How Lithium Battery Packs Are Manufactured: Step-by-Step Process

Lithium battery packs are widely used in electric wheelchairs, medical equipment, industrial devices, and mobility applications. But how exactly are these battery packs manufactured? This article walks you through the key steps of the lithium battery pack production process.

1. Battery Cell Selection

The manufacturing process starts with selecting suitable lithium battery cells. Different applications require different cell types, capacities, discharge rates, and cycle life characteristics.

Choosing consistent and reliable cells is critical to ensuring battery safety, performance, and long-term stability.

2. Battery Pack Design

Engineers design the battery pack based on voltage, capacity, physical size, and application requirements. This includes cell configuration (series and parallel), mechanical structure, wiring layout, and connector selection.

3. BMS Integration

A Battery Management System (BMS) is integrated to protect the battery pack from overcharge, over-discharge, overcurrent, and short circuits. The BMS also helps balance cell voltage to extend battery life.

4. Assembly and Welding

Cells are assembled and connected using spot welding or laser welding. Proper welding strength and consistency are essential to ensure electrical stability and vibration resistance.

5. Testing and Quality Control

Before shipment, each battery pack undergoes multiple tests, including voltage inspection, capacity testing, aging tests, and safety checks.

At GEB Power, strict quality control procedures are applied at every production stage to ensure reliable performance.

Conclusion

A well-manufactured lithium battery pack is the result of careful design, precise assembly, and thorough testing. Understanding this process helps customers choose a safe and dependable battery solution.
