General Secretary Xi Jinping proposed that the development of new energy vehicles is the only way for my country to move from a big automobile country to a powerful automobile country. Subsequently, under the guidance of policies, my country's auto industry took the lead in starting the electrification transformation and achieved a good first-mover advantage. At present, under the guidance of the carbon neutrality goal of peak carbon, my country's commercial vehicle field is facing a "decarbonization" revolution, and the creation of green, low-carbon and intelligent commercial vehicle products has become the goal that major companies are striving to pursue.

       Everyone, it is customary to divide commercial vehicles into two categories: passenger cars and trucks. Commercial vehicles include all trucks and passenger cars with more than 9 seats, and are divided into five categories: passenger cars, trucks, semi-trailer tractors, incomplete passenger vehicles and incomplete trucks.

       Large-scale buses operate in cities, with a daily operating mileage of less than 300 kilometers, each trip within 50 kilometers, and each trip has an interval of 15-30 minutes. This feature is the basic background that large buses can realize electrification.

       Other commercial vehicles are all trucks, especially long-distance trucks, whose daily operating mileage is basically 500-800 kilometers, and some have to run more than 1,000 kilometers. As far as the current specific energy level of power batteries is concerned, it is basically impossible for large trucks to be electrified, and it is basically impossible to copy the practice of large pure electric buses. In fact, there is no successful case of pure electrification for long-distance buses at present. (test article)
