German solar company solar panels on Chinese anti-dumping investigations
According to the German “Handelsblatt” 21 days, German solar manufacturer Conergy Company wishes to join forces with other colleagues to the German government and the European Commission to apply to the solar panels made in China, an anti-dumping investigation. Conergy’s CEO Ammer (Dieter Ammer) said: “The prices are dumping marginal”, Inspiron 700m battery according to the current price level, Chinese manufacturer has no support from the state can not be profitable. Since the silicon solar panels the prices of raw materials is open, the Chinese manufacturer has only low-cost labor and energy advantages. The proposal in the German solar energy industry, enjoy wide support, and other producers also believe that the competition with their Chinese counterparts at a disadvantage. German solar giant Sorlarworld Asbeck, chairman of the “Daily” said: “China is clearly in the price-dumping.” German Solar Energy Economic Association, laptop battery said the Association is currently collecting information from the decision too early. Reported that since last fall, solar panel prices have dropped by 30 percent, because banks and credit institutions to tighten credit for solar projects, WestLB and Royal Bank of Scotland have all been stopped financing for solar projects, thus decline in demand caused by increase in business inventories, companies have to price changes.

Trade-in electric car batteries will no longer pollute the environment

September 28th, 2009 admin No comments
Light non-emission electric vehicles to facilitate by the public. Yesterday (24) days, a reporter from Shunqing district traffic police brigade was informed that only the main city Shunqing registration license plate of the electric car will have more than 9000 vehicles, coupled with excessive can not go to a total of 15,000 vehicles licensed. Such a large electric vehicle team, and its battery, if not handled properly it will cause great pollution to the environment. Then the electric car battery Nanchong is how to recover it? Reporter from the municipal environmental protection bureau was informed that the city’s electric car batteries generally by selling commercial “trade-in” and other forms of updating or recycling, the basic no pollution to the environment.
In order to recover the main dealer
It is understood that under the used batteries belong to the state hazardous waste management areas. From an environmental point of view, lead-acid batteries to the environment, human health, the most damaging of a battery, if not take a more comprehensive system of recovery of waste lead-acid batteries  PCGA-BP71 battery , PCGA-BP71A battery to discard break out of the ecological balance of heavy metals and toxic waste would be and poses a serious threat to human health. Human intake of lead can cause neurological metabolic, reproductive and mental aspects of the disease can be fatal in severe cases.
Nanchong City Environmental Protection relevant person in charge told reporters that the lead-acid battery electric bicycle is a consumable, brand battery for 1 to 2 years to be replaced, brand-name battery for half a year to be replaced. A large number of provinces, municipalities and clear that the market for electric bicycles, where the use of lead-acid maintenance-free batteries, all from the manufacturer through the distribution unit of recovery, a unified cross-manufacturing enterprises processing; where to buy a new battery must return the used batteries but not otherwise buy a new battery. Electric vehicle battery recycling is currently Nanchong basic to such a mechanism-based, and environmental protection departments to oversee vendors effective recycling of waste batteries.
In addition to recycling dealers outside, and some businesses are also recycling of used batteries PA3331U-1BRS battery , PA3331U-1BAS battery processed, and then sold to consumers at low prices. It is understood that, in order to reduce costs, some businesses will batteries apart, and then put inside the waste acid drained. Municipal Environmental Protection Bureau relevant person in charge pointed out that such behavior is illegal, along with environmental protection department will be investigated and dealt with discovery.
Recycling profitable and will not litter
In addition to mechanisms for protection of battery recycling, the more important are the interests of drive tube could be sold to consumers money, or trade-in, it will not litter.
City People’s Road an electric car sales company manager, told reporters scrapped lead-acid batteries can be repaired, restored the effectiveness of up to 80% of new battery for more than the 2nd repair more than 50% after three times until there is no fix to repair. Company’s sales of the electric car battery implementation of “trade-in.” Customers to take waste batteries, and then pay the 350 yuan of money, you can get the value of 500 yuan a new PA3384U-1BRS battery . Recycling of scrap batteries returned to manufacturers unity, manufacturers can still be restored to the battery through a dedicated technology, repair, re-put into use; to the total damage to the lead-acid batteries can not be repaired, recovered by a qualified lead and zinc processing enterprises, refining Secondary Lead . Since the current higher prices of lead, recycling prices mostly in the tens of dollars to several hundred per hour, so consumers will not be lightly discarded.

Main performance parameters of the battery

September 28th, 2009 admin No comments

 The main features include battery electromotive force, rated capacity, rated voltage, open circuit voltage, internal resistance, charge-discharge rate, resistance, longevity and self-discharge rate.
Emf
Electromotive force balance between the two electrodes of the electrode potential difference, to lead-acid batteries, for example, E = Ф +0- Ф-0 + RT / F * In (αH2SO4/αH2O).
Where: E-emf
Ф +0- positive standard electrode potential, its value is 1.690
Ф-0-negative standard electrode potential, its value is -0.356
R-universal gas constant, its value is 8.314
T-temperature, and PA3191U-1BRS battery in which the temperature on
F-Faraday constant, its value is 96500
αH2SO4-activity of sulfuric acid, and sulfuric acid concentration of
αH2O-water activity, and the concentration of sulfuric acid
As can be seen from the previous style, the standard lead-acid battery electromotive force for the 1.690-(-0.0.356) = 2.046V, so the battery nominal voltage of 2V. Lead-acid battery electromotive force and temperature and sulfuric acid concentration.
Rated Capacity
In the design requirements of the conditions (such as temperature, discharge rate, termination voltage, etc.), the PA3356U-1BRS battery should be able to release the minimum capacity, in ampere-hours in order to sign C said. Capacity greatly influenced by the discharge rate, so often in the lower right corner of the letter C with Arabic numerals indicate discharge rate, such as the C20 = 50, shows that the capacity under the 20:00 ratio of 50-an-hour. The theoretical capacity of the battery cell reaction according to type of electrode active material usage and calculated according to Faraday’s law of electrochemical active substances derived equivalent accuracy. Since the battery in the side effects that may occur as well as the design of the special needs of the battery’s actual capacity is often less than the theoretical capacity.
Voltage
The battery at room temperature, a typical operating voltage, also known as the nominal voltage. It is the choice of different types of batteries for reference. The actual battery voltage with the different conditions of use vary. The ThinkPad T42 Series battery open circuit voltage is equal to the positive and negative electrodes of the balance of the difference between the electrode potential. Only with the type of electrode active material, but not with the number of active substances has nothing to do. The battery voltage is essentially a DC voltage, but in some special conditions, the electrode reaction caused by the metal crystals, or some of the phase transition into a phase membrane will cause a slight voltage fluctuation, a phenomenon known as noise. Volatility small but very wide frequency range, so the circuit can be distinguished from self-excited noise.
Open-circuit voltage
Battery terminal voltage under open-circuit condition is called open-circuit voltage. Open circuit voltage is equal to the battery when the battery in the circuit (ie there is no current through the bipolar pm) battery positive electrode potential and the anode electrode potential difference. The ThinkPad X60 battery open circuit voltage with V opening, said that the V open = Ф +-Ф-, which Ф +, Ф-positive cells were negative electrode potential. The battery open circuit voltage, generally less than its emf. This is because the two poles of the battery electrolyte solution in the electrode potential established is usually not a balance of electrode potential, but the stability of electrode potentials. Generally similar to that of the open circuit voltage of the battery is the battery EMF.
Resistance
The battery internal resistance is the current through the battery is subject to the internal resistance. It includes the ohmic resistance and polarization resistance, polarization resistance, but also the electrochemical polarization resistance and concentration polarization resistance. Due to the presence of resistance, the battery voltage is always less than the battery emf <IMG src=”http://t12.baidu.com/it/u=2325898283,3451946212&fm=0&gp=10.jpg” name=pn19> or open-circuit voltage. The battery internal resistance is not constant, in the charging and discharging process of change over time (progressively larger), this is because the active substance the composition of the electrolyte concentration and temperature are constantly changing. Ohm’s law Ohm’s resistance to comply with the polarization resistance increases with the current density increased, but not a linear relationship. Often with the current density increased.
Resistance is to decide an important indicator of  ThinkPad T61 battery performance, it directly affects the battery voltage, operating current, the output energy and power, for the battery, its internal resistance as small as possible.
Charge-discharge rate
Sometimes rate and magnification two kinds of representation. Charge and discharge time when the rate is expressed by the charge and discharge rate, numerically equal to the rated battery capacity (ampere-hour) divided by the provisions of the charge and discharge current (An) obtained the number of hours. Magnification is the charge and discharge rate of another representation, the reciprocal of the rate of its value too. The battery discharge rate is based on the original by a fixed resistor to the termination voltage discharge time to that. Discharge rate greater impact on battery performance.
Impedance
Electrodes inside the battery has great – electrolyte interface area, it could be the battery is equivalent to a large capacitance and small resistance, inductance in series circuit. However, the reality is much more complex, in particular, the impedance of the battery and the DC level over time change, the measured impedance is only valid for specific measurement of the state.
Life
Storage life refers to the beginning of the use of the battery is made between the maximum time allowed to store to-year unit. Including the storage period and the use of total duration of that period, including the validity of the battery. Save battery life there is dry storage and wet storage life of life points. Is the  FRU 42T4511 battery cycle life under the specified conditions are met can achieve the maximum charge and discharge cycles. The specified cycle life must also provides charge-discharge cycle test systems, including the charge and discharge rate, discharge depth, and ambient temperature range.
Self-discharge rate
Storage batteries in the process of self-capacitance rate of loss. Save time with the unit of self-discharge accounts for the loss of storage capacity before the capacity expressed as a percentage.
The calculation of the FRU 92P1137 battery
Where E is emf, r for the power supply resistance, internal voltage U in = Ir, E = U, within + U external
Scope: pure resistance circuit
Closed circuit in the energy transformation:
E = U + Ir
EI = UI + I ^ 2R
P release = EI
P output = UI
Pure resistance circuit
P out = I ^ 2R
= E ^ 2R / (R + r) ^ 2
= E ^ 2 / (R ^ 2 +2 r + r ^ 2 / R)
When r = R when the P output maximum, P out = E ^ 2/4r (mean inequality

2009 global solar cell production growth will be less than 30%

September 25th, 2009 admin No comments
Japan Yano Economic Research Institute latest report shows that due to Spain’s restrictions on FIT (Feed-in Tariffs; the power companies to buy back solar power and other new high-energy power generation electricity) policy scale, combined with the U.S. financial crisis triggered by the aftermath of the global economic downturn is now spreading across to the solar cell market, it estimates the 2009 global solar cell production will be 8.295GW, annual growth rate of only 27.5%, far less in 2008 to nearly 70% growth rate.
Investment Advisor in the new chief researcher Jiang Qian pointed out that the energy industry, integrated in the first half and three-quarter view of the circumstances first two months of 2009, annual global production  Inspiron E1505 battery , C1295 , D5318 of solar cells less than 30 percent growth rate is also reasonable. First, the financial crisis on the impact of PV industry in first half of 2009 has been most evident, a substantial loss making enterprises have laid off a lot of cutting down oil production, which in particular in the most prominent German companies.
With three quarters of global economic recovery since the signs of obvious gradually out of the photovoltaic industry is in a downturn period, an increase in orders has prompted companies have been “recruiting” is one of China’s PV manufacturers representatives.
In addition, Inspiron 6400 battery with the slowdown in production of solar cells that corresponds to that in 2009 a new global scale installation of photovoltaic power generation system will also be likely to drop sharply. Market research firm iSuppli latest data show that in 2009 the world’s newly installed photovoltaic power generation system will reach 4 gigawatt (GW) or so, most of them in Germany. Germany will be installed 1.5GW, Italy 580MW, there is 300MW to 400MW will come from Spain, California and Japan.
Jiang Qian believed that the decline in newly installed capacity is mainly reflected a substantial decline in the Spanish market, this has proved once again that the solar PV industry at the present stage of the “policy market” characteristics.

Yano also said that although the follow-up solar cell market is expected to continue to expand, but to enter the solar cell market as vendors continue to increase, in the past continue to successfully expand the market share of large companies will also be into a bitter struggle, in the future solar market from the old ” made out of respect as the hybrid (HV),laptop battery  as well as the best-selling electric vehicle (EV) the introduction of lithium-ion rechargeable batteries, more and more attention. expand the use of lithium-ion rechargeable batteries, the pace is accelerating, Executive Chairman of Hitachi, Ltd. Takashi Kawamura president and chief executive, said: “will be for the use of social infrastructure and industrial development of large lithium-ion rechargeable battery.” symbolic significance of which is that Hitachi will be within the year 2009 as a wholly-owned subsidiary of Hitachi mack.Saerna  . Hitachi, Ltd. in the future not only for consumer products and electric vehicles, will be facing the electric power storage and industrial equipment to carry out lithium-ion rechargeable battery business.
Lithium-ion rechargeable battery, as the potential uses, the industry is hybrid and electric vehicles such as electric vehicles, high hopes. But at the moment the automotive industry for reliability and durability concerns, on the use of lithium-ion rechargeable batteries, be cautious, the market takes time to expand.
Under such circumstances, there has been prepared without first for the automotive and the first power-storage market for set-based lithium-ion rechargeable battery production enterprises. This is the ELIIYPower. As Japan’s Keio University, created the risk of the company, the company plans within the year 2009, Kawasaki City, Kanagawa Prefecture set up factories planned in 2010 with an annual output of 200,000 of the scale of production NF343 , PC764 , TD347. Will strive to reach an annual output of 1.2 million. Units used cathode material for safety and durability are excellent lithium iron phosphate.
Despite Japan’s economic slump was still in the situation, but for the establishment of production bases and to strengthen the financing of research and development progress very smoothly. Its inception in 2006, only the large and Housing Group, Dai Nippon Printing, and Sharp, and other enterprises funded, but by the end of May 2009 and before that received 7.5 billion yen of new funds for the production bases. Among them, the international oil development Emperor Shi, Mitsuuroko, Yaskawa Electric, Hing Bank Leasing, JAFCO (JAFCO), YokohamaCapital have been funded for its.

Hydrogen fuel cell technology in China’s booming

September 23rd, 2009 admin No comments
Recently, an upstart company by the British Riversimple manufacturing zero-emission hydrogen-powered vehicles available in London, the car can take two people, maximum payload of 350 kg, a maximum speed of 50 miles / hour per gallon of fuel to travel 350 miles. The car as a city car to carry out promotion. The use of hydrogen fuel cell car from Shanghai Fuel Cell Technology Co., Ltd. Qing able to produce.
As the global development of clean alternative fuel vehicles have soared, driven by hydrogen fuel cells the number of vehicles is also growing rapidly. Shanghai Qing energy fuel cell technology Co., Ltd. Chief Executive Officer George Gu said that the use of hydrogen fuel cells and hybrid electric vehicle battery portfolio will be the development of a new direction.
George Gu believes that the weight of batteries due to their own problems with many restrictions. Use the weight of large vehicles need more battery power to drive itself. However, by hydrogen fuel cells and dell Inspiron 1520 battery requirements for motor vehicles was divided between cruising and accelerating momentum, then the hybrid vehicle can be like a normal car-driving, he added.
George Gu said, “Fuel cells could be used to provide car cruise power capacitors, while the  Latitude C500 battery can provide peak power to accelerate.” “While the capacitor cell can also be achieved under braking to recharge the battery.”
However, a senior industry analyst at Global Insight Duan Wu expressed doubts about “taking into account all aspects of the obstacles, I believe that such vehicles will only be suitable for display purposes, also suitable for use up to a very limited uses, such as Expo or university campus. ”
Headquartered in Singapore, Horizon’s fuel cells produce almost 100,000, and a number of fuel cell vehicles to the developer supply, including fuel cell vehicles are engaged in research of Chinese universities. The company has 120 employees in Shanghai, with production and R & D base.
The Chinese government is promoting the development of hydrogen fuel cell vehicles. Shanghai Shenli Technology Co., Ltd. is also a developer of fuel cell technology, the company spokesman Sunny Sun, said the company is on the normal size passenger car’s fuel cell vehicle project in cooperation with the Government.
Sun said that the divine power the company’s hydrogen fuel cell power system can produce electricity to drive passenger car engines. Used to re-charge time is normally 10 minutes.
To re-charge time is installed in passenger cars on the hydrogen storage tank pressure and the size determined, Sun has said. If the pressure is high, re-charge time will be longer, or if large size, the time will be longer, but usually is 5 to 10 minutes of time.
Sun says that from the divine power company’s fuel cell-powered passenger cars will be in next year’s debut at the Shanghai World Expo.
At present, there are two hydrogen refueling station in Beijing, in Shanghai, GD761 battery is the only one. However, Shanghai will also build four hydrogen refueling station. She said, “By 2010, Shanghai will have five hydrogen refueling station available for 2010 Shanghai World Expo show at the fuel cell vehicle use.
