Certains véhicules automobiles, comme les véhicules électriques ou hybrides, comprennent une batterie d'alimentation d'un moteur électrique d'entraînement. Du fait des autonomies de ces véhicules, il peut se révéler intéressant d'échanger cette première batterie, contre une nouvelle batterie remplie d'énergie, lorsque le niveau d'énergie de la première est faible. Ceci peut être fait dans une station de remplacement de batteries similaire à une station service dans laquelle on peut remplir un réservoir de carburant d'un véhicule automobile. Some motor vehicles, such as electric or hybrid vehicles, include a battery pack for an electric drive motor. Because of the autonomy of these vehicles, it may be interesting to exchange this first battery, against a new battery full of energy, when the energy level of the first is low. This can be done in a battery replacement station similar to a service station in which a fuel tank of a motor vehicle can be filled.
Dans ces stations, les batteries sont retirées des véhicules, chargées « hors des véhicules» puis remontées sur de nouveaux véhicules. On connaît de telles stations notamment des documents DE4229687 et EP0476405. In these stations, the batteries are removed from the vehicles, loaded "out of vehicles" and reassembled on new vehicles.

Le mode de fonctionnement de secours présente par exemple par rapport au mode de fonctionnement nominal des règles de priorité différentes liant les différentes fonctions de la station et donc les différents systèmes, dispositifs et moyens de la station. Moreover, in the event of failure of the commercial electricity network, the replacement station switches from a nominal operating mode to a backup operating mode. The emergency operating mode has, for example, in relation to the nominal operating mode, different priority rules linking the various functions of the station and therefore the various systems, devices and means of the station.
Par exemple, le mode de fonctionnement de secours peut être caractérisé par une désactivation d'un ou plusieurs systèmes de la station, notamment une désactivation du système de lavage et/ou une désactivation du système de conditionnement d'air et/ou une désactivation du système de charge de batteries et/ou une désactivation d'un système de refroidissement de batteries. De préférence, les dispositifs de manipulation et/ou de manutention des batteries et le dispositif de montage et de démontage des batteries resteront actifs pour permettre, malgré la défaillance du réseau électrique commercial, aux automobilistes de procéder à des opérations d'échanges de batteries. Ainsi, les opérations de recharge des batteries pourraient être différées jusqu'à ce que le réseau électrique commercial soit de nouveau opérationnel. For example, the emergency mode of operation may be characterized by a deactivation of one or more systems of the station, in particular a deactivation of the washing system and / or a deactivation of the air conditioning system and / or a deactivation of the air conditioning system. battery charging system and / or deactivation of a battery cooling system. Preferably, the devices for handling and / or handling of the batteries and the device for mounting and dismounting the batteries will remain active to allow, despite the failure of the commercial electricity network, motorists to carry out battery exchange operations. Thus, battery recharging operations could be deferred until the commercial electricity network is operational again.
De préférence, dans un mode de fonctionnement nominal de la station c'est- à-dire lorsque le réseau électrique commercial est opérationnel, on utilise l'énergie issue de l'au moins une source d'énergie alternative pour limiter la consommation sur le réseau électrique commercial. Preferably, in a nominal operating mode of the station that is to say when the commercial electricity network is operational, the energy from the at least one alternative energy source is used to limit the consumption on the commercial electricity network.
De préférence, l'utilisation de l'énergie issue de l'au moins une source d'énergie alternative est fonction de : le mode de fonctionnement de la station (nominal ou de secours) et/ou Preferably, the use of energy from the at least one alternative energy source is a function of: the operating mode of the station (nominal or emergency) and / or
la puissance instantanée nécessaire au fonctionnement de la station et/ou  the instantaneous power required to operate the station and / or
une prévision de la puissance instantanée qui sera nécessaire au cours d'une période prédéterminée à venir et/ou  a prediction of the instantaneous power that will be needed over a predetermined future period and / or
la puissance instantanée disponible en sortie de l'au moins une source d'énergie alternative et/ou  the instantaneous power available at the output of the at least one alternative energy source and / or
une prévision de la puissance instantanée qui sera disponible en sortie de l'au moins une source d'énergie alternative au cours d'une période prédéterminée à venir et/ou  a prediction of the instantaneous power that will be available at the output of the at least one alternative energy source during a predetermined future period and / or
la quantité d'énergie stockée au niveau de la station.  the amount of energy stored at the station.
Grâce à la station selon l'invention, le cas d'une défaillance du réseau électrique commercial alors que la batterie usagée d'un véhicule a été déposée et que la nouvelle batterie n'est pas encore remontée sur le véhicule n'est pas problématique. En effet, le basculement de la station dans un mode de secours lui permet d'utiliser de l'énergie produite par l'au moins une source d'énergie alternative et stockée dans un moyen de stockage et ainsi d'activer les différents systèmes qui permettent le montage de la nouvelle batterie sur le véhicule automobile. Thanks to the station according to the invention, the case of a failure of the commercial electricity network while the used battery of a vehicle has been deposited and that the new battery is not yet reassembled on the vehicle is not problematic . Indeed, the switching of the station into a backup mode allows it to use energy produced by the at least one alternative energy source and stored in a storage means and thus activate the various systems that allow the installation of the new battery on the motor vehicle.
De même, grâce a la station selon l'invention, l'utilisation de l'énergie peut être optimisée. En particulier, dans le cas où les ressources énergétiques sont abondantes et/ou où suffisamment d'énergie est stockée dans le moyen de stockage, l'énergie produite par l'au moins une source d'énergie alternative peut être utilisée pour limiter la consommation sur le réseau électrique commercial et/ou pour limiter le coût de cette consommation. On remarque que compte tenu de la superficie de la station de remplacement, il est aisé d'agencer, au niveau de celle-ci, un ensemble de panneaux photovoltaïques. Similarly, thanks to the station according to the invention, the use of energy can be optimized. In particular, in the case where the energy resources are abundant and / or where enough energy is stored in the storage means, the energy produced by the at least one alternative energy source can be used to limit the consumption. on the commercial electricity grid and / or to limit the cost of this consumption. Note that given the size of the replacement station, it is easy to arrange, at this level, a set of photovoltaic panels.
