The invention discloses an alternating current charging safety monitoring device for an electric vehicle. The device comprises a first voltage comparing circuit, a second voltage comparing circuit, a PWM detection circuit and a microprocessor, wherein the first voltage comparing circuit, the second voltage comparing circuit and the PWM detection circuit are all connected with the microprocessor. A handshake simulating signal is ingeniously converted into a digital signal through the comparing circuits and an isolating circuit, so that data processing difficulty is reduced; isolation between the detection circuit and a single-chip microcomputer is achieved through the signal isolating circuit; compared with the shake-to-charge method conducted by means of A/D detection, circuit cost is lower.
