A distributed power-sharing electric vehicle (EV) charging. The system comprises multiple chargers connected via a network. Each charger includes a power module configured to store direct current (DC) power, an output port for supplying power to an electric vehicle, and a sharing port for exchanging power with at least one neighboring charger. First and second switches are positioned between the power module and the output port, and between the power module and the sharing port. A control unit is configured to control the operation of the power module and the switches in response to an EV charging request. When the maximum charging power required by the EV exceeds the rated output power of a single charger, the system delivers power from both the power module and the neighboring charger in an idle state.
