Problems solved by technology
[0002] In related technologies, power battery modules mostly use multi-plate or upper and lower shell assembled battery housing components. Although this structure can better protect the battery, due to the structural limitations of the multi-plate structure and the upper and lower shell structure, The battery combination method cannot be freely expanded. When the battery combination method changes, it needs to be redesigned and developed, which greatly increases the time and cost of project development. At the same time, the above two structures are not conducive to the automatic production of power battery modules. Increase the production cost of the power battery module, making the product lose its competitive advantage
In addition, the separators used for power battery modules in the related art have the defects of low safety performance and inconvenient disassembly and assembly, and there is room for improvement

The invention discloses a septum for a power battery module, a battery containing assembly and a power battery module. The septum for the power battery module comprises a septum body, a left cover plate and a right cover plate, wherein the septum body has a front side surface and a rear side surface which are opposite to each other, a front battery containing slot is formed in the front side surface, the left cover plate is arranged at the left end of the septum body, and the right cover plate is arranged at the right end of the septum body. According to the septum for the power battery module, disclosed by the embodiment of the invention, by arranging the left cover plate at the left end of the septum body and arranging the right cover plate at the right end of the septum body, the left cover plate and the right cover plate can be utilized for playing a role in protecting the septum and a battery inside the septum, so that the security and reliability of the power battery module are improved, and multiple split type left cover plates and right cover plates are arranged at the end of a battery pack, so as to facilitate the disassembling and assembling of separate battery cells of the battery pack.
Description
technical field [0001] The invention relates to the field of batteries, in particular to a separator for a power battery module, a battery containing assembly having the same, and a power battery module having the battery containing assembly. Background technique [0002] In related technologies, power battery modules mostly use multi-plate or upper and lower shell assembled battery housing components. Although this structure can better protect the battery, due to the structural limitations of the multi-plate structure and the upper and lower shell structure, The battery combination method cannot be freely expanded. When the battery combination method changes, it needs to be redesigned and developed, which greatly increases the time and cost of project development. At the same time, the above two structures are not conducive to the automatic production of power battery modules. The production cost of the power battery module is increased, and the product loses its competitiv...
