Design and Research of a DC Charging Station Measurement and Monitoring System for Electric Vehicles Based on DC Measurement Chips

Abstract

This paper designs a DC charging station measurement and monitoring system for electric vehicles based on DC metering chips, integrating DC meters and billing control units, and integrating DC meters, splitters, and billing control units. Implementing an integrated design approach, the system comprises a Metering Module and a Billing Control Module. The Metering Module is tasked with gathering and quantifying the charger's energy consumption. It transmits the recorded voltage, current, and energy data to the Billing Control Module. The Billing Control Module, in turn, engages with users and performs various functions including fee payment, charging mode selection, and control of the charging device.
