Fast Charging And Battery Swapping Stations Have To Be Back, Have You Ever Seen A Highway That Charges While Driving?
Nov 23, 2023
The range of electric vehicles has always been a problem for consumers, although electric vehicles now have a high range and charging speed, many people are still worried about not having enough power. The best way to solve this problem once and for all is to have electric vehicles that can be charged while driving, just like high-speed rail.
This idea is not impossible to realize, and Sweden in Europe is experimenting with such technology. Sweden is a country with a high penetration rate of electric vehicles, but their power facilities and population density are not suitable for building a large number of charging stations, so they thought of charging electric vehicles on the road.
The technology was inspired by the early days of cable cars, which drew electricity from the grid via contact wires on the roof and cables on the road. However, such technology limits the freedom of the vehicle, and it can only drive on the road with cables, and cannot drive as much as it wants.
Engineers in Sweden came up with a better way to do it by burying the cable under the road and inductively installing a receiver under the vehicle to enable wireless charging. Such technology is like wireless charging for mobile phones, as long as the vehicle is driving on the road, it can constantly replenish the power without worrying about running out of power.
At present, Sweden has built a 1.6-kilometer wireless charging test road, although the charging efficiency is not very high, but it is relatively safe and does not affect driving. Sweden also plans to open a 21-kilometer wireless charging road in 2025, and by 2045, such roads will reach more than 3,000 kilometers.
Although this technology is very promising, there are also many difficulties, such as too high construction costs, too large weather factors, unstable charging efficiency, and so on. But if these issues can be overcome, the wireless charging road will revolutionize electric vehicles.
