ENERGY STORAGE ASSEMBLY FOR A VEHICLE

An energy storage assembly includes a housing, an energy storage module and an attachment assembly. The energy storage module includes at least one energy storage system comprising one or more battery cells, the housing accommodating the energy storage module. The housing includes a housing panel at least partially delimiting the housing, the energy storage module comprising an energy storage module frame that in turn comprises a module panel. The attachment assembly includes an outer member, an inner member and a fastener, the outer member being rigidly attached to the housing panel. The outer member includes an outer member opening at least partially aligned with the housing panel opening, the inner member being located at least partially within the outer member opening such that a rotation of the inner member relative to the outer member around an axis of rotation will displace the inner member relative to the outer member in a direction parallel to the axis of rotation.
