Abstract
This paper presents a method to improve Li-ion battery charging speed for portable electronic devices maintaining stable operating temperature. The proposed method uses multiple chargers which consist of a master module and slave modules designed with single wire communication signal for parallel current path in order to simplify the additional hardware needs. A single wire communication signal control between a master module and slave modules makes the number of pins of parts lowered and the required area small, furthermore leading to lower cost. Therefore the proposed charging method can be practically used for implementing battery charging modules requiring high speed Li-ion battery charging.
