The invention provides an electric vehicle wireless charging primary side topology adaptive control method and system, and the method comprises the steps: Step 1, maintaining an initial state, and detecting whether there is an electric power entering a charging region through a current; step 2, switching to an LCC topological state, judging a topological structure of a receiving end through current detection, if the receiving end is of a P-type structure, switching to an S topological state, and charging on time according to a first pricing standard; if the receiving end is of the LCC type structure, the LCC topology state is maintained, and charging is carried out on time according to a second pricing standard; if the receiving end is of an S-shaped structure, the LCC topology state is maintained, and charging is carried out on time according to a third pricing standard; 3, detecting whether the electric vehicle is separated from the charging state, and if the electric vehicle is separated from the charging state, ending charging; the wireless charging system has the advantages that the wireless charging system can be used for static wireless charging and dynamic wireless charging and can adapt to electric automobiles with different secondary side topological structures, and the compatibility and rationality of the system are higher by changing the primary side topological structure and the pricing mode.

    本申请提供一种电动汽车无线充电原边拓扑自适应控制方法及系统,包括步骤:Step1:维持初始态,通过电流检测是否有电动进入充电区域;Step2:切换至LCC拓扑态,通过电流检测判定接收端的拓扑结构,如果接收端是P型结构,则切换为S拓扑态,按第一计价标准按时计费;如果接收端是LCC型结构,则维持LCC拓扑态,按第二计价标准按时计费;如果接收端是S型结构,则维持LCC拓扑态,按第三计价标准按时计费;Step3:检测电动汽车是否脱离充电状态,如果脱离,则充电结束;其效果是:既可用于静态无线充电,又可用于动态无线充电,能够适应不同副边拓扑结构的电动汽车,通过改变原边拓扑结构和计价方式,使得系统的兼容性和合理性更强。
