Study on Energy-saving Scheme of Electric Bus and Analysis of Simulation Process
This paper investigates the characteristics of the powertrain system and the hydraulic energy-saving subsystem of a pure electric urban bus during coasting and braking processes,aiming to further improve the vehicle's energy recovery efficiency.The study finds that the vehicle's drive motor can effectively recover braking energy by acting as a generator to charge the battery during coasting.Meanwhile,by reasonably configuring the parameters of the hydraulic system and optimizing the design of hydraulic components,hydraulic technology can further recover the vehicle's braking energy.Through AMESIM software simulation and analysis,the feasibility of hydraulic technology in energy re-covery is verified.The results show that the optimized hydraulic energy-saving subsystem can signifi-cantly improves the vehicle's energy recovery efficiency,providing an effective technical approach for the energy saving and emission reduction of electric buses.In addition,the study also explores the interac-tion between various parameters in the hydraulic system,providing a theoretical basis for further opti-mization of the hydraulic energy-saving subsystem.This research provides valuable references for the development of energy-saving technologies for pure electric urban buses.
