Remote intelligent metering quality monitoring system for electric vehicle charging equipment

Abstract

The invention provides a remote intelligent metering quality monitoring system for electric vehicle charging equipment, and belongs to the technical field of electric vehicle charging pile metering quality monitoring. The system comprises charging equipment remote intelligent metering quality monitoring equipment and a cloud platform, the charging equipment remote intelligent metering quality monitoring equipment comprises a sampling module, a sampling CPU and a DTU communication module; the sampling module collects current and voltage in the charging process of charging equipment and transmits the current and voltage to the sampling CPU, the sampling CPU receives the collected current and voltage, carries out electric energy integration on the current and voltage to obtain an electric energy value, and transmits the electric energy value to the cloud platform through the DTU communication module, and the cloud platform compares the electric energy value with the electric energy indicating value fed back by the charging equipment to obtain an error value, and measurement quality monitoring result judgment is performed on the charging equipment according to the error value. According to the invention, alternating-current and direct-current integrated monitoring is adopted, the monitoring function of a non-vehicle-mounted charger and an alternating-current charging pile is also realized, and the requirement on accuracy in national verification regulations and detection standards can be met.

Description

technical field [0001] The invention belongs to the technical field of measurement quality monitoring of electric vehicle charging piles, and in particular relates to a remote intelligent measurement quality monitoring system for electric vehicle charging equipment. Background technique [0002] With the in-depth implementation of the national new energy electric vehicle strategic policy, electric vehicle charging facilities have grown rapidly, and the operation mode of the electric vehicle charging pile industry is mostly based on the Internet, with a unified operating platform for daily charging operations. Under such a market background, the traditional measurement quality supervision method is difficult to meet the real-time and efficient requirements of market supervision. [0003] Therefore, a new solution needs to be proposed to solve this problem. Contents of the invention [0004] The present invention mainly solves the technical problems existing in the above-me...
