摘要： An energy storage device with a housing and with at least one storage module accommodated therein, and a frame to which the housing is fastened by screw elements screwed at distinct fastening positions. The frame has at least two longitudinal beams, which are formed by metal hollow profile elements. Each hollow profile element has a main portion and at least one chamber portion which projects laterally therefrom towards the housing, into which the screw elements are screwed in. The chamber portion is provided with one or more weakening devices to facilitate collapse of the chamber portion in the event of a force acting with a horizontal force component.

摘要： A rechargeable power system includes a bracket configured to mount at a panel of a workstation. The bracket includes an upper cover, a receiving plate and a lower cover. The upper cover is disposed at an upper surface of the panel and at least partially circumscribes an aperture formed through the panel. An aperture is formed through the upper cover and is at least partially aligned with the aperture of the panel. The receiving plate is disposed at a lower surface of the panel and extends at least partially along the aperture of the panel. The lower cover is disposed below and extends at least partially along the receiving plate. A battery pack is received through the apertures of the upper cover and the panel and at a receiving portion of the receiving plate. The battery pack is operable to electrically power an electronic device at the workstation.
