Cataloged from PDF version of thesis. Includes bibliographical references (pages 56-60). Draining batteries at a high speed is one of the modern problems we face due to the electrical devices’ power consumption rate. Moreover, as we need to use them frequently, charging them quickly is the necessity of the era where we cannot pass a single moment without wireless electrical devices. To fulfill the need, fast charging concept came to an existence where we inject a larger amount of current or voltage in a controlled way. In view of the properties of the lithium-ion battery, it is used widely for fast charging. Pulse method, CC-CV method, Multistage constant current (MCC) etc. are some of the fast-charging methods. Though CC CV method is used widely, it has some drawbacks like heating the battery. So, to overcome the drawbacks we use the pulse method where the temperature does not increase much but the speed of the charging increases. In the pulse method, we are using two algorithms simultaneously, optimal frequency search and optimal duty cycle search. We are also searching for ambient temperature to fast charge as temperature may hamper fast charging performance. Saffat Newaz Sadmani Md. Tanvir Hossain Md.
