The embodiment of the invention provides a high-voltage system of an electric automobile, the electric automobile and a control method of the high-voltage system. The high-voltage system of the electric automobile comprises a power battery, a power distribution box, an alternating current control unit, high-voltage electric equipment, a first relay and a second relay. The power battery is used for supplying power to the distribution box; the power distribution box is connected with the power battery and the alternating current control unit. Two ends of the first relay are respectively connected with the positive electrode of the power battery and the positive electrode of the power distribution box, and the first relay is used for disconnecting or connecting the power battery and the power distribution box; the two ends of the second relay are connected with the negative electrode of the power battery and the negative electrode of the power distribution box respectively, and the second relay is used for disconnecting or connecting the power battery and the power distribution box. By means of the high-voltage system of the electric automobile, the safety of the electric automobile is effectively improved, and meanwhile energy consumption is effectively reduced.
