No
Problem
Possible Reason
Solution
1
Turn on the BMS. All battery
modules’ status LED is not
working.
l
The
DC/DC
power
board or control board
is failure.
l
The
communication
cable from BMS to the
first battery module is
broken
l
Power cable is broken;
l
Change the control
module (BMS module).
l
Change the broken
communication cable;
l
Check all the power
cables and connections
are fine or not;
2
Turn on the BMS. The Status
LED for BMS is not working.
But all battery modules’
status LED is lighting green.
l
The control board is
failure.
l
Change the control
module (BMS module).
3
Turn on the BMS. The Status
LED is lighting red. But all
battery modules’ status LED
is lighting green.
l
This battery string is
under protection. It is
possible Over Current
Protection or Failure
Protection.
l
No
external
communication
with
upper controller;
l
Battery String is reversed
connection.
l
Through the monitor or
maintenance
software
check the battery cell,
battery
module
has
alarm or not.
l
Check communication
with upper controller and
communication
cable
wiring;
l
Reversed connection is
serious danger!
4
The BMS’s Status LED is
lighting red and some the
battery module’s status
LED is lighting green but
some is lighting red.
l
This battery string is
under protection. It is
possible Over Current,

Voltage,
Low
Voltage,
Over
Temperature,
Low
Temperature or Failure
Protection.
l
Use the monitor or
