NOVELTY - The device has a pin comprising a rod and a broad head (T). The broad head bears on bridges adjacent to rectangular openings under an effect of the weight of a traction battery such that the pin moves longitudinally and transversely to an electric or hybrid vehicle along two alignments of the openings in case of a front or rear impact between the vehicle and an obstacle and a side impact between the vehicle and another obstacle, respectively. Deformation and breaking of the bridges absorb kinetic energy of the battery, where the bridges separate the openings formed in the two alignments.    USE - Energy absorption device for mounting or fastening a traction battery i.e. lithium ion battery, to a body of an electric or hybrid vehicle (claimed) i.e. hybrid electric vehicle.    ADVANTAGE - The broad head bears on the bridges adjacent to the openings under the effect of the weight of the battery such that the pin moves longitudinally and transversely to the vehicle along the two alignments of the openings in case of the front or rear impact between the vehicle and the obstacle and the side impact between the vehicle and the other obstacle, respectively, where the deformation and breaking of the bridges absorb the kinetic energy of the battery, thus enabling prevention of falling of the battery in case of the side impact and multiple impacts of the vehicle, and hence simplifying wreckage evacuation operations done by dedicated services. The device exhibits a simple and compact structure and reduced weight, and is inexpensive. The pin and the plate are dismountable parts, thus facilitating repairability of the vehicle after the front, rear and side impacts. The device minimizes reinforcements to be added to a structure of the vehicle, thus enabling integration of the plate with a structure of the battery while reducing reinforcement of a body of the vehicle, and hence reducing weight of the vehicle.
