Sharing home charging points could bridge infrastructure shortfall

Just 4% of home chargers would need to be shared publicly to bridge a public infrastructure gap for electric vehicles (EVs), according to new estimates by Dodona Analytics.

The "Will the EV charge point roll-out put the brakes on cleaner transport?" report from the data and analytics company suggests that without sharing home charging points with neighbours living in flats or accommodation where they can’t have their own charger, there will be a shortfall or ‘charger chasm’ of over 250,000 chargers.

While there are already 35,000 public chargers in the UK, this is a fraction of the number of home chargers – estimated to be at least 300,000.

A growing number of companies facilitate EV charge point sharing via apps.

The app connects the 'host' or charger owner with motorists who would like to rent their charger and will handle the 'matchmaking', bookings and payments. 

Co Charger connects communities to share chargers within neighbourhoods while other apps also offer 'destination charging' as an alternative to public and motorway charging on long journeys.

In their white paper Will the EV charge point roll-out put the brakes on cleaner transport? Dodona Analytics has created a model which shows the relationship between projected supply and demand for public EV charge points between 2021 and 2030.

The projected demand for EV charge points is based on the assumption that the number of EVs in the UK will continue to grow exponentially until it reaches nine million in 2030.

However, it argues that installation of new charging points is not keeping pace with the EV market.

In the last three years 7,469 new public charge points were installed each year, according to data from Zap-Map.

Dodona Analytics modelled the scenario where there were 10,000 new charge points every year, reaching 133,642 in 2030.

Policy Exchange, the UK's leading Think Tank in its report Charging Up predicted that the UK will need public 400,000 chargers by 2030 in addition to home chargers.

Stefan Furlan, Dodona Analytics chief executive, says: “Our research shows there is a wide gap between the future demand for and the current availability of charge points.”

Furlan recommends a data driven approach to site selection and infrastructure deployment, the sharing of home and workplace chargers and cross-industry collaboration.

Joel Teague, Co Charger chief executive, said: “The UK's public charger building scheme is ambitious, well-organised and well-funded, but as this paper shows, further access to chargers is needed to help motorists in flats and terraces make the transition.

“Charge point sharing is a quick, cheap, and self-scaling solution – as EV ownership rises, more home charge points will become available, which can then be shared with neighbours, enabling them to enjoy the benefits of owning an EV and a cleaner, greener neighbourhood.”
