The main goal of the project is to increase the range of electric vehicles without relying on traditional charging infrastructure, which is as limited and less accessible as gasoline-only refueling. This test aims to propose a solution that will allow electric vehicles to charge their batteries during short stops at traffic lights, thereby increasing their overall range.

The problem of electric car owners

The lack of widespread charging station infrastructure and the limited capacity of electric vehicle batteries compared to traditional gasoline tanks are significant challenges in the adoption of electric vehicles. Additionally, the weight of large batteries can also affect the vehicle’s performance.

To solve these problems, a group of Japanese companies and educational institutions came together to develop this method. innovative charging system.

How does it work

Coils for transmitting electrical energy to electric vehicles are strategically placed only at the entrance of traffic lights where vehicles naturally slow down or stop. The technology allows electric vehicles to charge during these brief stops, adding nearly a kilometer of range in just 10 seconds.

While the concept of wireless charging of electric vehicles has been explored before, this approach focuses on taking advantage of moments when electric vehicles are already slowing down or stopping, thus reducing the need for dedicated charging infrastructure on roads.

The initiative is part of Japan’s broader effort to find innovative solutions to electric vehicle challenges. The testing period, which will last until March 2025, will allow for a comprehensive evaluation of the operational reliability and efficiency of the system. If the trials are successful, the technology could be expanded and integrated into road infrastructure across the country by 2030.

The project has the potential to not only expand the range of electric vehicles, but also help reduce the overall carbon footprint of transportation, making electric vehicles a more viable and sustainable option for the future.

The Kiba trial is being closely watched, and its results are expected to have far-reaching implications for the future of electric vehicle technology in Japan and beyond.
