Technical Excellence

Cell-to-Pack BESS AGV Line

The Cell-to-Pack BESS AGV Line Process Flow developed by Semco Infratech is designed to deliver efficient and automated production for modern Battery Energy Storage System (BESS) applications. The process begins with cell processing, where battery cells undergo automatic feeding, OCV and internal resistance testing, thickness measurement, sorting, polarity adjustment, and adhesive application to ensure only qualified cells move forward. In the module stacking stage, cells are arranged using automated equipment and secured with steel strip installation for structural stability. Next, during module assembly, stacked modules are transferred through a buffer system, inserted into the pack box, and fixed securely for further integration. The pack box preparation stage includes liquid cooling plate installation, air-tightness testing, and glue application with inspection to ensure proper thermal management and sealing. After that, pack processing integrates safety and electrical systems through insulation testing, engraving and scanning for traceability, terminal cleaning, pole-based addressing, and CCS placement. The line then performs robotic laser welding, providing precise electrical connections followed by post-welding cleaning and inspection. Finally, in the final assembly and testing stage, the system installs the front panel and copper busbars, conducts end-of-line testing, secures the box lid, integrates fire protection and BMS, and performs a pack air-tightness test before the battery pack exits the line ready for energy storage deployment.

Cell-to-Pack Battery Energy Storage System (BESS) AGV Line

Cell-to-Pack BESS AGV Line Process Flow

1. Cell Processing

The first stage focuses on preparing battery cells for module assembly while ensuring quality control and accurate sorting.

Key processes include:

  • Automatic Cell Feeding & AGV Feeding

  • OCV / Internal Resistance Testing

  • Cell Thickness Measurement

  • Cell Sorting

  • Polarity Adjustment

  • Cell Adhesive Application

These steps ensure only qualified cells move forward into module stacking, improving pack consistency and performance.


2. Module Stacking

In this stage, prepared cells are arranged and structured into battery modules.

Processes involved:

  • Module Pre-Stacking

  • Steel Strip Installation

The stacking process ensures mechanical stability and proper electrical connectivity between cells.


3. Module Assembly

After stacking, modules are transferred into the pack enclosure for further integration.

Assembly steps include:

  • Module Buffer Handling

  • Module Placement into Box

  • Module Fixation

This stage prepares the modules for integration with cooling systems and pack electronics.


4. Pack Box Preparation

Before module integration, the battery pack housing undergoes preparation and inspection.

Preparation processes:

  • Liquid Cooling Plate Installation

  • Liquid Cooling Plate Air-Tightness Testing

  • Box Assembly Glue Application & Inspection

These steps ensure proper thermal management and sealing performance, which are essential for energy storage battery packs.


5. Pack Processing

This stage integrates electrical connections, identification systems, and safety features.

Key operations include:

  • Insulation Testing

What is a Cell-to-Pack BESS AGV Line?

A Cell-to-Pack BESS AGV Line is an automated battery manufacturing system that directly integrates battery cells into battery packs using AGV-based material handling, robotic welding, and advanced testing technologies to improve efficiency and production speed.

A Cell-to-Pack BESS assembly line offers several advantages including higher energy density, reduced production complexity, improved manufacturing efficiency, and lower battery pack costs for energy storage systems.

Automated Guided Vehicles (AGVs) transport battery modules, pack components, and materials between different production stations, ensuring efficient workflow, reduced manual handling, and improved factory automation.

Robotic laser welding provides high-precision electrical connections, strong weld quality, and minimal thermal impact on battery cells, making it ideal for lithium battery pack assembly.

What testing processes are included in a BESS assembly line?

A typical BESS assembly line includes OCV testing, internal resistance testing, insulation testing, air-tightness testing, and end-of-line (EOL) testing to ensure battery safety, performance, and reliability.

Battery Energy Storage System packs are widely used in renewable energy storage, solar and wind power integration, grid stabilization, industrial power backup, and EV charging infrastructure.

The Cell-to-Pack architecture eliminates intermediate modules, allowing more cells to fit inside the pack, which increases energy density, improves thermal management, and reduces manufacturing costs.

The Cell-to-Pack BESS AGV Line from Semco Infratech is designed for high-speed manufacturing and can produce up to 16 battery packs per minute (16PPM), making it ideal for large-scale Battery Energy Storage System (BESS) production.
