Evaluation of the combination of an electric vehicle and a repurposed used electric vehicle battery for a residential energy storage system

Abstract

Electric vehicles spread exponentially as they are the vehicles of the future. Most of the time, they are parked at home. This parked car can be useful by using its battery as energy storage system for the house. Stationary home energy storage systems are currently developed using repurposed end-of-life electric vehicle batteries as well. In this thesis a model will be developed to evaluate the economical and environmental benefits from the combined use of an electric vehicle battery and a stationary home energy storage battery. This model was used to simulate optimal battery storage management for a number of residential use scenarios. It was found that significant economical as well as some greenhouse gas emission savings can be achieved depending on the use case.
