Efacec announced a Wireless Electric Vehicle Charging (WEVC) license agreement with Qualcomm.

As an AC and DC charging station supplier, Efacec intends to also offer wireless charging options for all-electric and plug-in hybrid vehicles.

Details of when we should expect new products have not been released yet.

“Under the terms of the agreement, Qualcomm granted to Efacec a royalty-bearing license to develop, make and supply WEVC systems for the EV Supply Equipment (EVSE) industry.

Being a global leading company providing a wide portfolio of EVSE products, Efacec strengthen its corporate vision – To be the preferred partner in delivering worldwide innovative and customized solutions for energy, mobility and the environment – through its full range of  EV charging solutions, including integration in management systems, for efficient use of electric grid infrastructure. Licensing Qualcomm Halo technology enables the business to expand its portfolio to include innovative wireless EV infrastructure solutions for the global automotive industry and EVSE segment.”

Pedro Silva, Efacec Electric Mobility’s Managing Director said:

“The simplicity and efficiency benefits of WEVC, for industry and ultimately for drivers, are obvious. We will commercialize WEVC infrastructure for our customers, offering smarter and cleaner ways to charge EVs, which complement the offer we have on conductive charging. We believe Qualcomm Halo technology delivers the most advanced and comprehensive WEVC technology available today.”

Steve Pazol, vice president and general manager, wireless charging, Qualcomm Incorporated said:

“We are pleased with our license agreement with Efacec; it further strengthens the Qualcomm Halo infrastructure supply network, offering EVSEs access to our advanced wireless charging inventions for EVs. Qualcomm Halo licensees can commercialize highly efficient, fit-for- purpose WEVC systems, which allow convenient, effortless charging.”

Do we really want to waste 15% of EV charging energy while paying more to
do it?
If you are that lazy to plug in an auto plug like the Tesla Snake or just an arm guided into a cone or V shape guide on the floor to plug
Either of these is cheaper, automatic and 15% more efficient.
Especially in the higher 100kw power levels where it is 15+kw of heat under your EV.


Wireless (inductive) charging will be necessary when autonomous cars become available. It will also be essential for charging EV’s while on the move. I believe efficiency now exceeds 85%.

Why? Why should an autonomous car not park exactly in front of a plug, that comes motor driven out of the charging box and inserts into the cars plug?

I’m not a fan of such wireless systems either. But if they get more people to buy EVs then good.

I don’t know how much robotic arm plug may cost, but I guess it will not be cheap. I doubt it can be made reliable enough to operate when covered in ice, snow, dirt. Any dirt on connectors would mean eventual overheat/fire risk. It may be vandalized too easily. Wireless is so much more convenient and reliable, even if it costs some extra for electricity. I guess efficiency may be improved a bit over time.

Here is in my view, a much better path of conductive based docking that was explored by Richard Factor.


For those that don’t know Richard he is at SETI League fostering the search for extraterrestrial Intelligence.

Wireless charging as its simplicity of operation that is undeniable. At the cost of loss and random induction field that isn’t desirable.
The pet killer case, we can call, or the 15% loss of energy.
We already have a 7% loss in distribution line, and adding 15% more losses to a forthcoming growing load isn’t desirable.
We are constantly force to use more efficient appliance, so this is not the best option.
It wouldn’t be that difficult, much more expensive or space constraining to implement a wired mechanical EVSE. At least in most place.
So in my view, wireless charging should be a second or last option choice.
Considering that you can refuel jetfighter at 600 m.p.h. at 20 000 feet altitude successfully, docking and automatically plugging safely a stand still car wouldn’t be much of a head scratcher.

At jet fighter cost, sure, it is easy ;)) But it can’t match reliability of inductive charging with no mechanical moving parts. Especially in outdoors conditions.

I may imagine some hybrid system, when mechanical construction extends and reduces distance of inductive charging to few millimeters, making it more efficient. But even on multi-million dollar planes you often have extending landing gear failures, and this should be some cheap system that should withstand abuse and rough conditions.

I would hate to see a cat run under there out of the rain or a kid reach under there to get his ball while the car is being charged.

I think the charger should be designed to make contact with the car once the car is in place, so there’s no gap between the charger and the car.
