Abstract: A casing for a battery pack includes a cross beam. The cross beam includes a top surface. The top surface defines a mounting groove configured to mount an output electrode base. A battery pack including the casing, and a vehicle including the battery pack are also provided.

Abstract: A battery cooling system provided by the present disclosure includes a crossbeam and a cooling assembly. The crossbeam defines an avoidance groove, the avoidance groove extends in a length direction of the crossbeam, and the avoidance groove is configured to mount the cooling assembly.

Abstract: A pressure relief device includes a gas-permeable membrane, a valve body, an elastic seat assembly, a protective cover and a baffle. The gas-permeable membrane is arranged at a side of the elastic seat assembly. The valve body is located at a side of the elastic seat assembly close to the gas-permeable membrane. The protective cover covers a side of the valve body away from the gas-permeable membrane. The elastic seat assembly is located between the valve body and the protective cover, and movable towards the protective cover to define a gas discharge channel or movable away from the protective cover to close the gas discharge channel. The baffle is arranged at a side of the gas-permeable membrane away from the elastic seat assembly. A reserved gap is arranged between the baffle and the gas-permeable membrane, and between the gas-permeable membrane and the elastic seat assembly.

Abstract: The present disclosure provides a Redis Key management method, for managing and controlling Redis Keys generated by a same task in a streaming framework, the Redis Key management method including: packaging the Redis Keys generated by the same task and storing packaged Redis Keys in a same Key bucket; performing a duplicate-removal processing on Redis Keys in the same Key bucket for being called by external data; and performing a batch deletion on Redis Keys after being called by external data. In the present disclosure, Redis Keys in the same task and located in the same partition may be stored in a Key bucket. Key buckets may be located. Duplicate-removal processing may be performed on the Redis Keys in the same Key bucket so that the Redis Keys can be called by external data. A batch deletion may be performed on the Redis Keys after being called by external data.
