Theory-and-practice combined state assessment system of new energy vehicle

For the pilot phase of fuel cell vehicles is concerned, it is necessary to understand real-time vehicle running state, so as to effectively avoid vehicle breakdowns caused by the security implications. Based on the study of the existed state assessment system of fuel cell vehicle, the author has used fuzzy logic inference system to improve its spare parts evaluation system in this article. By combining the theoretical value of each parameter with the measured value in the membership function and by the introduction of the concept of weights, this makes the fuel cell vehicle state assessment system more reasonable and accurate.
