Functions

The charger is equipped with a microprocessor (MCU - Micro Computer Unit) and features fully automatic charging-, diagnostic-, emergency- and maintenance functions. After selecting the battery type connected (12 V or 24 V) the battery charger will recognise the battery capacity and the battery condition and calculate the required charging parameters (charging voltage, charging current). This allows for efficient and safe charging. If the wrong battery voltage is set or the battery is defective, it will not charge and the "Error" LED (18) will light up (also see "Troubleshooting").

The "trickle charge" function allows the charger to be permanently connected. A full charge will be maintained.

The 'Power supply' function allows the charger to provide a bridging power supply. While changing the batteries, the charger provides the vehicle with electricity and no data is lost.

The 'Automatic temperature adjustment' function measures the ambient temperature and adjusts the charging phase according to the ambient temperature.

CHARGING PHASES

The concept of the charging process is explained based on a 12 V battery.

Diagnosis

Diagnostic function which automatically checks the battery status and recognises the voltage.

Voltage Function

0 V bis 1.5 V “Error” LED (18) lit. Battery defective.

1.5 V bis 12 V Charging starts.

12 V bis 13 V Maintenance charging starts.

14.6 V Battery fully charged. “Full” LED (16) lit.

>15 V “Error” LED (18) lit.

Step 1: Condition check

The charger checks the battery condition and calculates the required charging parameters.

Step 2: Desulphation (rescue)

The charger can rescue most drained batteries with voltages up to a minimum of 1.5 ± 0.5V .
- The safety switch does not allow the charger to start charging if the voltage is below 1.5 ± 0.5V .
- At a voltage range of 1.5 ± 0.5V to 10.5 ± 0.5V the charger will initiate pulse charging.
- If the voltage rises above 10.5 ± 0.5V , the charger will switch to the previously selected regular charging mode, which will charge faster and more safely.

Step 3: Precharging

The battery is gently charged with a low charging current to return the battery to a chargeable state.

Step 4: Soft start

The battery is gently charged with a low charging current.

Step 5: Base charge with a constant current

The battery is quickly and safely charged with a consistent current.

Step 6: Base charge with a constant voltage

The battery is charged at a constant charge end voltage until it is fully charged.

Step 7: Analysis

Once the battery is fully charged, the charging process will stop.

Step 8: Equalisation charge

If the battery is fully charged and drops to 12.8V within 2 minutes, another charging process will begin automatically.

Step 9: Maintenance charging

The charger monitors the battery capacity. Once the battery falls below 12.8V , the charger will emit a charging pulse. This maintains the battery's highest possible charging level.

SAFETY FUNCTIONS

The charger features the following safety features to prevent damage to the charger and the battery or the vehicle:

short circuit (defective battery),

incorrect connection (connected with reversed polarity),

parking
overheating
excess current
