Abstract: A device for installing and uninstalling a battery on an underside of an electric or hybrid vehicle, the underside of the vehicle lying within a first substantially horizontal plane. The device includes a lift table that vertically moves an engaging member capable of engaging with the underside of the vehicle. The engaging member is moved by the table to mechanically engage with the underside of the vehicle, the underside of the member then being arranged in a second substantially horizontal plane in a state in which, due to a relative inclination between the first and second plane, the engaging member cannot engage with the underside of the vehicle. The lift table is raised using at least two cables, the elasticity of which makes it possible to compensate for the relative inclination of the two planes to enable the engaging member to engage with the underside of the vehicle.

Abstract: The invention relates to the installation and/or removal of a power supply battery (11) of an electric motor for driving an electric or hybrid motor vehicle in/from a storage cell (12) of a battery storage structure (10), which includes a step of actuating a locking mechanism (13) with which the storage cell is provided in order to move same between a locked state, in which the locking mechanism immobilizes, in space, the battery with which the latter engages inside the storage cell in a storage position, and an unlocked state, in which the locking mechanism frees, in space, the battery from the storage position thereof.

Abstract: A positioning of a motor vehicle in absence of action of a motor or engine that drives the motor vehicle includes centering the vehicle transversely with respect to a longitudinal-vertical reference plane that is invariable in a fixed frame of reference until a center of a first axle of the vehicle coincides or more or less coincides with the reference plane whatever the gauge width of the first axle of the vehicle.
