Research on Energy Saving of New Energy Vehicle Transmission System based on Genetic Algorithm

With the improvement of environmental protection awareness and the increasing demand for new energy vehicles(NEV), the application of genetic algorithm in the transmission system optimization of NEV is of great significance. On the basis of the initial design, the transmission system optimized by genetic algorithm has been significantly improved. Among them, energy consumption is reduced by 20%(80 kWh), power performance is improved by 20% (from 100 kW to 120 kW), acceleration time is reduced by 20% (from 10 seconds to 8 seconds), and cruising range is increased by 25% (from 200 km to 250 km). Experiments show that genetic algorithm has achieved remarkable results in the optimization of transmission system of NEV, effectively improving energy utilization efficiency and power performance, and enhancing the endurance of electric vehicles. This research result has important guiding significance for promoting the technical progress and market popularization of the transmission system energy saving of NEV.
