Abstract

The invention relates to a metering and verification device for a charging pile. The metering and verification device for a charging pile includes a main body of the charging pile and a controller. The main body of the charging pile is connected to the controller. The controller includes an MCU, a storage module, a communication module, and a power meter Module, analog-to-digital converter, current measurement module and voltage measurement module, in which the MCU is bidirectionally connected to the storage module and the communication module; the current measurement module and the voltage measurement module are both connected to the main body of the charging pile to detect the charging current and charging voltage of the main body of the charging pile, and the current The signal output terminals of the measurement module and the voltage measurement module are connected to the analog signal input terminal of the analog-to-digital converter. The digital signal output terminal of the analog-to-digital converter is divided into two channels, one is input to the power measurement unit, and the other is input to the MCU. The signal output end of the metering unit is connected to the signal input end of the MCU; the invention can verify the power metering of the charging pile, and connect to a remote server to assist in calculation, so as to obtain accurate calculation data.
