Abstract

The invention comprises a battery module. The battery module comprises a battery cell module, a partition plate module and a box body module. The battery cell module comprises a plurality of battery cells; the plurality of battery cells are suitable for being connected in series or in parallel after being stacked, and first explosion-proof valves of the battery cells are located at at least one ends of the battery cells in the length direction; the partition plate module comprises a plurality of heat insulation plates, and one heat insulation plate is suitable for being bonded between every two adjacent battery cells; the box body module comprises six sealing plates; the six sealing plates are respectively suitable for bonding six side surfaces of the battery cell module; the six bonded sealing plates are suitable for matching a plurality of heat insulation plates to form a plurality of sealed sub-mounting cavities; a plurality of second explosion-proof valves corresponding to the first explosion-proof valves are formed on the sealing plates opposite to the first explosion-proof valves; the sub-mounting cavities and the corresponding second explosion-proof valves are suitable for being sealed through sealant; and insulating layers are arranged between the first explosion-proof valves and the second explosion-proof valves and on the sealing plates. According to the battery module disclosed by the embodiment of the invention, the sealing performance is good, the battery cells can be better decompressed and protected, and the safety is high.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery module. Background technique [0002] At present, electric vehicles are grouped with multiple small modules, each of which has 3 strings / 4 strings / 6 strings, and the largest does not exceed 50 strings. However, electric vehicles often require more than 80 strings, and the optimal ones are often It is 96 strings to 108 strings, and the maximum efficiency of the motor can often be exerted at this time. A set of electric vehicle battery system needs to be assembled into the battery box according to the series-parallel connection requirements of the whole vehicle. Many small modules and other parts are assembled into the battery box. And explosion-proof pressure relief parts are added to the battery box to ensure that the battery system can be oriented and released safely when the pressure is released. However, there is a battery discharge, and when high-temperature gas ...
