4.2 Troubleshooting
The BMS interrupts the charging or discharging process in the following cases:
−
A
s soon as the voltage of a cell reaches more than 3.9V - the BMS switches the charge on
again as
soon as the
cell voltage reaches 3.6V
.
−
A
s soon as the voltage of a cell reaches less than 2V - the BMS allows a current drain again
as
soon as the
voltage reaches 2.5V
.
−
Switch-off due to overload - please refer to the specifications of the individual batteries,
sometimes
high starting
currents of capacitors in inverters or other consumers must be taken
into account --- the
overload lock is cancelled
8
seconds after the load is switched off
.
−
The charge/discharge process is interrupted when the battery temperature reaches 65
°
C - the
error
is
automatically cleared when the temperature reaches 50
°
C
.
−
If the maximum permissible pulse discharge current is exceeded, it is possible that the BMS
will find
the "Short
circuit" error in a continuous loop between "Short circuit" and "Short circuit
aborted".
If t
his error message does not
end itself, the battery function can be restored by
disconnecting the
loads and simply charging (>13.8V)
.
−
If an error is not automatically cleared and the battery remains in error mode, please send an
error
message to
[email protected], if necessary with screenshots from the app or other
meaningful
image material
.
