Charging electric cars at traffic lights.
Near the Japanese capital Tokyo, in the city of Kashiwa-no-ha, testing of wireless charging of electric cars at traffic lights has begun. The pilot project is a joint effort between the universities of Tokyo and Chiba, as well as nine other companies, including well-known tire manufacturer Bridgestone.
The charging system, developed at a Tokyo university, is now being tested for charging capability and durability. The system consists of off-the-shelf charging coils embedded in the pavement in front of traffic lights. Wireless charging starts as soon as the system detects a car above it.
How many kilometers can such charging add?
For such charging to work, cars must be equipped with special equipment near the tires. According to scientists, just 10 seconds of driving over the coils should add about one kilometer of mileage. One minute of waiting at a red light could potentially charge up to 6 kilometers of mileage, which is quite impressive for urban distances. If such a system were installed at every traffic light, the effect would be significant.
The experiment will run from October to March 10 under the supervision of Japan’s Ministry of Transportation. If the pilot program is deemed a success, the system could be expanded to other intersections, not only in Kashiwa no ha, but also in other cities in Japan.
A paradigm shift in urban mobility.
The electrification of transportation is growing worldwide, with governments and automakers striving for more sustainable and environmentally friendly modes of transportation. In this context, the new Japanese approach to charging electric vehicles during short stops at traffic lights is a welcome addition to the ongoing shift towards greener urban mobility.
Groundbreaking wireless charging.
Wireless charging technology has been developing rapidly in recent years, making it a very real solution for electric vehicles. A Japanese experiment takes advantage of this technology by turning ordinary traffic lights into charging stations. This approach reduces reliance on traditional charging infrastructure, further facilitating the integration of electric vehicles into urban environments.
Imagine a future where daily commutes not only save money on fuel, but also increase the range of an electric vehicle without the need to make an extra stop to charge. The concept of wireless charging could greatly increase the convenience of electric vehicle ownership and possibly make it more appealing to consumers.
Reducing range anxiety.
One of the main concerns of electric car owners is the fear of running out of charge before reaching a charging station. An innovative Japanese approach directly addresses this problem by allowing cars to recharge their batteries during routine stops at stoplights. This technology can help reduce range anxiety and increase the confidence of electric vehicle drivers.
Economic and environmental impact.
In addition to convenience, wireless charging at stoplights can have significant economic and environmental benefits. It can reduce the need for large, expensive charging stations and minimize the need for street charging infrastructure. In addition, reducing the number of cars idling while waiting for a green traffic signal can reduce urban air pollution.
The future of urban mobility.
Japan’s pilot program demonstrates the forward-thinking mindset needed to shape the future of urban mobility. The success of this initiative could pave the way for wider adoption of wireless charging technology at traffic lights and beyond. As the world shifts to cleaner and more sustainable modes of transportation, innovative solutions like this are a beacon of hope for creating greener and smarter cities.
