Green Power · Intelligent Leadership for the Future | Fosen Technology's Diesel-to-Electric Locomotive Solution
Driven by the national "Dual Carbon" strategy and the equipment renewal policy of the Ministry of Industry and Information Technology, the green transformation of traditional diesel locomotives is imminent.
Relying on the strong scientific research strength of Central South University, Fosheng Technology conducts research on the new energy engineering application and optimization of rail transit and engineering vehicles, as well as artificial intelligence and fault diagnosis.
The company actively promotes the new energy upgrading of high energyconsuming and highemission locomotives, providing a new choice of clean power for industrial, mining and railway transportation.
I. Three Core Advantages
High-Performance Battery System
Adopting CATL and BYD power batteries specially designed for railway applications, equipped with a threelevel masterslave BMS architecture. A single system provides a capacity ranging from 90 kWh to 1000 kWh, with the complete machine system reaching a maximum capacity of 4506 kWh, enabling flexible configuration.
It supports liquid-cooled super-fast charging, rapid battery swapping, and range-extended recharging for hassle-free energy replenishment.
With adaptive DC variable frequency technology, the battery thermal management system features lower energy consumption.
Dual automatic fire suppression systems inside and outside the battery pack are installed for ultimate safety.
High-Efficiency Electric Drive Technology
Adopting high-power-density liquid-cooled permanent magnet synchronous motors and electric drives with a compact structure and flexible layout.
It supports multilevel rated power configurations from 180 kW to 2400 kW to adapt to various traction demands, featuring high torque, low noise, and high reliability.
Integrated control of traction, braking, and energy recovery is realized through an intelligent electronic control system.
Intelligent Control and Operation & Maintenance
Equipped with a visualized hierarchical fault diagnosis system, an intelligent humanmachine interaction system, a remote monitoring platform, and an autonomous driving interface.
It realizes functions including flexible starting, adhesion control, balanced multi-motor power distribution, braking energy recovery, and active braking.
II. Typical Cases
The solution has been successfully applied in multiple projects of central stateowned enterprises, covering traction requirements ranging from 110 tons to 5,200 tons.
Among them, locomotives delivered to China Energy Engineering Group (CEEC) in November 2023 have achieved zerofault operation for more than 300,000 kilometers, reducing operation and maintenance costs (including energy consumption, maintenance, etc.) by approximately 80%.
III. Cooperation Ecosystem
Fosheng Technology maintains in-depth cooperation with Central South University.
Relying on the State Key Laboratory of Heavyduty, Highspeed and Highpower Electric Locomotives, we integrate multidisciplinary strengths from industry, universities and research institutes.
Together with leading enterprises including CATL, BYD and CRRC, we provide customers with fullchain support ranging from solution design, renovation implementation to operation and maintenance services.
