The VIGIL project
Vehicle-to-grid technology (V2G) represents a significant step in the UK’s transition to low-carbon transport and a smart energy system. The VIGIL project, funded by the Office for Low Emission Vehicles and the Department for Business Energy and Industrial Strategy in partnership with Innovate UK, aimed to return energy to the power grid when electric vehicles (EV) are parked and plugged for charging. This allows for better exploitation of renewable sources and lowers the cost of ownership, leading to new business opportunities and clear advantages for both EV users and energy consumers.
The project team included members of Aston University’s EBRI Institute, as well as the three companies bringing this system to market: Nortech Management Ltd, Grid Edge Ltd, ByteSnap Design Ltd.
VIGIL is an off-vehicle platform that supports multiple V2G charge posts.
Installed on two sites at Aston university, it is the UK’s first comprehensive communication and control platform for managing V2G systems and electrical networks.
The project successfully demonstrated the platform’s capability to monitor and control car charging/discharging and manage building energy dispatch in real time, while considering building and car user requirements as well as electrical network constraints.
More information about the VIGIL platform and the project outcomes can be found here.

Best Paper, IET International Conference RPG 2019
The Aston University team researched EV battery lifetime performance and evaluated harmonics data during V2G operation. Using real-world data from the monitoring systems, the team investigated V2G impacts on battery degradation and published their research outcome at IET International Conference on Renewable Power Generation 2019. The paper was awarded Conference Best Paper by the conference committee.
