Our main production lines exceed 6,000 square meters, with 6 independent production lines, 3 customized production lines, and 2 emergency production lines. All product raw materials are stored and inspected to comply with IEC16949 standards
SOC monitor

Grading System

We use brand-new A-grade cells from well-known brands including Gotion, EVE, Sunwoda, CATL, Ganfeng, etc. to make battery packs. Before official use, we will do a capacity test. After the test is completed, it can be put into storage and used.

Sample Workshop

We will conduct small-scale sample testing before mass production to verify product reliability, including thermal runaway, charge and discharge, waterproofing, over-discharge, etc., and use data to verify the performance of the battery pack.
Automatic Welding Machine

Laser Welding

We will use laser welding machines to produce standard modules. This method can greatly increase the welding strength, avoid false welding and possible looseness in the future, and also improve production efficiency.
