The invention discloses a method and device for analyzing the shared charging demand of electric vehicles. Firstly, the signal characteristics of the charging electric vehicle are extracted, and secondly, according to the characteristics, a feedforward neural network is used to identify and classify the electric vehicles, and then a charging habit model is established according to the daily charging demand histogram. Finally, the built model is improved by estimating the kernel density of daily charging demand, and the analysis of shared charging demand for electric vehicles is completed. The method proposed by the present invention is accurate and efficient, has strong versatility and practicability, and is of great significance to the orderly shared charging of electric vehicles in emerging residential quarters in the future.
Description
technical field [0001] The invention belongs to the technical field of electric vehicle charging, and in particular relates to an electric vehicle shared charging demand analysis method, and also relates to an electric vehicle shared charging demand analysis device. Background technique [0002] Electric vehicles are an important part of the current new energy industry and an effective tool to alleviate energy crises and environmental problems. At present, important progress has been made in the construction of the standard system of electric vehicle charging and swapping facilities, key technology research, key equipment development and demonstration project construction. But at the same time, the current commonly used electric vehicle charging system cannot meet the personalized charging needs of users. [0003] Therefore, through the continuous innovation and optimization of electric vehicle charging technology and the adoption of scientific and reasonable control strate...
