Liquid-cooled Energy Storage System

Verify all incoming cell parameters to ensure they meet quality standards and determine whether the cells are suitable for subsequent production.

Test and classify cells based on open-circuit voltage (OCV) and internal resistance parameters.

Remove dirt, dust, and surface impurities from cells to ensure a clean surface condition for assembly.

Stack cells in sequence to form modules, apply compression, and install steel bands at the top and bottom of the module.

Install insulated busbar plates onto the module, then perform laser welding and inspect weld quality.

Assemble sampling wire harnesses sequentially, perform laser welding, and conduct visual inspection to ensure welding and assembly quality.

Conduct performance testing on the module to evaluate whether it meets all required technical specifications.

Pre-process components including the connector mounting plate, maintenance cover seal strips, and mounting brackets.

Clean the battery enclosure to remove dust, debris, and other contaminants, keeping both the interior and exterior clean.

Place the module into the enclosure and arrange the wire harnesses neatly to ensure an orderly layout.

Conduct end-of-line testing to verify overall performance and ensure compliance with product standards.

Position and install the top cover securely to complete final assembly.

Perform airtightness testing on the enclosure to verify sealing integrity, followed by final offline product inspection to confirm full compliance with release criteria.
