Err #
Explanation
01
Battery with wrong ID. Charge not allowed.
The battery has a wrong ID resistor (not in the range
10Kohm ~ 60Kohm) and is not enabled to charge.
02
Battery failure: the battery does not accept any charge.
A generic battery failure: It means that the charger was
expecting the battery to charge, but it didn’t
Possible reasons are:
1) a real battery failure in the battery:
- electrical failure: something is disconnected internally,
maybe after a crash
- software failure: the battery has the safety settings locked
down and need to be reset (by BSMON)
2) a temporary safety protection activated
3) the battery is almost full and the charger attempt to
charge it without success: in this case discharge the battery
a bit more in order to start a new charging session.
The reason of the failure is usually described on the charger
display
03
Battery Voltage too low. Charge is not allowed.
The pack voltage is below 8V and is dangerous to attempt a
charge.
04
Timeout error in the charge session.
The battery does not terminated the charge in the expected
time. This error may occur charging pack with large
capacity. In this case simply remove the battery and install
again to reset the timer and start a new session until the
battery is full.
05
Premature charge termination. The charge process has
terminated unexpectedly.
This error means that the battery started charging but
suddenly stopped.
It may be a temporary inability of the charger to charge, or
the battery went in to a temporary protection state. Perhaps
it could be that some cell has a voltage too high, and during
the charge process this would cause the pack protection
safety to trip in order to avoid dangerous overvoltage
conditions.
When this error occurs, the charge session is reset every
minute, and the charge is re-attempted.
This error occur also when a battery too hot (> 45°C) or too
cold (usually < 0°C) is inserted on the charger: in this case
the session does not stop but the charger retry automatically
every 30 seconds until the battery allow charging.
