Battery PACK Production Line & Turnkey Assembly Solution
- One supplier
- Full responsibility
- Zero risk
Overview of Our Battery PACK Manufacturing Line
At Xiaowei New Energy, we design and build automatic battery pack production lines engineered for the full spectrum of lithium-ion applications — from EV battery packs to energy storage systems (ESS), UPS, and general-purpose lithium batteries.
Our turnkey PACK manufacturing solutions integrate every stage — cell sorting, module welding, BMS installation, performance testing, and final packaging — ensuring reliability, traceability, and scalability.
The PACK line can be seamlessly integrated with our Battery Cell Production Line, offering a one-stop cell-to-pack solution for customers building complete lithium battery factories.

Automated Battery PACK Production Process
The Battery PACK production process is generally divided into three main sections: Cell Test & Load, Battery Module Assembly, and Battery PACK Assembly.
Each stage transforms individual battery cells into complete PACK systems through precise, automated operations.
Depending on the cell type — cylindrical, prismatic, or pouch — and the target application, the process and technical requirements may vary.
The following five steps outline the standard workflow of a Battery PACK Production Line:
1. Cell Sorting & Grading
Automatic cell sorting by voltage, internal resistance, and capacity ensures only matched cells enter the PACK assembly. This step maximizes consistency and performance across each battery pack.
2. Module Assembly
Cells are grouped and stacked into modules using precision alignment and welding systems. Compatible with cylindrical, prismatic, and pouch cells, the system achieves high throughput and stable yields.
3. PACK Welding & BMS Integration
Each module is connected via laser or ultrasonic welding, followed by the installation and testing of the Battery Management System (BMS). Full data traceability and MES connectivity guarantee quality control.
4. Performance Testing & Aging
Every PACK undergoes performance, safety, and ageing tests, including voltage, capacity, and thermal evaluation. Automated testing benches and ageing chambers ensure long-term stability.
5. Final Assembly & Packaging
The final stage integrates enclosure assembly, labeling, and automatic conveyor packaging, preparing each pack for safe shipment or downstream installation.
If you are planning a turnkey pack production project, our team can design, build, and deliver a fully integrated line tailored to your capacity, budget, and product requirements.
