摘要

Medium- and heavy-duty vehicle electrification and the utility grid. When most people think about vehicle electrification, they invariably think about electric cars. This shouldn't be surprising - the most popular brand of electric automobiles shipped nearly half a million vehicles in 2020. However, when looking at ways to improve air quality, electrifying medium- and heavy-duty (M/HD) vehicles is an obvious place to start. Even though they make up only 4.6 percent of the total vehicles, M/HD vehicles (gross vehicle weights of over 10,000 lbs.) produce nearly 40 percent of transportation sector air pollution. The number of M/HD vehicles is also climbing, even as the number of light-duty (L/D) vehicles such as passenger cars, sport-utility vehicles (SUVs), and light trucks, is declining.
