Testing Before Release
A battery is not ready when assembly ends. Testing connects manufactured packs to the actual operating conditions agreed with the buyer. Our release workflow verifies each unit as a reliable electrical product, a BMS-controlled system, and an outdoor-ready energy storage order.
High and Low Temperature Testing
Simulate extreme ambient temperatures to verify cell thermal stability and enclosure durability under severe climatic conditions.
BMS Test Equipment
Verify multi-fault protection logic and validate real-time communication protocols under simulated limits.
Waterproof Test Area
Conduct rigorous water spray and sealing tests to confirm outdoor enclosures satisfy required IP protection ratings.
Battery Cell Testing
Measure incoming cell capacity, voltage curves, and internal resistance to maintain consistent electrical performance.
HV Battery Test Equipment
Perform high-voltage insulation and withstand testing to safeguard commercial and industrial energy storage systems.
Inverter Test Area
Execute closed-loop operational verification with mainstream hybrid inverters to confirm protocol handshake compatibility.
