Digital battery

Toshiba has been engaged in developing portable fuel batteries, although in a few months before the products of trial exposure open, but they have still not been put into production. Not long ago, Toshiba has finally made the decision to the fuel PA3383U-1BRS battery market. Stacks of security as the most important uses a large quantity of stainless steel and aluminum and other metal parts. This document will include fuel batteries and development of portable products, technical advice, analysis of new products.

 

“People see a single list itself” (portable personal technology products). Toshiba by the end of October 2009 announcement of the 3000 limited edition battery phones fuel “Dynario. Crisis on the market for fuel battery, phones and staff the fuel battery technology are issued with wonder and gratitude for the vote.

 

After the introduction of the battery, a number of developers of fuel batteries immediately resumed multi-block and carry out audit work. Words such as “From the entrance of moisture is constant and smell the methanol fuel and so on, can feel a high degree of completion of the battery,” “Even if only the measuring the temperature of bath water, but heat is still a cause for concern, “and so on, all kinds of reactions are very rapid after another. We also bought a PA3395U-1BRS battery newly listed fuel and to analyze characteristic. And Toshiba, with help from the public an internal component.

 

In fact, more than 30,000 yen?

 

Dynario is a fuel battery direct methanol (DMFC). Able to use the terminal as a portable USB charger. With the built-in lithium-ion rechargeable battery set, the maximum power of 2W (5V, 400mA). The batteries can be injected in 14ml of methanol. Use of fuel “may be portable so full of 2″ (Toshiba). We use 1W power consumption of LED lights to confirm the results show that sustainable power generation to 11 hours or so, one in the new generation can be estimated at about 11Wh.

 

Fuel battery from Toshiba can be recharged via USB for portable products. The fuel use of 50 mL bottle filled with fuel. Dynario sells ¥ 29,800 including tax. As a battery charger external point of view, the price dearly. Toshiba said that “the price is higher because the specialized multi-component system leads to the high costs, while the actual removal process, it is surprising to many parts was beyond the imagination (Figure 2). This is due to the PA3399U-1BAS battery by adding a large number of ultra-small pumps and valves, MCU (microcontroller) and IC control, control of speech and if the circuit Outside the components of fuel batteries. In addition, starting on the outside metal and reinforcement of the shell composition is also too high. Most Portable and industrial fuel batteries, the developer, said: “Given the account component and manufacturing costs, ¥ 30,000 is really not enough.” There are two units of energy, fit two sides. In addition to generating part of the NMR systems, generation of control components and parts used to ensure robustness as much attention.

 

Fuel cock laboriously

 

Dynario the basic elements - both inside and outside the central part of the shell to configure a unit of electricity. In addition, the center speaker is also equipped with Sanyo Electric produces cylinder-type lithium ion rechargeable batteries and two to install the power switch and input terminals and output to control floor. The fuel tanks are deployed in the central reservoir side of the surface of the battery and back with aluminum (Al) alloy casing, the upper and lower exterior of the resin. “As one of the first volume of products, they attach great importance to the longevity and strength, a large number of metal parts used (PA3399U-1BRS battery industry Fuel). Power production unit is placed in the grid electricity type plate and stainless steel plate as a fuel tank between the resin. Stainless steel plate with the fuel is the result of rivets fixed so I can break no, you can not remove the plant. Lattice-shaped stainless steel plate next to an entry device for generating electricity, fuel supply side of the board set up power generation and supply Fuel control the fuel pump ground fuel valve. Control floor installed on the fuel pump and fuel control valves, and 8bit MCU and other IC.

 

Generating unit installed on pumps and fuel valves and other components with the corresponding control IC. Most IC is designed for the development of fuel batteries.

 

Generation unit is equipped with eye-catching is that the fuel valve and fuel pump (Figure 4). Since both mechanical drive, making it more energy efficient, ensuring sustainability issues. In addition, the portable fuel PA3399U-2BAS battery requirements for the smallest and thinnest high, so according to conventional wisdom, this part is the penalty “(personal fuel battery technology). Methanol from the fuel tank in plate fuel, the use of pumps to supply the entire MEA (a). The amount of methanol injection tank of fuel can be used to adjust the fuel valve (b). Vibrating piezoelectric element can change the pump pressure, injection / discharge of fuel (c).

  

Toshiba, the design of the fuel valve also takes great care. In comparison with other components, valve projecting fuel approximately 6mm. Compared to the fuel pump and control the installation of floor and other parts of the whole thin, it seems that only the fuel valve may not have time to develop products with low profile. Therefore, the position of the fuel distributor installation with the Center are also shifted by two power units contrast adjustment, while the reduced thickness of the battery. Power production unit consists of four devices into a single chip set consisting of the MEA. MEA area of approximately 40cm2. As there are two units of energy, so the output density is estimated at around 25mW/cm2.

 

In addition, the fuel pump using the PA3399U-2BRS products Murata Manufacturing. His use of a piezoelectric element, thin size to 24mm × 33mm × 1.325mm. Output rate 0.001mL / s, discharge pressure of 35kPa. To supply fuel for power generation and methanol through the fuel valve and the first supply of fuel entering the injection plate. Then, with the fuel pump to make two small holes in the center plate diffuses across the device.

 

The density of production of about 25mW/cm2

 

Power production unit from the outer dimension of 81mm × 52mm MEA (membrane electrode composite body) and body composition collector. MEA unit using four 81mm x 9mm. Think that the unity of the electromotive force of each piece is approximately 0.3 V, 1 Ge voltage generated by the power units to just over 1V. After generating unit control with step-up circuit on the raised floor to 5V or so. Pro forma density unit of output, only about 25mW/cm2. It was also suggested that “the problem may be heat-density limit output to such a degree “(a personal fuel battery technology). Regarding the solid polymer membrane, called” now under development are two types of fluorinated hydrocarbons and (Toshiba), this product is used which is unclear. But the majority opinion that “the possibility of greater use of fluoride” (a number of staff to fuel battery technology).

 

The direct use of experimental floor

 

Is located in the lower part of the power switch the PA3421U-1BRS battery terminals and input and output have been installed in the control on the floor. Dynario equipped with lithium-ion rechargeable battery. Its role is to control circuits for the units of electricity to power and the unit production of electricity from the start-up power smoothly before the burden of supplying electricity. Power switch part and the part of the control input and output separate floor. Backplane with two connectors connected. Power switch on the bottom to receive electric power generation interface unit (a). Backplane on the input terminals and output are connected lithium-ion rechargeable battery interface (b). Control of Lithium-ion rechargeable batteries and units of electricity seems to be controlling the power switch integrated flash on the floor 8bit MCU. The MCU can be rewritten, a large number of test pads on the chassis of speculation, including the control unit of power, including low, the product may be directly followed the experimental floor (fuel Staff batteryular technology).

 

In addition, the power switch on the bottom also installed 2 Mbit / s flash memory is considered to be used to save time loading and temperature changes. Lithium-ion rechargeable battery and control input connections and output terminals of motherboards for the bottom to provide a driver circuit units of electricity. As Dynario is the first volume of portable fuel batteries, Toshiba strongly under the law to ensure safety. As he had when the battery stop working automatically when the temperature rise function. For this purpose in entering the power generation unit is equipped with a temperature sensor to monitor the surface temperature, so it does not exceed a certain interval. Our tests confirm that when the surface temperature reaches about 45 ℃, the battery will automatically stop working.

 

In addition, the company said in response to temperatures above 100 ℃, the battery is also equipped with temperature starting capabilities and cons screen input terminals and output in the high current function.

 

Fuel Bottle also pays attention to safety

 

Dynario now need to use 50 ml vial filled with fuel for fuel. Fuel bottle with Toyo Seikan, develop, and the PA3534U-1BRS battery, as security have not been lax. Bottle with a double structure, in line with the IEC (International Electrotechnical Commission) safety standard (interim standard). “Even with 100 kg of withstanding the impact will not be damaged” (Toshiba). In addition, the company said, in exceptional form Pingzui and the role of internal agency, as long as the stack of fuel injection in the entrance channel which is not correct, the fuel does s’ sells it.

Thirdly, key initiatives aimed at solving environmental problems is the full implementation of the policy of recycling batteries

 

China is actively pursuing the circular economy, waste batteries can be recycled to 90%, but the industrial policy of China does not waste battery recycling a good development space, resulted in their becoming long-term problem bottleneck in the development of China Battery. China is not a lead-acid battery management of waste recycling, legal standards, the country was not prepared to conduct business waste professionals acid battery recycling, not a business or professional secondary battery recycling lead companies to establish a national network and a network of regional collection, recovery of all the work is the decentralized management state of unrest, the recovery rate of waste lead-acid batteries n ‘ is not high. Problems recovery of lead in non-standard commercial rehabilitation and strengthening of management is imperative, the state departments concerned should the policy as soon as possible, as the ban small coal mines, small smelt, as after a waste recycling lead small businesses. At the same time put in place policies to encourage and support large-scale manufacturers of Dell Inspiron 5150 battery recycling used batteries. Limiting the development of secondary industry to lead China are main factors: first, the cost burden of environmental protection equipment. Companies with advanced technology, the protection of the environment and well equipped to benefit the company not modify the technological backwardness of the serious pollution of the city “lead smelting small.” Second, surveillance is not enough. None business license is also under secondary lead production, correction palliative, were closed for “low melting lead, the wind is over, the resurgence. Thirdly, industrial policy is not conducive to business informal. Tax too heavy also undermined an advance regenerated large enterprises to increase the capacity of environmental governance. 

 

Fourth, the development trend of China’s lead-acid battery industry

 

Discharge is more than one hundred years old lead-acid batteries due to low cost materials, simple technology, the technology is mature, self is low, maintenance free characteristics of needs in the decades to come, still dominant in the market although the starter used, the power market space battery in May will be a turning point in the near future the development of domestic industry will remain dominant in the medium term will also be a place in the long term without is necessary to use high weight ratio of energy continue to exist. Currently, its major application areas of origin such as motorcycle motor, power supply parts, etc. in the substantial growth, but also in new application areas such as electric bicycles, buses can be used such as the development of valve-regulated development of hp Pavilion DV1000 battery technology to meet the high technology, such as UPS, power and communications equipment, food needs. As the lead acid battery technology continues to advance, making the electric bike industry, tremendous development, and to fuel cars and fuel to reduce pollution from motorcycles to make a contribution. Maintenance free technique, drawing technology in the grid net for the rapid development of the automotive industry. We can say in these applications in lead-acid battery technology advances to improve the competitiveness of the country has made real contributions.

 

Power tools, electric bicycles and other industries demand for small mobile battery industry has spurred the rapid growth momentum. Electric bicycle battery set most VRLA batteries after a performance improvement, energy and life cycle of a breakthrough, but so far remain in the high flow rate that energy is not quite high, deep-cycle life is not long enough gap largely affected the rapid growth of the electric bicycle industry.

 

Electric bicycle as a means of transport in less developed countries in recent years, rapid development, particularly in China. From 2000 to 290,000 in 2005 developing 12.09 million, the rate of average annual growth of 174%. It is expected that in the future for a long period of time, the batteries of electric bikes products will flourish. China’s Electric Power batteries bicycles used lead-acid batteries for more than 95%. 2006 Electric Bicycle sony VGP-BPS2 battery capacity of 40 to 50 billion by 2015, the output of electric vehicles in China will reach 1,000 billion yuan, including 16.0 billion supporting cells. The secondary market to replace the battery 480 billion, which is a huge market.

 

5, lead to China industrial battery acid, the direction of development envisaged

 

⑴ encourage bigger and stronger, improving the degree of industry concentration

 

To upgrade industry clustering effect, actively respond to various market risks, with equipment, manpower, technology, and effective integration, reduce waste, training of the optimization structural product additional columns for increased investment in efforts to protect the environment, an effective solution to pollution problems in the production process and further strengthen the leading companies in overall strength and realize the magnitude and Development group.

 

⑵ upward trend of lead acid batteries

 

To seize market to expand the size of the lead industry of toshiba PA3421U-1BRS battery acid, and strive for annual production of 2010 of approximately 131.75 million KVAh, sales income of 66 billion yuan.

 

⑶ be development-lead acid batteries

 

Although the lead acid battery technology continues, but the specific power, cycle life and other issues is always the emphasis on industry issues. Therefore, increased efforts in R & D efforts to improve the level of scientific research to enhance competitiveness are the only way for industrial development. Across the bridge and link between the role of the Association, and vigorously for businesses to create a platform for exchange and communication with the upper lead, partitions and other downstream industries, such as vehicles form an electrical and mechanical joint research and development, a group formed to unite foreign ALABC or a similar alliance to jointly research and development and strengthen R & D capability.

 

⑷ accelerate the adjustment of product structure, standardize the market recovery and regeneration

 

Increase the proportion of new products, develop sound and resource efficient products, focusing on the development of sealed maintenance-free lead-acid batteries, the phasing out of open-type batteries. Lead acid batteries to accelerate the technological transformation of enterprises, the use of process equipment for advanced and effective monitoring of the production process problems of environmental pollution, to achieve higher production clean. Encourage colloidal lead-acid batteries, winding type bipolar lead-acid batteries, and other new types of apple A1079 battery research and development, improve the use of more power and lead to regulate the market lead - Recovery of acid batteries and recycling, reducing waste lead-acid batteries of environmental pollution, noise oriented and resource management.

 

⑸ expand, standardize the export market to avoid trade frictions

 

A careful study of the international market demand, the range of export products appropriate adjustments to reduce the export price of competitive products, development of new applications and markets. Occupy the market share of low price, it exports the lead acid BATBL50L6 battery blow to China. At the same time, may be subject to foreign anti-dumping lawsuits, resulting in higher product has been imposed anti-dumping duties, loss of self-rising prices fair. Therefore, the Association should play in regulating the order of foreign trade and industrial development in the role of coordination to protect the legitimate rights and interests of enterprises, establish a standard order of competition to prevent abusive behavior cheap exports. Also studied the relevant policies of the country’s target market to consider establishing manufacturing bases abroad.
