Abstract
A short-circuit current protecting method of a charging control system is cooperating with at least a control unit and a plurality of power outlet electrically connected to an electronic switch. The control unit controls the mode of the electronic switches with turn on or off. The short-circuit current protecting method includes the following steps. Step 1 is detecting at least a current signal value of an AC power. Step 2 is determining whether the current signal value is grater than a predetermine current threshold. Step 3 is enabling a short-circuit current analyzing module if the current signal value is grater than the predetermine current threshold. Step 4 is turning off at least one of the electronic switches if the short-circuit current is determined by the short-circuit current analyzing module.
