Disconnected Battery Group Power Line Detection in Battery Stack
Explanation:
The system has detected a faulty power cable connection (e.g., abnormal voltage measurement, sudden change in loop impedance) between a specific battery cluster in the battery stack and the power conversion system (PCS). The energy of this cluster cannot be transferred normally. As a result, the system has entered an error state to ensure the safety of the devices.
Corrective measures:
Perform a system shutdown to ensure the device is switched off. Never perform work on live electrical circuits.
Check all cable connections between the battery cluster and the DC Combiner Box, as well as between the DC Combiner Box and the PCS, one after the other. Make sure they are securely in place and show no signs of loosening or burning.
Inspect the entire power cable for obvious physical damage, crushing, breaks, and damage to the insulation layer.
Tighten any loose connections and replace damaged cables to ensure all connections are secure and reliable.
Restart the system after completing the repairs and checks. The error will be cleared automatically.
