Motivations to use vehicle-to-grid (V2G) charging stations for electric vehicles, 2021

Results of a study conducted within the Horizon 2020 project, ebalance-plus: Energy balancing and resilience solutions to unlock flexibility and increase market options for distribution grid. The survey was conducted in December 2021 on a sample of 4,000 individuals in four countries: France, Italy, Denmark and Spain (1,000 in each). The survey was conducted in the form of a self-completed online questionnaire (computer-assisted web interview) and covered topics related to household electricity use, evaluation of the user interfaces of energy management devices and electric vehicle charging systems, evaluation of messages that build energy literacy, and evaluation of the V2G charging concept. The study sample comprised adults (mean age: 43) who are responsible for paying electric bills or purchasing electrical appliances for their homes, and who use smartphones daily. The sample was gender balanced and stratified by age, city size, region, and education level. This research is part of a project that has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No.864283.本研究成果源自欧盟地平线2020（Horizon 2020）框架下的ebalance-plus项目，该项目旨在研发能源平衡与韧性解决方案，以解锁配电网灵活性并拓展其市场应用场景。本次调研于2021年12月开展，共在法国、意大利、丹麦、西班牙四个国家各选取1000名受访者，总样本量达4000人。本次调研采用自填式在线问卷（计算机辅助网络访谈，computer-assisted web interview）形式开展，调研内容涵盖家庭用电相关议题、能源管理设备与电动汽车充电系统的用户界面评估、能源素养培育相关宣教内容的效果评估，以及车辆到电网（Vehicle-to-Grid，V2G）充电理念的用户评价。本次调研的受访者均为成年人，平均年龄为43岁，需负责家庭电费缴纳或家电采购，且每日使用智能手机。该样本性别分布均衡，并按照年龄、城市规模、区域及教育水平进行分层抽样。 本研究隶属于获得欧盟地平线2020研究与创新计划资助的项目，该项目的资助协议编号为864283。
