Simulation for it Parallel-series Hydnttlic Energy-saving Vehicles Energy Management Mode
In this thesis, the operation mode of a kind of Parallel-Series HEV(Hydraulic Energy-saving Vehicles) is analyzed, the system efficiency models for tht HEV at the charging and discharging mode were proposed based upon the engine efficiency map, motor/generator efficiency map and battery efficiency map. The maximum system discharging efficiency is taken as the optimal objective of the discharging operation mode, while the charging operation mode, according to different charge states of the storage battery, takes the maximum system charging efficiency and the maximum product between the system charging efficiency and the charging power as the optimal objective respectively; and the energy management stategy of the drive hybrid system optimized and studied, resulting in the best controlling torque and speed of the engine, electric motor and dynamo of vehicles under different operation circumstances, The emulation result of the fuel economical efficiency shows that the fuel consumption or this drive hybrid system under the cycle operaticn mode of NEDC is reduced by 36.94 ％.
