The main purpose of this study, the Design and Realization of a Wireless Lithium-ion Battery Monitoring Management System, is accomplished. This system is composed of feedback circuits, a microcontroller, pulse-width modulated (PWM) boost circuits, a boost and buck converter, a wireless monitoring system and a Boston Sonata 4400. The battery can be quickly and without injury the battery life by using the constant current to constant voltage charging method. The LED light can use different luminance values by changing the PWM signal to control in discharge mode. The system uses a microcontroller by ATmega328. By the feedback circuits, the microcontroller can automatically regulate the PWM signal to change the charging and discharging rates of the boost and buck converter. Finally, the battery can be managed via a wireless monitoring system for remote monitoring.
