Description
L’invention concerne une batterie de secours pour la charge de la batterie d’alimentation électrique du moteur d’un véhicule automobile, ainsi qu’un procédé de charge au moyen d’une telle batterie.The invention relates to an emergency battery for charging the electrical supply battery of the engine of a motor vehicle, as well as to a method of charging by means of such a battery.
La contrainte principale de déploiement des véhicules électriques est l’autonomie des batteries qu’ils embarquent, et donc la possibilité pour l’utilisateur de pouvoir recharger son véhicule au sein d’un réseau de bornes fixes qui soit suffisamment dense pour ne pas risquer une immobilisation due à une décharge complète de la batterie.The main constraint for the deployment of electric vehicles is the autonomy of the batteries they carry, and therefore the possibility for the user to be able to recharge his vehicle within a network of fixed terminals which is dense enough not to risk a immobilization due to a complete discharge of the battery.
Ce problème est d’autant plus critique que l’indicateur d’autonomie des véhicules électriques demeure fortement fluctuant, notamment en fonction du profil du déplacement et des conditions extérieures, ce qui ne donne pas suffisamment confiance à l’utilisateur pour qu’il utilise la capacité quasi complète des batteries.This problem is all the more critical in that the range indicator for electric vehicles fluctuates greatly, in particular depending on the travel profile and external conditions, which does not give the user enough confidence to use almost full capacity of the batteries.
L’invention vise à résoudre ce problème en proposant une batterie de secours qui permet à l’utilisateur, notamment en cas de décharge complète de la batterie d’un véhicule électrique, de bénéficier de façon autonome et en toute sécurité d’une autonomie supplémentaire pouvant notamment lui permettre de rallier une borne de recharge.The invention aims to solve this problem by proposing an emergency battery which allows the user, in particular in the event of complete discharge of the battery of an electric vehicle, to benefit autonomously and in complete safety from additional autonomy. which can in particular allow him to reach a charging station.
A cet effet, selon un premier aspect, l’invention propose une batterie de secours pour la charge de la batterie d’alimentation électrique du moteur d’un véhicule automobile, ladite batterie de secours comprenant un boîtier dans lequel est conditionné un pack comprenant au moins une pile électrique qui est inerte avant activation et qui, après activation, délivre une charge électrique unitaire donnée, ledit boîtier intégrant également un dispositif de connexion du pack de piles à un système de type BMS de la batterie d’alimentation électrique du moteur d’un véhicule automobile et un module de communication et d’activation de chacune des piles, ledit module comprenant des moyens d’activation d’au moins une pile en fonction d’un critère d’acceptabilité de la charge unitaire par la batterie du véhicule.To this end, according to a first aspect, the invention proposes an emergency battery for charging the electrical supply battery of the engine of a motor vehicle, said emergency battery comprising a box in which is packaged a pack comprising at at least one electric battery which is inert before activation and which, after activation, delivers a given unit electric charge, said box also incorporating a device for connecting the battery pack to a BMS-type system of the electric power supply battery of the motor d a motor vehicle and a communication and activation module for each of the batteries, said module comprising means for activating at least one battery as a function of a criterion of acceptability of the unit charge by the battery of the vehicle .
Selon un deuxième aspect, l’invention propose un procédé de charge de la batterie d’alimentation électrique du moteur d’un véhicule automobile au moyen d’une telle batterie de secours, ladite batterie du véhicule étant gérée par un système de type BMS contrôlant au moins le niveau de charge de ladite batterie, ledit procédé prévoyant :According to a second aspect, the invention proposes a method for charging the electric power supply battery of the engine of a motor vehicle by means of such a backup battery, said battery of the vehicle being managed by a BMS type system controlling at least the charge level of said battery, said method providing:
- de connecter à ladite batterie le pack de piles de la batterie de secours ;connecting to said battery the battery pack of the backup battery;
- de mettre en communication le module avec le système de type BMS ;to put the module in communication with the BMS type system;
- d’interroger ledit système de type BMS pour, en fonction d’un critère d’acceptabilité de la charge unitaire au regard du niveau de charge donné par ledit système, activer ou non une pile électrique ;to interrogate said BMS type system to, depending on a criterion of acceptability of the unit load with regard to the level of charge given by said system, activate or not an electric battery;
- de décharger la charge unitaire d’une pile activée dans la batterie du véhicule.discharging the unit charge of an activated cell into the vehicle battery.
D’autres particularités et avantages de l’invention apparaîtront dans la description qui suit, faite en référence aux figures jointes, dans lesquelles :Other particularities and advantages of the invention will appear in the following description, made with reference to the attached figures, in which:
En relation avec ces figures, on décrit une batterie de secours 1 pour la mise en œuvre d’un procédé de charge de la batterie d’alimentation électrique du moteur d’un véhicule automobile.In connection with these figures, a backup battery 1 is described for the implementation of a method for charging the electrical supply battery of the engine of a motor vehicle.
La batterie de secours 1 comprend un boîtier 2 dans lequel est conditionné un pack comprenant au moins une pile électrique 3 qui est inerte avant activation et qui, après activation, délivre une charge électrique unitaire donnée. En particulier, les piles 3 utilisées sont primaires, c'est-à-dire non rechargeables, et délivrent leur charge unitaire de façon totalement autonome après activation.The emergency battery 1 comprises a casing 2 in which is packaged a pack comprising at least one electric battery 3 which is inert before activation and which, after activation, delivers a given unit electric charge. In particular, the batteries 3 used are primary, that is to say non-rechargeable, and deliver their unit charge completely independently after activation.
Selon une réalisation avantageuse, le pack comprend au moins une pile thermique 3 formée de cellules élémentaires comprenant chacune une pastille de chauffe, une cathode, un électrolyte à l’état solide en l’absence de chauffe et une anode. La principale qualité de ce type de pile 3 est le maintien de sa charge unitaire, sans maintenance, pendant plusieurs années.According to an advantageous embodiment, the pack comprises at least one thermal cell 3 formed of elementary cells each comprising a heating pad, a cathode, an electrolyte in the solid state in the absence of heating and an anode. The main quality of this type of battery 3 is the maintenance of its unit charge, without maintenance, for several years.
En particulier, l’ensemble des cellules reste inerte pendant la période de stockage et, après activation thermique, la charge unitaire est délivrée de façon autonome. En outre, le voltage de la pile 3 peut facilement être modulé en fonction du nombre de cellules empilées, et sa puissance en fonction de la dimension desdites cellules.In particular, all the cells remain inert during the storage period and, after thermal activation, the unit charge is delivered autonomously. Furthermore, the voltage of the battery 3 can easily be modulated according to the number of stacked cells, and its power according to the size of said cells.
Les cellules peuvent être réalisées par compression de poudre, une piste électrique reliant les pastilles de chauffe à deux bornes d’activation situées à l’extérieur de la pile 3. Le boîtier 2 intègre des moyens d’activation qui permettent l’envoi d’un courant de chauffe aux bornes d’activation de la pile 3, ledit courant induisant une élévation de température des pastilles chauffantes des différentes cellules jusqu’à une température de fonte de l’électrolyte.The cells can be produced by powder compression, an electrical track connecting the heating pads to two activation terminals located outside the battery 3. The box 2 incorporates activation means which allow the sending of a heating current at the activation terminals of cell 3, said current inducing a rise in temperature of the heating pads of the various cells to a melting temperature of the electrolyte.
La pile 3 ainsi amorcée délivre alors sa charge unitaire entre l’anode et la cathode jusqu’à sa décharge complète sans nécessiter d’intervention extérieure, notamment en ce que celle-ci chauffe durant sa décharge.The battery 3 thus primed then delivers its unit charge between the anode and the cathode until it is completely discharged without requiring external intervention, in particular in that it heats up during its discharge.
Le boîtier 2 de la batterie de secours 1 intègre également un dispositif de connexion 5 du pack de piles 3 à un système de type BMS de la batterie d’alimentation électrique du moteur d’un véhicule automobile, ledit système contrôlant le fonctionnement de la batterie du véhicule et notamment au moins le niveau de charge de ladite batterie.The box 2 of the emergency battery 1 also incorporates a device 5 for connecting the battery pack 3 to a BMS-type system of the electric power supply battery of the engine of a motor vehicle, said system controlling the operation of the battery of the vehicle and in particular at least the charge level of said battery.
En relation avec la
En particulier, le connecteur 6 est relié à un module 9 de communication et d’activation de chacune des piles 3, ledit module comprenant notamment les moyens d’activation desdites piles, chacune desdites piles étant reliée audit module par un câble de puissance 10. Selon une autre réalisation, le module 9 peut être intégré au système de type BMS du véhicule.In particular, the connector 6 is connected to a module 9 for communication and activation of each of the batteries 3, said module comprising in particular the means for activating said batteries, each of said batteries being connected to said module by a power cable 10. According to another embodiment, the module 9 can be integrated into the BMS type system of the vehicle.
Le procédé de charge prévoit, après connexion du pack de piles 3 de la batterie de secours 1 à la batterie du véhicule, de mettre en communication le module 9 avec le système de type BMS et d’interroger ledit système de type BMS pour, en fonction d’un critère d’acceptabilité de la charge unitaire au regard du niveau de charge donné par ledit système, activer ou non au moins une pile électrique 3.The charging method provides, after connection of the battery pack 3 of the emergency battery 1 to the battery of the vehicle, to put the module 9 in communication with the BMS type system and to interrogate said BMS type system to, in depending on a criterion of acceptability of the unit charge with regard to the level of charge given by said system, activating or not at least one electric battery 3.
En particulier, les moyens d’activation permettent l’envoi d’un courant de chauffe d’une pile thermique 3 en fonction d’un critère d’acceptabilité de la charge unitaire de ladite pile au regard du niveau de charge donné par le système de type BMS.In particular, the activation means allow the sending of a heating current from a thermal battery 3 according to a criterion of acceptability of the unit charge of said battery with regard to the level of charge given by the system. BMS type.
Ainsi, la décharge de la charge unitaire d’une pile 3 activée dans la batterie du véhicule n’est réalisée que dans la mesure où ladite charge est considérée comme acceptable pour ladite batterie en fonction des informations fournies par le système de type BMS.Thus, the discharge of the unit charge of a cell 3 activated in the battery of the vehicle is only carried out insofar as said charge is considered acceptable for said battery according to the information provided by the BMS type system.
En particulier, un tel procédé permet de réaliser la charge de la batterie du véhicule en toute sécurité, notamment dans la mesure où ladite charge peut être réalisée par un utilisateur du véhicule qui, outre le stress lié à l’éventuelle situation de panne, n’est pas familier avec ce type d’intervention.In particular, such a method makes it possible to carry out the charging of the battery of the vehicle in complete safety, in particular insofar as said charging can be carried out by a user of the vehicle who, in addition to the stress linked to the possible breakdown situation, n am not familiar with this type of intervention.
En outre, la décharge après activation étant autonome, il convient de fiabiliser les vérifications préalables, surtout dans le cas de piles thermiques 3 dont la température de fonctionnement peut augmenter de façon dangereuse en cas d’anomalie dans l’acceptation de la charge par la batterie du véhicule.In addition, the discharge after activation being autonomous, it is advisable to make the preliminary checks more reliable, especially in the case of thermal batteries 3 whose operating temperature can increase dangerously in the event of an anomaly in the acceptance of the charge by the vehicle battery.
En particulier, le critère d’acceptabilité comprend un niveau de charge maximale de la batterie du véhicule avant la charge, la pile 3 étant activée si la somme de sa charge unitaire et de la charge donnée par le système de type BMS est inférieure à au plus 80% de la charge maximale de la batterie. Selon une réalisation, le niveau de charge maximale de la batterie du véhicule peut être de 5 kWh pour pouvoir accepter la charge de la batterie de secours 1.In particular, the acceptability criterion comprises a maximum charge level of the vehicle battery before charging, the battery 3 being activated if the sum of its unit charge and of the charge given by the BMS type system is less than at more than 80% of the maximum battery charge. According to one embodiment, the maximum charge level of the battery of the vehicle can be 5 kWh in order to be able to accept the charge of the emergency battery 1.
