A cost-effective battery management and monitoring strategy for micro-grids in India

Energy buffer cost is a key factor in rural electrification, electric vehicles, mobile devices, etc. Increasingly, micro-grids and off-grid home electric systems have become popular in the developing world to help meet energy demands. These systems help provide electric power to customers when the main power utility is unable to do so, such as in rural communities or newly developed townships. However, a major limitation of micro-grid expansion is the system cost, with the energy buffer accounting for perhaps 50% of the cost. This work addresses such costs by addressing battery longevity through the creation of a cost-effective and easy to use battery monitor that helps off-grid system operators increase the lifetime of the battery system. This work also explores methods of extracting battery health information from existing off-grid batteries to help determine remaining battery life.
