摘要： The application provides a battery, a manufacturing method and manufacturing system thereof and an electric device. The battery includes a case, a plurality of battery cells, and a fixation plate. In a first direction, the battery cells are sequentially arranged with side surfaces facing towards each other, and in a second direction, the battery cells are sequentially arranged with end surfaces facing towards each other. The fixation plate is disposed on at least one of the end surfaces of the plurality of battery cells for fixing the battery cells. In a third direction, the fixation plate connects the first portion of the case and connects the second portion. Each two of the first direction, the second direction and the third direction are perpendicular to each other. In the battery provided by the application, at least one end surface of the battery cell is provided with a fixation plate, so as to enable connection and fixing of the battery cells and the case, and the connection positions of the fixation plate and the case are also spaced apart with a small spacing distance. The connection strength of the fixation plate and the case can be effectively increased by virtue of the rigidity of the case, and an effective limiting function can be formed on the battery cells, thereby reducing the risk of the battery shaking during use and increasing the service life of the battery.

摘要： The disclosure provides a battery, a power consuming apparatus, and a method for manufacturing a battery. The battery includes a case, at least one row of battery cells, and a support member, where an accommodation space is formed inside the case; the at least one row of battery cells is arranged in the accommodation space, and each row of battery cells includes at least two battery cells arranged opposite each other in a first direction; and the support member extends in the first direction, and two ends of the support member are fixed to the case. The support member is arranged in the case, and an extending direction of the support member is the same as that of one row of battery cells, such that interference between the support member and the battery cell can be avoided. The two ends of the support member are fixed to the case, and structural stiffness and structural strength of the case can be improved by means of a supporting effect of the support member without reducing an energy density of the battery, thereby improving an anti-collision capability of the case, and reducing a risk of displacement or damage of the battery cell due to collision of the battery.

摘要： Embodiments of the present application provide a battery box (20), a battery, a holder (30), and an electrical apparatus, which can enhance installation stability of the battery. The battery box (20) includes a box body (200) for accommodating a battery cell (100); a first position-limit member (210) disposed on a side of a first wall (201) of the box body (200) away from the battery cell (100), wherein the first wall (201) is perpendicular to a first direction (x), the first direction (x) is parallel to a traveling direction of the electrical apparatus after the box (20) is mounted on the electrical apparatus, and the first position-limit member (210) is used to limit a relative displacement of the box (20) in the first direction (x). With this technical solution, after the box (20) is mounted on the electrical apparatus, the first position-limit member (210) can generate an acting force in the first direction (x) with the electrical apparatus to limit relative displacements of the box (20) in the traveling direction of the electrical apparatus and the direction opposite to the traveling direction, thereby improving the installation stability of the box (20).
