U.S. and China top wireless charging patents

Nanjing Huaxun News Recently, the internationally renowned patent search company QUESTEL released a report ''Patent Analysis of High-power Wireless Charging Technology for Electric Vehicles, ''stating that the research and development activities of wireless charging for electric vehicles are mainly distributed in the United States, China, Japan, South Korea, Germany, Australia and New Zealand. And other countries. Qualcomm is far ahead of all competitors in terms of the number and quality of patents, followed by the South Korea Academy of Science and Technology, ZTE, BYD, Chery, and Haier are representatives of domestic companies, all of which are among the top 50 in the world in this field.

Wireless charging is just a new function for mobile phones, computers, cameras and other electronic products, but for the electric vehicle industry, it may be the key to start the entire market. At present, traditional automobile manufacturers at home and abroad are more involved in research and development in this field, such as foreign Audi, BMW, Mercedes-Benz, Volvo, Toyota, domestic BYD, Chery and so on. Communication enterprises to Qualcomm, ZTE as the representative, and outstanding performance.

Based on a comprehensive analysis of relevant indicators, the report points out that Qualcomm's patents are heavily cited, coupled with the largest number of patents, making it a well-deserved king of innovation in this field. ZTE's patents meet or exceed the average in terms of originality, versatility, leading index, company fence index, etc. Among them, "ZTE's patent citations have done a good job compared to other domestic rivals, and its technical strength is reflected not only in quantity but also in quality. At the same time, ZTE's patents are applicable in more areas, not only in the field of wireless charging for electric vehicles. The patent layout is also wider, with ZTE's patents in Australia, France, Brazil, the United States, Germany and Japan, in addition to China." Nanjing Huaxun thinks.

At present, ZTE wireless charging technology has applied for dozens of patents. Based on the development direction of the country's emerging strategic industry of "new energy vehicles", ZTE launched "smart wireless charging" in 2014, and developed a series of high-power wireless charging products with independent intellectual property rights and leading in the world for new energy vehicles, including 3.3/6.6/30/60KW and other power modules, which can be applied to different application scenarios to achieve a system transmission efficiency of 90%, close to 93% of the nominal value of traditional wired charging methods, breakthrough 20CM air gap wireless charging spacing.

It is reported that ZTE's wireless charging bus scheme, which uses this technological breakthrough, has solved the current problems in the promotion of electric buses. It has five major advantages: "the station does not use land, the car does not gain weight, the charging does not start, the road does not run for nothing, and the electricity does not discharge". It can have a revolutionary role in accelerating the construction of electric vehicle charging infrastructure and improve the investment efficiency exponentially, solve the "long-standing" problem of building a large number of charging facilities in the core of the city. At present, ZTE has achieved manned launch in 10 lines in 9 cities, and has actively participated in the completion of the national standard project and the published Shenzhen local standard "Electric Vehicle Wireless Charging System".

With the release of ZTE's M-ICT2.0 VOICE strategy, ZTE believes that the "energy Internet" revolution set off by technologies such as distributed grid-connected power generation, smart wireless charging, microgrids, new energy vehicles, new lithium batteries, and energy routing and switching is emerging. In the future, ZTE hopes to lay wireless charging equipment under major roads around the world. Wireless charging can "empower" moving vehicles anytime and anywhere, and everyone can get what they need. ZTE will take green (Green) as its mission, actively expand the sharing economy business model innovation, research and layout of "new energy vehicles, new lithium batteries" and other new green technologies, and combine the development of Internet technology to provide "energy" for the new technological revolution and industrial development of the "energy Internet".
