6 Troubleshooting
When the battery fails to work normally due to abnormal conditions,
troubleshooting is required. Common battery failures and solutions are as
follows:
Fault 1: Abnormal communication with the compatible inverter
Case A. RS485 Communication Exception
Case B. CAN Communication Exception
Solution: Set the address of each PB2 according to Section 3.3.3 DIP Switch, use
the appropriate communication cable, select the correct
communication interface, and confirm that the inverter uses the same
baud rate as the battery. Set relevant parameters of inverter. Refer to
the inverter user manual for its setting method.
Fault 2: Unable to turn on
Case C. Press the WAKE UP button for 2-3 seconds, and the display panel will
not light up.
Solution: The battery capacity may be too low. Use the charger or inverter to
supply more than 51V voltage to the battery. If the battery is turned on
automatically, it can be charged, and the charging current is set to
0.05C. Use BMS monitor to check the battery status.
Fault 3: Unable to charge
Case D. After the battery is turned on, the display panel will display normally.
But the battery cannot be charged.
Solution 1: When the battery is fully charged, SOC will display 100%. Do not
recharge
the battery.
Solution 2: The PB2 voltage is lower than 56.8V and SOC is less than 100%, but
the battery is in charging state. No need to deal with it. The battery is
charging and will be fully charged after a period of time.
Solution 3: The fuse is blown. Turn off the PB2 and contact the dealer for
assistance.
Case E. After the battery is turn on, the status indicator is always red and the
battery cannot be charged.
Solution 1: If the error code is E3 or E5, move the battery to an environment with
a temperature range of 0 ℃~50 ℃.
