Lithium-ion battery charger for high energy application

Abstract

This paper describes the design of microcontroller-based battery charger to charge lithium-ion battery pack with the charging method, balancing technique, charging control algorithm, battery protection, battery management unit and implementation of the battery charger are discussed concisely. Advantages, disadvantages and problems arise are also discussed. In fact, an excellent battery charger offers very fast charge time, full capacity and balanced battery cells, low operating temperature and highly efficient and reliable.
