摘要

As a direct way to obtain energy for hydrogen fuel cell vehicles, the hydrogen filling has been of great concern for its filling rate, quality and safety. However, there is a lack of indicators to scientifically evaluate the comprehensive performance of different filling strategies. To solve the above problem, a numerical model of hydrogen storage tank (HST) filling with fluid–solid coupling on the inner wall surface is established, and a comprehensive evaluation indicator is determined by using the analytic hierarchy process and entropy method in this study. The results show that the surface temperature of the outer wall of the HST and the maximum temperature difference between the hydrogen zone and the inner wall surface are the key indicators for evaluating the safety of the filling process. Moreover, the comprehensive evaluation indicator has five sub-indicators, with filling time having the greatest influence (59.06%) and state of charge having the least (0.66%). More importantly, the identified comprehensive evaluation indicator can be carefully and accurately evaluated according to user preferences while ensuring a certain degree of objective evaluation. These findings provide new ideas and important references for the evaluation study of the HST filling process.
