As global pressure to reduce emissions increases, markets such as China and Europe have introduced subsidy policies for new energy commercial vehicles. Recently, domestic leading car companies such as **FAW Jiefang and Shaanxi Automobile Heavy Duty Truck** have successively released pure electric semi-trailer models with a range of more than 300 kilometers, focusing on short-distance transportation scenarios such as ports and mining areas. Industry insiders predict that the sales volume of new energy semi-trailers may increase by 50% year-on-year in 2024.
