Abstract: In this paper, a linear model for describing the Li‐ion battery charging response is developed. Then a Phase‐Locked Battery Charger (PLBC) mathematical model is built, and its s‐domain transfer function is also derived. The stable, safe and fast charging conditions of the PLBC are discussed and many criteria are proposed. After that, a complete design procedure is presented for designing a fast and safe PLBC. Finally, a test example of the PLBC is designed and implemented for a 700 mAh Li‐ion battery in order to assess the performance of the presented Li‐ion battery model, PLBC mathematical model and design criteria. Experiments show that the computer simulation is close to the actual measurement. This means that the presented models of the Li‐ion battery and the PLBS are correct and can capture major electrical characteristics. Experiments also show that a stable, fast and non‐overcharging PLBC is successfully implemented as we wanted. This indicates that the presented PLBC design procedure is valid and can really help engineers design a fast and safe battery charging system.
