Development And Verification Of Electric Vehicle User Experience Evaluation System

As the process of sustainable development continues,electric vehicles as new energy vehicles are being developed and competition in the domestic and international electric vehicle market is becoming increasingly fierce.In addition to technological innovation,more and more companies are beginning to focus on the user experience.In recent years,many researchers have studied the willingness to use electric vehicles,but fewer scholars have focused on the establishment of a user experience evaluation system for electric vehicles.There are now also evaluation systems with relatively single indicators and relatively traditional methods.Therefore,this study aims to explore the establishment of a multi-dimensional and multi-indicator EV user experience evaluation system,so as to further explore user needs and broaden the EV market.Study 1 combined with literature,established a user portrait of electric vehicles through questionnaire method and text mining,further explored user needs and provided a basis for the construction of electric vehicle user experience evaluation dimensions.Study 2 constructed a user experience evaluation system for electric vehicles through the interview method and combined with the results of Study 1.In Study 3,an empirical study was conducted to analyse the differences in user experience between different brands of electric vehicles and to explore the mediating role of usability and central control interaction between price and willingness to use.The main findings of this study are as follows.(1)This study divides functional,interactive,and emotional types of user groups through text mining and text clustering,and found that different user groups have different demand for electric vehicles.(2)This study constructs a user experience evaluation system for electric vehicles,which includes three dimensions: functional experience,interactive experience and emotional experience.The functional experience includes two secondary indicators,namely usability and range;the interactive experience includes two secondary indicators,namely intelligent interaction and central control interaction;and the emotional experience includes two secondary indicators,namely attractiveness and aesthetics.(3)The overall evaluation of electric vehicles is good,with significant differences between different groups in each dimension.Different brands differed significantly in all dimensions except for the aesthetics dimension.Usability and central control interaction play a fully mediating role between price and intention to use,with a chain mediation model.(4)This study has established a more comprehensive evaluation system taking into account vehicle characteristics and user psychology,which is an important reference for both consumers and car manufacturers.
