Abstract
A method of controlling power supply of a caravan including a photovoltaic plate includes: receiving a first power parameter of an input interface element; determining whether there is a mains supply to be input into the input interface element according to the first power parameter; turning on a first switch to make the input interface element be electrically connected to the output interface element if the mains supply is input into the input interface element; receiving a power parameter of a battery pack if the mains supply is not input into the input interface element; determining whether a remaining power of the battery pack exceeds a power threshold according to the power parameter of the battery pack; and making the battery pack be electrically connected to an output interface element if the remaining power of the battery pack exceeds the power threshold.
