Complete protection measures are set for the charge/discharge cut-off conditions in all modes for real-time monitoring of the charge/discharge test process to ensure the safety and reliability of the test process. Users can set protection thresholds flexibly, including battery pack charge/discharge cut-off voltage, maximum allowable charging current, maximum cell charge cut-off voltage, minimum cell discharge cut-off voltage, maximum cell temperature, SOC limit protection and other cut-offs conditions. When the actual operating value exceeds the threshold set by the user, the system automatically stops and issues an alarm. The log file automatically records the alarm status.
