<p>#CMT# #/CMT# The assembly has a protection element e.g. rigid metallic protection plate (8) or beam, arranged between a receptacle (2) of an electric energy storage system of a vehicle (3) and a part i.e. rear crosspiece (7), of a chassis (4) of the vehicle. Fluid compression damping units are formed of cylinders (9, 10) such as pneumatic cylinders, that are arranged between the protection element and corresponding structure elements e.g. side rails (5, 6), of the vehicle. The damping units are arranged in fluid communication with a hydropneumatic or oleo-pneumatic suspension system of the vehicle. #CMT#USE : #/CMT# Assembly for protecting a receptacle of a high capacity electric energy storage system i.e. lithium-ion battery, of a vehicle (claimed) e.g. electric vehicle or hybrid vehicle, against the penetration of a chassis part i.e. rear crosspiece, of the vehicle during central or lateral rear impact of the vehicle. Can also be used for protecting the receptacle of the high capacity electric energy storage system against penetration of a front crosspiece of the vehicle during the impact of the vehicle. #CMT#ADVANTAGE : #/CMT# The cylinders of the fluid compression damping units are arranged between the protection element and the corresponding structure elements, to assure optimized protection of the receptacle against the penetration of the rear crosspiece of the vehicle during rear impact of the vehicle, and to permit portion of efforts transmitted by the crosspiece to the protection element, thus limiting the risk of deformation and rupture of the protection element, and hence limiting the risk of impact on the receptacle and explosion of the storage system. The damping units are arranged in fluid communication with the hydropneumatic or oleo-pneumatic suspension system of the vehicle so as to apply high pressure required for damping the efforts transmitted during high intensity impacts of the vehicle. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial bottom perspective view of a vehicle provided with a protection assembly. 2 : Receptacle 3 : Vehicle 4 : Chassis 5, 6 : Side rails 7 : Rear crosspiece 8 : Rigid metallic protection plate 9, 10 : Cylinders.</p> |
