A system includes a conversion device of a charging station, the conversion device 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, the 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 a first energy source impedance, control the conversion device to adjust a parameter of the first excitation signal to convert the first excitation signal to a converted excitation signal, apply the converted excitation signal to the energy storage system, detect a current response of the energy storage system, and estimate the impedance of the energy storage system based on the current response.
