Solution for Efficiently Charging of a Camper Van Battery

To make possible powering all appliances installed into a camper van room, an efficient power supply system must be designed. It should be able to collect energy from either the power grid or the solar panel system or other renewable energy, when the camper is parked into a camping spot. The energy is also needed when the camper is stopped into the wild. Moreover, the battery can be charged from the car alternator, while the camper van is moving from one place to another. This paper aims to provide necessary information about constructing a charging system for the battery which powers the electronics into the camper van room, focusing on comparing different approaches. It is demonstrated that using only three solar panels with a cumulative power of 250Wh, enough energy for powering all appliances of high necessity for a camper van is obtained.
