lights are all no lighting or flashing.
a) Capacity too low, or module over discharged.
solution: use a charge or inverter to provide 48-56.8V
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 module 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 the battery cannot be charged
or discharged.
Temperature
a) Above 60℃ or under -10℃, the battery could not work.
Solution:
temperature range between 0℃ and 50℃
Voltage, SOC
b) Low Voltage: When the battery discharges to 45V or less,
battery protection will turn on.
Solution: Charge the battery till the red light turns
off.
c) Cell voltage high. The module voltage is lower than 56V,
SOC LED does not all on. The module protection disappears
when discharge.
Solution: keep charge the module by 55-56V or keep the
system cycle. The BMS can balance the cell during cycling.
d) High Voltage: If charging voltage above 57V, battery
protection will turn on.
