battery is turmed on, check the red light is o, fiashing or lighting;3) If the red light is
o, check whether the battery can be charged/discharged.
Preliminary determination steps:1) Battery cannot be turned on, switch on the lights
are all no lighting or flashing. If the battery extemal switch is ON, the RUN light is
flashing, and the external power supply voltage is51.2vor more, the battery still
unable to turn on, please contact distributor.
- The battery can be tumed on, but red light is lighting, and cannot be charged or
discharged, red light is lighting, that means system is abnormal, please check
values as following.
- Temperature: Above 50C or under-10C, the battery could not work. Solution: to
move battery to the norma operating temperature range between-10C and 50C.4)
Current: If current is larger than 100A, battery protection will tur on.Solution: Check
whether current is too large or not, if it is, to change the settings on power supply
side.
- High Voltage: If charging voltage above 58.4Vbattery protection will turn
on.Solution: Check whether voltage is too high or not, if it is, to change the settings
on power supply side 6) Low Voltage: When the battery discharges to 40V or less,
battery protection will turn on.Solution: Charge the battery for some time, the red
light will turn o.Excluding the four points above, if the faulty is still canot be
located, turm o battery and repair.
- The battery cannot be charged or discharged1) Cannot be chargedDisconnect
the power cables measure voltage on power side if the voltage is 56 5-57.6V
restanthe battery. connect the power cable and try again, if still not work turn o
batterv and contact distributor.2) Unable to discharge:Disconnect the oower
cables and measure voltage on battery side. if it is under 40v. please charge the
battery: if voltage is above 51.2V and still canot discharge, turm o battery and
contact . Emergency Situations
