Technical parameter：

How does the battery management system in ESS protect against short circuits?

Identify short-circuit situations.

• Current detection:The BMS identifies short-circuit conditions by continuously monitoring the current changes of the battery pack. When an abnormally high current is detected, a short circuit may have occurred.

• Voltage monitoring:In the case of a short circuit, the voltage of the affected battery cell or the entire battery pack may suddenly drop. The BMS identifies this abnormal situation through vltage monitoring.

• Temperature monitoring:A short circuit will cause a sharp rise in local temperature. The BMS detects abnormal temperature rises through temperature sensors to determine whether a short circuit has occurred.

Implement protection measures.

• Cut off power supply:When a short circuit is detected, the BMS will immediately cut off the connection between the battery pack and the external circuit through relays or switches to prevent the current from continuing to flow and avoid excessive discharge or heating of the battery.

• Alarm and record:Trigger the alarm system to send a warning signal to the operator and record relevant information such as the time and location of the short circuit occurrence for subsequent investigation and handling.

• Isolate faulty units:If the short circuit occurs in a certain battery cell rather than the entire battery pack, the BMS can isolate the cell to prevent it from affecting other normal battery cells.
