1. Monitoring battery working status
2. Battery charge and discharge management
3. Cell balancing
low speed electric car, electric motorcycle, electric tractor, etc
a. The cells we use are domestic high-quality cellsfrom China big cell manufacturers or imported cells from Sumsang, Panasonic.LG, etc .
b. BMS are realiable. BMS within 24S, we develop by ourselves. BMS above 24S, we purchase from China top 3 BMS manufacturers.
c. Advanced battery pack assembly technologies ensures the finished battery packs are of high quality.
a- Good Quality Management:
Mass production base has passed TS16949 Quality System, ISO14001 Environmental System and OHSAS18001 system certifications. And we have passed the test of the National Motor Vehicle Product Quality Supervision and Inspection Center. We always do daily production as per these systems.
b- Advanced hardware and software facilities
We established high-precision three-coordinate measuring machines, projectors, universal material tensile machines, and other measuring instruments to ensure the effective quality data.
c- Technical advantage:
Our technical team are all from China famous electric vehicle manufacturers. They all have more than 10 years' industry experiences. They have excellent R&D abilities. We also have the ability to develop BMS by ourselves.
