Design and simulation of reused electric vehicle battery systems for home energy storage and vehicle charging

At the end of vehicle life, electric vehicle batteries are still expected to contain around 70% of their original capacity. Although they are not energy dense enough for a vehicle, they could be repurposed for stationary energy storage where size and weight are less constrained. This provides a more sustainable end of life path, as the batteries produce additional value before eventually being recycled. This thesis will investigate several concepts for an energy storage system using batteries from existing electric vehicles. Using computer based models of the concept designs, the thermal and electrical performance of the systems will be tested for various loading conditions such as back-up power, load shifting, and vehicle charging. Particular emphasis will be given to reducing cost by reusing the existing thermal management systems of the electric vehicle batteries.M.S
