The coupling of solar cells and Li-ion batteries is an efficient method energy storage, but power suffers from the disadvantages randomness, intermittency fluctuation, which cause low conversion efficiency into electric energy. In this paper, a circuit model for system with PV charge controller battery presented in MATLAB/Simulink environment. A new three-stage charging strategy proposed to explore changing performance battery, comprising constant-current charging, maximum point tracker (MPPT) constant-voltage stages, among MPPT stage can achieve fastest (MPP) capture and, therefore, improve efficiency. Furthermore, lifetime through scheme. simulation results indicate that improvement tracking 99.9%, average reach 96.25%, higher than commercial chargers. This work efficiently matches enhance storages, provides optimization idea hybrid PV/Li-ion systems.
