A rendering of a public wireless charging point. WiTricity expects that most wireless chargers will be installed at home. WiTricity – In the most recent explanation on Electric vehicle charging, there is no talk about wireless charging. But, Wireless Electric vehicle charging is now standard on smart devices. However, it works similarly on cars with higher power and larger batteries. However, the technology fell off the radar after some demonstrations and news releases in the mid-teens.
In the background, engineers were working to establish an industry standard. This was made possible by industry consolidation. Now, the final version is available, and the first EVs equipped with factory-fitted wireless charging systems are beginning to arrive in the US. As a result, the potential adoption of the EV is high, even for those who cannot imagine life without it.
Ars was the first to see wireless car charging in 2015. In 2015, Qualcomm, a chipmaker, was developing what it called Halo. It was demonstrated at Formula E races. The safety car was a BMW i8 plug-in hybrid, charging the battery. However, it wasn’t the only company that was developing wireless charging. After an investment from Toyota, WiTricity, a spinoff of MIT in Massachusetts, began exploring wireless car charging in 2010.
There’s now a standard. Alex Gruzen, CEO of WiTricity, stated that they fully engaged in a standards group at the SAE (the Society of Automotive Engineers) to set a global standard.
The view was that cables were a mess. There are different automakers in different regions and different connectors. Cables have also been inconsistent with standards. They said that wireless was the next thing and would do it once. Let’s make it one global standard organization led by the SAE. All the automakers began to engage, and the primary technology providers in the standards effort were WiTricity (and Qualcomm Halo). While each company may have contributed in some ways to the technology, we used many architectures, which confused and slowed progress.
In 2019, WiTricity purchased Halo and spent the following year integrating the best parts of each system. Gruzen stated that the acquisition was approved and completed by October 2020. “So, once we had completed the purchase, we brought one architecture to the industry and one IP portfolio that anyone could license.
