However, selecting an inductor with suitable inductance is no simple process, where the inductance value should be adequate to minimize the circulating current as well as to reduce an extra voltage drop on the inductors that affects the terminal voltage
. This difficulty can be circumvented by using a multiwinding coupled inductor.
And [I.sub.S] is the current pass through the capacitance [C.sub.S], [I.sub.L] is the load current (positive for discharging state and negative for charging state), and [U.sub.L] is the terminal voltage
. Among them, the open-circuit voltage [U.sub.OC] describes the voltage characteristics of the battery, and the capacitance [C.sub.S] describes the capacity characteristics of the battery.
The first type consumed the redundant energy of parallel resistance to maintain the terminal voltage

The outputs of the lithium ion battery model are the battery terminal voltage
; the battery cell temperature; the battery SOC; and also the increased SEI thickness and the decreased battery capacity, both of which indicated SOH of the battery.

The back EMF waveform from the zero crossing point is measured indirectly from the three terminal voltage

The parameters are as follows: U represents the effective back-electromotive force (EMF); i denotes the circuit current; [L.sub.w] and [R.sub.w] are the equivalent inductance and resistance of the three-phase windings, respectively; [L.sub.bc] denotes the inductance of the boost converter's inductor; [U.sub.c] represents the terminal voltage

The output of the PI controller ([I.sub.smq(n)]) required to maintain constant AC terminal voltage

If the terminal voltage
