After announcing its ambitious offer of electric vehicles for the coming years, Renault<\/strong> is clear that without a charging infrastructure and advanced technologies in this regard it will be very difficult to lead electric mobility on a global scale.<\/p>\n\n\n\n

The French brand revealed details of V2G<\/strong>, or vehicle-to-grid, a two-way sharing technology that will soon allow vehicles to return part of the electricity stored in batteries to optimize grid operation and compensate for the intermittent nature of renewable energies.<\/p>\n\n\n\n

The innovation is led by the French Commissariat \u00e0 l’Energie Atomique et des Energies Alternatives (CEA), which, together with Renault<\/strong>, is working hard on future generations of these V2G technologies to be implemented by the end of this decade.<\/p>\n\n\n\n

Along these lines, the CEA <\/strong>and Renault Group<\/strong> have jointly developed a new electronic power converter architecture integrated directly into the car’s charger.<\/p>\n\n\n\n

Technological Scope<\/strong><\/h2>\n\n\n\n

After nearly three years of research and having been the subject of 11 joint patents filed, this power converter will reduce energy losses by 30%<\/strong>, improve vehicle charging time and ensure battery durability.<\/p>\n\n\n\n

According to a report by Inside EVS<\/strong>, the device will be essentially bi-directional by storing energy coming from the power grid.<\/p>\n\n\n\n

The CEA and Renault Group R&D teams have combined their expertise in on-board power electronics, in particular in so-called “Grand Gap” semiconductor materials, either gallium nitride (GaN) or silicon carbide (SiC).<\/strong><\/p>\n\n\n\n

The result is a new architecture based on “Grand Gap<\/strong>” components that reduces energy losses during conversion by 30% and reduces heating by the same amount<\/strong>, facilitating the cooling of the conversion system.<\/p>\n\n\n\n

Thanks to the use of ferrite materials, dedicated to high frequency, and an injection molding process called “Power Injection Molding”, the converter is now more compact.<\/p>\n\n\n\n

This new architecture offers a charging capacity of up to 22 kW in three-phase mode, allowing the vehicle to be charged faster and ensuring the durability of the battery.<\/p>\n\n\n\n

Great Results<\/strong><\/h2>\n\n\n\n

Jean-Fran\u00e7ois Salessy<\/strong>, Renault Group Advanced Engineering Director, explained that this project alongside CEA <\/strong>exceeded expectations by confirming the ability to achieve the expected results in terms of efficiency and compactness.<\/p>\n\n\n\n

“This opens up high prospects for power electronics, which is a real challenge for the electric vehicle when it comes to making the most of the batteries’ capabilities,” <\/strong>added the executive.<\/p>\n\n\n\n

Salessy says that with bi-directional recharging, the vehicle is put at the service of the electrical grid and allows the end consumer to reduce his or her energy costs.<\/p>\n","protected":false},"excerpt":{"rendered":"
