Alarm and abnormality handling
When the ALM alarm red light on the front panel of the battery flashes or stays on, the battery is in alarm
or protection. Please refer to Table 3-6 in Chapter 3 to verify the current trigger state of the battery.
Usually when the battery arises an "alarm" indicator, it means that the battery is running under relatively
critical conditions but still operate normally; when the
“protection” indication appears, it means that one or
more parameters of the battery have reached the protection threshold, the BMS will cut off the
corresponding MOS to ensure the safety of battery. After the related parameters falls back, the battery will
automatically return to normal use.
