new camera battery

In recent years the rapid development of wind farms,laptop battery  but because of its lack of reliability of power and unpredictable, therefore, to ensure stability of supply and profits have increased electricity suppliers race to develop a energy storage technology.

Hawaii officials hope that by 2030, 70% of energy needs to provide the origin, while the state faces the problem of wind power, mainly the energy sector is not measurement of wind generation in excess near the company can not enter the light wind power. If the local Maui (Maui), the total capacity of wind energy could reach the island, a quarter of the peak power, peak power and peak demand, but time is not the same, This brings to Hawaii to accomplish difficult goals.

“New York Times, said that the best option currently seems to use batteries. In New York and California, the energy sector is to develop technology for energy storage, even “wear” space, namely the use of these lower prices to buy the hours after midnight electricity sold at higher prices after a few hours. In the region of U. S. Midwest, another kind of one public service by showing the energy storage technology in a minute or even in a short time to load Fang Dian Ke repeated several times the conversion to help Dianwang cons Yangneng Tai, transmission failure Fengneng 以及 Bo Dong. In Texas, power companies placed at different locations through a transmission line connecting the battery to stabilize voltage.

Many companies believe that the wind energy industry, renewable energy targets can be obtained. Hawaiian Electric spokesman 彼得罗赛格 (Peter Rosegg) said that if the energy source is intermittent, “No battery will not achieve its objectives.” The company agreed to leave the island of Oahu (Oahu) north of the coast to buy a wind farm power. 30 MW installed capacity of power plants by the Xtreme Power Company to install a battery of 15 MW.

Saige said Luo, the plant is located in Hawaii, the best of a wind site, but its volatility diet, lack of stability. In addition, the electricity market is Honolulu on the island farthest from the location of the company’s distribution center, even from the company’s infrastructure of high voltage transmission.

Xtreme Power Kaluosike President (Carlos J. Coe) has said, the computer will try to keep the battery in the day mostly in the semi-billed. If the wind suddenly increased or decreased, the battery current will be stable, while the government seems to gradually increase or decrease.

Hawaii success lies in its production of wind energy, the adjustment function of frequency. air conditioning system to run 60 cycles per second, while the battery can be done in 60 seconds to discharge the tax or change in the opposite direction of frequency stability in order to maintain. battery system can be used for profit, the store’s low-cost electricity, while the liberalization of electricity prices. The battery can hold up to 10 MWh of electricity, equivalent to 30 megawatt power plant produces 20 minutes of delivery of power at full load, the incredible storage capacity.

First Wind Company and companies Xtreme Power battery has not revealed the cost of the system, but public figures, the cost of the wind farm is about 130 million dollars, the battery system, which costs U.S. $ 10 million The U.S. Department of Energy provided $ 117 million U.S. loan guarantees. ($ 1 6,78 yuan)

cost of storing power and value to consumers is difficult to predict. electricity during off-peak storage costs, and the highest cost of electricity is very expensive. “New York Times, said that while renewable energy sources to reduce dependence on coal and natural gas demand, which is an added advantage.

Kaluosike estimate the effectiveness of the battery system for more than 90%. If this figure is confirmed, the battery system is certainly a big step forward. Currently, the most efficient use of energy stored as pumped storage is that its efficiency of 70% to 85%.

Electricity is also used to store electricity and other strategies for the FM band. Beacon Power is building a library consisting of 200 flywheel energy storage system for electricity, and ensure that the AC system out in 60 cycles. The top of the wheel is interchangeable for use as generator or motor device can store or access to energy in the flywheel. U.S. Department of Energy cost of $ 69 million for this project has provided 43 million U.S. loan guarantees.

U. S. Department of Energy that use of the proposed storage of compressed air energy to provide support. The excess electricity to pump air into underground caverns, where you need electricity, vacuum in the gas turbine generators.

VRLA battery charge sony VGP-BPS21A batterybalance principle of VRLA batteries (hereinafter referred to as valve-regulated batteries), with savings in investment, easy installation, safe, reliable, easy to use and other characteristics of the actual valve regulated lead acid batteries (hereinafter referred to as valve-cell), with savings in investment, easy installation, safe, reliable, easy to use and other characteristics, in practical applications has been widely used. However, a lack of understanding of their application requirements, and follows the old balance charging system, battery causing great harm.

1. Reason cancel the equalizing charge

(1) What is a balanced charge

The so-called balanced charge, cell characteristics, the balancing charge, is the use of the process of the battery, because the battery’s individual differences, temperature differences have caused the battery terminal voltage Buping Heng, To avoid this imbalance Qushi deterioration Xu Yao improve battery group charge voltage, activation of the battery charge.

(2) no reason for equalizing charge

First, the concept of the concept of a balanced charge in the old-fashioned lead-acid batteries made using the most current major valve-regulated batteries are clearly stated, “Voltage balance, into thoroughly.” And “do not form within the battery acid level, without the need for balance charging.” For single battery charge voltage of 2.4V is defined as accelerated charge, that “FASTCHARGE”, not “EQUATION”.

Secondly, the balanced valve-regulated battery charging will cause damage. Equalization charge voltage for the majority of batteries are higher float voltage. At this point, most normal cells are in the overcharge state. Gas in the battery can not be combined within a certain pressure, the pressure above the threshold valve, the valve opens, exhaust gas from the control valve.

In the previous battery maintenance, along with a balanced battery charging process is carried out to adjust the proportion, that approach by adding distilled water to add water to keep the battery in the balance. However, maintenance-free batteries, the maintenance of the existing system is without water, this way, water loss will inevitably result in the battery, the battery dry.

2. After the cancellation of a balanced charge, how to ensure the consistency of the battery terminal voltage

(1) battery terminal voltage of the decisive factors

Firstly, it is dependent on the concentration of electrolyte and electrode materials. Cell dehydration, electrolyte concentration must increase to increase the battery voltage. Secondly, open the safety valve. Such as the low pressure safety valve, will inevitably lead to premature water loss battery terminal voltage rise. In addition, the series connection between the battery state is different, and float, the charge will appear inadequate. When the battery is experiencing deep discharge recovery of further charge, it is difficult to restore, which will cause the battery terminal voltage is low.

(2) means the battery terminal voltage to ensure

Since the battery voltage will exist inconsistencies did not allow the battery to balance charge, then how to ensure the consistency of the battery terminal voltage? First of all, the battery should be the raw materials, production processes to ensure the consistency of the battery voltage. Choice of materials such as batteries, especially electrolyte, plate, pressure control valves and other key materials selection. Second, we must ensure that the quality of the battery installation, battery installation status to ensure consistency. For example, the battery connection method, torque balance and so on. Furthermore, we need to be concerned about the maintenance. For some behind the battery charge to be restorative, but also appropriate adjustments battery electrolyte; should regularly check the pressure valve in the working state.

2the of this month Provincial Science and Technology, laptop battery  CAS Shanghai Institute of Microsystems and Information Technology, Beijing University of Technology, China University of Mining, Harbin Engineering of the University and other institutions in experts and researchers in universities, Professor of Harbin Institute of Technology research team completed Kening “intermediate cell temperature solid oxide fuel R & D integrated,” outcomes evaluation project. This project developed independently casting “sintering technology” to reach the country in solid oxide fuel cell fuel cell large surface of the substrate prepared basic technological breakthroughs, the single battery and the power density and thus reached the international advanced level.

Known fuel cell fourth generation, fuel cells Solid Oxide “, in relation to the three previous generations of fuel cells, fuel adaptability, all semi-conductors, modular assembly, preservation of the energy, zero pollution, etc., can be directly used carbon monoxide to hydrogen, natural gas, LPG, gas and biomass gas and other hydrocarbons. Concentration of power in large, medium and small cogeneration and electrical sub- other civilian areas have potential applications, and can serve as a force for submarines, power shipboard service and auxiliary power units and other troops in armored military has also wide range of applications potential.

Ocean University of Tokyo and Tokyo currently ship motors, Fuji Heavy Industries, Yokogawa Electric laptop battery , Yamaha engine, Tokyo Electric Power and other companies formed five common cause of body plans start battery-powered fishing boats. The plan to lithium as kinetic energy, with the rapid charging system for the world to build and transport aircraft of the first battery-powered fishing boats, to achieve a low carbon society and the effective prevention of noise is expected to be able to change laptop battery the way the marine low environmental transmission.

Total project executor of the head of the University of Marine Science and Technology, Professor Takamasa said: “Do not worry about the ship exhaust gas emissions will pollute the water, noise and vibration are also reduced. In the future would also like to engage in fishing development.” Positive Test match at the same time through the study and vigorously promote the development of its utility.

It is reported that the rapid charger set designed and built by the University is responsible for, participating companies will invest in technology and sponsorship funding.

First study found that compared to traditional battery-powered ship diesel engine ships, 100 decibels of noise can be reduced to 60 decibels, low-noise technology, but also within 30 minutes, 80% of the charge, and the traditional need to spend 10 hours to charge compared to lead batteries, there is an epoch-making to enhance usability.

Ship, by the spreadsheet for the conventional diesel engine boat 1.3 times to 1.5 times the cost of fuel (electricity) can be Ya Jian to the conventional diesel half (for the sixth night) level.

Professor Takamasa Note: “Low noise, ground vibration, not emit gas emissions. For future low-carbon society, I think this is a must ship drive change,” discuss how to best of their power and public sex technology, development of an empirical test, is expected late in 2010 to the practical.

Toshiro Takeuchi, Vice President, said: “Our school of ‘environment’, ‘resources’, ‘energy’ as the three pillars of research. Reveal the battery propelled Ship Research and Development, also hope to advance environmental protection and efficient use of resources such as” show a positive attitude.

The school is also to help spread EV (electric vehicle) with a charger cause, last March, the school for the first time in the campus setting EV to use the rapid charger. Electric vehicles using lithium batteries in the islands by the Vietnamese and Shinagawa Research Laboratory within the campus.

Advance the construction of the battery now ship, on July 19 the day of open sea. Then, the more the university campus in Shinagawa Inter-Island and sailing, the actual navigation of the data accumulated for future improvements.

Evatran announced recently laptop battery  developed a magnetic sensor technology, hands-free electric car charging stations Plugless Power, he did not need your hands to your son can be the vehicle battery friendly environment is fully loaded.

This form is like a recharging station pedal, as long as the bus came near him, you can start buying electricity costs to compensate for energy losses during transmission, which increases the power station charging, charging the program slightly, while the cost of other power, but it can be saved in labor costs and operating expenses to cover Evatran plans to begin production in early 2011 Plugless.

Electric vehicle (EV) with a lithium-ion rechargeable laptop battery again for the storage of electricity provided by solar cells, as well as industrial equipment, power supply and other uses would become increasingly active in a wide range. Although the car battery used in EV 5 to 10 years, the battery capacity will be reduced, but the “rest of the initial capacity can reach 70 ~ 80%” (Nissan). Although more difficult again for automotive use, but this capacity will fully meet the needs of home-style power-storage applications, due to extended battery life, it also helps to reduce costs.

Scheduled in December 2010 listing of EV “green leaves” and Nissan Motor expects 2020 battery demand in Japan will reach the equivalent of 50 000 EV usage. The company has begun to explore with Sumitomo car battery recycling issues.

The same with the Nissan, GS Yuasa, Mitsubishi Corporation, Mitsubishi Motors and Lithium Energy Japan (LEJ) four companies, in order to recycle Mitsubishi EV “i-MiEV” is equipped with lithium-ion rechargeable battery, Fall 2010 Positive test starts in Kyoto city. In practice, development and solar cells, lithium-ion rechargeable battery and quick charger, rapid charging system, the combination of “PV-EV system” for recovery using i-MiEV is equipped with lithium-ion rechargeable battery “LEV50″ (LEJ Manufacturing ). The company plans to Kyoto city lots, as ordinary users can use set the PV-EV system to accumulate empirical data.

PV-EV systems usually use solar cells to provide power for the battery charge when the battery’s remaining capacity reduction, you can also use the system power. Also available when the battery is fully charged, so that the remaining solar power upstream to the system power functions.

In addition, Itochu has also started to recycle the United States car EnerDel battery of empirical tests.
