Battery Sensor
An Intelligent Battery Sensor (IBS) has been connected to the
battery terminal. It measures and monitors the actual current,
actual voltage and temperature of the batteries in a highly precise
manner. Normally, the battery sensors are calibrated automati-
cally. To calibrate the battery sensor manually, please follow the
instructions in Chapter 7.3 Battery Management.
Intelligent Battery Sensor (IBS)
If there is a loss of power in the battery sensor (voltage
absent), you must recalibrate.
The battery sensor is protected by a 10 A .
The charge state of the battery, age or remaining time until
discharge are all shown on the TFT display of the control panel.
Charging is carried out gently in accordance with the steady-state
principle by an "intelligent" charger.
• Always charge the ancillary battery for at least 24 hours before
each journey, directly after each journey and before you take the
van temporarily out of service.
- Before each journey, please check that the battery is
charged (
see p. 78
). If necessary, connect it to the
mains to start charging the battery.
- The battery is only charged if it has a minimum voltage of 8 V.
- Use every opportunity during your journey to charge
the battery.
• If the vehicle is not in use for a longer period of time, the battery
should be disconnected after it has been optimally charged by
switching the battery circuit breaker on.
It is possible to determine the remaining operating time of the
battery based on the current consumption. The IBS ensures that
the battery will be changed in good time and assists in providing
active energy management so that the performance requirements
of the different electrical devices can be coordinated with the
charging of the battery.
