    [0001] Field of the Invention The present invention relates to a battery lift truck equipped with a battery system for its power supply and consisting of at least two battery parts formed from battery modules and each battery module. being maintenance free. STATE OF THE ART Electric battery lift trucks (battery powered electric lift truck) include a battery system that provides electrical power to power the vehicle drive and equipment. Equipment includes for example a hydraulic system for controlling the load receiving device of the lifting mast. The battery system generally consists of a single traction battery having a plurality of battery cells integrated into a single battery pack. These cells are, for example, lead-acid cells which, in order to provide the usual necessary voltage for forklift trucks or transporter trolleys, for example of 24, 48 or 80 V are in series. At the same time, the different battery cells and also the modules grouped into a battery of cells are connected in parallel with each other so that the traction battery can have the desired capacity. The mounting of this traction battery made in the form of a battery pack is usually done centrally on the vehicle, between the axles. In the case of a forklift truck and counterweight as an embodiment of the lift truck or carrier, the traction battery is housed under the seat of the driving position. In the case of storage facility devices, there are facilities in different positions between the axles following the realization of the carrier carriage; however, this always corresponds to a position in front of or behind the driving position. The disadvantage of this state of the art is that the traction battery is constituted by a large monolithic block which necessarily influences the design of the vehicle and determines it. In addition, in the case of lead-acid batteries it is disadvantageous that the orientation of the different battery cells is predefined because these cells must be installed in a standing position. In addition, accessibility must be guaranteed for cell maintenance. As according to the current development of batteries, there are known forklifts or carriers equipped with battery not requiring maintenance. It is particularly advantageous in this context to use chemical reaction battery variants, that is to say batteries other than lead-acid batteries and among others, for example, lithium-ion batteries. It is also known to install in a battery housing in one place, several separate batteries, of the same type which are thus easier to handle for transport. The disadvantage of this known solution is that this distribution between several batteries of the same type only allows a very limited flexibility for the installation of the batteries in the vehicle.
    [0002] OBJECT OF THE INVENTION The object of the present invention is to develop a battery transporter carriage comprising at least two battery modules making it possible to avoid the above disadvantages, and to have a greater flexibility of vehicle design while improving the overall capacity of the battery system. DESCRIPTION AND ADVANTAGES OF THE INVENTION For this purpose, the subject of the invention is a battery-powered forklift equipped with a battery system for its power supply, the battery system consisting of at least two battery parts. formed of battery modules and each battery module being maintenance-free, this lift truck being characterized in that the battery parts are installed in at least two of the following locations of the lift truck: between the front axle and the rear axle, directly above the lower floor of the vehicle, above the rear axle, in the area of the driver's headlamp, in particular on the top of the roof, on the rear side of the driver's headliner at the top, on the rear wall of the driver's headlamp, and on the front side of the driver's headlamp, including a driving cab.
    [0003] Advantageously, this avoids a monolithic battery pack of large size which allows greater flexibility or flexibility of installation in the vehicle. This allows to design more freely the vehicle. This solution is advantageously made possible, in particular by virtue of modern battery techniques which do not impose any direction of installation of the different battery modules or cells, unlike lead-acid battery cells which must be installed in a standing position. . Examples of such battery cells or battery modules are lithium-ion batteries. Such maintenance-free battery modules also have the property of fast charging. This allows at least to install some of the battery parts so that they can be changed quickly. Instead of changing a part of the discharged battery, you can also perform a quick recharge. It can be considered in particular to combine this procedure in that one or two battery parts are replaced and the others are left in place, which allows an exchange without difficulty when a battery is discharged. A battery part may consist of a single battery module; the expression "battery module" corresponds to a unit of battery cells. But there can also be any number of battery modules joined to form a battery part. Several battery modules can be connected in series or alternatively, several battery modules can be connected in parallel. This can also be combined in any way in that, for example, a first group of battery modules is connected in parallel and a second group of battery modules is also connected in parallel but the two groups are then connected in series. According to an advantageous development, the transporter truck is a forklift and counterbalance truck offering other locations for receiving at least one battery part, directly under the driver's seat, above and away from the floor of the vehicle. and / or above a counterweight and / or at least partly in the counterweight.
    [0004] In the case of a forklift and counterweight, it is possible to house the counterweight or the counterweight, particularly the advantageous parts of the battery system in the form of battery parts. This results in the advantageous effect that the weight of the battery part participates in the counterweight function. Advantageously, the battery parts have different geometrical dimensions, which gives a very great flexibility or flexibility since the battery parts can be adapted to the available dimensions and not the opposite, during the development of a carrier carriage while it was to design the housing according to the geometry of the batteries. The battery parts may have different voltages. The voltages can be transformed by the clean electronics of the conveyor or by separate electronics or several battery parts can be connected together to provide a battery system with uniform voltage and capacitance. For example, two battery parts can be connected in series to reach the voltage of a third battery part with which a connection is made in parallel.
    [0005] Advantageously, the battery parts comprise at least some of them, a voltage converter. Thus, the battery part itself supplies the voltage at the level necessary for the transporter carriage. The drum parts may have different capacities. In this case, by a suitable connection of the battery parts there will be a battery system providing a supply voltage adapted to the demand of the transporter carriage and a uniform capacity so that effectively and in number, we will always have as much batteries in parallel and in series.
    [0006] Advantageously, the battery parts comprise a monitoring electronics. In the case of current, maintenance-free batteries, such as lithium-ion batteries or comparable technologies, it is necessary to use a monitoring electronics to monitor the battery.
    [0007] According to a preferred development, the battery parts have a uniform communication interface which supplies the monitoring electronics with the data of the battery parts, for example the nominal voltage and / or the actual voltage and / or the nominal capacity. and / or the actual capacity. Such a communication interface corresponds for example to a communication bus such as the CAN bus. One or more battery parts may include a controller that processes the data. The transporter or lift truck may comprise a control device processing the data. This control device makes it possible to supply, from the monitoring electronics of the different battery parts, the data corresponding to the entire battery system, for example the target voltage and / or the actual voltage and / or the capacity. setpoint and / or actual capacity. One can also have a centralized and uniform battery system in which all the battery parts are controlled by the controller.
