| Summary: | Energy and environment are the common concern of all countries in the world today. Transportation is an important field of energy consumption and pollution emissions. The development of new energy vehicles is an important measure to ease the energy crisis and reduce pollution emissions. In recent years, with the support and encouragement of national policies, China’s new energy vehicle industry has developed rapidly, especially in the field of passenger vehicles. There are a large number of excellent enterprises and products, and the development direction is relatively clear, but the technical route in the field of commercial vehicles, especially road freight, is not yet clear. Heavy lorries account for 6.6% of the total vehicle population in China, but their carbon emissions account for more than 50%, nitrogen oxide and particulate matter emissions account for 75% and 50% respectively. Heavy lorry is key vehicle type for energy conservation and emission reduction. In this paper, three possible schemes of heavy lorry electrification, i.e. battery swap scheme, hydrogen fuel cell scheme and electrified highway scheme, were analyzed. The three schemes have different characteristics and are suitable for different scenarios. At present, they all have their own technical bottlenecks. Hydrogen fuel cell scheme has good application prospects in long-distance freight transportation. In the short-distance freight transportation with irregular routes, battery swap scheme has more advantages. In the medium and short-distance transportation with fixed routes, electrified highway scheme is superior to battery swap scheme. |
