Under the background of national implementation of the "dual carbon" target, with the gradual maturity of the "three-power" technology, the manufacturing cost of electric products is decreasing continuously. As a means of production, construction machinery becomes more and more attractive and economical than the whole life cycle cost of fuel, and the trend of electric construction machinery is gradually approaching. The sub-categories applicable to closed and fixed working environments such as ports, urban construction and mines have taken the lead in electrification. The demand for electrification of mainstream construction machinery such as excavators is expected to grow rapidly between 2024 and 2025. The demand for renewal and replacement is expected to support the demand of domestic construction machinery industry. At the same time, the rapid development of electronization is expected to highlight the competitive advantages of domestic main engine factories, and more conducive to the global development of main engine enterprises.
Policy catalysis + tri-electric technology tends to be mature, and the construction machinery industry is expected to speed up the process of electronization. In 2018, the Ministry of Ecology and Environment issued the Technical Policy for Prevention and Control of Pollution from Non-road Mobile Machinery, encouraging the application of new energy technologies such as hybrid power, pure electric power and fuel cell in non-road mobile machinery, giving priority to the development of new energy sources for small and medium-sized non-road mobile machinery, and gradually achieving ultra-low emissions and zero emissions. In 2020, the Ministry of Industry and Information Technology issued the Action Plan for Promoting Electricization of Vehicles in Public Areas to promote the electronization of construction machinery and accelerate the transformation of construction machinery industry to new energy sources. Therefore, under the background of realizing the goal of "two carbon" and building a new double cycle development pattern, with the maturity of domestic "three power" technology and the continuous reduction of manufacturing costs, the whole life cycle cost of construction machinery electronization or gradually becoming attractive and economic, electronization has become one of the important directions for the green development of construction machinery.
The segmentation suited to application scenarios such as enclosed and stationary work environments has taken the lead in moving to electronics. For example, Sany Heavy Industries, Xugong Group, Zhonglianke, Shandong Lingong, Liugong Machinery and other enterprises launched urban construction vehicles such as dregs and soil transporters, concrete mixers, loaders, aerial working platforms, while Sany Group, Xugong Group, Zhonglianke, Tongli Heavy Industries launched electric port tractors, mine cards, mining dumpers and other vehicles. Therefore, after communicating with the main engine factory, the author predicts that the segment under specific application scenarios from 2022 to 2023 is expected to welcome the rapid growth of electric products, and the demand of mainstream construction machinery such as excavators is expected to grow rapidly between 2024 and 2025. According to GGII, the power consumption of construction machinery is high, and the average installed capacity of lithium battery per machine is about 5 times that of ordinary new energy vehicles. In 2025, the demand for lithium battery with 30% lithium permeability is 30 GWh. During the 14th Five-Year Plan period, shipments of lithium batteries for power storage in China will exceed 60GWh, and the lithium battery market will formally enter a period of accelerated development.
"The electronization market has shown a competitive situation, with new strategies and new product layouts emerging in an endless stream. In November alone, many main engine factories have launched a number of countermeasures. For example, on November 26, the new technology launch of Zhonglianke New Energy Products was held at Zhonglianke Lugu Industrial Park, and 16 new energy products of 8 large series appeared centrally, including the world's first pure electric pump vehicle." The world's first 60-meter class hybrid pump truck, the world's largest 118-ton off-highway pure electric wide-body dump truck, etc. On Nov. 23, Sany Heavy Industries'first intelligent power exchange station appeared, and the task of power exchange was completed within 5 minutes. Various vehicles, such as heavy cards, dumpers, mixers and loaders, were adapted to meet the power exchange requirements of Sany Heavy Industries' various electric equipment. On November 26, Liu Gongjian's anniversary day showcased new electrified products such as electric loaders, excavators, wide-body vehicles and road rollers.
