The invention relates to a charging pile detection circuit, a charging system and a charging pile detection method. According to the charging pile detection circuit, a switch assembly is connected with a first relay and a second relay; the adhesion detection assembly is connected with the switch assembly; the control assembly is connected with the switch assembly and the adhesion detection assembly, and is used for controlling the conduction state of the switch assembly, receiving the adhesion detection signal output by the adhesion detection assembly, and determining the adhesion state of the target relay according to the adhesion detection signal. When the switch assembly is in a first conduction state, the adhesion detection assembly receives a first power supply signal when the second relay is adhered, and outputs a first detection signal according to the first power supply signal; when the switch assembly is in the second conduction state, the adhesion detection assembly receives a second power supply signal when the first relay adheres, and outputs a second detection signal according to the second power supply signal. The charging pile detection circuit can prevent the charging pile from being burnt.
