CHINA REPORT
Accelera and Shaanxi Auto’s Dechuang Future have jointly developed a 31-ton Hydrogen fuel battery residue vehicle. Sixty Cummins Accelera Hydrogen fuel cell driven muck trucks were delivered and put into operation in Shanghai.
It is reported that this vehicle is matched with Cummins 125kW Hydrogen fuel battery engine system and 127kWh Lithium iron phosphate power battery, and uses the 410kW drive motor and AMT automatic transmission with ultra-low system energy consumption independently developed by Dechuang in the future to form a “new energy power chain,” so that the vehicle’s power performance indicators such as maximum speed, hill starting ability, climbing ability, loading capacity, etc. are higher than the industry average.
In the two years of cooperation, Cummins and Tec Future have jointly implemented an efficient vehicle energy management strategy to ensure the stable operation of Hydrogen fuel cell engines in efficient areas and reduce ineffective hydrogen consumption.
The area where the electrical efficiency of the system is more than 45% accounts for more than 70%, which promotes excellent performance of hydrogen consumption per hundred kilometers.

PSR Analysis: Heavy trucks are a major direction for the application of fuel cells in the transportation field, and fuel cell heavy trucks will be the main promotion and development direction for fuel cell vehicles in the future.
The production and procurement costs of fuel cell vehicles are very high, which limits their development. The overall purchase cost of vehicles is relatively high. The entire industry supply chain, including fuel cells, battery stacks, hydrogen systems, supporting electric drive systems, fuel cell vehicles, and matched power batteries, also has high costs.
Presently, without subsidies, the cost of using vehicles is still very high and has not reached the stage of vigorous development and use.
The overall coverage of a Hydrogen station is relatively low. Compared with a few years ago, there are many more Hydrogen stations now. Whether in the urban demonstration group or in the highway network, many Hydrogen stations have been established in the past two years. The absolute number is increasing, but in the whole market, it is far from meeting the requirements for the large-scale promotion and use of fuel cell vehicles, which is also a pain point restricting the use of terminals.
When fuel cell vehicles are put into social use and there is no fixed use line, there is a question about the layout and site selection of Hydrogen stations. This poses problems for our entire vehicle industry, and also for the development of hydrogen energy.
Another issue is that the overall technical level of the vehicle is relatively low. Currently, our products can only meet specific markets, routes, and needs, and must be continuously improved. PSR
