Sample Workshop

The semi-automated sample production workshop allows rapid customization through quick prototype assembly, preliminary thermal simulation, and thermal runaway testing, ensuring visible, quality-controlled outcomes.
Automatic Welding Machine

Laser Welding

Before mass production, welding diagrams are prepared in advance. Cells and copper bars are accurately arranged and then placed into the automated laser welding machines.
capacity test

Aging Room

After production, a comprehensive charge and discharge test is performed, recording capacity, charge/discharge rates, and temperature data for future traceability.
12V 100Ah series testing

SOC Calibration

Before shipment, all battery packs of the same batch are voltage-tested against their discharge curves to ensure uniformity at 55% SOC, preventing excessive discharge during sea transport.
