SIEVE: A Smart Infrastructure for an Electric Vehicle Ecosystem

Researchers at IIT Delhi are working on a project to design an end to end sustainable solution for electric vehicles.

The SIEVE (Smart Infrastructure for an Electric Vehicle Ecosystem) project is a multidisciplinary project spread across four departments: Computer Science and Engineering, Electrical Engineering, Mechanical Engineering, and Chemical Engineering.

Currently there is a strong push for the adoption and indigenization of electric vehicle technology. Given that an EV requires at least 60-100 W of power (equivalent to 20 homes) while fast-charging, the process of charging has to be regulated. This requires novel techniques that regulate the charging power, and optimally place charging stations along with ensuring the security of CAN bus protocols.

“The aim is to design a full end-to-end solution for electric vehicles. We are working on designing smart, scalable, and secure protocols for charging and operating EVs. This will require innovations in the IoT hardware used in EVs, and a secure charging infrastructure,” says Prof. Smruti Sarangi from the Computer Science and Engineering department, who is the PI of the project.

There are four distinct components in this project: design of Redox flow batteries, electric vehicle, charging technologies, IoT based communication and management and self driving algorithms.

Prof. Anil Verma from Chemical Engineering is leading the effort on designing vanadium-oxide Redox flow batteries. Such batteries have inherent advantages in terms of the ease of replacing electrolytes, and energy/power tunability, and complete discharge without damage. In general such batteries are tailored towards large energy storage systems; adapting them to small and medium scale setups is a challenge.

The second part of the project on EV charging systems is being led by Prof. B. K. Panigrahi. His research is focused on novel charging technologies particularly chargers that leverage renewable sources of energy. Along with Dr. Sumit Pramanick, Prof. Panigrahi's team is working on creating India's largest lab that is focused on EV technologies. The aim is to design fast charging technologies, and novel methods for data collection in EVs.

Prof. Sunil Jha from Mechanical Engineering is working on creating novel self-driving algorithms for Indian roads. This includes incorporating latest state of the art LIDAR, machine learning, and computer vision technologies into EVs.
