Abstract

The invention discloses a DC charging pile voltage error compensation method, system and device and a readable storage medium, and the method comprises the steps: taking an error as a dependent variable, and taking temperature and humidity as independent variables to carry out voltage standard meter measurement, and obtaining an error value under the condition that the temperature and humidity are taken as dependent variables; establishing a variation function model by taking the temperature, the humidity and the obtained error value as sample values; according to the humidity and the temperature collected in real time, Kriging interpolation is carried out to obtain a calculation error, a voltage measurement value of the direct current charging pile to be compensated is corrected according to the calculation error to obtain a corrected voltage value, and error compensation under any temperature and humidity conditions on site is realized by adopting Kriging interpolation. The accuracy of voltage measurement and electric energy metering is improved, and a theoretical basis is provided for large-scale remote online monitoring of the direct-current charging pile.

Description

technical field [0001] The invention relates to the accuracy of electric energy measurement of a DC charging pile on-site detection device under on-site working conditions, in particular to a DC charging pile voltage error compensation method, system, equipment and readable storage medium. Background technique [0002] As an important infrastructure for the rapid development of electric vehicles, the accuracy of electric energy metering of charging piles is a hot issue that electric vehicle consumers and society pay attention to. However, the traditional charging pile measurement accuracy detection is carried out by carrying the detection device and the load to the site. The detection device is cumbersome and the process is cumbersome, and the temperature, humidity, and the unsteady waves output by the charging pile, such as ripple and distortion, will affect the field conditions. The results of on-site inspections have a greater impact. Therefore, it is of great significan...
