Efficient and Interoperable EV Charging: Building an ISO15118-Compliant Charger using EVerest Software Stack

The ISO15118 protocol has emerged as a promising standard for communication between electric vehicles (EVs) and charging infrastructure. Building an ISO15118-compliant charger, however, requires specialized software stacks and hardware, which can be costly and time-consuming. The thesis presents a design and implementation of an ISO15118-compliant charger using the EVerest software stack and off-the-shelf hardware, and tests its performance in different scenarios. The charger is tested using different cars and considering different communication protocols. The results demonstrate the successful implementation of an ISO15118-compliant charger using the EVerest software stack, and the charger is found to perform well under different charging modalities. The thesis also provides an overview of some other available software stacks that aid in building ISO15118-compliant chargers. This conceptual comparison highlights the strengths and weaknesses of each approach and provides insights into the selection of suitable software stacks for different use cases. Overall, this thesis demonstrates the feasibility of building an ISO15118- compliant charger using the EVerest software stack and off-the-shelf hardware. The results of this thesis contribute to the development of efficient, reliable, and interoperable EV charging infrastructure, which is critical for the widespread adoption of EVs.The results of this thesis can inform the development of future EV charging systems and contribute to the ongoing efforts to reduce greenhouse gas emissions and promote sustainable transportation.
