The series new energy locomotives can meet the green transformation needs of railway transportation in multiple fields such as steel, metallurgy, petroleum, chemical, mining, coal, power, and ports, making them an ideal choice for replacing outdated diesel locomotives.
Diverse: The locomotives are designed and developed based on the concepts of platformization, standardization, and modularization, enabling "menu-style" configuration. The power class covers 1000 kW to 2000 kW, with three selectable power options: "diesel engine + power battery," "power battery," and "hydrogen fuel cell + power battery." The functional modules of the locomotive are assembled in parallel and installed independently, enabling efficient customization and agile delivery.
Green: The locomotives feature green characteristics such as low emissions and low energy consumption. Compared with outdated diesel locomotives, the "diesel engine + power battery" locomotive can achieve an 83% reduction in carbon monoxide emissions, a 73% reduction in hydrocarbons, and a 45% reduction in nitrogen oxides. The "power battery" and "hydrogen fuel cell + power battery" configurations can achieve zero emissions.
Intelligent: The locomotives adopt microcomputer control and reserve interfaces for autonomous driving functions. By configuring systems such as video monitoring, environmental perception, and collision warning, remote control and autonomous driving can be realized. The locomotives can be equipped with a PHM (Prognostics and Health Management) system to enable fault perception, condition monitoring, and life prediction of the locomotive and key components, effectively extending maintenance intervals.
Reliable: The locomotives are equipped with vehicle-level and component-level safety protection for the power battery and hydrogen fuel systems, comprehensively ensuring the safety of the core power sources. The main components of the locomotives are carried over from mature models, achieving stable performance and safety and reliability. The structural strength of key load-bearing components such as the underframe and bogies has been comprehensively optimized and enhanced. Multiple power sources and power battery packs provide mutual redundancy, and the locomotive failure rate can be reduced by more than 10% compared with existing locomotives.
Economical: The locomotives adopt an efficient traction converter system, with maximum starting tractive effort exceeding 510 kN, a 17% increase in tractive effort year-on-year. Through optimal hybrid power control technology, the locomotives can ensure that the diesel engine always operates at the optimal economical speed. The application of regenerative braking energy feedback technology enables the "diesel engine + power battery" locomotive to achieve a fuel saving rate of more than 45%, with effective improvement in main transmission efficiency. In addition, the simplification and unification rate of key components exceeds 80%, enabling interchangeability and universal use of parts across different models, further reducing the variety of spare parts and lowering maintenance costs.
Comfortable: Compared with outdated diesel locomotives, the series new energy locomotives provide a more comfortable working environment for drivers and passengers. The net space of the driver's cab is increased by 40%, creating an extra-large "living space"; the lookout area is increased by 79%, providing an extra-large field of view. The use of power batteries and hydrogen fuel cells effectively reduces noise duration, and the noise level inside the driver's cab of the "diesel engine + power battery" locomotive can be reduced to below 70 dB.
