Title:
CHARGING GUIDANCE SIGNAL ACQUISITION CIRCUIT, NEW ENERGY VEHICLE-MOUNTED CHARGING BASE, AND CHARGING PILE
Document Type and Number:
WIPO Patent Application WO/2023/051578
Kind Code:
A1
Abstract:
The present invention relates to the technical field of charging guidance signal acquisition of new energy vehicles, and a charging guidance signal acquisition circuit, a new energy vehicle-mounted charging base, and a charging pile are provided. The charging guidance signal acquisition circuit comprises: a signal amplifying and filtering circuit, used to receive a charging guidance signal, and amplify and filter the received charging guidance signal; and a voltage divider circuit, having an input terminal connected to an output terminal of the signal amplifying and filtering circuit, and used to adjust a charging guidance signal processed by the signal amplifying and filtering circuit to a target value, the target value being a voltage value that meets an electrical requirement of a charging guidance signal input pin of a vehicle-mounted charging controller. The voltage divider circuit comprises at least two adjustable resistors connected in series, resistance values of the adjustable resistors being adjustable according to the electrical requirement of the charging guidance signal input pin. Embodiments of the present invention can overcome or alleviate the problem of ordinary charging of a new energy vehicle being difficult because of non-uniform charging guidance signal standards.
