Electric cars are confidently conquering the automotive market, taking the share of traditional cars with internal combustion engines. Along with many advantages, they also have a significant disadvantage - long charging times.

Scientists have invented a new way to charge electric vehicles

Many modern developments allow reducing the charging period to 30-40 minutes. And there are already projects with an original solution that will reduce this process to 20 minutes.

Innovative development

Recently, scientists have been able to create a unique way to further narrow this gap. Their idea is based on the principle of magnetic wireless charging. The innovation allows charging the machine without having to stop.

The idea first appeared in 2017. It was shared by Stanford University Electronics Engineer Sh. Fan and PhD student S. Asavarorarit. Initially, the idea turned out to be unfinished and impossible to use outside the laboratory. The idea seemed promising, so other scientists from the university took part in refining it.

How the system works

The main idea of ​​the innovation is that charging elements are installed in the roadway. They must create a magnetic field with a certain vibration frequency. A rechargeable vehicle must be equipped with a magnetic coil that picks up vibrations from the platform and generates its own electricity. A kind of magnetic generator.

Wireless platforms will transmit up to 10 kW of electricity. To recharge, the car must change to the appropriate lane.

As a result, the car will be able to independently compensate for the loss of part of the charge in a few milliseconds, provided that it moves at a speed of up to 110 km / h.

The only drawback of such a device is the ability of the battery to quickly absorb all the generated power. According to scientists, the system is harmless to people, although a constant magnetic field will be present in the area of ​​the car.

The innovation is fresh and promising, but scientists will not be able to turn it into reality soon. It may take several decades. Meanwhile, this technology will be tested on robotic vehicles and drones used in closed areas of large factories.
