Charging Behavior With Non Can-Capable Charger; Driving Behaviour; Balancing Function - probst VM-301-KJ-GREENLINE Operating Instructions Manual

with the battery system has been properly observed. The BMS automatically controls the
corresponding charger.
If the system was previously in drive mode, it automatically switches to charge mode as soon as
the charger plug is connected and the charger is active. The driving mode is no longer active.
The system does not leave the charging mode even after the charging process has been
successfully completed. The charger is controlled via the CAN interface. If a battery cell reaches
the maximum charging end voltage or the maximum SoC is reached, the charging process is
interrupted and the balancing function is activated. If the voltage of the battery cell drops again
by more than 50 mV, although the charging process was completed, the charging process is
reactivated.
The maximum end-of-charge voltage is set at the factory in such a way that sufficient
recuperation capacity is also possible at the beginning of the subsequent driving operation and
the ageing of the battery system is minimised. The value of the maximum charge end SoC can
be found in the parameter list.
The circuit-breaker is only opened in the event of a fault. The charge control is only done via the
CAN signal. The charge current in the charge mode is controlled based on the battery
temperature and the SoC and is calculated using a stored linear function.

6.2.2 Charging behavior with non CAN-capable charger

If no CAN-capable charger is used, the BMS automatically switches to charging mode if the BMS
detects a charging current for at least one minute.
The maximum end-of-charge voltage must be set by the customer on the charger. Probst GmbH
recommends to limit the maximum charge cut-off voltage to 95 % of the maximum system
voltage.
Overloading to over 100% must be prevented by the customer. This can lead to unsafe
▪
conditions and increased aging.
The balancing function is only active during longer periods of rest.
The circuit breaker is only opened in the event of a fault (e.g. excessive charging current).
Charging is controlled exclusively via the acoustic signal generator.

6.2.3 Driving behaviour

As soon as the ignition switch is activated, the battery system starts up and automatically goes
into DRIVE mode - if the charger is not connected.
The circuit-breaker is only opened in the event of a fault. The power control of the system in
driving mode is done via the CAN signals and acoustically via the signal generator. Based on the
states of charge, temperatures and voltages of the battery cells, the current performance of the
system is transmitted via the CAN interface.

6.2.4 Balancing function

The balancing function is only activated when the battery system is fully charged in charging
mode or if the battery system is inactive for more than one minute. During charging and
