Answer：The BMS has a fault warning function, which can be viewed via the host software. Faults include the following：
1)Sampling fault: a fault in the communication between the analogue front end and the master chip. When this fault occurs, the charging and discharging MOS is switched off and the fault alarm can be cleared automatically when the fault is cleared;
2)Temperature NTC failure: mainly detects if the temperature NTC is short-circuited or disconnected. When this fault occurs, the charging and discharging MOS is switched off and the fault alarm is automatically cleared when the fault is cleared;
3)The fault is also reported when the voltage sampling line is disconnected. The fault alarm is cleared automatically when the fault is cleared.
