HAVEN project to test potential of EV batteries to save energy in the home

The partnership between Good Energy, Honda, Upside Energy and Salford University will use the university’s unique climate controlled ‘Energy House’.

Good Energy is partnering with Honda, Upside Energy and Salford University on a new vehicle-to-grid (V2G)—and ‘vehicle-to-home’—project which will test how electric vehicle batteries and other battery storage units can impact home efficiency.

Funded by Innovate UK, the new project will take advantage of Salford University’s unique testing facility, Energy House, which is the only full-scale building in an environmental chamber in Europe. Named ‘HAVEN’, it will explore the use of electric vehicle (EV) batteries to provide flexibility to the energy system within the context of other systems in the home, such as batteries attached to solar panel arrays, heating and hot water systems.

V2G technologies are a way of tapping into the storage capacity of electric vehicles. Battery storage is vital to the continued growth of renewable energy in the UK, as it helps solve renewable sources’ reliability issue — the changeability of the weather.

By conducting tests within the controlled environment of the Energy House and with the use of a charging point from Honda which is the first of its kind in the UK, the project will investigate different configurations to build a suite of models for the value of EV and other battery storage systems within an integrated home energy storage system.

Upside Energy will be managing the project, and its cloud based software will provide the platform for the testing conducted.

Juliet Davenport, CEO and Founder of Good Energy, said: “EVs, battery storage, V2G and now vehicle-to-home are all technologies that will be part of a decentralised energy system of the future. This project uses Salford University’s Energy House, which means that we can truly see the impact for people’s homes, and their lives. I’m really excited to see what the findings are and how we can use to them to help our customers get to a cleaner, greener world.  ”

Will Swan, professor of building energy performance at the University of Salford, said: “Energy House can be subjected to simulated climates – sun, wind, snow and rain and is equipped with 300 sensors on windows, doors, walls and appliances.

“That makes it the perfect living laboratory to test what V2G can do because we can measure the gamut of scenarios in controlled conditions.”

Neil Jones, programme manager at Upside Energy said: “We are delighted to be working with the University of Salford, Honda and Good Energy in this project to learn what opportunities V2G offers in supporting the uptake of renewable energy and also providing energy security.

"These tests at a single house level (Energy House) will help us establish a baseline of data which could be scaled up to hundreds if not thousands of homes and vehicles and start to identify what services can be offered to householders and the grid in the future.”
