Battery Internal Resistance Detection Based on AC Injection Method
The internal resistance of a Lithium-ion battery(LIB) is an important parameter to indicate state of health (SOH). However, the battery internal resistance could not be measured directly, and it is also influenced by temperature and current rate. Therefore, how to obtain the internal resistance of the battery quickly and accurately …
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
