The utilization of retired electric vehicle batteries for stationary energy storage is a reliable solution to integrate renewable energy sources with the grid system. The study found that second life batteries showed promising technical performance and can be considered a viable solution for the integration of renewable energy sources with the grid system.
Integration of large renewable energy sources (RESs) to the grid is aimed to solve the problem of shortage of power with the production of surplus energy and satisfy the increasing demand. However, the intermittent nature of RESs is challenging to integrate with the grid system. Therefore, the utilization of storage batteries, particularly the re-use of retired electric vehicle batteries for stationary application is therefore a reliable solution to mitigate this problem. In order to evaluate the performance of second life batteries in stationary application, first, the optimal sizing of storage batteries and the cycling profile definitions are performed. Based on the defined cycling current profiles, the second life aging of retired battery cells is conducted at the cell and module level aspects. From the result of the study, it is found that the technical performance of second life batteries is promising and can be regarded as a viable solution for the integration of RESs with the grid system.
