Modularized bidirectional step-up DC-DCD converter with predictive battery equalization method

Battery systems that require higher voltage outputs use to face the problem of State of Charge (SOC) equalization of the cells, which causes premature deterioration of the batteries. This paper proposes a modularized system based on a bidirectional boost converter and an intelligent control of charge and discharge of the battery system based on predictive control system. The main objective of this system is to maintain all cells or banks in an equal charge in order to improve their health and total energy capacity available to use. This system can be used as an alternative method to the common series connected batteries systems.
