⚙️ Core Technologies
1. Lightweight and Scalability

The system optimizes cell design and electrical component selection. Using the lightest steel/aluminum alloys and high-strength plastics, combined with CAE structural simulation, we ensure structural strength while improving energy density. Standardized modules (12V-72V) allow for excellent scalability to meet diverse requirements.

Scalability Technology
2. BMS and Active Balance

Equipped with an advanced BMS supporting passive balance by default, with an option for active balance. Parameters such as CAN/RS485 protocols, over/under voltage, high current, and temperature protection can be customized on-site.

BMS System
3. Thermal Management and Simulation

Utilizing CFD (Computational Fluid Dynamics) and CAE simulation, the system incorporates advanced thermal management including air cooling, liquid heating/cooling, and PI film or silica gel film heating to maintain optimal operating temperatures.

Thermal Simulation
4. Test and Verification

Rigorous DV/PV (design/production verification) testing is conducted, including temperature tests, mechanical tests, external environment simulation, electrical safety, and abuse testing to ensure full compliance with design requirements.
