10.8.3 On-board battery charger General

The charger is optimised for gel valve regulated lead batteries. The charger is protected against dust and water jets (IP65).

The charger is connected to a normal earthed 230 V single-phase wall socket. The charging process is automatic.

Charging

Connect the charger’s mains plug (Fig. 11 A) to the mains supply. If a discharged battery is connected, the charger will start with the main charge (yellow LED (Fig. 11 B) and 28.8 V). When the battery is fully charged, maintenance charging starts (yellow and green LED (Fig. 11 B & C) and 27.6 V). This continues until the charger switches off. If a fully charged battery is connected to the charger or if the charger does not find a connected battery the maintenance charge is started (yellow and green LED 27.6 V). The charger starts with the main charge (yellow LED and 28.8 V) after a power failure if a discharged battery is connected.

The truck’s mains lead can be connected to the mains supply whenever the truck is not in use to ensure the batteries are always fully charged. Charging for at least 30 min. is gentle and consequently does not shorten the life of the battery. It is however necessary for the truck to be recharged once a week over night or for at least 10 hours.
