As governments are enforcing regulations to cut the greenhouse gas emissions, electric vehicles (EVs) are rapidly increasing and believed to be the best option so far to replace the traditional ICE (internal combustion engine) ones. In the near future, low emission vehicles will no longer an option but a duty that both suppliers (automakers) and demanders (customers) must take, so in the EV market, a new race has started: finding solutions that are not only eco-friendly, but also able to run farther with less charging time.<\/span><\/p>\n

 <\/p>\n

This is the bandwagon on which manufactures that produce EV batteries and energy companies would like to jump. Battery makers are developing cells with higher and higher capacity, while energy companies are adding more EV charging stations besides (or even in replace of) existing gas stations. However, for vehicles that have really big sizes and need much longer driving range such as electric trucks, aside from high capacity batteries and easy-to-find charging stations, being able to recharge even when they are moving is a solution that they may need. Therefore, an electrified road (or electric road, E-road, EV-charging road, etc.) seems to be the exact thing that EV trucks need.<\/span><\/p>\n

However, how far are we on the developing process of such roads, and where can we find them, are they the future \u201cway\u201d that will replace the current asphalt and concrete roads? We may not be able to give the correct answers or predictions at the moment, but let us take a look at the technologies and see some pros and cons that an e-road can have.<\/span><\/p>\n

In 2018, the world\u2019s first electrified highway that can charge EVs was launched in Sweden, marking an important milestone of the e-road development. Even though the length of the electric pavement is only about 1.2 miles (2km), it lighted the hope of a future where cars can be re-charged while running without worrying about the time to run around just to find an EV charging station or have to stop for a while to be charged.<\/span><\/p>\n

 <\/p>\n

This e-road is called \u201ceRoadArlanda\u201d and it is the result of a collaboration between the famous German multinational conglomerate Siemens and Scania, a Swedish company focusing on lorries, trucks and buses. eRoadArlanda uses a pair of electric rails to transfer energy (electricity) from the rail, which is connected to the power grid, to an EV that is running above it via a movable arm. When the vehicle stops or does not run on the electrified rails, the pantograph is disconnected and now it will go back to be powered by the charged battery cells inside.<\/span><\/p>\n

Many call such way of charging while driving \u201cdynamic charging\u201d, which is in contrasted to the existing charging method that requires the driver to stop the vehicle for a while and plug in a fixed power source.<\/span><\/p>\n
