Abstract: The invention relates to a system for locking and/or unlocking a power battery under a vehicle chassis, comprising a plurality of tools, each of which includes elements for aligning said tool relative to the battery along a longitudinal axis and along a transverse axis, elements for bearing against the underside of the chassis and enabling balancing, and locking and/or unlocking elements for actuating an attachment bolt between a locked configuration, in which the battery is locked under the chassis, and an unlocked configuration, in which the object is released.

Abstract: A system is provided for locking and/or unlocking an object, such as a power battery of a drive engine of an electric or hybrid motor vehicle, under a structure such as a chassis of the vehicle, including a plurality of locks ensuring the attachment of the object under the structure. The locks are secured to the object and/or structure and each include a hook configured for drawing the object to the structure by compressing an elastically deformable member inserted between the object and the structure and for supporting the object relative to the structure at the end of the approximation travel, as well as a transmission device driving the hook during the drawing travel and configured such as to be actuated by an actuation tool that is separate from the structure and the object.

Abstract: An arrangement for a motor vehicle including a mechanism for holding an energy storage device, and associated vehicle. The arrangement includes a chassis, an electrical energy storage device, a fixing device for fixing the energy storage device to the chassis of the vehicle, a holding mechanism configured to switch, in case of a breakage of at least a portion of the fixing device, from a passive configuration in which it does not support the energy storage device to an active configuration in which it supports the energy storage device in such a way to hold the energy storage device close to the chassis.

Abstract: The invention relates to a device for degassing the battery (1) of an automobile, that comprises a degassing pipe (4) having a first end which is provided in the upper portion of the battery outside the latter and is connected to the inside of the battery, while the second end is provided in the vicinity of the lower portion of the battery outside the latter and is connected to an opening giving into a discharge space. According to the invention, said second end is connected to said discharge space through a check valve that only allows the flow from said first end to the discharge space.
