The invention discloses a direct-current charging safety monitoring device for an electric automobile. The direct-current charging safety monitoring device comprises a signal detection circuit and a microprocessor, wherein the signal detection circuit is connected with the microprocessor. A handshake analog signal is skillfully converted into a digital signal through a photoelectric coupled isolate circuit, so that the difficulty in data processing is lowered; isolation between the detection circuit and a single-chip microcomputer is realized through a signal isolation circuit; compared with charging handshake by means of A/D (Analog/Digital) detection, the direct-current charging safety monitoring device has the advantage that the circuit cost is relatively low.
