摘要
针对电动汽车车载电池在充电过程中需要先进行恒流充电,一段时间后再进行恒压充电,而现有的电动汽车无线充电技术中无法同时兼顾恒流与恒压2种特性,提出一种具有恒流恒压充电功能的电动汽车ICPT系统,其利用双向开关能够实现恒流与恒压2种输出特性,很好地解决了电池恒流恒压充电问题。首先对系统进行了深入的理论研究,推导了2种模式下的数学基础以及切换机制,并给出了系统设计方法,最后通过实验验证了理论研究的正确性以及技术实施的可行性。
For the vehicle-mounted battery,constant current charging is required during the charging process,and after a period of time,constant voltage charging is performed.However,the current electric vehicle wireless charging technology cannot simultaneously take into account both the constant current and the constant voltage characteristics,so an electric vehicle ICPT system with a constant current and constant voltage charging was proposed.The system could realize both constant current and constant voltage output characteristics using a bidirectional switch,which solved the problem of constant current and constant voltage charging of the battery.Firstly,a profound theoretical research on the system was made,the mathematics basis and switching mechanism in two modes were deduced,and the system design method was given.Finally,it verifies the correctness of theoretical research and the feasibility of technical implementation through experiments.
