Inductive Charging Of Electric Vehicles: Conveniently Inefficient

Inspired by a post on, Wireless Charging for Electric Cars Is Cool but Totally Unnecessary

Inductive charging, or wireless charging, is the use of electromagnetic fields to transfer power from one source to another. It’s all about the coils and when inductive charging technology is applied to electric vehicles, it only has to park or drive over a pad to receive an electrical current and charge its batteries. No need to plug it in and you get a fully charged EV the next morning or while you drive. Siemens and BMW are partnering on a program to further this technology by installing a inductive charging station in the city of Berlin in two months.

My question: do we really need this feature to get people to purchase electric vehicles? According to Wiki, at its current best, inductive charging is only 86% efficient with the rest of the electrical current being lost as waste heat. Convenience takes precedent over efficiency and that really seems to run counter to the purpose of driving an EV.

We’ll see what happens. When the Rolls-Royce Phantom 102EX electric car rolls out, it’s set to have the inductive charging feature but it won’t be receiving the Jubbling patch. That’s earned by working through some inconvenience and in this case, all that would mean is that you actually have to plug your EV into an outlet.


New Rolls-Royce 102EX Electric Vehicle Debuts At Geneva Motor Show

Rolls-Royce 102EX Phantom at Geneva Motor Show 2011With a price tag of around $1.6 million, the Rolls-Royce 102EX concept car is close to $1.6 million more than I can afford. The Telegraph has a complete run down of the features of this mega EV. A few of the specs to highlight include its range of 125 miles on a single charge and the fact that it’ll be powered by 1400 lbs of lithium ion cells. The Rolls-Royce 102EX will also have the ability to “induction charge.” Basically, you can park it over two pads to re-charge the batteries wirelessly.

All of these features are very cool but is the Rolls-Royce 102EX Jubbling? No, but it’s definitely Jubfurky.
