Description

SYSTEME DE REFROIDISSEMENT DE BATTERIE DE VEHICULE AUTOMOBILE, PROCEDE ET PROGRAMME SUR LA BASE D’UN TEL SYSTEMEMOTOR VEHICLE BATTERY COOLING SYSTEM, METHOD AND PROGRAM BASED ON SUCH A SYSTEM

L'invention se rapporte au domaine des véhicules rechargeables, de covoiturage ou de flotte, taxi, etc.The invention relates to the field of rechargeable vehicles, carpooling or fleet vehicles, taxis, etc.

Les véhicules rechargeables ont en général deux options pour refroidir la batterie de traction :
- un refroidissement passif par convection d’air ambiant ; ou
- un refroidissement actif à air ou eau, avec un circuit dédié refroidi par un compresseur.Plug-in vehicles generally have two options for cooling the traction battery:
- passive cooling by ambient air convection; or
- active air or water cooling, with a dedicated circuit cooled by a compressor.

Dans le premier cas, le refroidissement est insuffisant pour de fortes puissances prolongées, ce qui limite la puissance de charge embarquée (ou « plug-in » en langue anglaise) et donc prolonge le temps de charge.In the first case, the cooling is insufficient for prolonged high powers, which limits the on-board charging power (or “plug-in” in English) and therefore prolongs the charging time.

Dans le deuxième cas, il y a un composant supplémentaire par véhicule avec un système qui rajoute un coût de performance, du volume à répartir, puise dans l’énergie de la batterie et ponctionne de la puissance de charge embarquée pour refroidir le pack batterie.In the second case, there is an additional component per vehicle with a system that adds a performance cost, volume to be distributed, draws on battery energy and draws on-board charging power to cool the battery pack.

Un objectif de la présente invention est de remédier aux défauts de l’art antérieur, et notamment de proposer une solution de refroidissement pour de fortes puissances, sans utiliser des quantités significatives d’énergie électrique du véhicule, et l’autonomie de la batterie du véhicule automobile.An objective of the present invention is to remedy the defects of the prior art, and in particular to propose a cooling solution for high powers, without using significant quantities of electrical energy from the vehicle, and the autonomy of the battery of the motor vehicle.

Pour atteindre cet objectif, l’invention propose un système de refroidissement destiné à au moins un véhicule automobile présentant un repère dans l’espace comprenant un axe longitudinal suivant une direction de déplacement du véhicule automobile, un axe latéral perpendiculaire à l’axe longitudinal, et un axe vertical perpendiculaire à l’axe longitudinal et à l’axe latéral,
le véhicule automobile comprenant une batterie de traction rechargeable disposée dans un carter en soubassement du véhicule automobile,
caractérisé en ce que le système de refroidissement comprend au moins une plaque de refroidissement configurée pour être disposée contre le carter sous le véhicule automobile, de sorte que la plaque de refroidissement refroidisse la batterie de traction.To achieve this objective, the invention proposes a cooling system intended for at least one motor vehicle having a spatial reference point comprising a longitudinal axis along a direction of movement of the motor vehicle, a lateral axis perpendicular to the longitudinal axis, and a vertical axis perpendicular to the longitudinal axis and to the lateral axis,
the motor vehicle comprising a rechargeable traction battery arranged in a housing under the motor vehicle,
characterized in that the cooling system comprises at least one cooling plate configured to be arranged against the housing under the motor vehicle, such that the cooling plate cools the traction battery.

Avantageusement, l’invention propose un système externe au véhicule, qui applique lors de la charge une plaque de refroidissement actif sous le véhicule contre le boitier batterie.Advantageously, the invention proposes a system external to the vehicle, which applies an active cooling plate under the vehicle against the battery box during charging.

Selon une variante, le système de refroidissement comprend en outre un moyen d’application pour relever la plaque de refroidissement et l’appliquer contre la batterie de traction.According to a variant, the cooling system further comprises an application means for raising the cooling plate and applying it against the traction battery.

Cela permet de mettre la plaque en contact avec la batterie pour la refroidir.This allows the plate to come into contact with the battery to cool it.

Selon une variante, le système de refroidissement comprend en outre un moyen de déplacement pour déplacer la plaque de refroidissement et la disposer sous le véhicule automobile.According to one variant, the cooling system further comprises a moving means for moving the cooling plate and arranging it under the motor vehicle.

Cela permet de déplacer la plaque pour la mettre à sous le véhicule, par exemple au moyen de roues.This allows the plate to be moved to place it under the vehicle, for example by means of wheels.

Selon une variante, le système de refroidissement comprend en outre une station de refroidissement connectée à la plaque de refroidissement.According to one variant, the cooling system further comprises a cooling station connected to the cooling plate.

Cela permet d’avoir une structure spécifique pour refroidir la plaque de refroidissement.This allows for a specific structure to cool the cooling plate.

Selon une variante, le système de refroidissement comprend en outre une station de charge comportant un connecteur de charge pour la batterie du véhicule automobile, la station de charge étant disposé au-dessus ou en dessous de la station de refroidissement en référence à l’axe vertical.According to one variant, the cooling system further comprises a charging station comprising a charging connector for the battery of the motor vehicle, the charging station being arranged above or below the cooling station with reference to the vertical axis.

Cela permet de coupler une station de charge à une station de refroidissement au même endroit, de sorte à augmenter la vitesse de charge de la batterie du véhicule.This allows a charging station to be coupled with a cooling station in the same location, thereby increasing the charging speed of the vehicle battery.

Un autre objet de l'invention concerne un procédé de refroidissement au moyen d’un système de refroidissement selon l'invention, caractérisé en ce qu’il comprend au moins une étape de refroidissement au moyen de la plaque de refroidissement pendant la charge de la batterie du véhicule automobile.Another subject of the invention relates to a cooling method using a cooling system according to the invention, characterized in that it comprises at least one cooling step using the cooling plate during charging of the battery of the motor vehicle.

L'invention a en outre trait à un programme d’ordinateur comprenant des instructions de code de programme pour l’exécution des étapes du procédé de refroidissement selon l'invention, lorsque ledit programme fonctionne sur un ordinateur.The invention further relates to a computer program comprising program code instructions for executing the steps of the cooling method according to the invention, when said program runs on a computer.

L'invention sera davantage détaillée par la description de modes de réalisation non limitatifs, et sur la base des figures annexées illustrant des variantes de l'invention, dans lesquelles :
- illustre schématiquement un système de refroidissement selon un mode de réalisation préféré de l’invention, isolé ; et
- illustre schématiquement le système de refroidissement de la contre un véhicule automobile.The invention will be further detailed by the description of non-limiting embodiments, and on the basis of the appended figures illustrating variants of the invention, in which:
- schematically illustrates a cooling system according to a preferred embodiment of the invention, isolated; and
- schematically illustrates the cooling system of the against a motor vehicle.

L'invention concerne un système de refroidissement externe au véhicule V. Le système de refroidissement applique lors de la charge une plaque de refroidissement P actif sous le véhicule V contre le boitier (carter) de la batterie.The invention relates to a cooling system external to the vehicle V. The cooling system applies an active cooling plate P under the vehicle V against the battery housing (casing) during charging.

Dans les stations SR, SC équipées, la plaque de refroidissement P externe s’applique contre les boitiers de batterie par-dessous le véhicule V de flotte concernée. Pendant la charge à la station SR, SC, on procède à un refroidissement actif (à air ou eau, mais de préférence à eau pour une meilleure efficacité), pendant le temps de la charge.In equipped SR, SC stations, the external cooling plate P is applied against the battery boxes from below the vehicle V of the fleet concerned. During charging at the SR, SC station, active cooling is carried out (air or water, but preferably water for better efficiency), during the charging time.

L’invention permet d’avoir une amélioration du potentiel de puissance de charge, et un temps de charge réduit d’un facteur d’environ 3 comparé à un véhicule non équipé de système de refroidissement actif.The invention allows for an improvement in the charging power potential, and a charging time reduced by a factor of approximately 3 compared to a vehicle not equipped with an active cooling system.

Le système de refroidissement s'indexe à l'aide de marques du soubassement du véhicule V pour s'aligner avec le boitier batterie du véhicule V.The cooling system is indexed using marks on the vehicle underbody V to align with the vehicle battery box V.

Le système plaque ensuite la plaque de refroidissement P sur le boitier et lance le refroidissement. Un interfaçage avec le logiciel de la station permet de signaler le refroidissement au véhicule pour limiter la puissance de charge à une calibration adaptée.The system then places the cooling plate P on the housing and starts cooling. An interface with the station software allows the cooling to be signaled to the vehicle to limit the charging power to a suitable calibration.

Le véhicule peut procéder à sa charge en se connectant à la borne de recharge SC comme d'usage. Grâce au gain de temps passé en charge, le système permet d’améliorer les flottes privées et de rendre les véhicules de partage plus fréquemment accessibles.The vehicle can charge by connecting to the SC charging station as usual. Thanks to the time saved on charging, the system can improve private fleets and make shared vehicles more frequently accessible.
