Siemens invests in WiTricity to advance wireless charging for electric vehicles

  • The companies will work together to drive adoption of open, interoperable standards in wireless charging for global electric vehicle (EV) infrastructure
  • Siemens makes strategic investment in WiTricity and licenses their technology for future wireless EV charging products

Siemens invests USD 25 million and purchases a minority position in WiTricity, a wireless charging technology firm based in the United States. Siemens and WiTricity will collaborate to drive innovation in the expanding wireless EV charging industry. According to Siemens’ projections, this market will be worth USD 2 billion by 2028 in Europe and North America alone. The two businesses hope to address gaps in global wireless charging standardization for electric passenger and light duty commercial vehicles, enabling interoperability between vehicles and infrastructure and assisting in market adoption. Furthermore, both parties will work together to enhance the technological development of wireless charging systems.

“Combining Siemens’ global footprint and EV charging portfolio with WiTricity’s innovative technology is the first step towards elevating our offering in the wireless charging space. This will speed up deployment of wireless charging technology, support standardization, and advance public charging infrastructure with interoperable solutions for drivers’ convenience,” said Markus Mildner, CEO of Siemens eMobility. 

Siemens will also become a technology license partner, leveraging WiTricity’s extensive knowledge and decade-long engagement with major automobile OEMs to produce field-tested, interoperable wireless charging systems.

Innovative and proven technology

A charging pad mounted on or in the ground exchanges power with a receiving coil attached on the underside of the EV. There are no moving parts or physical connectors. Instead, a magnetic field transfers energy between the charging pad and the vehicle coil when the vehicle is over the charging pad. The system uses resonant induction between the charger and receiver in order to provide high efficiency at a variety of ground clearances, from low-slung sports cars to SUVs. 

Cost-effective, global availability, addressing customer demands

The ultimate goal of the collaboration is to accelerate the maturing of wireless charging technologies together with OEMs and infrastructure partners to simultaneously ensure their cost-effective availability worldwide. A recent survey of more than 1,000 current and future EV owners interested in purchasing an EV in the next two years indicated that wireless charging was one of the highest-rated add-ons and a more preferred option to other amenities, including park-assist, performance, or premium audio packages. 

“Wireless charging enables a driver to just park and walk away, returning to a charged vehicle. Wireless charging makes EVs more appealing for individual owners and more cost-effective for commercial operators. We are excited to partner with a leader like Siemens to help drive this new world of compelling solutions,” said Alex Gruzen, CEO of WiTricity. “Siemens and WiTricity share the goal of improving EV ownership and fleet management with the matchless simplicity and reliability of wireless charging”.

Eliminating autonomous vehicle friction points

For autonomous vehicles to fulfill their promise key friction points will need to be removed, such as charging, which today still requires human intervention. Wireless power transfer will be the key technology to enable contactless automatic charging with least maintenance requirements and pave the way to an all-electric, fully autonomous mobility future.
