Description

technical field [0001] The invention belongs to the technical field of driving and regenerative braking control of pure electric vehicles, and in particular relates to a predictive control system for energy management of a composite power supply of pure electric vehicles. Background technique [0002] With the increasingly serious energy crisis and environmental pollution, electric vehicles have been highly valued by the industry and strongly supported by government departments due to their advantages of energy saving, environmental protection, and high energy conversion efficiency. At present, an important factor restricting the development of electric vehicles is their short driving range. How to improve the energy utilization efficiency in the driving process and the braking energy recovery efficiency is of great significance. [0003] Most of the current electric vehicles use a single energy structure. During the driving process of electric vehicles, frequent acceleratio...
