Our history - Our values

IES has been at the cutting edge of the market for advanced electric vehicle charging solutions since 1992. Gambling on innovation is behind this success, combined with extensive expertise in converting high-frequency power and a strong international focus.

IES has always been there at the major stages in the electric vehicle industry. The first to design and manufacture an on-board charger for forklifts and lifting cradles, first to equip a mass-produced light electric vehicle, involved in developing the Combo charging protocol for major German manufacturers, delivering mobile solutions for the development of many vehicles in the marketplace, taking up the competition challenge by equipping the FIA Formula-e World Championship, IES has been a part of the major events that have forged the market.

This innovation track record has spurred IES to expand internationally into Europe, America and now China with an equal joint venture with the Wanma Group.

The ability to innovate and understand fully all charging technologies has been boosted by a car-standard industrial organisation. Controlling the choice and qualification of all components and hot testing all its chargers demonstrates IES’ primary focus on product quality and reliability. 

IES designs and provides the most advanced, versatile and universal solutions on the market, regardless of your needs. And the IES technology opens up other groundbreaking prospects, be it to lift the brakes on rolling out a huge charging infrastructure in our towns, work towards energy optimisation in buildings and at home or simply making user and operator experiences easier.

In 2018, the Nexans industrial group joined the capital, thereby ensuring the long-term development of IES to remain a dominant electromobility player on the world stage.


Jean-Michel Cornille, CEO

“The availability of a well-structured charging network is clearly dictating the move by our fellow citizens towards electric vehicles.

New forms of mobility are going to make their appearance, like car-sharing and zero emission public transport, to combat the effects of pollution and deal with the increasingly congested and restricted access to our towns. We have developed unique streamlined and competitive solutions, thereby making it so much easier to roll out these charging networks for both private and shared vehicles. We are convinced that these compact, universal and cost-saving solutions will be key in helping to roll out charging solutions en masse in public and commercial spaces that are for flexible use by all concerned.

Potential users see power reserves and vehicle cost as other obstacles. Advances in battery technologies, pulling density upwards and costs downwards, are making electric vehicles more affordable and extending their power reserves. For example, new generations of electric vehicles are being promoted with ranges of 500 to 600 km without charging. We believe that electric vehicles are deservedly taking their place in the French energy mix, showing the enthusiasm of manufacturers and French legislation that encourages the sector.”
