摘要

一位在能效声明方面有超过45年经验的工程师将带您看看电动汽车是否比内燃机驱动的传统汽车更高效。他发现，电动汽车的效率略高于它们所要取代的技术。然而，很多改进的潜力取决于电力来自哪里以及车辆如何充电。

Taking the Measure of Electric Vehicles

An engineer with more than 45 years’ experience on efficiency claims takes a look at whether electric vehicles are much more efficient than conventional cars powered by internal combustion engines. He found that EVs are marginally more efficient than the technology they are positioned to replace. A lot of the potential for improvement is, however, contingent on where the electricity comes from and how the vehicles are charged.
