. Afin d'améliorer constamment ces véhicules, les moteurs électriques, les batteries et les différents circuits de charge de même que leur architecture ont été grandement améliorés. De manière générale, les véhicules électriques et hybrides comprennent un dispositif de charge de la batterie de véhicule. En effet, afin de recharger la batterie du véhicule il est nécessaire de la raccorder à une prise externe émettant une tension continue. Un tel dispositif de charge est connu comme comprenant entre autre un redresseur AC/DC incluant un transformateur afin de charger la batterie avec un courant à une tension prédéterminée. Egalement présent sur ce type de véhicule est un dispositif de conversion dit DC/DC qui permet à la batterie d'alimenter divers consommateurs électriques présents sur le véhicule. Un tel convertisseur comprend également un redresseur AC/DC et un transformateur, notamment.The present invention generally relates to a multifunctional electrical device for a motor vehicle. Nowadays, electric or hybrid motor vehicles are more and more widespread. In fact, their reduced emission of pollutants and their low fossil fuel consumption make them prime target vehicles for consumers concerned about their environment and their budget. In order to constantly improve these vehicles, electric motors, batteries and various load circuits as well as their architecture have been greatly improved. In general, electric and hybrid vehicles comprise a charging device for the vehicle battery. Indeed, in order to recharge the vehicle battery it is necessary to connect it to an external outlet emitting a DC voltage. Such a charging device is known as including among others an AC / DC rectifier including a transformer for charging the battery with a current at a predetermined voltage. Also present on this type of vehicle is a so-called DC / DC conversion device that allows the battery to power various electrical consumers present on the vehicle. Such a converter also comprises an AC / DC rectifier and a transformer, in particular.
Il est connu dans l'art antérieur que les véhicules automobiles électriques ou hybrides sont chers de part leurs composants intrinsèques et nécessitent une optimisation du poids toujours plus réduit notamment à cause du poids des batteries qui restent lourdes. Si le poids des batteries a été réduit avec les années, notamment en 25 abandonnant les piles à combustible, Il a également été nécessaire de trouver de nouveaux moyens pour réduire les coûts, le volume et le poids des composants électriques installés dans le véhicule.It is known in the prior art that electric or hybrid motor vehicles are expensive because of their intrinsic components and require an optimization of the weight always reduced especially because of the weight of the batteries which remain heavy. While the weight of the batteries has been reduced over the years, in particular by abandoning the fuel cells, it has also been necessary to find new ways to reduce the costs, the volume and the weight of the electrical components installed in the vehicle.
3036864 2 Par exemple, dans le document US 2009 103341 on décrit un dispositif de distribution de puissance dans un véhicule hybride comprenant différents convertisseurs AC/DC, DC/DC et une batterie. Ce dispositif peut fonctionner selon trois modes (recharge depuis une alimentation extérieure, 5 boost et recharge par réseau de bord). Dans ce dispositif on utilise un même composant dans les trois modes. Cependant ce dispositif propose une architecture servant à couvrir deux situations de vie à savoir une charge de la batterie via un convertisseur, un élément de commutation et un redresseur, et une alimentation du moteur via le convertisseur l'élément de commutation 10 et un onduleur. Cependant, ce dispositif est limité aux deux modes de fonctionnement et rajoute un dispositif, un commutateur, qui augmente le poids du véhicule. Egalement, dans le document WO 2014/180606 on décrit un dispositif de distribution de puissance dans un véhicule, dont l'architecture, c'est-à-dire 15 l'agencement et la connexion des organes, est tel qu'un courant extérieur peut être alimenté dans un convertisseur. Cependant ce dispositif ne résout pas le problème mentionné plus haut. Un but de la présente invention est donc de répondre aux inconvénients du document de l'art antérieur mentionné ci-dessus et en 20 particulier, tout d'abord, de fournir un dispositif électrique multifonction capable d'assumer une fonction d'alimentation et de recharge en minimisant son coût, son poids et son volume. Pour cela un premier aspect de l'invention concerne un dispositif électrique multifonction pour un véhicule comprenant un circuit de charge de batterie agencé pour raccorder une alimentation externe en courant alternatif présentant une première tension à une batterie du véhicule présentant une seconde tension, un circuit de conversion de courant agencé pour raccorder la batterie du véhicule présentant une seconde tension à des consommateurs électriques montés sur le véhicule, présentant une troisième tension, et un moyen de pilotage agencé pour piloter le dispositif selon un mode de recharge de la batterie ou un mode d'alimentation des 3036864 3 consommateurs électriques ou un mode charge et alimentation simultané regroupant les deux premiers modes, mode de charge de la batterie et d'alimentation simultanément, caractérisé en ce que le circuit de charge de batterie et le circuit de conversion de courant partagent un transformateur 5 commun réversible agencé pour être commuté par le moyen de pilotage de sorte à transformer la première tension en la seconde tension dans le mode de recharge et la seconde tension en la troisième tension dans le mode d'alimentation et enfin la première tension en la seconde et troisième tension simultanément dans le mode charge et alimentation simultané. De cette 10 manière, on mutualise les composants de deux dispositifs distincts afin d'obtenir un seul dispositif ayant les deux fonctions gagnant ainsi en coût, en volume et en poids. De manière avantageuse, le circuit de charge de batterie et le circuit de conversion de courant partagent en outre tous les composants entre le 15 transformateur et la batterie. Ainsi, on diminue les coûts et la complexité du dispositif. Une réalisation particulièrement intéressante consiste en ce que les composants partagés comprennent des MOS . De cette manière, il peut avoir différentes fonctions.For example, in US 2009 103341 describes a power distribution device in a hybrid vehicle comprising different AC / DC converters, DC / DC and a battery. This device can operate in three modes (charging from an external power supply, 5 boost and charging by the onboard network). In this device, the same component is used in the three modes. However, this device proposes an architecture for covering two life situations namely a charge of the battery via a converter, a switching element and a rectifier, and a supply of the motor via the converter switching element 10 and an inverter. However, this device is limited to both modes of operation and adds a device, a switch, which increases the weight of the vehicle. Also, in WO 2014/180606 there is described a device for distributing power in a vehicle, whose architecture, that is to say the arrangement and connection of the organs, is such that an external current can be fed into a converter. However this device does not solve the problem mentioned above. An object of the present invention is therefore to meet the drawbacks of the document of the prior art mentioned above and in particular, first of all, to provide a multifunction electrical device capable of assuming a function of feeding and recharge by minimizing its cost, weight and volume. For this purpose, a first aspect of the invention relates to a multifunction electrical device for a vehicle comprising a battery charging circuit arranged for connecting an external AC power supply having a first voltage to a battery of the vehicle having a second voltage, a circuit of current conversion arranged to connect the battery of the vehicle having a second voltage to vehicle-mounted electrical consumers having a third voltage, and control means arranged to drive the device in a battery charging mode or a battery mode. power supply of the electric consumers or a mode simultaneous charging and powering combining the first two modes, charging mode of the battery and supply simultaneously, characterized in that the battery charging circuit and the current conversion circuit share a reversible common transformer 5 arranged to r be switched by the driving means so as to transform the first voltage into the second voltage into the charging mode and the second voltage into the third voltage into the power mode and finally the first voltage into the second and third voltage simultaneously in the charge and simultaneous power mode. In this way, the components of two separate devices are pooled to obtain a single device having both functions thus gaining in cost, volume and weight. Advantageously, the battery charging circuit and the current converting circuit further share all the components between the transformer and the battery. Thus, the costs and the complexity of the device are reduced. A particularly interesting realization is that the shared components include MOS. In this way, it can have different functions.
20 Avantageusement, les MOS sont agencés pour être configuré par le moyen de pilotage de sorte à présenter une fonction de pont de diode en mode de recharge et en mode charge et alimentation en simultané et une fonction d'onduleur en mode d'alimentation. Ainsi, les différents modes de fonctionnement sont exécutés de manière fiable.Advantageously, the MOS are arranged to be configured by the driving means so as to have a diode bridge function in charging mode and in simultaneous charge and power mode and an inverter function in power mode. Thus, the different modes of operation are executed reliably.
25 De manière avantageuse, le transformateur comprend un premier enroulement basse tension agencé pour être raccordé à l'alimentation externe, un second enroulement basse tension raccordé à la batterie et un enroulement très basse tension raccordé aux consommateurs. De cette manière, le transformateur est simple à fabriquer.Advantageously, the transformer comprises a first low voltage winding arranged to be connected to the external power supply, a second low voltage winding connected to the battery and a very low voltage winding connected to the consumers. In this way, the transformer is simple to manufacture.
3036864 4 Une réalisation particulièrement intéressante consiste en ce que la tension des enroulements basse tension est comprise dans la plage de 170 V et 500 V et la tension de l'enroulement très basse tension est comprise dans la plage de 6 à 18 V. Ainsi, le dispositif peut être utilisé avec une large 5 variété d'équipements. Avantageusement, le dispositif électrique comprend en outre des moyens de refroidissement communs aux deux circuits. De cette manière, on diminue encore les coûts et la complexité du dispositif. De manière avantageuse, la première tension est de 230 V ou 110V, 10 la deuxième tension est comprise entre 170 V et 500 V et la troisième tension est comprise entre 6 V et 18 V. Ainsi, on peut brancher le dispositif sur une prise secteur conventionnelle. Une réalisation particulièrement intéressante consiste en ce que le dispositif électrique comprend également un microprocesseur commun aux 15 deux circuits. De cette manière, on diminue encore plus les coûts et la complexité du dispositif. Un second aspect de l'invention est un véhicule comprenant un dispositif électrique selon le premier aspect de l'invention. D'autres caractéristiques et avantages de la présente invention 20 apparaîtront plus clairement à la lecture de la description détaillée qui suit d'un mode de réalisation de l'invention donné à titre d'exemple nullement limitatif et illustré par le dessin annexé, dans lequel : - la figure 1 représente un diagramme schématique du dispositif électrique de la présente invention.A particularly interesting embodiment is that the voltage of the low voltage windings is in the range of 170 V and 500 V and the voltage of the very low voltage winding is in the range of 6 to 18 V. Thus, the device can be used with a wide variety of equipment. Advantageously, the electrical device further comprises cooling means common to both circuits. In this way, the costs and complexity of the device are further reduced. Advantageously, the first voltage is 230 V or 110 V, the second voltage is between 170 V and 500 V and the third voltage is between 6 V and 18 V. Thus, the device can be connected to a mains socket. conventional. A particularly interesting embodiment is that the electrical device also comprises a microprocessor common to both circuits. In this way, the costs and complexity of the device are further reduced. A second aspect of the invention is a vehicle comprising an electrical device according to the first aspect of the invention. Other features and advantages of the present invention will appear more clearly on reading the following detailed description of an embodiment of the invention given by way of non-limiting example and illustrated by the appended drawing, in which: FIG. 1 represents a schematic diagram of the electrical device of the present invention.
