插电式混合动力汽车能量管理仿真分析

Simulation Analysis of Energy Management of Plug-in Hybrid Vehicles

随着全球汽车保有量的急剧增加,随之而来的是一系列能量短缺和环境污染问题。混合动力汽车具有纯电动汽车和传统燃油车的优点,即有较长的行驶里程且排放较低。文章以插电式混合动力汽车为研究对象,运用纵向动力学相关知识搭建整车的仿真模型,以经典的规则策略控制发动机和电机的能量分配,系统分析电量消耗阶段(Charge Depleting Cycle,CD)、电量维持阶段(Charge Sustaining Cycle,CS)、电池荷电状态(State of Charge,SOC)、电机和发动机的转矩转速、制动力矩分配以及发动机单工况和百公里等效油耗,说明插电式混合动力汽车的性能优于传统燃油汽车。

With the rapid increase in global car ownership,a series of energy shortages and environmental pollution problems have emerged.Hybrid electric vehicles are a combination of pure electric vehicles and traditional fuel vehicles,combining the advantages of both,reducing emissions while also having sufficient driving range.This article takes plug-in hybrid electric vehicles as the research object,and uses longitudinal dynamics knowledge to build a simulation model of the entire vehicle.The classic rule strategy is used to control the energy distribution of the engine and motor.The system analyzes the Charge Depleting Cycle(CD)and Charge Sustaining Cycle(CS)conditions,battery SOC,motor and engine torque,braking torque distribution,and equivalent fuel consumption of the engine under single working condition and 100 kilometers.This demonstrates the superiority of plug-in hybrid vehicles in terms of performance compared to traditional fuel vehicles.
