Description

TITLE: Arrangement comprising a tank and a battery, the battery being fixed to the tank. Technical field of the invention The invention relates to an arrangement comprising a tank and a traction and/or propulsion battery for a vehicle, the battery being fixed to the tank. The invention also relates to a body comprising such an arrangement. The invention also relates to a vehicle comprising such an arrangement or such a body. State of the prior art A vehicle, in particular a motor vehicle, equipped with a powertrain using an energy fluid generally requires a tank for such a fluid. Thus, in the case of a powertrain using dihydrogen, for example comprising a fuel cell, such a tank generally comprises one or more metal bottles each having a substantially cylindrical shape whose length is much greater than the diameter. Such hydrogen bottles are particularly heavy and bulky. Moreover, for a bus or a coach, such bottles are generally arranged substantially in a horizontal plane on the roof. Typically, such a vehicle includes a battery for storing electrical energy, particularly electrical energy produced by such a fuel cell. However, bulky and heavy storage bottles are not suitable for a passenger car type motor vehicle, particularly for issues related to aesthetics and/or aerodynamic performance and/or road holding performance. However, it is advisable to have a bulky tank in order to be able to store a maximum of dihydrogen, a guarantee of autonomy. for such a vehicle. Furthermore, it is also appropriate to install such a particularly bulky electric energy storage battery on such a vehicle. Presentation of the invention The object of the invention is to provide an arrangement that overcomes the above drawbacks. In particular, the invention provides an arrangement comprising a battery attached to the tank so as to maximize the storage volume within the tank. Summary of the invention To achieve this objective, the invention relates to an arrangement for a vehicle, the arrangement comprising: - a tank intended to store an energy fluid, in particular dihydrogen, and - a traction and/or propulsion battery of such a vehicle, the battery being attached to the tank. The reservoir may include a battery receiving cavity, the battery being able to extend at least partially within the receiving cavity. The battery and the cavity can each extend mainly on either side of the same longitudinal and transverse plane. The tank may be obtained at least partially from composite material, in particular from composite material comprising fiberglass and/or carbon fiber. The arrangement may include attachment means for securing the battery to the tank. The fastening means may comprise threaded elements and tapped elements, the threaded elements being able to cooperate with the tapped elements, in particular so as to pass through the battery and/or the tank, in particular by sandwiching them. The tank may include vertical wells and the battery may include bores of vertical axes, the bores may be opposite vertical wells, the tapped elements and/or the threaded elements may be arranged in vertical wells and/or within bores opposite vertical wells. The arrangement may include conduits and/or electrical wiring and the reservoir may include longitudinal wells, the conduits and/or electrical wiring may extend within the longitudinal wells. The invention also relates to a vehicle body, in particular for a motor vehicle, the body comprising an arrangement as defined above, the body comprising at least one side member and/or at least one cross member, the tank being fixed to the at least one side member and/or to the at least one cross member. The invention also relates to a vehicle, in particular a motor vehicle, comprising a body as defined above, or an arrangement as defined above.
