本田开发边开边充的无线充电路面，将在高速上测试 150 kW 供电
Honda develops wireless EV charging road that can deliver up to 150 kW while driving
本田研发部门与大成建设等合作开发了动态无线充电技术：埋入路面的地面单元同时内置逆变器与充电线圈，车辆驶过即可补电，本田称这是全球首个公开披露的此类配置。单元采用直流配电以减少埋设布线，并可嵌入既有路面的铣刨段，路面与硬件按约 20 吨商用车设计。今年晚些时候将先建测试路做相当于一百万次车轮荷载的耐久测试；明年将在千叶的馆山高速公路项目中测试，计划对大型商用车实现高达 150 kW 的供电，并验证高速行驶下的可靠性。本田也坦言，与传统快充设施相比的经济性仍待评估。
Honda has developed new wireless charging technology that could allow electric vehicles (EVs), including large commercial trucks, to add energy without ever leaving the road.
The technology is being developed by Honda R&D alongside construction company Taisei Corporation and Taisei Rotec. Unlike conventional wireless charging, where a vehicle remains parked over a charging pad, Honda’s system transfers electricity from equipment embedded in the pavement to a vehicle as it drives overhead.
According to Honda, its ground assembly (GA) units contain both an inverter and charging coil. Honda says this is the world’s first publicly disclosed dynamic wireless power transfer unit using this configuration.
The units are connected using DC distribution, which reduces the amount of wiring and number of components that need to be installed beneath the road. They have also been designed to fit into milled sections of existing pavement, potentially allowing the technology to be installed as part of regular road resurfacing work.
Honda isn’t just targeting passenger vehicles either. The companies have designed the pavement and charging hardware to withstand commercial vehicles weighing around 20 tonnes.
A new test road will be built later this year where the system will undergo durability testing equivalent to one million wheel loads, but the bigger test comes next year when Honda and its partners will participate in the Tateyama Project on the Tateyama Expressway in Chiba. The companies plan to test power transfer at up to 150 kW for large commercial vehicles, including whether the system can reliably deliver electricity at highway speeds.
Honda sees commercial transportation and logistics as the most promising early use case. Charging trucks while they are already moving could reduce charging stops, although there is still a major question surrounding the economics of installing charging equipment beneath highways. Honda says the cost compared with conventional fast-charging infrastructure still needs to be evaluated.
