Technical description
- The battery charger can charge batteries that are used on board vehicles to generate power or supply the batteries with a retention voltage so that they do not discharge.
- The battery charger is automatically charging the batteries and maintains them with float voltage after the charging has finished.
- The battery charger can be connected to the batteries for a longer time without damaging them.
- The battery charger can be supplied for charging from an external AC power source or a DC power source from the alternator inside the vehicle. When charging from an AC source the battery charger can charge 2 batteries independently of each other.
- When charging from a DC power source, the charging voltage is independent of alternator voltage variations due to a built-in buck-boost regulator.
- The vehicle start can be supported with the built-in buck-boost function during the start cycle or the possibility to charge the starting battery for a limited time via the house battery.
- The built-in buck-boost function allows the house battery to be charged while driving.
The charging process can be controlled via:
- A remote control
- A monitoring and controlling device
- The vehicle CI bus
- An intelligent battery sensor (IBS)
The battery charger can operate in 3 different modes:
Mode | Description |
---|---|
Slave mode | The battery charger is not connected to an IBS. The charging |
of the battery is controlled by the CI bus of the vehicle, a remote control,
or a monitoring and controlling device. The charging voltage and currents are
set by the device controlling the battery charger. If the battery charger is
connected to an AC source and 2 batteries, a maximum current of 25 A per
battery can be set. The starting battery is automatically prioritized by the
battery charger for charging when 2 batteries are connected. If only 1 battery
is connected to the battery charger, the connected battery is supplied with a
maximum current of 25 A. If the battery charger is connected to a DC source,
the maximum current is 30 A.
Master mode| The charging of the house battery depends on the IBS signals. The
charging of the other battery is controlled by the charger itself or with the
vehicle’s CI bus, remote control, or monitoring and controlling device. If the
battery charger is connected to an AC source, the starting battery is supplied
with a maximum of 10 A charging current, and the house battery is supplied
with a maximum of 25 A. If both batteries are charged, the total maximum
charge current is 25 A. The starting battery is automatically prioritized by
the battery charger for charging when 2 batteries are connected. If the
battery charger is controlled by the vehicle’s CI bus and is connected to an
AC source, the starting battery, and the house battery, the maximum charge
current supplied is 25 A. When one battery charges the other battery, the
maximum charge current is 30 A.
Normal mode| The battery charger is neither connected to an IBS, the CI
bus of the vehicle, a remote control, or a monitoring and controlling device.
If the battery charger is connected to an AC source, the starting battery is
supplied with a maximum of 10 A charging current, and the house battery is
supplied with a maximum of 25 A. If both batteries are charged, the total
maximum charge current is 25 A. The starting battery is automatically
prioritized by the battery charger for charging when 2 batteries are
connected. When one battery charges the other battery, the maximum charge
current is 30 A.
- If the communication between the remote control or a monitoring and controlling device and the battery chargers is interrupted, the battery charger switches to float charge.
- After 8 h float charging, the battery charger automatically switches to the master or normal mode. If the battery charger communication is activated again, the battery charger switches to slave mode after 10 seconds.
- The battery charger uses the last configuration saved for the battery.
- If the batteries are fully charged, the 25 A supplied by the battery charger can be used to supply power to the vehicle interior.
- The battery charger is equipped with an AC interlock socket. When the battery charger is connected to an AC source, an internal relay of the battery charger short-circuits the AC interlock socket, which connects the battery charger to the vehicle’s starting circuit to prevent the vehicle from starting.
- The battery charger is equipped with a jump starter button that allows charging of the starting battery using the house battery.
The battery charger has the following protective systems:
- Overvoltage protection
- Overheating protection
- Overload protection
- Short circuit protection
- Output polarity protection

Battery charging function
Lead acid, AGM, and GEL batteries Fig. 4
- Analysis phase
- The battery is deeply discharged (<10 %). The battery charge is analyzed with increasing charging current.
- The corresponding LED indicator of the battery that is charged flashes fast yellow.
- I phase (Constant current phase)
- At the beginning of the charging process, the empty battery is constantly charged with the maximum charging current (100 %). The charging current decreases when the battery has reached a state of charge of 75 %.
- Batteries with low voltage are charged with reduced current until the battery voltage exceeds 9 V. The duration of the I phase depends on the state of the battery, the connected load, and the state of charge.
- For safety reasons, the I phase is terminated after a maximum of 26 hours (in case of battery cell defects or similar).
- The corresponding LED blinks yellow.
- U0 phase (Constant voltage phase)
- The U0 phase starts when the battery reaches 15 V. The charging current is reduced. During the U0 phase, the battery voltage is kept constant at a high level.
- The duration of the U1 phase depends on the battery type and the depth of discharge.
- The corresponding LED flashes slow yellow.
- U1 phase (Trickle charging)
- The U1 phase serves to maintain the battery capacity (100 %). The U1 phase runs at lowered charging voltage and variable current. If DC loads are connected, they are powered by the device. Only if the power required exceeds the capacity of the battery, surplus power is provided by the battery. The battery is then discharged until the device re-enters the I phase and charges the battery.
- The corresponding LED flashes slow green.
- U phase (Float)
- In long-term mains operation, the U phase prevents the further discharge of the battery (e.g., during long breaks in use, seasonal operation, or during winter storage), minimizes battery gassing, and prevents plate corrosion.
- The corresponding LED is lit green.
- Reconditioning
- Every 12 days, the charger switches back to the U0 phase for a short time (max. 85 min) to recondition the battery. This prevents any fatigue phenomena such as sulfation or electrolyte stratification.
- The corresponding LED flashes fast green.
LiFePo4 batteries Fig. 5
- I phase (Constant current phase)
- At the beginning of the charging process, the battery is charged with a constant current (100 % charge current) until the battery voltage reaches 14 V.
- The charging current decreases when the battery has reached this charging level. For safety reasons, the I phase is terminated after a maximum of 18 h (in case of battery cell defects or similar)
- The corresponding LED indicator of the battery that is charged flashes yellow.
- U0 phase (Trickle charging)
- Now the trickle charging process (U0 phase) begins, where the duration depends on the battery. The voltage remains constant (U0). Then the main charging phase begins when the battery is fully charged.
- Once the battery is completely charged, or the charging current is below 6 % of the rated charging current for 15 min, the U0 phase has finished.
- The corresponding LED flashes yellow.
- U phase (Float)
- After the U0 phase, the battery charger switches to the conservation charging function (U phase). If DC loads are connected, they are powered by the device.
- Only if the power required exceeds the capacity of the device, this surplus power is provided by the battery. The corresponding LED is lit green.
- U phase (Float)
- The battery is then discharged until the device re-enters the I phase and charges the battery.
- The corresponding LED is lit green.
- I phase (Constant current phase)
- See 1 : I phase (Constant current phase).
- U0 phase (Discharging)
- See 2: U0 phase (Trickle charging).
- U phase (Float)
- See 3 : U phase (Float).
- Reconditioning
- Every 12 days, the charger switches back to the U phase for a short time (max. 85 min) to recondition the battery (see 3: U phase (Float)).
- This prevents any fatigue phenomena such as electrolyte stratification.
