1) The operational principle of the small signals in this study shows that the battery sinusoidal variations in the output voltage is the result of an AC small-signal sinusoidal input current. 2) Battery satisfies the three small-signal measurement conditions (stability, causality, and linearity), which are mathematically proven in this work.
A sinusoidal input is modulated on top of a precisely generated DC reference to measure the frequency response of the battery being tested. Another part of this test system is the measurement system of the small-signal model parameters, which is designed to record battery frequency response and evaluate model parameters.
