Abstract: The lithium ion battery emerged in the commercial market in 1991 and introduced new technology advantages over its energy storage predecessors. Lightweight, high energy density and low maintenance are among the key advantages that it offers. Ten years after its debut, lithium ion secondary battery makes its first orbit around the Earth. The High Power devices, such as Weapon Locating Radar’s, satellite communication system, and other defense applications. Most of these devices are powered by lithium batteries. These Lithium batteries will need to be charged anywhere between 1-7 days, on the regular basis. Seeing the opportunity, many manufactures have rushed to the scene with all type of chargers specifically designed for single-cell and multi-cell Lithium batteries. This paper presents the design and implementation of a controller based lithium-ion battery charging system with higher reliability with different sensor’s and protection circuits. Since 30-60% of the capacity of lithium ion cells may be restored during the taper charge, this charger has a distinct benefit of fully charging lithium ion batteries by restoring all of the available capacity to all of its cells. To obtain the optimal charging performance for the lithium-ion battery charger, a boost converter & buck converter is used in the proposed system. Using this topology, the performance of the proposed system can be raised. Simulation and experimental results validate the effectiveness of the proposed charging system.
