1. A distributed power sharing type electric vehicle charging system comprising: a plurality of chargers connected through a network,
wherein each of the plurality of chargers includes:
a power module storing a DC power;
an output port supplying a power output from the power module to an electric vehicle;
a sharing port interconnected to a sharing port of at least one neighboring charger of the plurality of chargers, and receiving power shared by the at least one neighboring charger or delivering power of the power module to the at least one neighboring charger;
first and second switches installed between the power module and the output port and between the power module and the sharing port, respectively; and
a control unit controlling operations of the power module and the first and second switches according to an electric vehicle charging request, and, when maximum charging power of the electric vehicle is greater than rated output power of the charger, delivering both the power shared by the at least one neighboring charger in a paired state with the at least one neighboring charger in a current idle state, and the power output by the power module to the output port to rapidly charge the electric vehicle,
wherein, each of the plurality of chargers and the respective sharing port adjacent to each other in terms of a distance are connected to each other by a cable, and
wherein the control unit determines the maximum connection number of the at least one neighboring charger by using a ratio acquired by dividing the maximum charging power by the rated output power.
