About IES Synergy

We want to take electric vehicles further by making access to energy safer, more reliable and more efficient. Our vision is reflected in every innovation: modularity, interoperability and energy efficiency. By combining technology, responsibility and sovereignty, we aim to turn energy constraints into a lasting competitive advantage for every player in the mobility sector.

Founded in Montpellier in 1992, IES Synergy is a leading French player in electric vehicle charging. Drawing on pioneering expertise in power conversion, the company designs and manufactures high-performance, reliable and interoperable KEYWATT® charging stations and chargers in France. What sets us apart is our ability to combine technical performance, industrial sovereignty and operational agility.

Operating in more than 50 countries and serving over 300 customers, our long-lasting solutions are designed to meet every use case: local and regional authorities, bus and truck depots, public car parks such as shopping centres and hotels, private company car parks, and industrial manufacturers of electric equipment requiring onboard chargers.

Thanks to complete control of the technology chain and a modular approach, we ensure quality, ease of operation and a seamless, sustainable and competitive experience for every mobility stakeholder.

Since its creation in Montpellier in 1992, IES Synergy has continuously innovated. From its first onboard charger to KEYWATT® fast-charging stations, as well as ultra-fast and bidirectional solutions, our history is that of an electromobility pioneer. As a partner of the CEA and Renault and a beneficiary of the France Relance programme, we have built a strong track record combining industrial rigour with continuous innovation. Today, our products are deployed in more than 50 countries and embody French expertise dedicated to sustainable mobility.

At the heart of IES, our R&D teams bring together engineers and designers in France who share the same ambition: to make charging simpler, faster and more sustainable. From power electronics to embedded software, we control the entire value chain, turning every idea into a reliable, industrially scalable and upgradeable product.
Every day, we prototype, test and optimise our solutions to raise market standards in energy performance, safety, cybersecurity, availability and full interoperability. Our eco-design approach reduces the carbon footprint from the design stage onwards, while optimising operating costs for our customers.

IES Synergy offers a comprehensive range of charging solutions designed to the highest standards: fast-charging stations for on-street locations, car parks and motorway hubs; onboard chargers for passenger and industrial vehicles; and innovative services such as Plug & Charge and Vehicle-to-Grid (V2G). What sets us apart is the combination of technical performance, industrial sovereignty and operational agility. Thanks to our modular architecture and unified KEYWATT® software suite, we provide a seamless, reliable charging experience that is interoperable with all standards. Our solutions adapt to every application, from individual users to large fleets, while optimising total cost of ownership.
