我们提供了第一个电动汽车(EV)家用充电的规模估计。之前的估计是基于相互矛盾的调查，或者是从拥有专用电动汽车电表的小样本家庭中推断出来的。我们将数十亿小时电表的测量值与加州家庭的地址级电动汽车注册记录结合在一起，其中包括64,000名电动汽车车主。电动汽车平均每天增加家庭总负荷2.9千瓦时，远低于州监管机构假设的一半。结果表明，电动汽车靠电力行驶的时间比预期的要少，这引发了对气候政策交通电气化的质疑。
We provide the first at-scale estimate of electric vehicle (EV) home charging. Previous estimates are based on conflicting surveys or are extrapolated from a small, unrepresentative sample of households with dedicated EV meters. We combine billions of hourly electricity meter measurements with address-level EV registration records from California households, including 64,000 EV owners. The average EV increases overall household load by 2.9 kilowatt-hours per day, well under half the amount assumed by state regulators. Results imply that EVs travel less than expected on electric power, raising questions about transportation electrification for climate policy.
