Problems solved by technology

[0003] However, this will cause the heat generated by the battery module in the box to be unable to be discharged out of the box smoothly, causing the temperature inside the box to rise, thereby bringing safety hazards to the rechargeable battery pack
Secondly, because the battery module is formed by fixing multiple battery cells through welding frames, the size of the entire battery module is unstable and the weight is relatively large. Assembly brings difficulties, reduces assembly efficiency, and is not conducive to the individual replacement of battery cells, that is, the damage of one battery cell will cause the entire battery module to be unusable. Therefore, it is not conducive for maintenance personnel to quickly replace the battery module group, the maintenance cost is relatively high

Abstract

An embodiment of the invention provides a battery pack which comprises at least two battery cell units, a BMS (battery management system) control component and a shell. The battery cell units and the BMS control component are arranged in the shell, each battery cell unit is electrically connected with the BMS control component which comprises a protecting shell and an electroconductive structure extending out of the protecting shell, and an electronic element of the BMS control component is sealed in the protecting shell. The battery pack is easy in heat radiation, protecting grade of the shell of the battery pack can be lowered without lowering safety grade of the battery pack, assembling difficulty is lowered, production efficiency is improved, and convenience is brought to subsequent maintenance of the battery pack and replacement and repairing of the battery cell units.

Description

【Technical field】 [0001] The invention relates to the technical field of batteries, in particular to a battery pack. 【Background technique】 [0002] Electric vehicles are vehicles that use rechargeable battery packs to drive the wheels. They are favored by low- and middle-income groups because of their low price, convenience, and environmental protection. The rechargeable battery pack generally includes a cell module, a BMS control module, and a box for accommodating the cell module and the BMS control module. In order to ensure the safety of the battery module and the BMS control module, the structural strength of the box used to package the battery module and the BMS control module is very high, so as to achieve the purpose of strengthening the protection level. [0003] However, this will cause the heat generated by the battery module in the box to be unable to be discharged out of the box smoothly, which will cause the temperature inside the box to rise, thereby bringin...
