The invention provides a direct-current charging control guide circuit and a control guide method thereof. The circuit comprises a charging pile charging control circuit, wherein the charging pile charging control circuit comprises a power supply, a first resistor, a second resistor, a first switch and a third resistor; a charging plug which is connected with the charging pile charging circuit and comprises a protection ground wire contact pin, a connection validity detection contact pin and a connection protection contact pin; a charging socket comprising a first slot corresponding to a protection ground wire pin of the charging plug, a second slot corresponding to an effectiveness detection pin of the charging plug, and a third slot corresponding to a connection protection contact pin; and a fourth resistor, a second switch and a fifth resistor connected in series. According to the invention, redundant signal pins are cancelled, the influence of the vehicle auxiliary power supply on the control guide circuit is reduced, the state of the protective ground wire pin is monitored in real time, and the unification of the arrangement of the direct current charging control guide circuit for vehicles with different auxiliary power supply voltages is facilitated. Meanwhile, the circuit is simple to adapt to an existing national standard circuit, and is better in popularization performance.
