This application relates to the technical field of energy storage devices, and in particular, to an upper cover assembly and a battery pack. The upper cover assembly includes: an upper cover body, including a top plate and a side plate connected to an outer periphery of the top plate, wherein an exhaust vent is provided in the side plate; and an exhaust unit, including a first exhaust unit and a second exhaust unit that communicates with each other, wherein the first exhaust unit is disposed on the top plate, the second exhaust unit is disposed on the side plate, and the first exhaust unit communicates with the exhaust vent through the second exhaust unit. The upper cover assembly provided in this application allows gas (in battery cells) to be quickly discharged from the first exhaust unit and the second exhaust unit to the exhaust vent.

Upper cover assembly and battery pack

This application relates to a vehicle, a battery, and a driving apparatus, where the battery includes: a first box body; a second box body connected to the first box body; a plurality of battery units accommodated inside an enclosure defined by the first box body and the second box body; and a sealing gasket located between the first box body and the second box body whereby the first box body and the second box body are hermetically connected. The first box body and/or the second box body is provided with a first protruding portion, a side wall of the sealing gasket is provided with a notch portion, and the notch portion runs through the sealing gasket along a thickness direction of the sealing gasket, and the first protruding portion extends into the notch portion so that the first protruding portion fits with the notch portion.

Battery, driving apparatus, and vehicle

The present disclosure relates to a battery pack and transportation vehicle, wherein the battery pack includes: a box assembly; a restraint assembly disposed within the box assembly, wherein the restraint assembly is internally provided with an accommodating cavity, a first exhaust passage is provided between the restraint assembly and the box assembly, and the restraint assembly is provided with a communication hole which communicates the accommodating cavity with the first exhaust passage; and a battery module disposed within the accommodating cavity.

Battery pack and transportation vehicle

A battery pack for optimizing the structure of the battery pack includes a case, a battery module and a blocking member. The case includes an accommodating cavity and a drain hole in communication with the accommodating cavity. The battery module is contained inside the accommodating cavity. The blocking member is mounted to the case, wherein the blocking member is disposed on one side of the battery module in a width direction. At least a part of the blocking member is arranged between the battery module and the drain hole to block a binder for fixing the battery module from entering the drain hole. The reservoir cavity is provided, such that the liquid flow into a reservoir portion to prevent dangers such as short-circuit occurring in the battery module when liquid is accumulated inside the case.
