The battery string’s system will check itself, if work normal the battery string system will go to self-
check mode.
If the BMS and all battery modules are working normally, every status LED will lighting green, that’s
mean self-check are pass. Normally the self-check will be finish within 30sec.
Black-start function:
If long press(>5sec) the start button 30s AFTER power on. The“STATUS” lamp will becomes green if
the black start function is enabled. If “STATUS” lamp remain red, the black start function is failed
to active, need long press start button again. System will close relay and output for 10mins.
If MBMS is using internal power supply from BMS, after all BMS powered on please first use black
start function to provide power supply to MBMS, for further establish the external communication.
If there is no communication from upper equipment because of the communication is off, the
“STATUS” lamp will light red after 30sec. That doesn’t means failure existed, it means this battery
string is OK while the external communication is off.
