Abstract

The invention provides a fixing device of a battery cell in a battery pack and a battery pack. The fixing device of the battery cell in the battery pack comprises a housing, a pressing plate and a pressing block. A fixing boss is disposed in the housing. The pressing plate is disposed on at least one side of the fixing boss. The pressing block is connected to the fixing boss. The connection matching length between the pressing block and the fixing boss is adjustable. By changing the connection matching length between the pressing block and the fixing boss, the pressing block can push the pressing plate in order that the pressing plate is pressed against the battery cell. Therefore, by the cooperation of the housing, the pressing plate and the pressing block, the battery cell in the batterypack can be pressed, the battery cell can be directly formed into the battery pack, and the side plate structure of a battery module in the battery pack can be eliminated. Thus, the weight of the battery pack is reduced. Further, a soldering step of the end plate and the side plate of the battery module can be eliminated, the process difficulty of manufacturing the battery pack can be reduced, and the assembly efficiency of the battery pack can be improved.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a fixing device for electric cores in a battery pack and a battery pack with the fixing device for electric cores in the battery pack. Background technique [0002] With the country's vigorous promotion and support for the new energy field, the development of electric vehicles is becoming more and more rapid. As the core component of electric vehicles, the battery pack is particularly important to reduce the weight of the power battery pack and simplify the components. They have a positive effect on the cruising range, safety, and reliability of electric vehicles. [0003] In related technologies, the components of the current power battery pack are modules. Due to the difficult assembly process of the module itself and the side plate structure, the side plate needs to be welded to the end plate, so the overall assembly process is complicated and the battery pack is heavy.
