论文摘要
联盟19日大流行使全国的总体流动性降低了。看到的变化反映了对新的Covid-19案例，当地健康指南和季节性的反应，这使得流动性与Covid-19之间的关系从地区到地区独特。本文介绍了Covid-19之后的电动汽车（EV）充电和活动性的数据驱动案例研究。研究表明，在第一次COVID-19案出现在犹他州，每天消耗的电动汽车充电会和总能量的数量下降了40％。相比之下，每次充电课程消耗的能量在同一时期仅下降了8％，并且会议的开始和结束时间在全年中保持一致。尽管在第一波Covid-19病例中，EV移动性比总车辆移动性降低了，尽管新感染有巨大的第三波浪潮，但返回的速度较慢，返回的速度较慢，恢复到平均值接近其平均值。
The COVID-19 pandemic has depressed overall mobility across the country. The changes seen reflect responses to new COVID-19 cases, local health guidelines, and seasonality, making the relationship between mobility and COVID-19 unique from region to region. This paper presents a data-driven case study of electric vehicle (EV) charging and mobility in the wake of COVID-19. The study shows that the number of EV charging sessions and total energy consumed per day dropped by 40% immediately after the arrival of the first COVID-19 case in Utah. By contrast, the energy consumed per charging session fell by just 8% over the same periods and the distribution of session start and end times remained consistent throughout the year. While EV mobility dropped more dramatically than total vehicle mobility during the first wave of COVID-19 cases, and returned more slowly, both returned to stable levels near their mean values by September 2020, despite a dramatic third wave in new infections.
