Discuss on heavy-duty trucks development technology path and electrification process
In recent years,China's heavy-duty truck production and sales volume has entered a stage of downward shock and deep adjustment and the optimization of power composition has accelerated.Under the background of the two national strategies of dual carbon goals and automobile electrification,China's heavy-duty trucks are undergoing a gradual transition from fuel vehicles to electric and hydrogen heavy-duty trucks.The economy of each technology path directly affects its development speed and development scale,heavy-duty trucks of different technology paths have their own advantages in the actual use process,and the policy level's development guidance and support for each technology path are obviously different.The paper proposes that the future of optimizing the power composition of heavy-duty trucks in China will be significantly accelerated and LNG heavy-duty trucks will continue to be the main alternative to diesel heavy-duty trucks in the short term,electric heavy-duty truck sales will increase significantly,and hydrogen fuel cell heavy-duty trucks will continue to maintain small-scale growth expecting to achieve the significant breakthrough during the 15th Five-Year Plan.It is recommended to steadily promote the electrification of heavy-duty trucks along the approach to oil-gas(LNG-based)-electricity-hydrogen.
