Tesla and Toyota: Fuel Cells Compete for New Energy Future! ?


TESLA motor

Recently, the car manufacturer Toyota Motor Corporation ("Toyota") announced that as a facilitator of fuel cell vehicles (FCV) measures the popularity of the free offer unique about 5680 Toyota fuel cell related patents (including pending patent) the right to use.

This is not the first time the auto companies a free open patented technology in the new energy sector. In June 2014, Tesla had offered to open up all the patented technology to promote the development of electric vehicles in the industry. Toyota and Tesla technology companies are towards the throne of the world's new energy vehicle chief attack from different paths. The two companies in the field of new energy vehicles and more concentrated smell of gunpowder, are trying to open the way for more allies and accelerate the pace of development.

Tesla and Toyota: fuel cells compete for new energy future! ?

To work together to promote open and generous

FCV enter the market in the early stages, in order to give priority to popularize related technology as a starting point, Toyota believes and is committed to the development and the implementation of FCV commercialization of the automobile manufacturers, as well as be responsible for the construction of hydrogen refueling stations and other energy companies to work together to carry out the popularity particularly important. Based on this, Toyota decided in the early market introduction (expected until the end of 2020), to provide free fuel cell stack, high-pressure hydrogen storage tank, a fuel cell control system, the right to use the patent. In addition, to promote the popularization of hydrogen refueling stations as soon as possible, provided free of charge indefinitely manufacture, supply hydrogen hydrogen station patent rights.

On the use of these patents, and the general procedure to obtain the right to use the same patent, Toyota needs to apply to individually negotiated and signed the contract after the specific use conditions. Toyota spokesman Niu Yu China to accept the "First Financial Daily" reporters spoke fuel cell vehicle technology and Toyota's hybrid vehicle technology is the same strain, hybrid core technology sharing and in electrical, electronic control and other aspects, Mirai the project design team have come from hybrid automotive design engineer. After years of development, Toyota's hybrid technology has been very mature, has global sales of more than 7 million hybrid vehicles, fuel cell vehicles, but due to aspects related to the construction of infrastructure facilities, the popularity of many relatively high degree of difficulty alone, Toyota, a company limited power , the open-related patents, and hope that other car companies and other enterprises to jointly promote energy.

Earlier, Toyota hybrid car technology accused of relatively "stingy." Toyota repeatedly in China's new energy vehicles a series of positive incentives "off the list", the industry believes it has a great relationship with Toyota in the non-plug-in hybrid technology is not open to form Solidago dominate. Toyota hybrid joint venture in China, the United States Bureau of the battery business because even touch the Chinese Ministry of Commerce, "antitrust" and phenomena relevant provisions of twists and turns. Last July, the Chinese Ministry of Commerce issued the "Notice on additional restrictive conditions approved by Keli far, Toyota China, PEVE, the new source, Toyota Tsusho intends to set up a joint venture focused on the case of operators antitrust review of the decision." (Ministry of Commerce 2014 No. 49) that the additional restrictive conditions approved by the Ministry of Commerce, one of the conditions is that the United States Bureau of production should be realized after three years, foreign sales of the product.

For Toyota, the so "generous" open fuel cell-related patent rights, automotive analyst Zhang Zhiyong talked about in the "First Financial Daily" reporters, Toyota's strategy changes, there is significant progress in terms of business thinking, etc. alone to drive a Toyota fuel cell vehicles, the difficulty and the pressure is very large, and therefore need to pull into more business and capital to join the camp, in order to accelerate the pace of development.

It is said that in the early development of the Toyota hybrid car, has continued to burn more than a decade began to realize a profit, while Toyota has yet to officially respond to this official. Zhang Zhiyong comes to fuel cell vehicles is the ultimate goal of the new energy vehicles, hybrid technology is more complex than the technology, the greater the difficulty, the world's other car companies are basically no substantial development in fuel cell vehicles, Toyota put even open 5,000 patents rights, other car companies in a short time is difficult to catch up with Toyota, Toyota Moreover, this does not indicate that all the release of the fuel cell patent rights, may also hold the hands of some of the core patents.

Niu Yu stressed that Toyota has always been open to technical style, there was cooperation in hybrid technology with Mazda, Ford and other car companies too, no matter how good the technology is of little significance if not universal, the further expansion of gratis patent use rights. Niu Yu mentioned, Toyota's patents in three, one is free to use, one is paid to use, there is a patent is limited to internal use.

Tesla and Toyota: fuel cells compete for new energy future! ?

Inevitable contest

On January 15, Toyota officially on sale in Japan named "Future (Mirai)" The four-seater fuel cell car. The car is priced at 7.236 million yen (about 400,000 yuan). The Japanese government will subsidize 2.02 million yen per vehicle, consumers only need to pay about 5.2 million yen (about 270,000 yuan).

Toyota originally planned 2015 sales in Japan 400, 300 overseas export of fuel cell vehicles, mainly to the United States and Europe. But Japan has received orders for more than 1,000 vehicles, according to the current production rate, subscribers need to wait a year to two years to put the car. To meet consumer demand as soon as possible, Toyota has decided to invest an additional 20 billion yen, an additional two production lines, production capacity will soon be expanded to the current three.

FCV is performed by electrical energy generated by the chemical reaction of hydrogen and oxygen driven. Mirai just listed this fuel cell vehicles to fill a tank of hydrogen just three minutes after fill the fuel can travel 650 kilometers or more in a row, no less than the life of traditional fossil-fuel vehicles, fuel costs and gasoline costs required quite.

Fuel cell vehicles due to their high energy conversion efficiency, completely non-polluting emissions and a more convenient and efficient use of the conditions has long been considered the ultimate direction of the development of new energy vehicles. However, after due to the high cost of fuel cells, has not been able to popularize. China Automobile Dealers Association executive director Jia Xinguang Expert Committee to accept the "First Financial Daily" reporters when he talked about hydrogen cars 10 years ago cost $ 2 million, and now the cost is reduced to about 1/30 of the original, less than $ 70,000, may Bitesila more competitive.

The 8th anniversary of the birth of Iphone: interpretations of what is real innovation

This year's CES show has released a lot of new products, but people should remember that a real change in the world of what the product is. Eight years ago, Steve Jobs (Steve Jobs) in Los Angeles issued a first-generation iPhone, which indicates that the rise of the PC's death and smartphones

iPhone more popular it? In 2006, that is, the year before the launch of iPhone, Apple's full-year revenue of 19.3 billion dollars, which is the sum of all Apple products revenue. And last week, the technology blog Gigaom founder ohm Malik (Om Malik) said, UBS Investment Research expects fourth quarter 2014, sales on the iPhone alone generated more than 43 billion US dollars in revenue. For comparison, the chip maker Intel's sales in 2014 are expected to only $ 55 billion. Network equipment giant Cisco reported fiscal 2014 revenue of only $ 47 billion.

Since the iPhone and its many imitators seize the consumer electronics market, sales of the injured is not just PC, TV's in decline, sales of camera in decline. After the smartphone can achieve most of the functionality of these products, other electronic products have become less important.

At the same time, the whole world are connected iPhone smartphone inseparable established norms. No there is no taxi iPhone application Uber. In a world where there is no smart phone, Facebook is still just a PC-based browser service, who was used as an office all day diary tool. Twitter messages can only be a tool to tell a friend where you are. Also be able to remain king of the World Wide Web.

But the fact is that Apple recently said that Apple's App Store has come up more than 10 billion US dollars in revenue back to the application developer. According to market share, Google Android is now perhaps the world's largest mobile operating system, but allows developers to earn income in this regard, Apple has established a goal of catching Android.

Apple's Steve Jobs has been around during the appearance of the first generation iPhone to make a fuss, and gradually improve the allocation in an effort to better it. Larger screen iPhone 6 Plus subvert all this, it is no longer widely regarded as a big step forward. Even if there is no progress, but Apple's predicament highlights what kind of things are eligible to be called innovation, this word has been abused in the technology industry, but with the iPhone body is deserved. If there is no iPhone, 2015 year we may still use the Sidekick and Treo phone

Secret Comprehensive Mobile Power Internal Circuit Protection Design

Today, the power consumption of smart phones is growing, most of the smart phone battery is not removable, a large-capacity portable mobile power people to travel has become essential electronic products. But recently moved out of the power of frequent accidents, so that consumers and engineers to rethink the design and development of mobile power, and for the internal structure of the mobile power, you have to know how much?  


Now smartphone power consumption is growing, most of the smart phone battery is not removable, a large capacity portable mobile power people to travel has become essential electronic products. But recently moved out of the power of frequent accidents, so that consumers and engineers to rethink the design and development of mobile power, and for the internal structure of the mobile power, you have to know how much? Usually consists of a mobile power shell, batteries and proctection circuit boards. Shell is mainly product package, and achieve attractive appearance, protection and so on, common for plastic and metal, some plastic products are often applauded also used fire retardant materials. Board is mainly used for voltage and current control, input and output control, and other features. Mobile power batteries are the most costly part of the 18650 and lithium polymer batteries are the two most common. Aside from batteries, mobile power supply circuit board is also very important. For rechargeable batteries, charging specifications have security and safety cut-off voltage discharge cut-off voltage, there is calibrated rated maximum operating current. Mobile power supply design, the first to be safe polymer battery, because the battery cost is relatively high, and in order to secure reliable operation of the system, there must be a charge management system. When you need to charge portable devices, polymer external battery discharge, because the portable device universal input voltage of 5V, so there is a boost 5V system. Whether charging management system or booster systems are required to provide the board, so moving the internal power supply circuit board designed to determine the quality of the product or not smart.

1. Lithium battery overcharge protection overcharge protection is to detect voltage power management chip implementation, chip set at the reference state (cell phone lithium battery typically 3.5V). When the benchmark rises slowly when rising to VSS-VDD design value, the voltage at this time is to protect overcharge off voltage, by logic low or high output to control external control circuit to achieve overcharge protection. Set VSS-VDD voltage value when the voltage slowly drop to a reference value when the reference is detected at the time of setting the following, which is the logical relationship lift overcharge protection.

2. Over-discharge protection over-discharge protection voltage is the protection of the battery discharge transition lowest voltage to the voltage at the point when the discharge protection circuit cut off the circuit, to protect the battery purposes. Battery life based on the relationship with the depth of discharge and battery voltage and discharge rate and depth of discharge relationship, combined with the actual load equipment to determine the battery discharge voltage, battery discharge protection circuit design.

3. Short circuit protection Short circuit current is generally caused by more than 10 times the rated current, and over-current protection requires a delay of about tens of milliseconds, the number of times the rated current is directly caused by a short circuit within tens of milliseconds, the battery pack will also performance impact. Existing methods are PPTC protection, the method is the heat generated by the current cut off the circuit, also requires millisecond response time, while increasing the loop impedance. There is also dedicated to short-circuit the battery pack integrated chip, this chip narrow range of applications, the high cost.

 

4.PTC introduce PTC positive temperature coefficient thermistor, also known polyswitch, polymer resettable fuse (polymer resettable fuse) polymer resettable fuse from the polymer matrix and to make it conductive carbon black particles. Since the polymer resettable fuse for the conductor, on which there will be current. When there have been heat (as I2R) current through the polymer resettable fuse, the resulting expansion will make it. So as to separate the carbon black particles, polymer resettable fuse resistance will rise. This will lead to faster polymer resettable fuse produce thermal expansion larger, further increases the resistance. When the temperature reaches 125 ° C, the resistance varies significantly, so that the current significantly reduced. At this flowing polymer resettable fuse small current is sufficient to keep it at this temperature and in a high impedance state. When the fault is cleared, the polymer resettable fuse shrink to its original shape again link up the carbon black particles, thereby reducing the resistance to keep current with specified this level. Understanding of mobile power inside the main components, how do we choose a high-quality mobile power it?

China 2015 mass production of graphene lithium or subvert the electric car industry

December 26, 2014, the US electric carmaker Tesla released an updated version of the discontinued two years ago, the first generation model Roadster, the mileage of 644 km, 60% higher than the original.
 
Advances in battery technology to enhance the performance of the Tesla product, after Roadster Mileage is 393 km. Tesla CEO Musk said Tesla high-performance graphene battery, compared to the current capacity increase of nearly 70 percent.
British scientists have invented graphene after 10 years, the application of the battery with great breakthrough. In early December, the Western media reported that Spain and the Spanish company Graphenano Cordoba University to develop graphene battery, a charging time of just eight minutes, can travel 1000 km. It is graphene researchers called "super cell."
"We still understand the situation, the specific situation in Spain is proving such a battery, if this is confirmed, it is indeed a revolutionary change out." China graphene industry technology strategic alliance Secretary-General Li Yichun said.
Spain's "super cell" will soon be used in the same car as the Tesla, according to Western media reports, its owner in December to test the two German auto giant cars, and production in the first quarter of 2015 Listed use.
Charging time close to refuel graphene
Currently, the global automotive battery manufacturers use lithium batteries are mainly used to Tesla [microblogging] represented by nickel-cobalt-aluminum lithium batteries (lithium cobalt oxide battery), represented by BYD lithium iron phosphate and to Japanese automakers as the representative of manganese lithium batteries.
These three types of battery with the highest energy density of lithium cobalt oxide, but it is also the most unstable at high temperatures; lithium iron phosphate, the most stable, but the lowest energy density.
Lithium-ion battery technology has been quiet for 20 years without major technical innovations. A study of battery power, experts say, the biggest obstacle is the limited power density lithium-ion battery, it can not quickly receive large amounts of energy or release.
Tesla uses an upgraded version of Roadster3.0 had improved lithium battery, Tesla did not confirm whether or not to join the graphene. However, its performance has greatly improved, I am afraid only of graphene can do. The new and improved lithium battery capacity 18650 significantly increased, the number 6831 of the battery pack does not increase, the total capacity of the battery pack from 53kWh increased to 70kWh.
According to interviewed experts, graphene structures can change the long-term there is no breakthrough in battery technology barriers. The internal structure of the graphene sheet interval extended to allow more electrolyte "wetting" and a lithium ion battery performance of a lithium ion to obtain a high rate channel.
"Graphene is characterized by conducting fast, good conductivity, many studies are currently in the experiment, it is difficult to say exactly which one, but shorten the charging time is for sure." Li Yichun said. According to the United States is expected to Rensselaer Polytechnic Institute researchers, graphene anode material charge or discharge 10 times faster than today's lithium-ion battery in a conventional graphite anode.
According to the data of these institutions in Spain, graphene has the potential to significantly increase the capacity of the battery. "Super Battery" parameter display, the energy density of more than 600wh / kg, is five times the power lithium battery; lithium battery life is doubled; it costs 77% lower than the current lithium batteries.
Lithium traditional manufacturing powerhouse, Japan and South Korea, in the graphene battery technology they are to snatch the initiative, South Korean scientists as early as last November announced graphene super phone battery latest invention, can store the same amount of conventional batteries power, but the charging time of just 16 seconds.
Japan implemented in two lines parallel battery technology, in addition to the development of lithium batteries in the ordinary sense, they also studied the fuel cell technology, an alternative material graphene with a special platinum as a catalyst, to produce hydrogen fuel cell vehicle fuel required to obtain breakthrough.
According to Li Yichun, the current points total of graphene research on two: one for application in traditional lithium batteries, the purpose is to improve and enhance the performance of lithium batteries, these batteries do not have disruptive effects; the second is based on graphene create a new system battery, which is a new series, the performance is subversive, known as "super cell."
China 2015 mass production of graphene lithium battery
The promotion of new energy vehicles, up to five years, but the effect is not ideal. According to the Ministry of Industry statistics show that 11 months of 2014, cumulative production of new energy vehicles 56700, and 2015 pure electric vehicles and plug-in hybrid car production and sales goals and strive to reach a total of 500,000 of the gap is huge.
The main reason is that the market difficult to use the convenient degree: First lower the mileage, consumers generally have range anxiety; the second is charging facilities inadequate, charging inconvenient affect use.
In traditional solutions, car prices to promote the use of hybrid mileage relieve anxiety, oil or electricity consumers can choose according to the actual situation; another perspective, the state encourages large-scale construction of the charging station and charging pile, charging ease difficult.
Graphene super battery occurs, it may completely change the existing charging problem. Mileage doubled, long-distance travel mileage anxiety may completely broken. Spanish super battery, for example, almost 1000 km Mileage approaching a straight line from Shanghai to Beijing, far beyond traditional driving distance of a tank of fuel in the car.
Graphene charge faster, you can reduce the charging time, can reduce the charging station and charge a wide range of macro-demand pile. In the current global leader ModelS85 Tesla, for example, through the power of its super charging station, have 80 minutes to full, the owner, such as charging time is still an ordeal.
"Super battery 10 minutes of charging time, longer than the first oil plus a little bit of time, but the mileage than a box of oil much longer, consumers never complain." A car industry analysts said.
Currently, hybrid cars are considered to be the best product on the market for the transition from fuel vehicles to electric vehicles, and this transition period may last up to 15-20 years, but advances in battery materials could overthrow this anticipation, Even the popularity of electric cars may not need that long.
"Super cell" Once applied to large-scale electric car, the entire industry will be disruptive. "Some hundred car prices may not have the technology and the decline, and some only ten or twenty years of car prices, because the master new material technology, could become the new giant."
Li Yichun, said the current domestic battery graphene research progress on smoothly, some universities and R & D team in Shenzhen enterprises to cooperate, research has entered the pilot phase, "the first half of 2015 it is possible to mass production, the performance will be a lot upgrade, such as without increasing the amount of cost in the premise, to increase the number of charging and discharging lithium, and the like to improve the battery safety. "
China graphene industry technology strategic alliance in 2013 had been reported to the national ministries of multiple graphene research bases, Wuxi, Chongqing, Nanjing, Qingdao, Changzhou, etc. have established graphene industry demonstration base. December 2014, Chinese President Xi Jinping visits the high-tech industries in Jiangsu Research Institute, the research and development of graphene visit Products.
However, according to graphene cell research said that the current study is the major domestic graphene applied to the lithium battery, rather than a new system of "super batteries", so the domestic technology and super batteries have a certain gap. The relevant state departments this very seriously, in 2015 introduced the "Thirteen Five" plan new material graphene may be included.
