With the gradual improvement of the penetration rate of electric vehicles, the development technology of electric vehicles has matured and has entered the stage of large-scale commercialization, which undoubtedly brings significant development opportunities to diversified charging technologies, and wireless charging is coming to us.
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 Innovation Action Plan (2016-2030)" (hereinafter referred to as the "Plan"). The overall goal of the Plan is: By 2020, China's energy technology innovation system is preliminary. Formed; by 2030, the energy industry can support the coordinated and sustainable development of China's energy industry and ecological environment, and enter the ranks of the world's energy technology powers. It is clear that by 2020, wireless charging of electric vehicles will be the breakthrough point and application object, and a high-efficiency, low-cost wireless energy transmission system will be developed to realize stop-and-charge, even charging while driving. In the key technology innovation of modern power grid, the Plan proposes to master flexible DC transmission and distribution technology and new high-capacity high-voltage power electronic components technology; break through the wireless charging technology of electric vehicles and promote its application. Master low-cost, quantum-level communication security engineering application technology suitable for grid operation requirements, and realize large-scale application.
Auto companies scramble to research wireless charging technology
In the global automotive industry, many car companies have taken the lead in wireless charging. The BMW i8 safety car has already used Qualcomm Halo wireless charging technology, and has also developed a plan to install a wireless charging system for several cars. Dongfeng Nissan Passenger Vehicle Co., Ltd. will team up with WiTricity to develop a new electric vehicle wireless charging technology. Nissan's next-generation Leaf electric car will likely achieve wireless charging. The Mercedes-Benz brand announced in 2015 that Qualcomm jointly announced the development of automotive wireless charging technology, and will apply wireless charging function on the 2017 S550e hybrid version. In addition, the world's first wireless charging bus demonstration line jointly built by ZTE and Dongfeng Motor last year was launched in Fuyang, Hubei. Following ZTE, Bombardier started the construction of the first bus wireless charging line in Qingdao. Grant Reig, senior product manager at Witricity, said: "Every global car manufacturer has a wireless charging program, and wireless charging may become mainstream before 2020."
