Quality control

Six-stage factory acceptance process

Every production batch passes traceable electrical, mechanical and functional checks.

100% batch traceability
Stage 01

Cell OCV and resistance screening

Cells are grouped by voltage and internal resistance before assembly.

Stage 02

Robotic laser welding

Busbar joints are welded and checked for consistency.

Stage 03

BMS firmware calibration

Protection thresholds and communication protocols are configured.

Stage 04

−40 °C chamber test

Selected batches are validated under extreme-cold conditions.

Stage 05

72-hour aging test

Charge, discharge, balancing and protection functions are monitored.

Stage 06

Final inspection and packaging

Electrical function, documentation and export packaging are checked.
