A UK company has launched an interoperable electric vehicle (EV) charging network system in four UK cities.
From 18 February, Chargemaster extended its system to cover public charging points in Cambridge and the London borough of Hillingdon, following its January launch in Oxford and Milton Keynes.
Previously, EV drivers who registered in one town or city could not charge their cars in another as the systems were incompatible.
“There is currently no uniformity between them. This is one of the main drivers of range anxiety,” Chargemaster told ENDS.
“We are working actively with the Plugged in Places programme to promote interoperability across the UK,” the company said.
Chargemaster’s system allows EV drivers to charge their cars in any of the four regions.
Councils can measure the amount of electricity being used, forecast future usage and monitor and identify peak-usage times.
Chargemaster is working with Arup, the UK engineering consultancy, and Scottish and Southern Energy, to deliver the scheme.
Meanwhile, the International Organisation for Standardisation has signed a memorandum of understanding with the International Electrotechnical Commission.
As various EVs are launched this year, the memorandum recognises the importance of jointly agreeing standards for new vehicle types between car makers and the electricity supply industry.
