SAE International announced approval of the “SAE TIR J2954 Wireless Power Transfer for Light-Duty Plug-In/ Electric Vehicles and Alignment Methodology”.

Thankfully to this decision, we will finally see mass adoption of the electric vehicles – all-new standard has a huge potential.

Even CHAdeMO charging method is not as cool as this one.

Some history

6142.jpgSAE TIR J2954 is the first step in standardization and was developed by SAE International’s PHEV/EV Wireless Power Transfer committee, established in 2010.

TIR J2954 WPT compatible systems have been built by automakers and suppliers and are currently under test with a cross-industry team with the US Department of Energy, Idaho and Argonne National Labs. The test data, first in the bench and later in the vehicle, will be used to finalize the Standard by 2018 to support the roll out of this technology.

For more information about “SAE TIR J2954 Wireless Power Transfer for Light-Duty Plug-In/ Electric Vehicles and Alignment Methodology,” visit http://standards.sae.org/j2954_201605/

What are the requirements?

The SAE TIR J2954 protocol requires the use of the 85 kHz (81.39 – 90 kHz) frequency, and defines four classes/power levels (new higher levels will be added later):

         3.7kW (WPT 1) specified in TIR J2954          7.7kW (WPT 2) specified in TIR J2954          11kW (WPT 3) to be specified in revision of J2954          22kW (WPT 4) to be specified in revision of J2954

Where can I read this standard?

The documentation is available in here….

Nevertheless, don’t hurry up --the standard won’t be officially finalized until 2018—so, the possibility of some changes is high as hell.

Accolades from Jesse Schneider

Jesse Schneider (the Chair of SAE International’s Wireless Power Transfer committee and is the Fuel Cell, Electric Vehicle and Standards Development Manager at BMW North America) said:

6144.jpg“Wireless power transfer, using SAE TIR J2954 is a game changer for plug-in hybrids and electric vehicles. This first in a series of documents will enable consumers to simply park their vehicles into spaces equipped with TIR J2954 equipment and walk away without doing anything to charge their PH/EV.”

“Standardization of both the vehicle and ground infrastructure WPT has started with SAE TIR J2954. The frequency band, safety, interoperability, EMC/ EMF limits as well as coil definitions from SAE TIR J2954 enable any compatible vehicle to charge wirelessly from its WPT home charger, work, or a shopping mall WPT charger, etc. with the same charging ability.”

6143.jpg“All of this makes it possible to seamlessly transfer power over an air gap with high efficiencies. SAE TIR J2954 WPT automates the process for charging and extends the range for the vehicle customer only by parking in the right spot.”

Well, sounds like a lot of fun is coming.

Let’s thank SAE International for the SAE TIR J2954 standard approval and wait more news to be coming.

    I recently built mine and I was looking for some design ideas and you gave me a few. Now I can focus on how I can make my sidings look minimal inside and outside. But one of my friend suggested me this www.columbiavinylsiding.com website. I will take a look later.
