Recently, Toyota announced the use of 5,680 patents related to 5680 fuel-powered lithium battery systems (including patents in the application). The content includes: in the early days of the market, about 1970 fuel power lithium battery packs, about 290 high-pressure reservoirs, about 3,350 fuel-powered lithium battery control systems, and about 70 patents related to hydrotation station, patent coverage Hydrogen fuel power lithium battery system industrial chain. Compared to the industry's relative conservative understanding of Toyota open technology, and the protection initiative to the industry's memory is still new to hybrid automobile technology patents (1997 Toyota first generation hybrid motivation Puris put on the market; hybrid automobile technology Patented Protection Date 2015).
There is media analysis, this is Toyota PK Tesla pure electric car technology route, Tesla CEO Mask has published unchaul reminders in Toyota hydrogen-fuel power lithium batteries, and Tesla announced all over June 2014 The patent (approximately 200 items), and experts say Toyota sincerely needs to be observed. The author does not doubt Toyota sincerely, there is this point of view: First, Toyota is unable to open a lot of patents without a lot of patents in its Mirai, just as the author is in the previous one. In the blog, Toyota intends to lead the world trend in a hydrogen fuel power lithium battery car, and unpaid-free public use rights means that the technical orientation and path of hydrogen fuel power lithium battery automobile technology will be technically controlled.
Moreover, no matter who is free to use, it is impossible to surpass the Toyota accumulated in the hydrogen fuel power lithium battery car technology. This Toyota has confident. Second, different from hybrid vehicles, hydrogen fuel power lithium battery automotive industry chain length, must have infrastructure guarantees, so fuel power lithium battery automobile promotion popularization only relying on a few cars universal, unpaid open patents will promote More companies participate in the development and commercialization of hydrogen fuel dynamic lithium batteries, expand the industrialization scale of key materials and components such as electric reservoirs, and constantly reduce costs, and more importantly, promoting the construction of hydrogen station within the world.
And Hydrogenation Network, Toyota unpaid open its technical patent is the so-called intention of it, it is a wise move. Third, the timetable given by Toyota is to the end of 2020 (hydrogen supply and manufacturing, etc.), which is 6 years.
Why? In the author, the first is that 6 years is enough to get a capable company digestive to absorb Toyota technical patents and achieve commercialization; followed by Toyota hydrogen-fuel power lithium battery automotive technology still faces some topics, such as the further small platinum of electric stack catalysts. Chemical or non-platinuming to reduce costs, topics of high pressure hydrogen fuel tanks: compared to Toyota early hydrogen fuel power lithium battery technology, Mirai is a new renewal mileage, using high pressure gas tanks up to 700 atmospheric pressure to ensure safety The problem of gas tank structure and size is a challenge for vehicle design and total arrangement, and the cost of the hydrogen station is not high. Solving these topics should be Toyota next-generation hydrogen-powered lithium battery car goals, rough judgment this time should be 2020, it can be said that Toyota gives the patent open period must be a prudent issue.
Fourth, how should my country's car companies and related companies see Toyota unpaid open patented technical use rights? The author believes that the hydrogen fuel power lithium battery car is still in the sample development phase, and the technical level cannot be written with Toyota. The industrial chain is basically not formed, using Toyota patent technology to fill in the technology of hydrogen fuel power lithium battery as soon as possible Depression, reduce development, and risk, companies that are interested in developing in hydrogen fuel power lithium batteries should seize opportunities. However, the use of patents can reach Toyota level, but also to see the technology foundation and digestive absorption of my country's car companies and related companies.
It is also not a matter of one or a few cars. It is an industrial chain's overall ability. Of course, some ability Automobile companies should act as an important role in this.
Fifth, the patent use method, according to Toyota's statement, the relevant company uses the patent, to apply to Toyota: "Convergence the specific use conditions, etc. For specific uses to negotiate and sign agreements, Toyota and relevant parties will time consuming, and the actual operational efficiency may be contrary to Toyota's original intention. I look forward to the promotion of Toyota to promote interested companies to efficiently use their patented technology.
