On the day before CES2015, Toyota announced the opening of 5,680 patents for fuel cell technology to the world, including 1970 patents from Toyota's latest hydrogen fuel cell vehicle Mirai, involving fuel cells, high-pressure hydrogen storage tanks, and battery management systems. technology. It should be pointed out that Toyota's fuel cell technology is the world leader, and Mirai is also the world's first fuel cell vehicle that can be manufactured and commercialized on a large scale.
Toyota's generosity is reminiscent of Tesla's decision not long ago. On June 12, 2014, Tesla announced that it would open all patents to the public, with a total of about 200. Its core value is the control technology of the battery pack.
"Tesla uses lithium batteries, Toyota is a fuel cell. In the field of new energy vehicles, this is two different technical routes." Wang Jia, editor-in-chief of Aika Motors, said in an interview: "The two companies The initial purpose is to attract more players to participate in the opening of the technology, to make big cakes. At the same time, to promote the development of basic facilities for new energy vehicles: charging piles or hydrogen refueling stations."
Patent openness lowers the threshold "Battery energy is the core problem that currently plagues all new energy vehicles including smart cars. Battery life is short and charging time is too long, which has hit the needs of users." President of Geshi Automotive Network, well-known car reviews Chen Wenkai told reporters.
In addition, since no single battery can carry the load of the car, the current new energy vehicles are powered by a large number of battery packs, and the battery pack used by Tesla includes thousands of batteries.
“How to get them to discharge quickly when speeding up, to recover power while braking, how to ensure the overall operation when one of the batteries fails, these battery management technologies, few companies can do.†Chen Wenkai told reporters, “Many other companies Often it's a broken piece, the whole can't work, and security is also a problem. The opening of battery management technology can significantly lower the industry threshold."
Wang Wei also told reporters: "In China, many traditional auto companies will benefit from this. Even the beneficiaries will have BAT and LeTV, which recently announced that they will enter the car, which can save them a lot of research and development costs and time." It is reported that Toyota research fuel The battery is close to 20 years.
"Perhaps Toyota Bitsla needs to expand its camp, because the Chinese and US governments now prefer Tesla's direction of rechargeable batteries, and there are not many fuel cell supporters." Chen Wenkai pointed out that the patents of the two companies are open. On the one hand, it is to ripen the industrial chain, on the other hand, it is also the game of the technical route. Both sides are competing for the right to speak. "Reducing the threshold of the industrial chain, in fact, opening more doors for themselves."
Taking the market to promote policy “The first step is to expand the industry. The second step is to use the industry to promote the policy. After all, the charging piles and hydrogen refueling stations of new energy vehicles are inseparable from government subsidies, management and policy support.†Wang He told reporters that "due to Toyota's influence in Japan, Japan has begun to vigorously promote fuel cell vehicle infrastructure, and their plan is to choose to directly build a hydrogen refueling station at a qualified gas station."
Each country's policies are set up for local industries. Taking Beijing as an example, the Beijing government's policy subsidies for new energy vehicles, such as subsidies and unlimited purchases, are basically allocated to electric vehicles. Wang Wei told reporters: "The reason behind this is mainly that Beiqi mainly produces electric vehicles."
As with the speech of Toyota Vice President Carter at the press conference: "The use of fuel cell vehicles requires 'unusually close cooperation' between car manufacturers, governments, energy companies and researchers."
Moreover, it should be pointed out that the opening of patents will not bring uncontrollable competition to the two major companies. "Take Toyota's Mirai as an example. This car uses Toyota's existing 'hybrid car' production line. The parts and components are from the existing supply chain. Thanks to Toyota's production control capabilities, the cost of this car can be controlled. RMB 300,000.†Wang Wei pointed out that “similar cars produced by other companies will be difficult to compete with Toyota.â€
As for Tesla, "his design, packaging of technical concepts, can not be learned by others; and even if the existing patents are open, Tesla has enough strength to develop more leading technology."
Many companies can see that Toyota and Tesla are plotting to use more companies to promote the infrastructure of new energy vehicles. Toyota and Tesla are likely to be the ultimate beneficiaries. This is their conspiracy.
But it is also necessary to point out that whether these two patents can help them achieve their goals is not known. Chen Wenkai believes: "The most fundamental problem now is that the battery technology is not mature enough to meet the needs of users. Before this problem is fundamentally resolved, social capital will not be swayed and the basic package will not be solved."
Based on the size and types of heating elements in the car seat, the heating process can be faster or slower. There are seats that have carbon fiber heating wires whereas some have been equipped with NiCr heating wires. You need to get a unit that offers quick heating and able to evenly distribute the heat all over the seat for a warm and soothing feeling.
