Abstract: A battery box upper cover including a top wall, a side wall, and an edge portion is described. A first end of the side wall is connected to the top wall, an opening of the battery box upper cover is formed at a second end of the side wall, and the second end is connected to the edge portion. The edge portion extends along a first direction at the second end, the first direction being parallel to a plane on which the opening is located and away from the opening, a second surface of the edge portion is inclined toward the plane on which the opening is located along the first direction, and a first surface of the edge portion is away from the top wall relative to the second surface. Embodiments can solve the problem of insufficient safety performance of the battery.

Abstract: A cable for a battery includes a conductive member that extends in a longitudinal direction of the cable, an expansion member spaced with the conductive member, and an insulation member covering the periphery of the conductive member and the expansion member. The insulation member has a through hole. The expansion member is configured to expand and overflow to the outer surface of the insulation member through the through hole when the temperature reaches a threshold.

Abstract: This application relates to an oriented pressure relief structure, a battery box, a battery, and an electric apparatus. A pressure relief assembly can control, based on a relationship between an internal pressure of the battery and a preset pressure, a cover to switch between a pressure relief position and a sealing position to implement opening and closing of a pressure relief channel, thereby implementing reuse of the oriented pressure relief structure.

Abstract: A fastening structure, a battery box, and a battery are described The fastening structure is configured to fasten a first object and a second object, and the fastening structure includes: a first fastener fixed on the first object, where the first fastener has a first fastening portion; a second fastener detachably connected to the first fastener, where the second fastener has a second fastening portion and a fitting portion; and a locking member fixed on the first object or the second object, where when the second fastener is connected to the first fastener, the second fastening portion is fitted with the first fastening portion, and the second fastener operably rotates relative to the first fastener to drive the first object to move toward the second object; and the second fastener is configured to lock the fitting portion into the locking member in a rotation process.

Abstract: A pressure relief mechanism includes: a pedestal, a cover assembly, and a position limiter. An exhaust port is provided on the pedestal. The cover assembly is configured to close or open the exhaust port. The position limiter is snap-fastened to the cover assembly. The position limiter includes a first elastomer and a first limiting portion. The first limiting portion is configured to: when the cover assembly closes the exhaust port, restrict the position limiter from moving relative to the pedestal; and when a pressure in the box increases, make the position limiter move along an opening direction of the cover assembly to free the first limiting portion from constraint of the pedestal and enable the position limiter to rotate relative to the cover assembly under resilience of the first elastomer.

Abstract: A top cover includes a first cover plate, a first side plate, and a second side plate. The first side plate and the second side plate are opposite to each other and connected to one side of the first cover plate. A first through-hole and a second through-hole opposite to each other are created on the first side plate and the second side plate respectively. The first connecting seat is connected to a surface of the first side plate, the surface being oriented toward the second side plate.

Abstract: The present application discloses a case of a battery, a battery and an electrical device. The case may include: a heat manager configured for accommodating a fluid to adjust a temperature of battery cells; a protector configured for protecting the heat manager; and a heat absorber arranged between the heat manager and the protector, and configured for absorbing heat generated by the heat manager when a temperature of the heat manager reaches a threshold value.

Abstract: The present disclosure provides an installation device, a battery, an electric device, a manufacturing method and a manufacturing equipment for the battery.
