Core Technologies
1. Lightweight and Scalability

We systematically optimize cell design and electrical component selection. We utilize lightweight steel/aluminum alloys and high-strength plastics for the battery box and pack structure to reduce volume and weight, combined with CAE structural simulation to ensure strength and energy density.

2. Thermal Management and Simulation Design

Our capabilities include CFD simulation (Computational Fluid Dynamics) and CAE simulation (Computer Aided Engineering). We design thermal management systems using air cooling, liquid heating/cooling, and PI film heating to optimize performance.

Thermal Management
3. Test and Verification

Verification is conducted at DV/PV stages, including temperature tests, mechanical tests, external environment simulations, electrical safety, and battery performance tests to ensure all requirements are met.
