MPPT solar charge controller for lithium ion battery with boost converter topology

In this study, solar charge controller MPPT which has amplifier topology has been developed and it is aimed to charge electric batteries and load transportation vehicles by taking support from solar energy in travel and to take longer distance. In this thesis, Lithium Ion (Li-Ion) battery charging characteristics are investigated. At the same time, electrical models of solar panels were examined and Maximum Power Point Tracking (MPPT) algorithms were studied on. Some calculations have been made on Direct Current (DC) - Direct Current (DC) transformer topologies of the electricity and it've been provided that Li-Ion batteries and lead acid batteries can be charged safely and efficiently by using solar panels. A solar charge controller has been designed for making MPPT for charging of Li-Ion batteries and lead-acid batteries with energy that is generated from solar. And this solar charge controller has also a topology converter to charge a high-voltage battery pack from a single-piece solar panel with a low-voltage value converter. In the design steps, firstly, after the system requirements and project objectives were determined, theoretical calculations were made within the framework of certain assumptions. Among MPPT algorithms, as an effective method that can be used, classical change visualization algorithm have been used instead of a multi-point change visual algorithm. The switching losses in power electronics circuits have been examined and the design have been designed with considering efficiency in the foreground. This study have been also evaluated as a preliminary study to support battery charging systems for future solar powered electric vehicles.
