- Improved safety
The 6 steps of wireless EV charging
From 13 steps to 6 steps. Less than half the effort to charge your vehicle. Why wouldn’t you want to charge wirelessly?
By simply parking over the charging pad, turning off your car, and walking away, your electric vehicle charges. Perfect for charging at home or when you're out and about at the grocery store, restaurant and movies. Every time you park, you charge. We call it PowersnackingTM.
But, before you take the plunge, let’s find out what it’s all about.
How does wireless EV charging work?
Simply put, wireless charging (from WiTricity) uses magnetic resonance to charge your EV’s battery. By parking your car over the charging pad, your car immediately begins charging.
Wireless EV charging is fast and efficient, safe and easy to maintain, simple to use in all kinds of weather, and is future-ready.
What is magnetic resonance?
In its simplest form, magnetic resonance works by creating a wireless transfer of energy between two coils, tuned to resonate at the same frequency. For your electric vehicle, one coil is on the underbelly of your vehicle while the other coil is on the ground – either in your garage, in a parking lot, or on the street (or even buried underground).
Is wireless EV charging as efficient as plug-in charging?
In one word, yes. When it comes to wired vs. wireless EV charging efficiency, wireless charging is just as efficient as a Level 2 plug-in charger. In fact, it’s likely you’re operating in the 20-80% state of charge (SOC) range that your battery likes (and is most efficient). With plug-in charging, it’s less likely that the 20-80% SOC range will be maintained since many drivers tend to forget to plug in. Some drivers even charge only once a week or drive all week and then plug in on the weekend. Not only is this less efficient, but it’s harder on the battery. With wireless charging, simply park and charge.
