An electric vehicle, a multifunctional car charger therefor and a control method thereof. The charger includes: a bidirectional AC/DC conversion circuit, a first and a second DC/DC conversion circuit, a sampling circuit and a control module. The sampling circuit samples a voltage and a current of a power grid, a voltage of the direct-current end of the bidirectional AC/DC conversion circuit, a voltage and a current of the power battery and a voltage and a current of the low-voltage battery respectively; and the control module is configured to control the bidirectional AC/DC conversion circuit, the first DC/DC conversion circuit and the second DC/DC conversion circuit according to the sampling result of the sampling circuit, to realize any one of a power battery charging function, a low-voltage battery charging function, a power battery alternating-current inversion function, a low-voltage battery alternating-current inversion function and a power battery low-voltage loaded output function.
