Human beings in 21 century mainly depends on machines that need energy to give required output & rechargeable batteries are main source of energy in many cases as it is used widely, but is required to adapt new technology for recharging batteries so that overcharging of battery don’t occur which leads to battery damage. Research centre for computational intelligence made progress in making battery charger compitable with future need by developing partially DSP based fuzzy logic controller for a battery charger so that overcharging problem is solved. This project is an approach towards the development of a device which can control the charging of battery to specific level efficiently without damaging it in any way. We will be discussing over the various tools of MATLAB like FUZZY LOGIC and DSP PROCESSOR which are available to device this instrument. We will go for in-depth discussion regarding theory and working of each tool in detail. We will have a brief description on the scope of these controllers. We will be evaluating the scope and impact of these tools to control the overcharging automatically. Beside all these we will throw some light on how we can evaluate the safety speed of charging for different battery. After this we will show the various salient features of our system and discuss its compatibility. An analysis of the various challenges which this device may face with its suggested solutions will be discussed. At last before coming to the conclusion we will have an insight to the future remarks and development of this device as per future needs. The conclusions will reveal the impact of this device globally and will show its real merit. The aim of our project is to develop a DSP based fuzzy logic controller which will charge the battery to its optimum level and also preventing it from overcharging, by continuously monitoring its current and voltage. Experimental results have shown that DSP+FUZZY was to correctly adapt its charging according to the maximum level of charging. The learning process of charging battery using DSP based fuzzy logic controller is still on, encouraging for the computation of project.
