Four major carmakers have decided to coordinate development of a technical standard for the recharging of electric-vehicle batteries in Europe.
The group, which consists of Renault and its alliance partner Nissan, PSA/Peugeot-Citroen and Mitsubishi Motors, will develop a technical reference based on the "EV Ready" standard originally developed by Renault and Schneider Electric, a French energy management specialist.
The companies said in a press release that they want to achieve interoperability between charging systems across Europe.
EV Ready was first launched in June 2010. More than 60 European companies, including energy providers, network operators, suppliers and installers of charging stations, are working to develop and adopt EV Ready products.
Separately, Schneider Electric said it has become the first manufacturer worldwide to obtain ZE Ready certification from Renault for its EVlink electric vehicle charging infrastructure range.
ZE Ready is a compatibility testing protocol that guarantees that internationally accepted standards will be implemented consistently among EVs and the charging infrastructure. It aims to control the entire charging chain, from charging station design and installation to installer training, preliminary audits, any necessary compliance work and consulting.
Schneider Electric said Renault's ZE protocol will help reduce the number of tests that need to be carried out. It will also guarantee customers that all systems work, Schneider added.
Said Vincent Brunel, Schneider's electric vehicle business development director: "ZE Ready represents a fundamental step in establishing a protocol that will be shared by all carmakers and electrical equipment manufacturers."
