QUALITY CONTROL

Quality Control Throughout Production and Final Testing

We combine production monitoring, critical process inspections and test result reviews throughout energy storage manufacturing. Key quality data recorded through MES, together with reviews by trained personnel, support product consistency, traceability and continuous improvement.

01

Production Process Monitoring: MES monitors key quality data and critical processes during battery pack production in real time, helping production and quality teams track manufacturing performance and maintain process control.

02

Critical Process Inspections: Battery packs and associated components undergo CCS inspections, end-of-line (EOL) testing, leak testing and fastening torque checks. Trained personnel review the results to support assembly quality verification and product release.

03

Quality Records and Traceability: Records of critical processes and test results support production reviews, quality investigations and after-sales service, providing a documented basis for quality management.

04

Analysis and Continuous Improvement: Production monitoring data and test records provide a basis for investigating quality issues, refining manufacturing processes and assessing improvements to production consistency and delivery quality.
