A battery module refers to a battery cell combination module that meets the voltage and power requirements and is composed of cells in parallel and series, and then assembled with a battery management system to build a battery pack product.
The benefits of battery modules are mainly reflected in the following three aspects.
1. Better mechanical strength and protection
The battery module is equivalent to adding a protective shell to the cell, which can keep the cell in a stable state and play a role of fixed protection.
The battery module is usually composed of cells, plastic frames, pressure plates, wire harnesses, BMS slave plates, fasteners, etc. The plastic frame, insulating pads and pressure plates can play a good insulating effect.The pressure plates at both ends can not only make the cells tightly arrangement, there will also be mounting holes are connected with box fixedly , which has a good stabilization effect and improves the safety of the battery module.
2. Improve electrical performance
The battery module adopts laser welding, so the impedance of the lithium battery module is relatively small, the performance of the battery will be reduced less, and the heat dissipation performance of the module will be better, thereby improving the electrical performance.
3. Reduce after-sales maintenance costs and improve troubleshooting capabilities
There are several independent battery modules constituted a PACK system, in which BMS can monitor the condition of the cells in each module. If any one of the cells is short-circuited or faulty, the after-sales personnel can directly find the faulty module and cell. Efficiently handle faults and replace battery cells, which greatly reduces maintenance costs and is convenient and fast.
The standard module of Hongwei new energy battery adopts the soft-packed battery cell that has been independently developed and produced from material to structure for 16 years. It has better electrical performance and heat dissipation effect, and adopts automotive-grade BMS to provide one-stop battery solution.
