Product Detail

Productive Process

1. Cell Screening
Testing and selecting lithium-ion cells with consistent voltage, capacity, and impedance to ensure uniformity.

2. Cell Series Connection & Welding
Electrically connecting cells in series via laser welding or ultrasonic bonding to achieve desired voltage.

3. Battery Pack Assembly
Grouping welded cells into modular packs with integrated BMS, thermal management, and structural framing.

4. Cluster Integration
Combining multiple battery packs into a high-voltage cluster (e.g., 1500VDC) through busbars and safety disconnects.

5. Aging Test
Cycling clusters under controlled conditions to weed out early-life defects and stabilize electrochemical performance.

6. Compatible Test Containerization
Test the compatibility between the battery and the PC, then installclusters into ISO containers with PCS, HVAC, and fire suppression, followed by grid-simulation testing.
