RESEARCH CONTRIBUTIONS

Lyapunov-Based Adaptive State of Charge and State of Health Estimation for Lithium-Ion Batteries

This paper presents an adaptive state of charge (SOC) and state of health (SOH) estimation technique for lithium-ion batteries. The adaptive strategy estimates online parameters of the battery model using a Lyapunov-based adaptation law. Therefore, the adaptive observer stability is guaranteed by Lyapunov's direct method. Since no a priori knowledge of battery parameters is required, accurate estimation is still achieved, although parameters change due to aging or other factors. Unlike other estimation strategies, only battery terminal voltage and current measurements are required. Simulation and experimental results shown in Fig.1 and Fig.2 highlight the high SOC and SOH accuracy estimation of the proposed technique.

Fig. 1. Experimental results for discharge mode: (a) and (b) battery's voltage Formula; (c) battery's impedance Formula; (d) battery's current Formula; (e) voltage estimation error Formula; and (f) OCV estimate Formula and SOC. The battery voltage tracking and error convergence to zero for both equilibrium and discharging states is shown in Fig. 1(b) and (e). The advantage behind the use of the adaptive observer is clearly shown by very good tracking performance and negligible amplitude, where the voltage error is kept in, i.e., 0.1%, within sensors' resolution. As the battery discharges, OCV decreases [Fig. 1(f)] and battery impedance increases [Fig. 4(c)].
