The invention relates to the technical field of electric vehicle charging, and discloses an electric vehicle charger which comprises a rectifying unit, a voltage stabilizing unit, a main control unit, a first switch unit, a first PWM driving unit, a boosting unit, a second switch unit, a second PWM driving unit, a Bluetooth unit, an RAM storage unit and a sampling unit. In actual use, the main control unit controls the turn-on and turn-off frequencies of the first switch unit through the first PWM driving unit, so that the output voltage and the output current of the first switch unit are in a first interval and a second interval respectively, and then an electric vehicle with the voltage specification in the first interval and the current specification in the second interval can be charged. The main control unit controls the on-off frequency of the second switch unit through the second PWM driving unit, so that the output voltage and the output current of the second switch unit are in a third interval and a fourth interval respectively, and then the electric vehicle with the voltage specification in the third interval and the current specification in the fourth interval can be charged.
