Abstract

The invention provides a partition plate for a battery module, the battery module, a battery pack and an electric vehicle. The partition plate comprises at least two blocking pieces, a pressure bearing piece is arranged between every two adjacent blocking pieces, and each pressure bearing piece comprises a body and an insulating layer arranged on the outer wall of the body. On the premise that the current volume utilization rate is not affected, the number of fixing points in the battery module is increased, the mechanical connection strength of the module is improved, the volume of the battery module is increased, meanwhile, the battery module is fixed without relying on glue bonding, and the maintenance problem in a current high-integration battery pack is solved.

Description

technical field [0001] The invention belongs to the technical field of batteries, and relates to a separator for a battery module, a battery pack and an electric vehicle. Background technique [0002] At present, power battery modules generally have a low grouping rate. In response to this situation, most battery factories have introduced solutions to increase the grouping rate, but most of the solutions make the modules lose their replaceable features and increase after-sales costs. Many current high-composition methods rely too much on battery packs spliced ​​with aluminum alloy profiles, which increases the manufacturing cost of battery packs. [0003] CN212934720U discloses a power lithium battery module, including a power battery module end plate, a power battery template heating assembly, an insulating partition, a power battery cell, a power battery module busbar, a busbar insulating plate and a battery module protection Cover; the end plates of the power battery mod...
