Toyota sees dynamic wireless charging allowing for smaller batteries

After extensive testing with the dynamic wireless charging feature installed on the Toyota RAV4 Prime, Israel-based Electreon is working with Toyota and leading supplier Denso to develop a dynamic wireless charging system for vehicles. Toyota electric.

Strategic deal, delivered less than a month after teasing Future wireless charging in Tesla carscould lead to a joint development agreement to create an aftermarket wireless kit for current electric vehicle models such as Toyota RAV4 Primetechnology integration into new vehicles and a joint pilot project in Japan, the US or the EU, according to the companies.

That includes what has been described as a “collaboration to shape standardization.” wireless electric car charger.”

The companies have not clarified what that means. The Society of Automotive Engineers (SAE) 2020 announced for the first time The global standard for wireless electric vehicle charging up to 11 kW, and Electreon is already part of the process behind these standards.

“Toyota hopes that dynamic wireless charging technology will serve as one of the solutions to the problems associated with electric vehicles,” the joint statement said, noting that a technology review recently included a demonstration of the RAV4 Prime wireless charging. road.

That could help reduce the size of batteries needed in EVs or extend their driving range, the companies explain — and it also has the potential to offload the grid and help incorporate renewable energy sources. easier. Those things were outlined in more detail in a White paper from Electreon released last year.

While today’s leading supplier of factory wireless charging technology, WiTricity, is focusing on static wireless charging—when the vehicle is parked—Electreon seeks to provide flexible (when the vehicle is in) operational solutions. moving) as well as static.

Toyota has shown an interest in wireless charging technology for more than a decade and it has become a a stakeholder in WiTricity back to 2011.

That could mean higher prices for integration in electric vehicles, while projects incorporating dynamic charging have been very small so far. They involve placing magnets on the road surface, as well as sources of energy far beyond what the road lighting system requires.

Projects in which vehicles frequently cycle around the same route are the best options for technology—such as airport access and terminal loops or central ride-hailing areas. It has been tested with short route bus service in Tel Aviv, a truck orientation road toll project in Swedenand a short partial electrification project of the German Autobahn.

Besides, the convenience of static wireless charging can support EV adoption. According to the results from authorized studies from WiTricity, technology can sell more electric carsand EV shoppers are more interested in seeing wireless charging as an option rather than self-driving.
