Battery cabinet AC internal resistance

Ac internal resistance: The AC internal resistance is to inject sinusoidal current signal I=Imaxsin (2πft) into the positive and negative electrodes of the battery, and at the same time, by detecting the voltage drop U=Umaxsin (2πft+ψ) at both ends of the battery, the AC impedance of the battery can be derived; Generally, the sinusoidal AC current signal of 1kHz is input to the positive and negative terminals of the battery, and the parallel value of the Rp and Cp of the battery at this frequency is generally small (note: because the capacitor is approximately short-circuited under the high-frequency signal), which can be ignored.
