I have promoted electric vehicles for many years, to move this technology into the mainstream for various applications. And today it’s reality, and there’s no turning back.
Today’s battery technology and vehicle designs have made electric vehicles more feasible, but there are many concerns about tomorrow. I often hear questions regarding charging or automated battery changing stations amongst other ways to reenergize power supplies. Most notably “Where do I plug in”?
So let’s talk about tomorrow.
In the future “plugs” will slowly disappear, and transfer of electrical energy performed through magnetic couplings. Yes, a charger with no plug and similar to the electrical transformer, where electrical current is passed from the primary to secondary coil through magnetic field. There is no physical connection, and many charging stations will consist of primary coil that’s coupled to your vehicle through a receiving coil. This transfer of energy will be performed through a electromagnetic coupling. Your vehicle can easily be fitted with receiver coil for coupling into these charging units. It may not look like a charger, but that’s the beauty. No need to turn “ON” and “OFF”, these units are fully automatic. These charging stations will be the size of the bumper or wheel stops located in parking lots all across the country, and placed in these very locations. Parking areas will be designated for magnetic coupled charging, where you can drive to a charging block and couple your vehicle and then do your shopping, work, or just enjoy your leisure time. There are numerous ways to implement charging stations, and make practical.
Another application for the coil located in the front of your car body, will be used for charging your battery on highway sections where superconductive cables were constructed in roads and highways. When electrical current is passed through these cables they generate a magnetic field so electric vehicles can collect energy during long trips. Cities will implement this technology as well, using this energy source to power inner transportation systems using battery power when moving from one cable section to another, and other. There are many applications for charging electric vehicles.
So don’t worry about the plug, it’s going to disappear in the future. Just make certain you have an electric vehicle to take advantage of the new infrastructure being created.
