The invention discloses a charging protection circuit of a charging pile. The charging protection circuit comprises a rectification circuit, a filter circuit, a voltage stabilizing circuit, a load charging circuit, an overcharge protection circuit and a short circuit protection circuit, wherein an input end of the rectification circuit is connected with the mains supply, an output end of the rectification circuit is connected with an input end of the filter circuit, an output end of the filter circuit is connected with an input end of the voltage stabilizing circuit, wherein an output end of the voltage stabilizing circuit is connected with a charging end of the load charging circuit, the short-circuit protection circuit is used for disconnecting the power supply and the charging circuit when the charging load circuit is short-circuited, and the overcharge protection circuit is used for disconnecting the power supply and the charging circuit after the charging load is charged. The charging protection circuit is advantaged in that the charging pile charging protection circuit can automatically disconnect the charging circuit after charging of the load is completed, and thereby overcharging is prevented, and when an external charging load is short-circuited, the charging circuit can be automatically disconnected to realize self-protection.
