Abstract

While the use and production of Electric Vehicles becomes more prevalent, it is also important to make this economical and ensure the reduction of a carbon footprint. Second-life batteries can satisfy both problems as batteries can be used in a second-life application for lower power purposes such as supplementing the grid so the infrastructure needed to charge the expanding fleet of Electric Vehicles can be easily supplied. This thesis goes through the process of Active Cell Balancing which will produce equal capacities, or similar batteries, that can be more efficiently used in these and other types of second-life applications. The process is expanded through series connection of the converters and modules of batteries so the process can be used for up to 96 Nissan Cells at a time. This project at Utah State University will also entail the removal and replacement of these Nissan battery cells while running to ensure quick but smooth balancing of hundreds of batteries.
