This project introduces an innovative approach for reusing and extending the lifespan of second-life Li-ion batteries. It is developed in collaboration with Reefilla, a startup founded in Turin in 2021 and currently incubated in I3P at Politecnico di Torino. Starting from the VDA3xx battery module a new architecture and packaging approach have been designed enhancing flexibility and support multiple applications. These characteristics can be achieved by leveraging a brand new swappability features and embedding a smart BMS to trace over the module lifetime important value such as SOH. The concept design has been conceived to simplify the manufacturing process employing high pressure die casting that uses recycled aluminum.
