Abstract

This study employs data-scraping and analysis of 11,525 Plug-in Electric Vehicle (PEV) user reviews from 2018 to 2024, focusing on users’ battery performance satisfaction with electric range, battery degradation, and charging experience. Using SnowNLP, Multinomial Naive Bayes, and Bidirectional Encoder Representations from Transformers (BERT), along with an explainable machine learning algorithm, the findings identify location and vehicle price as critical factors influencing PEV perceptions. Battery Electric Vehicles (BEVs) receive consistently more positive feedback than Plug-in Hybrid Electric Vehicles (PHEVs) across the Chinese Mainland, though satisfaction for both declines with vehicle age. PEVs with an all-electric range of under 100 km get predominantly negative reviews after over four years of use. To boost PEV adoption and satisfaction, targeted incentives for PHEVs with 150–200 km and BEVs with 550–600 km range in lower-tier cities are recommended. These findings offer valuable insights for manufacturers and policymakers promoting PEV market growth in China.

从在线评论评估中国用户对电动汽车电池性能的满意度

本研究对2018 - 2024年11525条插电式电动汽车（PEV）用户评论进行数据抓取和分析，重点关注用户对续航里程、电池退化和充电体验的电池性能满意度。通过使用SnowNLP、多项朴素贝叶斯和变形变压器（BERT）的双向编码器表示，以及可解释的机器学习算法，研究结果确定了位置和车辆价格是影响PEV感知的关键因素。在中国大陆，纯电动汽车（bev）获得的积极反馈一直高于插电式混合动力汽车（phev），尽管两者的满意度都随着车辆的使用年限而下降。纯电动行驶里程在100公里以下的pev在使用4年以上后，得到的评价大多是负面的。为了提高电动汽车的普及率和满意度，建议在二三线城市对150-200公里的插电式混合动力车和550-600公里的纯电动汽车实施有针对性的激励措施。这些发现为推动中国电动汽车市场增长的制造商和政策制定者提供了有价值的见解。

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
