据日本经济新闻等媒体报道，由东京大学、千叶大学、普利司通、三井不动产等 9 家公司组成的联合研究小组，于本月初在日本千叶县柏市的“柏之叶智慧新城”开始了公共道路电动汽车无线充电设施的系统实验。该项目在交通信号灯前面等“关键位置”将输电线圈嵌入路面，因为这些位置的车辆大多会缓慢行驶，以方便充电。该设施预计可在 10 秒钟内为一辆普通电动汽车补充约 1 公里的续航。为避免浪费能源，输电线圈并非始终处于通电状态，而是安装了感应系统：车辆靠近时才会工作，待机状态下可保持最低功率。据东京大学大学院新领域创成科学研究科官网介绍，该项目有三个要点：实现可用于各种车辆的在途供电系统、实现标准化的在途供电系统、开发既能安全使用、又能传输电力且具备高耐久性的路面线圈。
本次实验的成功，将为未来的智能交通系统和电动汽车无线充电技术的发展提供有力支持。在未来，公共道路电动汽车无线充电系统将有望成为现实，为人们的绿色出行提供更加便捷和高效的充电方式。

Japanese public road electric vehicle wireless charging system experiment successful
Keywords: Japan, electric vehicle, wireless charging
On Tuesday, a joint research team composed of nine companies from Tokyo University, Chiba University, Bridgestone, and Sumitomo Realty, etc. began a system experiment of public road electric vehicle wireless charging facilities at the “柏之叶智慧新城” in 柏市，Chiba Prefecture, Japan. The project embeds the wire grid under the road surface at key locations such as traffic signal lights, where most vehicles slow down to make it easier for charging. The facility is expected to charge about 1 kilometer of range for a typical electric vehicle in 10 seconds. To avoid waste of energy, the wire grid is not always on and has an on/off system. The project has three key aspects: realizing a roadside charging system that can be used for various vehicles, standardizing roadside charging systems, and developing a road surface wire grid that can transmit power safely and have high durability.
The success of this experiment will provide strong support for the development of intelligent transportation systems and roadside charging technology for electric vehicles. In the future, public road electric vehicle wireless charging systems may become a reality, providing more convenient and efficient charging options for people’s green travel.
