All-electric vehicles remain far from reaching the market share required to meaningfully reduce transportation-related CO₂ emissions. While financial and technological adoption barriers are increasingly being removed, psychological barriers remain insufficiently addressed. Here we show that car owners systematically underestimate the compatibility of available battery ranges with their annual mobility needs and that this underestimation is associated with increased demand for long battery ranges and reduced willingness to adopt electric vehicles. We tested a simple intervention to counteract this bias: providing tailored compatibility information reduced range concern and increased willingness to pay for electric vehicles with battery ranges between 60 and 240 miles, relative to a 50-mile-range baseline model. Compatibility information more strongly increased willingness to pay than did information about easy access to charging infrastructure, and it selectively increased willingness to pay for car owners who would derive greater financial benefits from adopting an electric vehicle. This scalable intervention may complement classical policy approaches to promote the electrification of mobility.

全电动汽车仍远未达到有效减少与交通相关的 CO _{2所需的市场份额}排放。虽然财务和技术采用障碍越来越多地被消除，但心理障碍仍未得到充分解决。在这里，我们表明，车主系统地低估了可用电池续航里程与其年度出行需求的兼容性，并且这种低估与对长续航里程的需求增加和采用电动汽车的意愿降低有关。我们测试了一种简单的干预措施来抵消这种偏见：相对于 50 英里范围的基线模型，提供定制的兼容性信息可以减少对续航里程的担忧，并增加对电池续航里程在 60 到 240 英里之间的电动汽车的支付意愿。兼容性信息比有关轻松访问充电基础设施的信息更能增强支付意愿，它选择性地增加了为那些将从采用电动汽车中获得更大经济利益的车主付费的意愿。这种可扩展的干预措施可以补充传统的政策方法，以促进移动电气化。
