The invention discloses a detection device for a direct current output loop of a charging pile and the charging pile. The detection device comprises a voltage difference detection module and a charging control module, and the voltage difference detection module and the charging control module are in communication connection. The voltage difference detection module is used for being connected with a to-be-detected circuit in a direct current output loop of the charging pile and collecting a sampling voltage value of the to-be-detected circuit; the charging control module is used for determining an equivalent internal resistance value of the to-be-detected loop according to the sampling voltage value acquired by the voltage difference detection module and a sampling current value of the direct current output loop of the charging pile; and the charging control module is also used for judging whether the to-be-detected loop has a fault according to the equivalent internal resistance value and interrupting the charging process of the charging pile under the condition that the to-be-detected loop is judged to have the fault. The technical problem that the fault state of the to-be-detected circuit in the direct-current output circuit cannot be rapidly detected is solved.
