Plans to install rapid electric car charging at over 50 locations on the motorway network are being taken forward by the National Grid.
It says 90% of people using motorways in England and Wales could be within 50 miles of a 350kW rapid charger, which can recharge a vehicle battery in five to 15 minutes.
Up to 50 charging points placed at each location should, it adds, avoid queues at peak times. It estimates that the necessary investment in grid infrastructure will be between £500M and £1Bn.
National Grid says that the roll out of charging infrastructure should be “structured and co-ordinated” rather than connecting one customer at a time.
“Range anxiety is consistently given as a major reason for not buying an electric vehicle and we’ve put forward a solution that addresses this,” says the organisation’s electric vehicles project director Graeme Cooper.
“If you overlay the motorway network over the electricity transmission network, there is a synergy,” he added, pointing out that the electricity transmission network runs close to the motorway network.
“We want to show that infrastructure needn’t be a barrier to electric vehicle growth and a structured and co-ordinated roll out of rapid chargers is achievable.”
Highways England has been approached for comment.
