Measuring Online Battery AC Resistance Using a DC-DC Converter With Time and Frequency Hybrid Method

Measuring Online Battery AC Resistance Using a DC-DC Converter With Time and Frequency Hybrid Method

The estimation of battery state is important for ensuring the stability of batteries. The AC resistance of a battery is one of the factors used to estimate the battery state, and is measured using a Fast Fourier Transform (FFT), a technique that analyzes the frequency components. The power converter...
