Abstract
According to the problems of lithium battery, which has abroad application prospects, in the process of charging, by using of the constant current to constant voltage charging method, this paper designs a smart fast charging system based on the ATMEGA128 microcontroller and LTC4100 battery charging controller. The core modules of the MCU control and charging circuit are mainly designed to achieve the efficient and fast charging. During the process of charging, the system can automatically track the acceptable charging current of lithium battery, and monitor the charging current, voltage and temperature to realize the intelligent and precise control for the whole charging process, which can guarantee that lithium battery is neither over-charge nor less-charge. As overcharging of lithium batteries affect the efficiency and life of the battery, our project aims to overcome this problem by introducing 3 mode charger and this charger will allow the user to know about the charging periods and also turnoff the supply input to the device. Along with this operation the charger is able to perform conventional mode of charging with the charging circuits which can overcome current or voltage fluctuations. Another mode is to step up or step down voltage to charge various other devices than mobile battery. In order to achieve this goal several tasks need to be performed.
