A Fast Charging System based on Charging Current Dynamic Adjustment Method

摘要

This paper presents a fast charging system for smart devices. A novel scheme of dynamically adjusted charging current based on voltage-current dual-loop control is employed to fully utilize the power of the adaptor and maximize the charging speed. Simulation and experiment show that at least 12% more battery can be charged by the proposed method within 5 minutes of fast charging, compared to the conventional fast charging scheme.
