| Abstract: | To meet the requirements in the performance of hybrid electric vehicle and improve its efficiency in energy utilization,the strategy of energy management is studied.According to the energy relationship between power units and loads,and based on the relationship between battery pack SOC and charging/discharging properties,management is integrated considering both fuel consumption optimal control for the engine and constant SOC control for the battery pack.It is validated by a series of experiments on a prototype vehicle.The results indicated that the battery pack could be kept in the best working conditions and the fuel economy was improved by about 8%. |
