A battery receptacle for a rail vehicle and a rail vehicle with a battery receptacle. The battery receptacle has a volume form which deviates from a cuboidal form. The battery receptacle has connection elements that are designed such that the battery receptacle can be pivotally connected to an associated battery box of the rail vehicle so that when the battery receptacle is rotated about an axis it can be rotated into the battery box or rotated out of the battery box.

A battery module includes a cell stack including a plurality of battery cells that are electrically connected to one another; a module housing accommodating the cell stack therein and including a pair of module holes formed in one surface; and a pair of venting hole terminals each including terminal hole communicating with the module hole, and electrically connected to the cell stack.

The application relates to a battery pack case and a battery pack. The battery pack case includes: a bottom plate and a side plate connected with the bottom plate, the bottom plate and the side plate surround to form an accommodating portion configured to accommodate a unit cell; the bottom plate is provided with a plurality of first grooves and a plurality of second grooves opening toward the accommodating portion, the plurality of first grooves are spaced apart from each other, the plurality of second grooves are spaced apart from each other, and the first grooves and the second grooves are arranged to cross each other. The bottom plate of the battery pack itself has good rigidity, is not prone to warp deformation, and can prevent the overflow of structural glue from contaminating the wiring harness or electrical components.

A grip structure connected to a main body of an imaging apparatus includes a battery storage part configured to store a battery; an inner side wall surface of the battery storage part includes a first corner, a second corner, and a third corner each having a curved shape when viewed in an insertion direction of the battery; and each of the first, second, and third corners has a radius of curvature equal to or greater than a radius of curvature of a cylindrical cell built into the battery.

The present disclosure provides a battery module, including a first battery cell arrangement structure, a second battery cell arrangement structure and a bus bar array. With battery cells stacked in a horizontal direction, a first battery cell arrangement structure and a second battery cell arrangement structure are stacked in a vertical direction, and a first bus bar of a bus bar array is used to sequentially connect the battery cells of the first battery cell arrangement structure and the second battery cell arrangement structure. As a result, a total positive electrode and a total negative electrode of a battery module are located at two ends of the battery module, which greatly reduces the possibility of a short circuit of the battery module and improves the safety of the battery module.

A busbar holder with two busbar trays maintains positive and negative busbars separate and insulated from each other to reduce the chance of accidental short circuits. Cells are located in a frame onto which the busbar holder is mounted. One busbar is located in a bottom tray of the busbar holder. Legs of the busbar project down through holes in the bottom tray, for connection to one set of terminals of the cells. A top tray is placed over the bottom tray. Another busbar, in the top tray, is connected through holes in both trays to the other set of terminals of the cells. The busbar in the bottom tray is covered by the top tray. Holes through the busbar holder allow for hot gases to escape in the event of cell failure.

The battery case according to one embodiment may comprise: a base plate member; a support member which surrounds the base plate member, has a closed cross-section, and supports the base plate member; and an absorption member which is coupled to the outside of the support member so as to form a closed cross-section and absorbs external impacts.

A tray (20) including a bottom wall (21) and a peripheral side wall (22) erected from an outer periphery of the bottom wall (21) includes a high-strength portion HT having a high tensile strength; and a low-strength portion LT having a tensile strength lower than that of the high-strength portion HT. The low-strength portion LT includes a recessed portion (C) having a corner portion (22C) in a first side wall inner surface (221a) and a second side wall inner surface (222a) which are adjacent to each other at a minor angle and a corner section (21C) on an upper surface (21a) of the bottom wall (21) having a minor angle to each of the first side wall inner surface (221a) and the second side wall inner surface (222a).
