The road that can be wirelessly charged, the electric car can also be charged on the road
The increasingly popular electric vehicles, like other products powered by electricity, cannot avoid the problem of "charging". In this regard, electric vehicles are somewhat similar to mobile phones. They are usually driven by batteries. Although there are electric buses that are not troubled by electricity, they need to be connected to the power grid above to maintain operation.

When the battery is about to run out, whether it's a mobile phone or an electric car, it usually needs to be connected to charge. However, many mobile phones now can be wirelessly charged, and it is more convenient to take them while charging, but electric vehicles have to be "trapped" in front of the charging pile.

Today, electric vehicles can also be charged wirelessly. Not long ago, Israeli company Electreon announced plans to deploy its first public wireless electric vehicle charging road system in the United States. The pilot project will be completed next year in Detroit, Michigan, and is scheduled to be operational by 2023.

Electreon works with NextEnergy and Jacobs Engineering Group, among others, to design, evaluate, iterate, test and implement projects. The current plan is to enable dynamic and static electric vehicle wireless charging on roads of about a mile in length.

Electreon's technical solutions include underground infrastructure, vehicle-side technology and charging management software. Under the road there will be an underground network of charging copper coils connected to the energy grid, with receivers on the cars that need to be charged.
When the vehicle is over the road segment, the management unit transmits power from the grid to the road wireless charging coil segment. The vehicle unit then receives wireless energy from the wireless charging coil and transmits it to the vehicle battery, all of which can be monitored in real time through cloud-based management software.

The receiver installed on the charging vehicle is to realize charging while driving, which is actually a safety guarantee. Because the system does not generate electricity without an active receiver, pedestrians and animals crossing the road will not be electrocuted if they come into contact with the road.

In addition, Electreon's system is modular, and each coil is individually connected to the grid, so even if there are potholes on the road, it will not affect the use of the entire charging system.

With this system, electric vehicles can be charged in different scenarios. It can be statically charged in places like bus stops, loading docks and car parks, like many charging stations today.
It can also dynamically charge vehicles that are traveling along daily routes, such as point-to-point trucks, buses and BRTs; it can also perform semi-dynamic charging, such as those waiting in queues for taxis, in logistics hub ports and traffic light areas slow-moving vehicles…

Given the way the road works and the cost of laying it, it's obviously not realistic to use it to replace the existing EV charging model, but it is a desirable charging method for buses that travel on a fixed route.

When there is a traffic jam, the "turtle speed" traffic flow consumes not only time and electricity, but also the confidence of electric vehicle owners in electricity. If it is on a road that can be wirelessly charged, the car can be charged while waiting, at least to extend the driving time of the electric car stuck on the road before reaching the charging station.
