With the gradual increase in the penetration rate of electric vehicles, the development technology of electric vehicles has matured and has entered the stage of large-scale commercial use. This undoubtedly brings significant development opportunities to diversified charging technologies. Wireless charging is coming to us at a fast pace.

Wireless charging technology is the top priority of the national "Plan"

In 2016, the National Development and Reform Commission and the National Energy Administration issued the "Energy Technology Revolution and Innovation Action Plan (2016-2030)" (hereinafter referred to as the "Plan"). The overall goal of the "Plan" is: By 2020, my country's energy technology innovation system will be preliminary Formation; By 2030, the energy industry can support the coordinated and sustainable development of my country's energy industry and the ecological environment, and enter the ranks of the world's energy technology powerhouses. Among them, it is clear that by 2020, wireless charging of electric vehicles will be the breakthrough point and application target, and high-efficiency, low-cost wireless power transmission systems will be developed to realize stop-and-charge, even while driving. The "Plan" proposes to master flexible DC transmission and distribution technology, new large-capacity and high-voltage power electronic component technology in terms of key technological innovation of modern power grids; breakthrough electric vehicle wireless charging technology and promote its application. Master low-cost, quantum-level communication security engineering application technology suitable for power grid operation requirements, and realize large-scale applications.

Automobile companies scramble to study wireless charging technology

In the global automotive industry, many automotive companies have taken the lead in the field of wireless charging. The BMW i8 safety car has already used Qualcomm Halo wireless charging technology, and a plan has also been developed to install wireless charging systems for several cars. Dongfeng Nissan Passenger Vehicle Company will work with WiTricity to develop a new wireless charging technology for electric vehicles. Nissan's next-generation Leaf electric car will be able to achieve wireless charging. The Mercedes-Benz brand as early as 2015, Qualcomm jointly announced the development of wireless charging technology for cars, and will apply the wireless charging function on the 2017 S550e hybrid version. In addition, last year, ZTE and Dongfeng Motor jointly built the world's first wireless charging bus demonstration line in Xiangyang, Hubei. Following ZTE, Bombardier started the construction of the first bus wireless charging line in Qingdao. Witricity Senior Product Manager Grant Leigh said: "Every global automaker has a wireless charging project, and wireless charging may become a mainstream technology before 2020."
