The University of California, San Diego, has responded to the growth of Electric Vehicle (EV) ownership by continually adding charging stations all around campus over the past five years. In March 2020, the coronavirus pandemic caused a massive decline in EV charging as shelter-in-place orders were issued and the campus closed except for the medical centers. Overall, EV charging energy demand decreased by over 73%. But the decrease was uneven as direct current fast charger (DCFC) stations and the charging stations at the university's medical centers took on a larger percentage of the total campus load. Charging energy provided at the nonmedical stations decreased by 84%, while it decreased 50% at medical stations and 67% at DCFC stations. DCFC showed the strongest recovery in charging energy during the shutdown. The distribution of charging energy during the day and the charging duration did not change during the shutdown, while the plug-in duration increased. Implications for decarbonizing the transportation and electrical power systems are discussed.

冠状病毒大流行对电动汽车工作场所充电的影响

加利福尼亚大学圣地亚哥分校在过去五年中不断在校园内各处增加充电站,以应对电动汽车(EV)拥有量的增长。2020年3月,冠状病毒大流行导致EV充电大幅度下降,因为发出了就地庇护令,除了医疗中心外,校园也关闭了。总体而言,电动汽车充电能源需求下降了73%以上。但是,由于直流快速充电器(DCFC)站和大学医疗中心的充电站占据了校园总负载的较大比例,因此下降幅度并不均匀。非医疗站提供的充电能量减少了84%,而医疗站减少了50%,DCFC站减少了67%。在停机期间,DCFC的充电能量恢复最为强劲。在关闭期间,白天的充电能量分配和充电持续时间没有变化,而插入持续时间却增加了。讨论了对交通运输和电力系统除碳的意义。
