Technical description

The battery charger monitors the voltage and thereby the state of charge (SoC) of the house battery. The battery charger regulates the output current according to the requirements of the house battery and the amount of energy supplied. When charging a house battery, the battery charger consumes 13 mA.

Functions

The battery charger provides the following functions:

• Charging with up to 40 Ah
• Efficiency of up to 92%
• 5-stage charging
• Selectable charging curve for AGM, Gel, Flooded, and Lithium (LiFePO4) batteries
• Auxiliary connection for 12 V devices
• A split-charge relay for separating the starting and house battery
• Compatible with Euro 6 vehicles with smart alternator
• Cooling fan speed regulation
• Overheating protection
• Fuses for circuit protection
• Alternator overload protection
• Overvoltage protection for solar modules
• Power supply when no house batteries are connected
• Automatic emergency switch that switches back to the original charging system in the event of a fault

While driving the battery charger gradually reduces the output current if the alternator is overloaded and the input voltage of the alternator and/or the starting battery falls below 12.8 V.

The battery charger’s cooling fan is only activated when the battery charger internally reaches a certain temperature. The speed of the cooling fan is controlled electronically depending on the internal temperature of the battery charger. If the internal temperature of the battery charger is too high, the battery charger automatically reduces the output current and switches itself off at a certain temperature. The battery charger reactivates itself as soon as the internal temperature of the battery chargers returns to an acceptable working level.

Charging from the alternator

• After starting the engine the ignition+ or D+ signal connected to the battery charger input (Fig. 8 on Fig. 9) is active. If the input voltage exceeds 13.3 V, the battery charger starts charging the house battery.
• During the charging process the voltage of the starting battery is constantly monitored in order to quickly register supply problems or an overload of the alternator to reduce the output current soon or to stop the charging process completely.
• The output current is limited if the battery charger detects an active ignition+ or D+ signal and a starting battery voltage below 12.8 V.
• The battery charger switches off completely when it detects a voltage of 12.5 V on the starting battery or when the ignition+ or D+signal is no longer detected and the vehicle engine is switched off.
• When selecting the charging curve of the smart alternator for Euro 6 vehicles, the activation threshold of the battery charger is > 11.4 V after a few minutes and the deactivation threshold is < 11 V. The output current is limited if the battery charger detects an active ignition+ or D+ signal and a starting battery voltage below 11.6 V.

Charging from the solar panel

If the battery charger is connected to a solar panel and the ignition+ or D + signal is not active, the charging process starts via the integrated solar controller when the solar panel generates a voltage of more than 16 V. The battery charger terminates the charging process via the solar regulator when the voltage of the solar panel is lower than the voltage of the house battery.

Priority levels

The power source is selected according to the following power priority:

1. Alternator
2. 230 V power supply (GOLD25-M, GOLD30-M and GOLD40-M only)
3. Solar panel

Connecting 12 V devices

The battery charger is equipped with an auxiliary connection socket (Fig. 8 / Fig. 9). The connection is used to connect the split-charge relay or the original control unit where 12 V devices such as a refrigerator, lighting, a pump, etc. are connected (see Installation).

The devices connected to the auxiliary connection are supplied via the house battery when the ignition+ or D+ signal is not active. When the ignition+ or D+ signal is active, a relay ensures that the devices connected to the auxiliary connection are supplied with power from the alternator.

LED indicator

• The battery charger is equipped with LED indicators that show the source of the incoming charge.
• The LED indicators also show the battery’s current charging phase by flashing a specific number of times (see Configuring the battery charger).
