We’ll Soon Have Wireless Charging For Electric Cars In 10 Minutes

March 15, 2023 (6 months ago)


Due to its outstanding power and lack of connection requirements, induction charging is a very promising option for charging electric vehicles. A group of researchers from Chalmers University in Sweden have created an induction charging system that can produce up to 500 kW of electricity, which is sufficient to quickly replenish the battery of an electric vehicle.

For the market for electric cars, which is expanding at an unprecedented rate, charging presents a big barrier. Sales of electric vehicles have surpassed those of diesel vehicles in numerous nations. Yet, the number of charging stations is very steadily increasing. Thus, creating extremely strong charging mechanisms is essential.


A more workable alternative has been created by a team of researchers from Chalmers University: an induction charging system that can supply an amazing 500 kW of electricity wirelessly. Given that the highest power of the most effective terminals now in use is just 360 kW, this is a noteworthy accomplishment. The system runs at an 80 kHz frequency and is based on silicon carbide semiconductors. This is more than the induction methods used traditionally. Litz wires comprised of individually insulated copper strands are also used by the system to account for the heat produced while charging.

About 1% to 2% of the energy produced is wasted by the induction charging mechanism created by Chalmers University, making it extremely efficient. Comparatively speaking, typical induction charging devices might experience losses of up to 50%. Nevertheless, because it is not deemed required, the researchers do not currently have any plans to commercialise the technology for use by individuals. Instead, they want to focus on industrial applications since they might benefit greatly from the technology’s extraordinary power and efficiency.

The potential of induction charging technology is being investigated by other businesses and producers. Although no information has been made public yet, Tesla hinted to the advancement of its induction charging technology on March 1 during its Investor Day. In March 2022, Volvo put the technology to the test with the XC40 Recharge. While Nissan collaborated with London EV Company Ltd (LEVC) to test it out.

The induction charging mechanism is quite promising and may be able to address several issues that are now plaguing the market for electric vehicles. It is really useful because it doesn’t need connections, produces great power, and is highly efficient. Unfortunately, the technology is still not generally accessible, and the price can be a barrier. But, as the market for electric vehicles expands, it will be even more important to create extremely effective charging methods like inductive charging.


Electric automobiles are becoming and more common as the globe shifts to alternative energy sources. Owners of electric vehicles do, however, face a number of difficulties, one of which is charging. Thankfully, the electric car market is about to undergo a revolution that promises to dramatically alter the landscape: quick wireless charging.

Wireless charging has been available for some time. Yet in the world of electric vehicles, it has only just begun to acquire momentum. By drastically lowering charging times, fast wireless charging advances this technology. Owners of electric vehicles may now easily and rapidly charge their vehicles thanks to this. facilitating their ability to traverse farther distances.

An electric vehicle is often charged via a charging station, which necessitates that the vehicle be physically plugged in. Drivers in a hurry may find it inconvenient as this process might take hours. Fast wireless charging makes the procedure much more streamlined and practical. The automobile will begin charging automatically as soon as the driver parks it on a charging station.

Fast wireless charging has several benefits, but one of the major is the removal of physical connections and connectors. It can be difficult to manage. This greatly improves the usability and convenience of the charging procedure. This is necessary for the mass use of electric vehicles. Also, it lessens the possibility of mishaps when handling wires and plugs.

Fast wireless charging has the additional benefit of being simple to integrate into current infrastructure. Parking lots, garages, and even public roadways may all have charging stations installed. making it easier for owners of electric vehicles to charge their vehicles while they go about their everyday activities. Also, this infrastructure is easily expandable as demand for electric vehicles rises.

Moreover, quick wireless charging is more effective than conventional charging techniques. This is due to the fact that energy is wirelessly transferred between the charging pad and the automobile using resonant magnetic induction. Compared to conventional charging techniques, which may waste energy as heat when charging, this method is more effective.

Before rapid wireless charging becomes commonplace, there are several issues that must be resolved, just like with any new technology. The price of the technology, which is now more expensive than conventional charging techniques, is one of the main obstacles. Moreover, quick wireless charging may not work with all electric car models, which reduces its utility.

In summary, quick wireless charging is the upcoming revolution in the world of electric vehicles. It claims to improve the convenience, effectiveness, and user-friendliness of charging electric vehicles. Fast wireless charging will become a crucial part of the infrastructure required to support these vehicles as the demand for electric automobiles rises. Fast wireless charging has the potential to transform the way we think about electric automobiles and speed up our transition to a more sustainable future with the appropriate investments and technology developments.
