An electric vehicle supply equipment includes multiple first power modules and a control circuit. The first power modules are electrically coupled in series at output and configured to provide a charging current and a charging voltage to charge an electric vehicle. The control circuit is configured to control one of the first power modules to be operated in a constant current mode to output the charging current, and configured to control the rest of first power modules to be operated in a constant voltage mode respectively to have at least one output voltage for generation of the charging voltage.
