2. Main Achievements and Contributions

2.1 Contributions to Advancing the Industrialization of China’s New Energy Vehicle Sector

Wang Jia has been engaged in new energy vehicle development since 2006. With 18 years of experience in new energy vehicles (construction machinery) and core components, he experienced China’s new energy vehicle progression from its nascent stage to rapid advancement and made the following key contributions.

2.1.1 Advancing the Industrialization of New Energy Passenger Cars

From 2006 to 2009, he was responsible for the development of new energy vehicles at Haima Automobile Group, in conjunction with the national key project on energy-saving and new energy vehicles undertaken by Haima Automobile, titled “Research on Key Technologies for Manufacturing Haima Electric Passenger Cars.” He led the development of the Haima Aishang electric passenger car. In 2007, this model passed the frontal crash test at the Changchun Motor Vehicle Inspection Center, marking it as the first A00-class pure electric passenger car in China to pass such a test. The model was launched in 2011 and has since sold over 50,000 units, with no major safety accidents reported. In 2009, he led the collaboration between Haima Group and Bosch Germany on the micro-hybrid power system, achieving successful mass production in Haima models.

2.1.2 Advancing the Industrialization of Key Components in Renewable Energy

From 2017 to 2021, he led the development of the onboard charging systems, achieving total sales of over 100,000 units. The 3.3kW fully sealed onboard charging system achieved an IP68 protection rating and a system efficiency of 93%, setting a domestic benchmark.

2.1.3 Contributing to the National Research on New Energy Vehicle Development Strategies

From 2015 to 2017, while serving as a postdoctoral fellow at Tsinghua University’s School of Vehicle and Transportation Engineering, he assisted my mentor, Academician Ouyang Minggao, in completing the research and revision of subsidy policies. By conducting in-depth research into complete vehicles and component enterprises, he gained insights into the costs and industrial scale of complete vehicles and three-electric components, proposed suggestions for the adjustment of national subsidy policies, and fostered the high-quality development of the new energy vehicle industry. As the principal author, he took part in the Chinese Academy of Engineering’s advisory project “Automotive Powerhouse Strategy Research,” where he was in charge of authoring the section on new energy vehicle strategic development research. The research results were published by the Science Press in 2020.

2.2 Advancing the Use of Hydrogen Fuel Cells in Construction Machinery

In 2021, Wang Jia joined Jiangsu XCMG Group and served as the director of XCMG Group’s Shanghai Research Institute, responsible for the development of new energy construction machinery. Through creative development of hydrogen fuel cells for construction machinery, his team has made breakthroughs in durability, environmental adaptability, and integration, elevating our product performance indicators to globally advanced standards. Additionally, this was applied in the industrialization of XCMG’s 80T hydrogen fuel mining trucks.

XCMG Group is the number one construction machinery enterprise in China and third in the world. The “XCMG Hydrogen Energy Technology Development Plan,” which he authored, received approval at the group’s executive meeting in 2022. XCMG Group will actively promote the application of hydrogen energy in the field of construction machinery. In 2023, addressing specific application scenarios in construction machinery, he led the development of hydrogen fuel cell systems for construction machinery, filling an international gap with their product. This product has achieved breakthroughs in terms of high durability, superior environmental adaptability, and elevated integration, following the evaluation and analysis of conditions including the compact structure of construction machinery, significant vibration impacts, extreme cold, high altitudes, intense dust, and cyclical variable load conditions. These have been translated into product development metrics like boundary dimensions, vibration impact, performance, and environmental adaptability. Advanced control algorithms are developed to address pre and post strategies for variable load indicators, cathode loop decoupling control algorithms for MIMO systems, and IMC internal model control algorithms for temperature control with significant hysteresis characteristics, etc. These algorithms, after numerous rounds of calibration and optimization, ultimately meet the design specifications. In 2023, the specialized hydrogen fuel cell system for construction machinery was implemented in XCMG’s 80T mining trucks, fulfilling the vehicle’s operational requirements. To protect intellectual property rights, 29 domestic and international invention patents have been arranged around core technologies in areas such as the electric stack, electronic control, hydrothermal management, hydrogen system, and air system. By 2030, it is anticipated that the mass production scale of hydrogen fuel cell construction machinery will surpass 50,000 units, with a production value exceeding 20 billion yuan (RMB).

2.3 Contributions in Promoting Sino-European Cooperation in the Development of New Energy Technologies

2.3.1 Research and Implementation of Key Technologies for All-electric Compact Excavators Tailored for the European Market

In 2021, XCMG Research Institute collaborated with XCMG European R&D Center to develop all-electric mini excavators for the European market. Use 1.5-ton, 2.0-ton, and 2.7-ton electric mini excavators as the carriers, overcoming the shared critical technologies of electric mini excavators. Achieving national benchmark levels in terms of electric drive power and other indicators across the series of all-electric compact excavator products. Addressing the European market’s regulatory requirements for the admission of electric drive systems in all-electric compact excavators, undertake market surveys and interpretation of CE regulatory standards. Organize supervisory regulations and market entry specifics for all-electric compact excavators in the European market, formatting a technical guide for the development of electric drive systems. Setting up a development workflow for electric drive systems in all-electric compact excavators that complies with European market standards. Break through the motor pump power adaptive platform control technology, implementing automatic idling and auto start-stop for the motor pump system. Develop motor control based on the performance MAP for optimal efficiency, reducing electrical energy loss and the total installed power capacity of the machinery. Through testing the XE27 prototype, the whole machine’s electricity consumption is 9.27 kWh/hour, and the operational time extends to 4.89 hours. By the year 2025, sales are projected to reach 1350 units. By 2030, sales are expected to surpass 10000 units. This initiative establishes robust groundwork for the expansion of XCMG construction machinery products in the European market.

2.3.2 XCMG-Bosch Strategic Alliance in Fuel Cell Technology

Bosch Group, a globally recognized corporation, has established an early presence in the hydrogen fuel cell sector. Its components such as fuel cell stacks, air compressors, and hydrogen pumps are known for their superior performance. In 2022, XCMG Group entered a strategic partnership with Bosch Group in the field of hydrogen fuel cells. Collaboratively developed hydrogen fuel cell products tailored for construction machinery applications. The 140kW hydrogen fuel cell system uses Bosch’s 170kW fuel stack. The prototype has been fully developed. It has attained a peak efficiency of 61%, achieving a globally advanced standard. This system will be integrated into XCMG mining machines, XCMG loaders, and other construction machinery products promoted globally. With the proposal of international carbon neutrality goals, the European Union has issued the “European Green Deal”, aiming to reduce greenhouse gas emissions by 55% by 2030 (compared to 1990) and plannings to achieve carbon neutrality by 205. Wang Jia will continue to devote himself to the development and promotion of new energy vehicles and construction machinery products to contribute to the deepened collaboration in the Sino-European new energy sector and to offer my own efforts.
