Battery assembly
Battery assembly is a key step to synthesize a single battery pack into a battery pack in the production process of lithium batteries. Firstly, the cell parameters in the battery pack are consistent by screening and matching the battery cells with the same performance. Then, the single battery is assembled into modules by welding or connecting pieces, and the protection circuit and battery management system (BMS) are integrated to ensure the safety and stability of the battery pack. The housing package and assembly fixing provide physical protection of the battery pack to ensure stable operation in harsh environments.

Main steps
Objective: To select a battery cell with the same performance to ensure the internal balance of the battery pack.
Procedure:
According to the capacity, internal resistance, voltage and other parameters, the single battery was secondary screened and grouped.
Group batteries with similar performance to avoid failure caused by overcharge or overdischarge or capacity difference.
Significance: Improve the overall performance and cycle life of the battery pack.
Purpose: According to the design requirements, the battery cells are combined into modules to provide the basis for subsequent battery assembly.
Procedure:
A plurality of single batteries are connected into modules by welding or connecting pieces.
A fixed structure is designed in the module, such as a metal frame or insulating material bracket, to ensure the mechanical strength and thermal stability of the module.
Significance: The modular design facilitates large-scale assembly and improves the ease of maintenance and replacement.
Objective: To provide monitoring and protection functions for the battery pack to ensure the safety and efficiency of operation.
Procedure:
Integrated protection circuits (such as overcharge, overdischarge, overcurrent, short circuit protection) to prevent damage to the battery pack under abnormal conditions.
Equipped with a battery management system (BMS) to monitor the temperature, voltage, current and balance of the battery pack to optimize performance.
Significance: The BMS system can improve the safety and energy efficiency of battery packs.
Objective: To protect the internal structure of battery pack and prevent the influence of external environment on its performance.
Procedure:
The battery pack is encapsulated in a metal or plastic housing to provide dust, water, and collision protection.
Add cushioning material or insulation to the inside of the housing for added security.
Significance: Enhance the physical protection ability of the battery pack to ensure its stability in harsh environments.
