A system includes a conversion device of a charging station connected to a first energy source of the charging station and a controller configured to perform an impedance measurement applied to an energy storage system selected from at least one of a second energy source of the charging station and a battery system of a vehicle. The controller is configured to cause the first energy source to generate a first excitation signal for measuring an impedance of the first energy source, control the conversion device to adjust a parameter of the first excitation signal to convert the first excitation signal into a converted excitation signal, apply the converted excitation signal to the energy storage system, detect a current response of the energy storage system, and transmit the current response to the energy storage system. And estimating an impedance of the energy storage system based on the current response.
一种系统包括充电站的转换设备和控制器,该转换设备连接到充电站的第一能量源,该控制器被构造为执行施加到能量存储系统的阻抗测量,该能量存储系统选自充电站的第二能量源和车辆的电池系统中的至少一个。控制器被构造为使第一能量源生成用于测量第一能量源阻抗的第一激励信号,控制转换设备以调节第一激励信号的参数以将第一激励信号转换为转换的激励信号,将转换的激励信号施加到能量存储系统,检测能量存储系统的电流响应,并基于电流响应估计能量存储系统的阻抗。
