Problems solved by technology
At present, in most battery packs, the parallel connection and series connection of battery cells and battery modules are connected by spot welding or wire connection. These methods can make the battery pack achieve better reliability, but the welding process and production time , procedures and costs are very high, and once a single cell in the battery module fails, the entire battery module must be replaced, resulting in a great waste, and at the same time, when the battery pack is maintained, the work of disassembling the battery module will also very cumbersome and time consuming

The invention discloses an assembled battery module and a battery pack thereof. The battery pack includes a plurality of battery modules composed of battery cells, fixing brackets and conductive sheets. The longitudinal direction of the module has a series connection between two adjacent battery modules. The conductive connecting piece and the longitudinal connecting rod and locking eccentric wheel for positioning and pressing the battery module. In the lateral direction of the module, there are conductive connecting pieces for connecting two adjacent battery modules in parallel or in series and a dovetail shape for positioning and pressing the battery module. Guide rail pairs and transverse connecting rods, and a connection method between the plug-in power output interface and the battery pack and a vibration-damping connection method between the battery pack and the bottom plate of the battery pack box are designed. The invention can realize the modularized production mode of the battery pack, and the required battery pack can be formed by the connection between the modules only by simple splicing. Compared with the traditional spot welding process connection, the processing and production of the battery pack is reduced Time and process, improve production efficiency.
Description
technical field [0001] The invention relates to an assembled battery module and a battery pack thereof. Background technique [0002] With the increasing application of power batteries in automobiles and other fields, more and more types of management modes and assembly methods of power batteries have emerged. In the current mainstream power batteries, most of the power battery cells are assembled into a battery module, and the battery management system is designed with the module as the basic unit. It can be seen that the battery module is the most basic component of a battery pack. At present, in most battery packs, the parallel connection and series connection of battery cells and battery modules are connected by spot welding or wire connection. These methods can make the battery pack achieve better reliability, but the welding process and production time , procedures and costs are very high, and once a single cell in the battery module fails, the entire battery module m...
