Wireless EV chargers eliminate many of the hassles and snags that are sapping the performance and reliability of plug-in chargers, according to Richard Truett, reporter covering technology and engineering for Automotive News. “After testing a wireless charging system made by WiTricity Corp., there’s no doubt in my mind that it is far better than any plug-in EV charger.”
With wireless charging, there’s no button to press to open a charge port door. No plugs to deal with. No credit card information to input. Wireless charging can also make living with an EV easier for physically challenged drivers.
In light of the article mentioning charging efficiency (and contrary to what is mentioned, the efficiency of wired and wireless chargers is very similar), it’s important to remember that EV drivers are concerned about the number of miles of charge they can add in how much time. Not efficiency. Of course, the number of miles added depends on state of the battery, the capacity of the on-board charger (OBC), wattage of the charger, outside temperature, etc. This article provides a side-by-side comparison of wired to wireless charging.
