If you have an electric vehicle, it's a given that you'll have to find an outlet so you can regain those precious electrons. Your car runs on electricity, after all. How else are you going to charge it?

Well, there could be a more simple solution to your charging needs in the future, and Engineering Explained got to sample it firsthand.

While attending the recent Formula E race in Long Beach, California, Jason Fenske, the host of EE, learned that Qualcomm has created a system for wirelessly charging electric vehicles. The pace car and safety car for the race was a BMW i8. To keep its battery pack topped off, the BMW was parked over a charging pad that worked with an embedded antenna in the bottom of the car. Together, this system was able to recharge the BMW's battery.

To understand how this is possible, Engineering Explained, ahem, explains how inductive charging works. It's all about coils and magnetic fields, and we're pretty sure there's a part about witchcraft as well. Of course, EE conveniently leaves that bit out.

However, EE also points out a game-changing real-world application for this type of system in a sort of electric car utopian future. It's interesting stuff to think about.

Like any Engineering Explained video, you're about to have some knowledge dropped in your lap. Soak it up like an i8 gathering electrons.
