Outline
In order to improve the health of charging piles, a charging scheduling strategy for electric vehicles based on pile health status is proposed. The strategy begins with a comprehensive assessment model that evaluates charging pile health through electrical and safety performance indicators, using 6 core modules and 26 indicators as the evaluation framework. Secondly, considering the impact of charging load on pile health, a charging optimization model based on pile health status is established. Charging load is standardized by converting it into charging time, allowing operators to plan vehicle charging locations using both charging time and pile health as guiding factors. Finally, the NSGAII algorithm is employed to solve the model, with the charging pile health model used for evaluation. Parameters and charging data from 10 charging piles in a region of Jiangsu Province are selected for verification, and two different optimization scenarios are set up for comparison. The results show that, compared to the other two scenarios, the proposed strategy and algorithm increase the annual health of charging stations by 18.54%, improve the average annual health of charging piles by 1.85%, and reduce the maximum monthly health variance of charging stations to 0.001 5.
