5. Trouble shooting
NOTE: Checkpoints
1. Whether the battery can be turned on or not.
2. If battery is turned on, check the red light is off, flashing or lighting.
3. If the red lights is off, check whether the battery can be charged/discharged or not.
Battery cannot turn on, switch on and press the metal SW the lights are all no
lighting or flashing.
o Capacity too low, or module over discharged.
Solution:
then keep charge the module and use monitor tools to check the battery
log.
o If battery terminal voltage is ≤2.8V/cell, please use ≤0.05C to slowly charge the
module to avoid affect to SOH.
o If battery terminal voltage is >2.8V/cell, it can use ≤0.5C charge.
o If battery cannot start, turn off battery and repair.
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.
o Temperature: above 60°C or under -10°C, the battery could not work.
Solution:
between 0°C and 50°C.
o Current: if current exceeds 100A, battery protection will turn on.
Solution:
settings on power supply side.
o High voltage: If charging voltage is over 3.65V per cell, battery protection will
turn on.
Solution:
settings on power supply side and discharge battery.
o Low voltage: when the battery discharges to 2.75V/cell or less, battery
protection will turn on.
Solution:
o Cell voltage is high.
Solution:
The BMS can balance the cell during cycling.
Unable to charge and discharge with red LED on. The temperature is 0~50°C. Use
charger to charge, not possible. Use load to discharge, not possible.
o Under permanent protection. The single cell voltage has been higher than 3.8
or lower than 2.0 or temperature higher than 80°C.
Solution:
repair.
Unable to charge and discharge without red LED on. The temperature is 0~50°C. Use
charger to charge, not possible. Use load to discharge, not possible.
o Fuse broken.
Solution:
repair.
use mains or inverter to charge battery. If battery can start,
to move battery to the normal operating temperature range
check whether current is too large or not, if it is, change the
check whether voltage is too high or not, if it is, to change the
charge the battery till the red light turns off.
keep charging or keep the system cycle.
