VW T5 Kombi Conversion

Charging System

12v Charging Supply

The obvious plan of attack is for a VSR (Voltage Sensing Relay). The VSR is connected across the main engine battery and if the engine battery is above a threshold voltage (pre determined and set inside the VSR unit), the relay is energised and allows a positive voltage to pass from the engine battery, through the contacts of this VSR, to the Leisure Battery and thus charge the leisure battery.

The requirement is for Leisure Battery to be charged up either via the van battery or 240v battery charger.

Electrical equipment to be supplied by the van will be:

• Laptop (Not always, but requirement is there);
• LED lighting
• Coolbox
• Battery Drills
• Mobile Phone Chargers

Not much really.
