The rated capacity of the Lithium-ion battery is 1.1 Ah. The charging strategy is “C1 (Q1)-C2 (80%)-1C”, where C1 and C2 are the first and second constant current steps, respectively, and Q1 is the state of charge when the current is switched. The constant current phase of the battery continues until the SOC reached 80%.
Even though, as the operating conditions of commercial lithium-ion batteries drastic changes in practical application, the batteries' resistance value can be between 10 m Ω and 1 Ω, i.e., within a rate of 100, making it difficult to achieve a parameter-independent voltage regulation. 3.

At present, the assessment of the SOH of Lithium-ion batteries is mainly divided into model based methods and data-driven based methods. Model based methods include: electrochemical model (EM) , , and equivalent circuit model (ECM), etc. , .
Lithium-ion batteries are becoming increasingly popular for energy storage in various hybrid energy systems, hybrid ac/dc, micro-grid, e-mobility applications. However, due to the wide battery impedance range, the performance of lithium-ion battery interfacing dc-dc converter is affected, results in complicated task for design of this regulation.
However, due to its nonlinear characteristic, the inner impedance of lithium-ion batteries, which depends on the battery state-of-charge (SoC), state-of-health (SoH), the temperature, the current and the previous history [ 5 ], usually vary in wide range.
