Possible conditions:
1.
Battery cannot turn on, switch ON and press the red SW the lights are all no lighting
or flashing.
a) Capacity too low, or module over discharged.
solution: use a charge or inverter to provide 48-53.5V voltage. If battery can start,
then keep charge the module and use monitor tools to check the battery log.
If battery terminal voltage is ≤45Vdc, please use ≤0.05C to slowly charge the mod
-
ule to avoid affect to SOH.
If battery terminal voltage is >45Vdc, it can use ≤0.5C to charge.
If battery cannot start, turn off battery and repair.
2.
The battery can turn on, but red light is lighting, and cannot charge or discharge.
If the red light is lighting, that means system is abnormal, please check values as
following
b) Temperature: Above 60
°C
or under -10
°C, the battery could not work.
Solution: to move battery to the normal operating temperature range between 0
°C
and 50
°C.
c) Current: If current exceeds 90A, battery protection will turn on.
Solution:
Check whether current is too large or not, if it is, change the settings on
power supply side.
d) High Voltage: If charging voltage above 54V, battery protection will turn on.
Solution:
Check whether voltage is too high or not, if it is, to change the settings
on power supply side. And discharge the module.
e) Low Voltage: When the battery discharges to 44.5V or less, battery protection
will turn on.
Solution:
Charge the battery till the red light turns off.
f) Cell voltage high. The module voltage is lower than 54V, SOC LED does not all
on. When discharge the module protection disappear.
Solution:
keep charge the module by 53-54V or keep the system cycle. The BMS
can balance the cell during cycling.
