WiTricity licenses wireless charging patents to TDK
Wireless charging pioneer WiTricity has announced an intellectual property license agreement with TDK Corporation, which will enable the Japanese firm to commercialize WiTricity’s patented technology to create wireless charging systems for carmakers. TDK may be most familiar to (older) US readers for its high-quality cassette tapes, but in fact its forte is the manufacture of… Read more »
WiTricity to provide wireless charging technology for Prius Plug-In
The Prius Plug-In is going wireless, and WiTricity will be providing its resonant power transfer technology. This week, the Massachusetts-based MIT spinout announced an intellectual property license agreement with Toyota, which has been an investor in WiTricity since 2011. Toyota announced plans to add wireless charging to the Prius line in August. “We have heard… Read more »

WiTricity introduces simulation environment for wireless power transfer systems
Wireless charging pioneer WiTricity has announced a new software application for designing and developing highly resonant wireless power transfer systems. WiCAD is an end-to-end simulation environment designed to enable developers to streamline the design process and avoid the high cost of trial-and-error physical prototyping. WiCAD provides a library of commonly used WiTricity energy transfer designs… Read more »
Resonating with the OEMs: WiTricity’s wireless energy transfer technology
WiTricity hopes to leverage a wireless energy transfer breakthrough out of MIT into a commercial solution with far-reaching potential Inside a standard electrical transformer are two coils that transfer power wirelessly. They utilize the principle of magnetic induction, sending energy from a primary coil to a secondary coil without a direct electrical connection. Inductive chargers,… Read more »
SAE International announces alignment methodology for wireless EV charging standard
SAE International’s Wireless Power Transfer & Alignment Taskforce has been working on a new wireless EV charging standard for some time. Now, following a “lengthy consensus process,” the group has decided upon Differential Inductive Positioning System (DIPS) as the technology alignment methodology for the SAE J2954 standard, Wireless Power Transfer (WPT) for Light-Duty Plug-in/Electric Vehicles… Read more »
CharIN launches new taskforce for wireless power transfer
The Charging Interface Initiative (CharIN) is a global alliance of EV and EVSE providers that promotes universal charging standards such as CCS, MCS and ISO 15118. Now CharIN has launched a Wireless Power Transfer Taskforce, initiated by Siemens, WiTricity, and MAHLE, in order to drive the adoption and standardization of wireless charging solutions for EVs….

Tesla acquires German wireless charging startup Wiferion
Is Tesla planning to go wireless? The company has long touted autonomous driving technology, which will require some form of automated charging. In 2015, Tesla showed a prototype of a gee-whiz “snake charger.” In 2017, there were rumors that it was working on a ground-mounted automated conductive charger. This March, Tesla teased what appeared to… Read more »
A primer on wireless EV charging technology
Two main types of wireless power transfer systems are being pursued these days: the inductive type, which is magnetically coupled, and resonantly-coupled systems using electromagnetic fields. The instant availability of maximum torque makes driving even the most economy-oriented EV way more fun than its ICE counterpart, but few would hold the same opinion about the… Read more »
