摘要
电动汽车锂离子电池无线充电方式相比于接触式充电方式具有可靠安全等优点.本文在分析锂离子电池典型充电过程的基础上,通过对无线电能传输原理及谐振网络拓扑结构的研究,提出了基于SS与PS复合式谐振拓扑的电动汽车锂电池无线充电系统.在电池等效负载变化情况下,SS拓扑结构可实现恒流模式,PS拓扑结构可实现恒压模式,在理论分析的基础上对系统参数进行了设计.通过Matlab仿真系统搭建仿真模型,验证了恒流和恒压的充电模式,且在两种拓扑结构切换过程中,充电电压和充电电流过度平缓,符合电动汽车锂离子电池的充电特性.
Compared with the contact charging method,the wireless charging method of electric vehicle lithium-ion battery has the advantages of reliability and safety.According to the typical charging process of lithium-ion battery of electric vehicle,through the study of radio energy transmission principle and resonant network topology,a wireless charging system of lithium-ion battery of electric vehicle based on SS and PS composite resonant topology is proposed in this paper.When the battery equivalent load changes,SS topology can realize constant current mode and PS topology can realize constant voltage mode.The system parameters are designed on the basis of theoretical analysis.The simulation model is built through the MATLAB simulation system to verify the charging mode of constant current and constant voltage.In the process of switching between the two topologies,the charging voltage and charging current are too gentle,which is in line with the charging characteristics of lithium-ion battery of electric vehicle.
