Sequel hydrogen fuel cell vehicles

The world's longest continued driving mileage hydrogen fuel cell vehicles Sequel Shanghai Auto Show debut laptop battery, acer batteries.

From the Shanghai International Auto Show held at the time of the month, General Motors could not wait to Chinese companies in Shanghai, announced the results of its latest R & D - Sequel hydrogen fuel cell vehicles will be unveiled this year's auto show. It was just the beginning of the year the car show in North America show that the first shock of global industry and this show will be known as "the highest scientific and technological content of the show car."

It is understood, Sequel of a new generation of fuel cell system to the previous generation fuel cell device components to be simplified, so that significantly reduce manufacturing costs, the maximum power increased by about 25%. Sequel to benefit from the outstanding performance of hydrogen storage capacity increases, the previous GM R & D and will be carried out in Shanghai this year, running the model "HydroGen III" as compared to full storage pressure doubled. GM China, said Chen, vice president, Sequel is a General Motors fuel cell vehicles to the commercial production of the target as an important step.

In fact, the general hope that by showing such strength to win the Government's concern and support for the next decade the development of GM in China and lay a good foundation. China has become the global status of GM and Toyota run an important market. Toyota has taken the lead in the Prius hybrid sedan in China to get the case of production, fuel cell cars have become common in China under a key point of development, after all, the need for two sets of hybrid engines and the high cost compared to fuel cell vehicle the price of the plan in general is fully competitive, and China is the world's most likely a hydrogen fuel cell vehicle development areas, and to the general push for mass production of fuel cell vehicles in 2010, China will become a global car demand the greatest place to load hp pavilion zv5000 battery. Then, in environmental protection and energy saving advantages are the prospects for fuel cell vehicles are limitless.

However, although the idea of better, but the competition is not too easy to imagine. Although common at all costs this year will be "HydroGen III" to get to Shanghai model run, but the general partners - SAIC Group and Tongji University developed "Beyond III" will have 10 cars at the end of the road in demonstration run. It can be said that not only faced with common transnational auto giant Toyota's step-by-step pressure, is also facing domestic automobile companies and R & D challenges.

Nevertheless, it is hardly surprising that GM spent the past two years been great efforts to promote its own hydrogen fuel cell vehicles in the achievements. The industry believes that, as the hydrogen fuel cell vehicle is a new product, so there is not a mature domestic technical standards, and domestic and foreign enterprises to the development of these standards in the relevant departments can make their voices heard, but also to maximize the safeguarding their own interests. It is learned that the three countries in Japan and the United States car companies have hybrid vehicles on the domestic technical standards in a competition.

In that case, GM would like the issue of whether what kind of sound? GM hydrogen fuel production car How far the road? A few days ago, our reporter had an interview with GM's design and technical integration of the Department Director and Project Director of Se-quel Dr..

As safe with the traditional car

Oriental Morning Post: As the hydrogen is the fuel, people will often linked with the explosion, especially in a moving vehicle will inevitably encounter in the course of severe impact, then how security Sequel?

Chris: security is the most common issues to consider, at least as safe and conventional diesel, in fact, we designed the safety of hydrogen storage tank fuel tank than the traditional strong many times also. We are the standards adopted by national standards than we are even more stringent 20%. The test includes the hydrogen storage tank set on fire in burn, fall down from the high-altitude, fast cut, shooting a gun, the conclusion of these tests: You can use in different countries.

Oriental Morning Post: hydrogen fuel cell vehicle hydrogen how to check system?

Chris: There are many sources of hydrogen, such as natural gas, solar energy, wind energy, nuclear energy.

Oriental Morning Post: GM believes that the most suitable for the development of China's energy which car?

Chris: China must be more than one kinds of energy sources and countries acer lcbtp03003 battery, acer travelmate 4000 battery.

Hybrid is only a transitional

Oriental Morning Post: At present, many manufacturers have committed to the promotion of hybrid, may I ask what the current GM hybrid products?

Chris: At present, the major general for the development of hybrid truck, there are currently more than 300 in Seattle buses running in the model, hybrid Chevrolet pickup sales in the United States. However, due to use two sets of hybrid engines, so the high cost of foreign governments for environmental considerations to the purchaser will normally be a certain amount of subsidy and the manufacturer. For example, in the United States, consumers purchase a hybrid can get 30% tax rebate equivalent to 1200 U.S. dollars. GM is expected by 2007 will launch a hybrid car.

Oriental Morning Post: Toyota has decided to domestic production of hybrid cars, GM will introduce hybrids in China do?

Chris: As to when the domestic launch of hybrid cars, not in accordance with common practice will not be clear before the public. But the need to point out that hybrids still need oil and can not fundamentally solve the energy and environmental protection issues, can only be described as an interim measure.

5 years after the price of 20,000 U.S. dollars

Oriental Morning Post: GM in 2010 is expected to enable volume production of hydrogen fuel cell vehicles, and diesel prices as the present, I do not know what the current stage of development?

Chris: GM's ultimate goal is the cost per kilowatt of power is 50 U.S. dollars, a better car is the power of 100 kilowatts. At present, the traditional diesel power cost per kilowatt is 30 ~ 70 U.S. dollars. Under normal circumstances, power and transmission prices account for vehicle 1 / 4, which is our goal of hydrogen fuel cell vehicle power and transmission prices around 5000 U.S. dollars, the price of the entire vehicle in about 20,000 U.S. dollars, with the current traditional internal combustion engine basically the same price. However, the cost is still expensive, we challenge is the cost and increase battery durability and reliability. Our goal of fuel cell life span is 5500 hours, from a technical rather than talk about the challenges, the key is to reduce costs and simplify the design.

Oriental Morning Post: hydrogen fuel cell vehicles to reduce the cost of the current problems in which the largest?

Chris: in terms of specific problems, first of all, the current production of fuel cell cars are all manual, not the assembly line production. Such as fuel cells through artificial pieces are connected together. However, artificial production was not the main problem, another problem is that hydrogen pumps, compressors to reduce the costs of the sources of carbon fiber acer travelmate 3000 battery, the source of proton exchange mode, but proton exchange mode when not in small batch production will be down, to reach the million, 10 million of production costs can be decreased.

"China made" uncertain

Oriental Morning Post: GM used to think that China is the United States outside California are most likely to develop hydrogen fuel cell area, then the GM hydrogen fuel cell vehicles will get the Chinese to produce it?

Chris: Over the past two years China's oil consumption growth is mostly due to motor vehicles, therefore, the issue of energy saving and environmental protection of motor vehicles have been taken seriously, the new auto industry policy has been clearly put forward to encourage the development of energy saving and environmental protection vehicles. Petrol filling stations in China are also popular, but not abroad, and therefore the promotion of hydrogen energy vehicles are relatively easy. However, despite the fact that China is the most likely development of hydrogen fuel cell vehicles, but GM's hydrogen fuel cell vehicles is still to get the Chinese to produce depends on the use of the cost of hydrogen production, as well as the Government, energy suppliers, automobile companies, zero parts suppliers and other factors.

Environmental protection, lasting into the new direction of the development of notebook batteries

With the use of mobile office continually increasing demands from the requirements of the performance of notebook battery computers is also increasing. Notebook computers as opposed to desktop, and its advantage lies in its portability and mobility. If you give up the battery and was renamed as the "Mobile PC", now the notebook does not disappear it? From the mainstream of the development notebook, the ibm battery technology development is essential and has become extremely important.

Now, the real development restrictions notebook hardware configuration is not the biggest factor, but continuous battery power supply and environmental issues. Intel Corporation Commissioner also said with emotion, "ten, nine users of notebook battery power supply time continuing dissatisfaction with the battery can supply the requirements of mobile users to use a longer time. And chips, memory, display devices and even the speed of technological development has been greatly advance the development of battery technology. "From this we can see that the battery for the notebook computer products, has an extremely important role in the characterization.

Notebook battery nickel-cadmium have experienced the era of era of nickel-metal hydride, lithium-ion era, although the notebook battery technology with a certain degree of development, various types of lithium batteries used in notebook long in 2 ~ 4 hours, but still fundamentally did not solve the problem. If you only rely on the increase in the capacity of the battery to increase battery life. Under the conditions of the existing technology can only increase the battery size and weight of its own. If this is done according to, can not be products of existing ultra-thin notebook, ultra-light design concept is acceptable, but will not be accepted by consumers. Thus, the major notebook manufacturers to think about how the brains of the notebook battery to solve the "environmental protection, and lasting" problem.

As early as 1839, the British W Grove reaction on hydrogen and oxygen can be made of the principle of power generation, in fact, this is the first hydrogen - oxygen fuel cell. 60 but it was not until the early 20th century, due to the needs of aerospace and defense, before the development of small-scale liquid hydrogen and liquid oxygen fuel cells, used in space flight and submarine in the area. The development of recent decades, due to a lack of energy and environmental protection of the outstanding requirements of human beings must be the development and utilization of new clean renewable energy, to make up for the shortage of resources and pollution problems. Fuel cell energy conversion efficiency due to high environmental pollution by the advantages of small universal attention.

Assistant U.S. fossil energy said: "The fuel cell technology in the 21st century, half of the impact of the technical, would be similar to half of the 20th century, the role of the internal combustion engine." Ford Motor Company manager in charge of PNGV said, "fuel cells will certainly bring about a revolution in automotive power, fuel cells both at the same time is the only non-polluting, efficient, widely applicable, without noise and with continuous work and the building blocks of the power plant. "

Both the non-polluting fuel cells, efficient, widely applicable, without the noise and the advantages of continuous work. And a by-product of fuel cell work is only water and heat, non-polluting, high efficiency, is a clean environmentally friendly power. Compared to commonly used lithium batteries and polymer lithium battery to clean, environmentally-friendly. And fuel cell has a higher energy density, in the same capacity to do a smaller battery, or the same volume and weight of battery, the battery capacity to do more!

In the portable device to replace lithium battery micro fuel cell is in progress. In the field of fuel cell most of the leading companies in Japan. The global consumer electronics giants such as Hitachi, NEC and Toshiba and other companies in the field of micro fuel cell has been in a leading position. In the United States, MTI Micro Fuel Cells, Medis Technologies, Inc. and a few other companies are actively developing micro fuel cell. These companies play an existing industrial advantages ibm thinkpad r60e battery, ibm thinkpad t60 battery, are the first generation of production to the commercialization of micro fuel cell-powered equipment. Them in the development of smaller, lighter, power and more reliable micro fuel cell has achieved fruitful results.

NEC's latest prototype fuel cell for an average output power of 14W, maximum output power of 24W, voltage of 12V, the battery of the total weight of 900 grams, the weight of fuel for 300 grams. Fuel cell size for the 270 × 270 × 40mm. When the fuel concentration is about 10% of the 300 cubic centimeters of methanol, the notebook PC can run about five hours. Fujitsu Research Institute of the well-known publication for their R & D of fuel cell laptop. Maximum power output of 15W, the use of 300ml of methanol solution as fuel, they can drive the company's notebook computer "FMV-BIBLO MG55E" continued to run from 8 to 10 hours.

However, fuel cells widely used in notebook computers also need to address some practical issues:

The cost is too high. At present, the fuel cell to generate hydrogen at low temperatures required for the cost of platinum catalyst is more expensive, and its low power density. Compared to the overall cost can not be compared, such as lithium batteries.

Fuel supply. Fuel cell and we use the lithium batteries used are different fuel cell is not charged, it is necessary to continue to supply electric power, can only add fuel (electrolyte) method, how to allow users easy access to these fuels, there is a certain degree of difficulty.

Start a matter of time. Fuel cells need a warm-up time to meet our power requirements.

Output problem. Fuel cell in the use of the process it can not provide a very stable output, the middle of a certain stage there will be a significant slowdown.

It is evident from the fuel cell in the notebook computer you want to be widely used also in need of further research and development, but we believe that the prospects for fuel cells is very bright, as low pollution, high energy density products, which notebook computer's battery for the continued ability to portray a bright future. At present the efforts of companies, fuel cell in the notebook computer application technology has been rapidly improved. Believe that in the next few years is expected products, and practical use. At present, the industry generally felt that the early fuel cell generally can provide 6 to 8 hours of power time, as the technology matures, to reach a longer period of time is bound to occur.

Current cell phone battery you have damaged the General Assembly?

A consumer Gome store in the 6688 Siemens mobile phone. Purchase mobile phones, equipped with two batteries, one thin one thick and thin is the original battery, domestic battery is thick. After the purchase of two battery can maintain for about two days standby time. But three months later, the phone battery can only maintain one days of standby time or less. I tested to the repair shop, was told that as a result of mobile phone emission current is too large, resulting in shortened battery life, they were replaced a motherboard. But came back, I found that mobile phone battery standby time is still very short, and can not charge, I called the repair shop, was told that the phone battery is bad, can not be used, and this time also had 6 months battery warranty.

The consumers want to know whether it was due to excessive emission current mobile phone, resulting in damage to cell phone batteries.

Journalists access to relevant information found, a qualified cell phone batteries, should not be too large as a result of current was damaged, but the current is indeed too much power loss would result in larger cell phones, the battery standby time shorter.

A standard cell phone 346970-001 battery, hstnn-db02 battery performance should be as follows: state life cycle of mobile phone batteries should be more than 300, the industry is even more stringent requirements in the life --- more than 500. Rated battery capacity should not be less than the standard size of 95% and full power to place 28 days, the minimum capacity of not less than 60% of rated capacity; phones internal battery should be over-current protection device, such as lead in the external short-circuit current situation is too large automatically cut off the circuit, so as to avoid burning or damage to mobile phones; lithium-ion batteries have been sufficient to protect the other lines, when using non-standard electrical appliances, paying too much electrical current will automatically cut off when the power does not lead to charge into the battery under normal circumstances automatically return to the conduction state; mobile phone batteries should be an internal temperature sensor, battery charger for charging to provide temperature signals to control the charging end.

As the mobile phone in an instant boot, standby mode, as well as the launch of the current state is not the same, so instructions can be by observing the ammeter to determine fault. Phone connected to DC power supply, according to the boot when the observation of key regulators ammeter source. By the boot keys, the ammeter pointer reach full partial moment, power shutdown protection. This situation is the phenomenon of mobile phones there are short-circuit caused by leakage or filter capacitor. Normal boot should be around the moment the current of about 200mA, standby current of about 50 ~ 100mA or so, and the pointer kept swinging, launching around 300mA current from the standby to launch a jump.

Stickers to make the battery "Zengshou"

Doubt the existence of three laptop battery: the product name are not unified, anonymous production dell battery, excessive price fluctuations

About two years ago, the market began to appear claiming to be a kind of extended battery life for mobile technology-based new products, for a time aroused the concern of many consumers. The product is available now, it seems that very few users of this "new product" will always remain in the main mail-order and online channels for marketing on the road.

Reporters in the major mobile phone sales counters at the scene of the annex, have not found a trace of this product. Subsequently, the reporters contacted by phone the voice of a significant rally in the online "magic battery energy paste" agents of the central zone, according to the Wuhan Miss Li introduced, the product could be applied to mobile phones, notebook computers, lithium battery of any incidental, very good feedback effects, this product is priced in Wuhan region is 38 million, for mail-order, then to Beijing will certainly be much higher prices, Miss Li explained, "This is the level of consumption by the regional differences in the decision." A reporter asked about the product from any company, Miss Li said only they are a company in Shenzhen Central District Deputy, which is produced by the Shenzhen technology products, as the company's name and contact information that can not be disclosed.

Although similar, and to the north of Tianjin technology market, this wonderful product and a pseudonym for "battery chip recovery." Agent responsible for the product's Wang told reporters that their distribution of "the restoration of cell-chip" is the original product in Japan and has been patented in Japan. Mobile phone battery patch loaded after 3 to 4 times after charging, the effect will gradually surfacing. If it is very old model of the battery, talk time can be increased by 30% to 50%, and the new battery life can be nearly doubled. Wang said the product is currently used primarily as a bundled package to the mobile phone products distributors, is also the main brand for Samsung cell phone. The engineers claimed to have repeatedly stressed that no mandatory certification requirements, but the vital interests of consumers based on considerations such as product safety is still carried out the full argument, so that the product Measurement of Chinese Academy of Sciences, through the quality certification and Tianjin City Communications Products Quality Supervision, Inspection and stop the relevant certification. Making similar products for some of the "absorption of electromagnetic waves mobile phones" propaganda signboards, Wang denied the rumors.

Lack of norms, not the name of unity dell inspiron b130 battery, dell latitude 120l battery

According to a mail-order and the use of such products, Miss Guan said, "posted on the phone for nearly six months, and did not see any effect." Experts have said that the role of the principle of this product appears to be convincing, in fact, not very scientific, with the obvious propaganda exaggerated. However, although the effect is not ideal, because of its hazards to humans does not exist, the State General Administration of Quality Supervision, Inspection and Quarantine Treatment Center product quality related complaints have also told reporters that "At present, such products have not yet accepted the complaint."

According to Chinese Academy of Sciences, car, introduced measures for these products can do so far for the safety certification, and other product features can not accurately define the role of all the publicity of products are oral argument. In fact, such applications have not reached a mature level, the standard is not perfect, the relevant departments is usually based on market feedback after the consumers, product quality, efficacy and the audience and other factors to determine the development of industry testing standards or enterprise standards related issues. At present, such a variety of mobile phone batteries, "the recovery of the film", "power paste", "power paste" and so on, in the market has not been fully recognized, the actual effectiveness of the yet to be inspected, due to the lack of a clear threshold for access system, manufacturers and agents in the promotion and sale of products, there are obvious chaos.

Scientific perspective to examine mobile phone batteries

The size of the battery capacity of a cell phone for example, is one of essential criteria. Charge capacity, and cell phone standby time and talk time was significantly longer on; the capacity of small, then standby, talk time is relatively shortened. Standby time, talk time is a relative concept, to examine the capacity of the battery to consumers should be viewed in terms of integrated time, that is, standby, talk time at the same time. Simply put, the battery's rated capacity should not be less than 95% of the standard size, full power to place 28 days, the minimum capacity of not less than 60% of rated capacity, battery life of not less than 400.

"Foreign experts" to Changhsingian lectures organized by industrial battery
