Why wireless charging could be the next big EV upgrade

Wireless charging is a technological innovation that, if fully implemented on a large scale, will revolutionize the electric vehicle segment.

Wireless charging is likely to become the next big thing for electric vehicles (VE), with ambitious technology ready to offer several advantages to drivers. The adoption of electric vehicles often comes up against doubts about the reliability and lifespan of the batteries. To increase ridership, automakers regularly release updates to increase the range and battery capacity of their electric vehicles. Governments around the world have also encouraged the purchase of electric vehicles by offering tax credits and other incentives.

In the coming years, electric vehicles are expected to take center stage in the automotive industry, but cdraining them can be frustrating, especially on long trips where proper planning is required to ensure the battery doesn’t run out in a remote area. Previously, drivers did not have to worry about this, as gasoline vehicles could be recharged at any gas station. In addition, gas stations also have a high density compared to the limited number of charging stations. Today, drivers not only have to find a charging station, but also ensure that it is compatible with their vehicle. Besides being tiring, it can discourage more drivers from giving up gas-powered vehicles.

Wireless charging has been around for a long time, although its adoption on a commercial scale has been quite slow. Its origin dates back to the 19th century when Nikola Tesla presented a magnetic resonance coupling that transmitted electrical energy through the air using a magnetic field between two circuits. Wireless vehicle charging works the same way as wireless smartphone charging, although much more on a larger scale. As Green Car Reports explains, wireless electric vehicle charging also adopts electromagnetic induction to transmit power through the air as a magnetic field, just as Nikola Tesla demonstrated all those years ago.

The EV benefits of wireless charging

Wireless charging can benefit the driver for many reasons. A significant advantage is that the vehicle can be charged while in motion, as opposed to charge the parked EV and waiting for a full charge. Since wireless charging works automatically, there’s also no need to plug or unplug cables, protecting against human error. With wireless charging, there is also less risk of short circuits and other power failures. Not to mention, since there is no need to plug and unplug the cable to charge the vehicle, the likelihood of wear and tear is greatly reduced. With wireless charging, oxidation or degradation of electronics becomes less of a concern as connections are closed, depending on CarBuzz. Wireless charging also makes it convenient for charging electric vehicles since the driver only has to park at the charging station and wait for the electric vehicle to be fully charged.

With so many benefits offered by wireless charging, it’s easy to see why this is the next big upgrade for EV. That said, when the upgrade will actually happen is another matter entirely. While some believe it will manifest soon, others suggest the technology needs more time. To date, there have been a few attempts to integrate wireless charging. As CarBuzz explains, German automaker BMW has undertaken a minor pilot program to test wireless charging using its 5-series plug-in hybrid.
