Low Cost and Flexible Battery Framework for Micro-grid Applications

A low cost flexible battery framework for micro-grid application is presented in this paper. The battery structure is based on a hierarchical and modular approach to easily adapt the battery design to different voltage and capacity requirements. This feature makes the battery configurable and usable in different kind of micro-grids reducing design complexity and cost. The framework presented here is used to design a battery that satisfy the needs of a micro-grid equipped with a micro electric vehicle charging station. The battery implementation was verified with a preliminary test campaign that confirms the successful usability of the battery in this environment.
