The present disclosure relates to the technical field of charging guidance signal acquisition for new energy vehicles, and provides a charging guidance signal acquisition circuit, a new energy vehicle-mounted charging socket and a charging pile. The charging guidance signal acquisition circuit includes: a signal amplification and filtering circuit configured to receive a charging guidance signal, and amplify and filter the received charging guidance signal; and a voltage divider circuit, an input end of which is connected to an output end of the signal amplification and filtering circuit, and configured to adjust the charging guidance signal processed by the signal amplification and filtering circuit to a target value, which is a voltage that meets electrical requirements of a charging guidance signal input pin of a vehicle-mounted charging controller; the voltage divider circuit includes at least two adjustable resistors connected in series, and resistances values of the adjustable resistors are adjustable according to the electrical requirements of the charging guidance signal input pin. The embodiments of the present disclosure can overcome or alleviate the problem that it is difficult to charge the new energy vehicle normally due to the lack of uniformity charging guidance signal standards.
