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.
3.
Unable to charge and discharge with red LED on. The temperature is 0~50 degree.
Use charger to charge, not possible. Use load to discharge, not possible.
g) Under permanent protection. The single cell voltage has been higher than 4.2
or lower than 1.5 or temperature higher than 80 degree.
Solution:
Switch off the module and contact your local distributor for repair.
4.
Unable to charge and discharge without red LED on. The temperature is 0~50 de
-
gree. Use charger to charge, not possible. Use load to discharge, not possible.
h) Fuse broken.
Solution:
Switch off the module and contact your local distributor for repair.
5.
Buzzer rings and all LED flash
i) High voltage protection.
Cell voltage higher than 4V or module voltage higher than 55.5V.
Solution:
Battery system requires properly established communication with
inverter and correctly settings on inverter to run safely.
Check the setting of the
inverter or charger, the charge voltage shall be 53.2~52.5Vdc; Check the commu
-
nication between battery system and inverter whether established or not; Check
the ADD switch on battery module whether is set correctly or not;
Under this condition, the BMS remains functional without damage. Just leave the
