Researchers Develop Genetic Algorithm-Based Energy Management Strategy for Fuel Cell Hybrid Electric Vehicles

Researchers from the University of Science and Technology of China have developed a genetic algorithm-based energy management strategy for fuel cell hybrid electric vehicles. This strategy, designed to minimize the overall operating cost of the system, involves establishing dynamic and static models of the hydrogen-electric hybrid vehicle, as well as an aging model. The researchers employed a genetic algorithm to dynamically search for the optimal equivalence factor within the cost function, optimizing the system's economic performance while ensuring real-time feasibility. The proposed strategy significantly enhances both the durability and fuel economy of the fuel cell hybrid vehicle.
