An Electric Vehicle Supply Equipment (100) includes a plurality of first power modules (112, 114, 116) and a control circuit (120). The first power modules (112, 114, 116) are electrically coupled in series at output and configured to provide a charging current (Ic) and a charging voltage (Vc) to charge an Electric Vehicle (200). The control circuit (120) is configured to output a first current control signal (CS_I) to control one of the first power modules to be operated in a constant current mode and output first voltage control signals (CS_V) to control the other first power modules to be operated in a constant voltage mode respectively. The control circuit (120) controls the charging current (Ic) via the first power module operated in the constant current mode, and controls the first power modules operated in the constant voltage mode have the output voltages corresponding to their first voltage control signals respectively.
