History

The company was established by Massachusetts Institute of Technology (MIT) professor Marin Soljačić in 2007.[1][2] The MIT spin-off is based in Watertown, Massachusetts.[3] In 2014,[4] WiTricity joined the Alliance for Wireless Power (A4WP), which later merged with the Power Matters Alliance to form the AirFuel Alliance.[3] Alex Gruzen replaced Eric Giler as chief executive officer (CEO) in 2014.[5][6] Morris Kesler serves as chief technology officer (CTO).[7][8] The company is a member of the Wireless Power Consortium.[9]

In 2017, WiTricity began focusing on charging systems for electric vehicles more than consumer technology products.[2] By 2018, WiTricity had partnered with more than a dozen automotive companies, including nine of the world's largest ten, on research and development projects.[10] Audi, Mahle GmbH, and Mitsubishi were among the partnering companies.[6][11]

In 2018, WiTricity was named a New Energy Pioneer by Bloomberg New Energy Finance.[12][13] The company acquired the assets and intellectual property rights of Qualcomm Halo and its inductive charging technology in February 2019; the deal included more than 1,000 patents and patent applications,[14] as well as technology designs and licenses, and made Qualcomm a minority owner of WiTricity.[6][15] In late 2020, MIT and WiTricity filed an infringement lawsuit against the Pennsylvania-based company Momentum Dynamics over seven wireless energy transfer patents.[16]

Funding

Prior to Toyota's investment in 2011, WiTricity had raised approximately $15 million.[17] By April 2013, WiTricity had received approximately $45 million in funding.[1] After additional funding rounds in 2015 and 2018, the company had raised $68 million.[2] WiTricity had raised approximately $88 million in venture capital by early 2019.[14] Funders have included Delta Electronics, Foxconn, Haier, Intel, Schlumberger, and Toyota.[14][18]

In 2020, WiTricity completed a $34 million round led by Stage 1 Ventures with additional participation by Air Waves Wireless Electricity and Mitsubishi subsidiary Mitsubishi Corporation (Americas).[19] The round was extended for an additional $18 million raised in January 2021; Tony Fadell was among the private investors and joined WiTricity's advisory board.[20][21]

In August 2022, WiTricity completed another round of funding raising $63 million.[22] The round was led by Siemens which invested $25 million and acquired a minority stake in the company earlier in June 2022.[23][24] Mirae Asset Capital and Japan Energy Fund joined the round along with few other returning investors.[22]

Technology

WiTricity's technology allows wireless power transfer over distance via magnetic resonance.[1] Alternating current (AC) electricity runs through an electromagnetic coil within a charging station to form an oscillating electromagnetic field.[25] Another coil resonating at the same frequency captures the field's energy and a rectifier delivers direct current (DC) current to a battery management system.[3] The technology works through various materials, such as stone, cement, asphalt or wood, and has an energy conversion efficiency end-to-end above 90 percent, equivalent to plugging in. By 2013–2014, electric power output had reached 10 W for mobile devices, 6 kW for passenger vehicles, and 25 kW for fleets and buses.[5][26] WiTricity's EV has charging rates from 3.6 to 11 kW, and the technology scales up to hundreds of kilowatts for heavy duty vehicles such as buses.[27]

Uses

WiTricity has reached licensing deals with Anjie Wireless,[28] Delphi (Aptiv), Intel,[5][29] Mahle, TDK, Toyota,[3][14] and Zhejiang VIE.[27] Thoratec licensed the technology to produce heart pumps capable of charging automatically.[4] WiTricity has demonstrated wireless charging for consumer products such as laptops, mobile phones, televisions,[30] and solar panel receivers.[31] The company has also shown how the technology can be used to power soldiers' helmets with night-vision goggles wirelessly during Humvee transportation.[32] Dell's 2017 launch of the laptop-tablet Latitude 7285 marked the first commercial consumer product to use the technology.[3]

In 2018, BMW's 530e iPerformance became the first vehicle factory equipped with wireless charging,[15] and Hyundai's Kona also demonstrated use of the technology.[10] In January 2019, Honda and WiTricity demonstrated wireless vehicle-to-grid charging at the Consumer Electronics Show.[15] The technology was also being used for the McLaren Speedtail Hyper-GT by 2020.[19][33] In May 2020, China published their national standard for EV wireless charging which incorporated WiTricity's technology,[34][35] and WiTricity played a key role in establishing SAE International's J2954 standard for wireless power transfer.[33][36]

In 2022, WiTricity received a $50,000 grant from the Michigan Mobility Funding Platform and the State of Michigan to install a wireless charging station at the Detroit Smart Parking Lab, operated by the American Center for Mobility.[37][38]

The 2022 Hyundai Genesis GV60 uses wireless charging hardware by WiTricity.[39][40][41]

In 2022, WiTricity licensed its technology with Wiferion, which develops wireless charging systems for industrial applications such as automated guided vehicles, cobots, and trucks.[42][43]
