■WiTricity's wireless charging technology and products for EV

WiTricity is a high-tech company founded in 2007 as a spin-out of the Massachusetts Institute of Technology (MIT) by a team of physicists who were developing EV wireless charging technology.

WiTricity's wireless charging system "WiTricity Halo™" uses magnetic resonance method to supply power by resonating a magnetic field between a charging pad installed on the ground and a power receiver pad installed in the EV. This means that no cables are required to connect the EV to the charging device. Simply parking the EV over the charging pad and then turning off the engine (the power switch) will automatically start charging the vehicle. This system has a standard power delivery of 11 kW, enabling vehicles to be charged at the same power transfer rate and charging time as level 2 charging systems that require a cable. The receiver installed in the vehicle can be used with PHEV and BEV type vehicles. It is also possible to retrofit the receiver into existing EV depending on the model of the vehicle.

Furthermore, maintaining a constant EV wireless connection while using V2H (Vehicle to Home) and V2G (Vehicle to Grid) technology enables the EV to be used as a distributed power supply and emergency power supply. It is also expected that in the future it will be possible to charge vehicles while driving over roads with built-in charging equipment.

Sinanen Holdings and WiTricity entered a basic agreement in June 2023 to build a partnership so that both companies can expand sales of WiTricity brand products in the Japanese market. As a business partner for expanding WiTricity in Japan, Sinanen Holdings aims to import and sell WiTricity products in Japan to the general public through its subsidiary Sinanen Co., Ltd. Sinanen will also use its resources and those of the Group companies to promote the installation of receivers into existing EVs as well as install and increase the number of charging stations that have both wall boxes and charging pads.
