Recently, by the Zhejiang Provincial Science and Technology Department, Commission by letter, Zhejiang University, Tianjin eighteen other units of the appraisal committee of experts, the power of AMD’s “multi-stage lead-acid batteries free of cadmium within the formation process” to identify scientific and technological achievements. Identification of the Committee that the process in line with the national cleaner production, environmental protection development requirements, and concluded that the new energy battery technology in the domestic leading level.

According to reports, AMD “cadmium-free lead-acid battery formation process within the multi-stage” consists of two parts: first, charging into the traditional craft to the outside into charging process, will be cut after curing of the plate directly into the battery box, cancel the original into the outer tank, water washing, drying equipment, saving the labor and employment, electricity and water consumption, and to achieve zero discharge of wastewater; Second, the original battery cabinet with a large shunt current charger to the computer Intelligent control of the charge and discharge power recyclable energy, so that the original 95% of the discharge power is recycled. This transformation, the annual saving 2,230,000 kwh. The scientific computing, with AMD, “cadmium-free lead-acid battery formation process within the multi-stage” production of lead batteries, not only can save 28% or more, saving more than 90%, even more important is to solve a large number of lead-cadmium battery pollution emissions issues for lead-acid battery industry in China has long been troubled by water consumption and heavy metals lead and cadmium pollution problem provides an effective solution.

In recent years, with the automotive, telecommunications, electric cars (especially electric bicycles) and renewable energy storage needs of rapid growth, lead-acid batteries in China entered a period of rapid growth. It is understood that the present lead-acid batteries are widely used in cars, trains, tractors, motorcycles, electric vehicles and communications, power plants, power transmission, instrumentation, UPS power supplies and aircraft, tanks, ships, radar systems. With the world energy economy and increasing living standards, the use of the secondary power supply, lead-acid batteries has occupied more than 85% market share.

However, as China’s battery products, especially power-type battery commonly used products, formulation and application of traditional external cadmium technology into production, resulting in excessive levels of cadmium and lead and other pollutants generated and energy, wasted water, lead contamination problem has been seen not only criticized, but also become a bottleneck restricting the sound development of the industry.

In this context, AMD “without cadmium within the multi-stage lead-acid battery formation process” R & D success, the importance of industry self-evident. China Electrical Equipment Industrial Association, the Ministry of Industry Development and Consulting Master Ren Wangkun that AMD in the absence of cadmium battery, the chemical process control and effluent zero discharge of heavy metals and other technical achievements made for the industry to clean production played a good role model. AMD Technical Advisor, Department of Chemistry, Xiamen University, Professor Chen said the body of the title, AMD “without cadmium within the multi-stage lead-acid battery formation process,” the adoption of new materials, new structures, new processes, new technologies solve the traditional process a large amount of lead, discharge of heavy metals cadmium industry technical problems, laid the foundation for the energy saving.

According to reports, AMD began to get involved from 2002 to the development of new energy products, through continuous technological innovation and process improvement, now has a mature manufacturing technology and industry conditions, especially in the electric vehicle batteries, solar and wind energy terms of energy storage battery technology has been leading the industry. The new energy products have been widely used in electric vehicles, wind power and photovoltaic lighting, and other supporting programs and projects, not only the outstanding performance and some indicators even more than similar foreign products, at the international advanced level.

AMD the leaders stressed that in the course of lead-acid batteries, and no pollution, and pollution generated in the production process, as long as the technology is in place and management are effective, can achieve effective control.

It is based on the development of philosophy, and with constant innovation, AMD is located in Jiangsu Province, the new production base of branches and the ground is not only clean, cleaning, sewage treatment and recovery in the pool stocked with fish swimming, and the air is also do not see any floating dust and dust, leaving only the faint hint of acidity. This wire sour, the company has plans to install similar range hood like acid gas absorption device, and strive to eliminate the source of the acid gas produced, but also plant a clean dust-free clean environment, but also a fresh air staff, which realize clean production.

AMD side said that at present, cadmium-free within the AMD technology into the production base has accounted for 40%, 80% in 2011, and eventually the whole formation process of cadmium-free production, green manufacturing for the industry to make due contribution.

Battery energy systems are the heart of new energy vehicles, some experts said recently that China’s new energy vehicles in future financial subsidies should be gradually master the core technology of battery energy systems business tilt.

Core technology is considered to be fundamental automotive industry, and the development of new energy vehicles in China auto industry is considered a rare “turn overtaking” opportunities. Since 2008, driven by the country under the relevant policy, the domestic auto industry launched a new energy development boom.

And industry experts said the new energy vehicles is that the new power system - the core of traditional automotive products, engine parts were replaced by battery energy system. Battery energy system is not only the core of new energy vehicles, but account for 40% of vehicle cost to 50%.

According to the analysis, the battery energy system consists of a composition of one of the single cells, single cell is the cell energy systems constitute the basic units. Therefore, the single battery technology is the core technology of new energy vehicles. Industry experts said that to master the core technology is the single cells of new energy automotive industry key to development.

Industry experts suggested that in the new energy automotive industry to upgrade the critical moment, the Government should be given in the policy and financial support of domestic brands, and target subsidies to rigorous review checks to prevent some domestic enterprises from foreign imports into the battery assembly of single cells group, and then sold to car makers and access to financial subsidies.

It is understood that China has emerged a number of core technology with single cell companies, including BYD, universal, MGL, the power of God, BAK and so on. BYD independent research and production of ET-POWER lithium iron phosphate batteries, has been used in BYD e6 business models. In the 2008 Beijing Olympic Games and 2010 Shanghai World Expo and Guangzhou Asian Games and other major international event, the same lack universal, MGL and other brands on the scene.

Data also shows that domestic brands of battery companies in human resources, capital, technology, and very weak, many of the core technology patents still rests in the hands of Western and Japanese and other enterprises.

Thus experts suggested that battery as the heart of new energy vehicles, must be the focus of enjoying government subsidies to ensure greater R & D capability and motivation.

With the fourth bus slowly left the bus company is located in Huzhou City, South Gate of the charging stations in the future people will be able to sit in Huzhou, Zhejiang Province smooth ride, lower energy consumption of electric buses, which also marks one of the first pure electric vehicle fast charge put into trial operation. Zheliang by the micro-macro dynamic Hengtong bus companies and the rapid production of rechargeable electric bus, 10 minutes to complete the charging process, a charge driving range to 30 to 50 km, and the traditional electric vehicle charging you will need 4 to 6 hours.
“The battery is currently restricting the development of the fundamental factors of electric buses.” Executive director Tang Heng Tong Ping Bus Company told reporters that the current market, they use a pure electric vehicle battery lithium iron phosphate batteries, the technology is relatively immature. According to estimates, the use of lithium iron phosphate batteries to carry 200-350kWh energy calculation, the battery weighs about 3 tons, the night charge to be 4 to 6 hours, a single life in the 150-250 km distance, only the basic operation to meet the bus lines, After a 1000 battery charge and discharge cycles, the capacity decay to 80% less mileage fall, the actual battery life of only 2 to 3 years. Not only difficult to meet the needs of urban public transport is running, can not achieve large-scale commercial operation. At the same time, is not conducive to charging network infrastructure and layout, but not conducive to public transportation network drive private cars charging energy supply network in the long term layout and construction.

“The use of a new fast-charge lithium battery Hengtong electric passenger cars, 2,000 times in the charge and discharge cycles, the capacity fading can still be maintained at about 98% charge and discharge cycles 20,000 times, to 80% capacity fading, the actual life of up to 6 to 8 years. “Micro-Macro Dynamics chairman Wu Yang said.

According to Deng Ping, Hengtong pure electric passenger car fast with a new long-life rechargeable lithium battery, car battery electric passenger volume than the traditional less than half the battery weight, so that vehicles over 1.5 tons of weight, improved capacity and power, reducing the purchase price. Meanwhile, the Hengtong pure electric vehicle fast charging during braking, the motor generator can be automatically translated into the work of the state, to achieve recovery of braking energy during deceleration, have a good retarding effect, but also to the life of brake system has been significantly improved. “In the future, simply run the bus company starting point, the terminal set fast charging pile, or each time to the starting point, the terminal just as fuel to meet the bus one-way or round trip alignment of power trip travel needs.” Deng Ping said, equipped with a fast charge battery electric buses this year will be in Chongqing, Guangzhou into demonstration runs.

According to world authority Firstre-search the data show that in 2010, Crystal Dragon Companies Group, JA Solar over the United States become the world’s first solar cell production capacity and sales of the largest solar cell manufacturer. In 2010, production capacity of crystalline solar cell Long has exceeded 2 GW (2000 MW), sold more than 1,400 megawatts.
Crystal dragon acutely aware of the technological innovation is an inexhaustible motive force for enterprise development. Over the years, groups use the crystal dragon’s technology center, Silicon Materials Research Center, solar cell R & D centers, four major solar energy research and development center component R & D center, and constantly research the world of technical problems, efforts to create world-class products. Through technological innovation, crystal dragon quartz crucible coating process so that pulling the core yield increased by 10 percent, favored, exported to the Korean market. 2010, Jing Jing Long’s Australian company developed a “game show” super-efficient solar cell technology by Fraunhofer world authority on laboratory accreditation, photoelectric conversion efficiency of 18.7%, higher than the international industry 1 percent. End of the year, the technology of photovoltaic conversion efficiency has increased to 18.9%, and has achieved mass production, are sold in Minnesota.
In business management, information capture market attention crystal dragon, which in time in the competition to seize market opportunities. In early 2010, from the financial crisis to get out of the shadow of the PV industry has just improved, crystal dragon has been the first project of the enterprise issued a mobilization order: seize the opportunity to full capacity, improve production, continue to enhance the pace of key projects and enhance their development potential. As a result, crystal dragon silicon, monocrystalline silicon, solar cells are all at full capacity throughout the industry chain operation, pulled off a PV market competition. The end of 2010, grain yield breakthroughs on the dragon pulling 1.2 tons, can produce single lines cut by the beginning of the year 110,000 to 22 million, solar cells increased from the beginning to the present 800 MW more than 2 GW. Products are sold to Germany, the United States and other countries and regions.
Currently, the Crystal Dragon 1.2 billion investment in solar cells started 20 production line is under construction, is expected to be put into operation in April. Put into operation, will bring the annual sales income of 4.6 billion yuan, profits of 10 billion huge economic benefits.

Development of electric vehicle charging facilities are the State Grid Company “second five” important strategies. Liu Zhenya, general manager of the national grid has said that after more than a year, the State Grid Corporation of charging for electric vehicles, power plants will be the basic business model as follows: the for-power-based, plug-in, giving the concentration of charge, uniform distribution. State Grid Corporation in 2011, Beijing, Hangzhou, Tianjin, Hefei, Nanchang city building electric car charging network for electric service. Meanwhile, LIU Zhen-ya also said, “will strive for electric vehicle charging station project pricing policy and taxation policy.”

This kind of “change battery” as the main mode of development strategy is the real part of the market power battery operation, the State Grid Corporation of equivalent “battery carrier” role, is also the largest battery buyers. As long as the future battery standard to unify, cheap and convenient way for electricity market will stimulate the rapid development of electric vehicles, battery power and then pulled up a great market growth, the number of listed companies benefit from the battery.

“In exchange for power generation as”

Liu Zhenya said the electric car business model and charge for the construction of power plants and power grid companies important to the development, according to the changing power-based, fully inserted, giving the concentration of charge, uniform distribution of the basic business model, increasing the charge for power plant layout and building.

“As soon as the company’s charge through the national model for power station construction and technical standards of the appraisal certification application in the business district. After Beijing, Hangzhou, Tianjin, Hefei, Nanchang and other cities of the electric vehicle charging network for electric construction services.” Said Liu Zhenya . Currently, the State Grid Corporation has operations in the region with all local municipal electric vehicle charging facilities signed cooperation agreement.

Liu Zhenya, appears in the “so-called electric vehicles, mainly two things, first is the battery issue, which rely on advances in technology, by new materials, new technologies and the combination of new technology, and the second is the electric vehicle operating system, is The most important part. ”

Liu Zhenya said to replace the battery-based electric car charging service model is “close to selling the car battery without the money, buy a car battery without paying money,” consumers can save money in the State Grid Corporation to replace the battery charging station . Company will also add the chip in the battery, you can monitor the battery position, the remaining capacity, remaining distance, and even notify drivers of battery power for the next position. “(National Grid Company) by night to those for low power off the battery charge. The future will also recycle the State Grid Corporation of old batteries, used as energy storage devices in the substation.” He said.

Liu Zhenya calculations: 7 yuan at current prices / liter basis, the average car fuel consumption of 10 liters per hundred kilometers, costs about 70 yuan. The electric cars cost 15-20 per hundred kilometers of electricity, even if the 1 yuan per kWh, electricity price up to 20. Electric vehicle than regular savings of 50 cars per hundred kilometers.

Equipment market quickly pull the battery

Liu Zhenya, a uniform interface standard for the entire electric vehicle industry chain lead with confidence, “no matter how cell production, and finally, the interface standard is us.” In fact, under the auspices of the State Grid Corporation of China Electricity Council was established last year to the energy industry Standardization Committee of electric vehicle charging facilities, plans to use 2 - 3 years initially established a unified national standard system for electric vehicle charging facilities.

The investment adviser that in recent years power companies and petrochemical companies are competing for dominance in electric vehicle charging stations, from the progress view, power has the upper hand, as there are various cities and provinces to establish a model electric car charging stations, and most of them choose grid as partners. The State Grid Corporation of the future will be a clear pattern as the battery charging station for the main operating mode, it is to continue to expand the lead.

Analysis, the State Grid Corporation chosen to simply upgrade to charging stations for battery-based, supplemented by the charge plug for charging power plants, power stations has greatly increased the charge for the target customer base and enhance its geographic flexibility. The shorter the time required for battery replacement, and fully automatic operation can be mechanized, charge for a relatively small area of the power station, is very conducive to big cities in the high cost of land and flexible layout. If the use of power outlets available, then the charge for power plant construction will be more convenient. In addition, the night focused on the battery charge, day delivery is also very beneficial to the State Power Grid Corporation of companies to increase the efficiency of resource allocation.

Wu Jianzhong, chairman of the public Motors, also said the model to replace the battery, remove the battery so that the cost of electric vehicles, batteries, etc. by the grid operators, this aspect makes the electric car market competitiveness, on the other hand prevent consumers bear the cost of battery maintenance.

Analysts said there is currently no uniform standard battery, each battery used in electric vehicles not the same manufacturer, size is not the same problem. If the battery standard uniform as soon as possible to solve the problem, cheap and convenient way for electricity market will stimulate the rapid development of electric vehicles, but also will greatly increase the market power battery pulled. Currently, A-share market power battery fields, from upstream resources of lithium, lithium battery manufacturers and materials, electrolyte, lithium hexafluorophosphate, diaphragms, battery management systems, sub-sectors, the key listed companies Shanshangufen, Tian Qi Li industry, Southern Power, Jiangsu Guotai, Fluoride, Fosugufen, star source materials, such as China Baoan.

1 Overview

 With the information processing technology and microelectronics technologies such as the rapid development of sophisticated, quality and reliability of power supply system demands higher and higher. Therefore urgent that a voltage stability, synchronization tracking grid frequency and high reliability Jiaoliu uninterruptible power supply, UPS power have come into being. UPS power supply is mainly AC - DC - AC conversion system. When AC is normal, after the AC to DC rectifier, on the one hand to the battery charge, on the one hand by the inverter to convert DC back to AC power to the load. When the AC power is interrupted, the battery immediately by the inverter convert DC to AC power to the load, to ensure continuity of supply. The UPS system battery is the most important, its selection and maintenance becomes very important.

 2UPS choice of battery

 2.1 Battery Selection procedure

 UPS power supply in accordance with the battery charging circuit voltage of the battery voltage used.

 If the UPS battery charging circuit power supply voltage is 110V, the value of 96V battery float voltage, the choice of rated voltage 12V battery 8. The battery discharge termination voltage Ei is 85V.

 Calculate the maximum battery discharge current Imax.

Where: P is the rated apparent power UPS power; Cosφ for the load power factor; η the efficiency of the inverter. The horizontal axis of the discharge curve and the vertical axis delay time required discharge rate of discharge termination voltage detected XC.

When calculating the number of battery safety C1.

C1 = Imax / XC (2)

The horizontal axis of the temperature curve from the minimum temperature requirements and the discharge rate in the vertical axis to look up the percentage of available battery capacity of Y.

Calculation of the safety of the final hours of battery C2,

CC = C1 / Y (3)

2.2 Calculation example

(1) the known conditions

UPS power supply rated apparent power P is 1kVA;

COSφ load power factor of 0.8;

Inverter efficiency η is 0.8;

Rated voltage of 12V battery used 8, the discharge of the battery termination voltage Ei is 85V.

(2) require

UPS power supply in the temperature range (-10 ℃ -40 ℃) in, UPS power supply for battery-powered time under the condition of not less than 1h, select the number of the battery when the rated security.

(3) The calculation of the battery ampere hour rating

① known conditions into the above formula (1) obtain the Imax ≤ 11.76A;

② The horizontal axis of the discharge characteristic curve of time-delay the end of 1h and vertical discharge voltage 85V, the discharge rate of identified XC = 0.5C;

③ the Imax and the XC value into formula (2), calculate the number of hours of battery safety C1 = 23.52Ah;

④ by the temperature characteristic curve of the horizontal axis and the minimum temperature requirements -10 ℃ 0.5C discharge rate found in the vertical axis the percentage of available battery capacity Y = 50%;

⑤ When the battery’s safety and the number of C1 and the percentage of available battery capacity into the Y value of the type (3), calculate the safety of the final hours of battery C2 = 47.04Ah;

⑥ known conditions and the use of the above requirements, the rated battery should be selected when the number of security 50Ah.

Because the characteristics of the battery manufacturers differ due to the specific use must be carried out in accordance with the instructions provided by the manufacturer.

3, the proper use of batteries

3.1 connection

Different capacities, different performance, different old and new, different manufacturers use the battery should not be linked together.

Connection, you should use insulated tools, to prevent accidents caused by positive and negative terminal.

Batteries and charger or load connection, the circuit switch to be located in the open position, the positive battery charger or the load should be positive connection, battery charger or the load negative should be the negative connection.

Connection with the nuts, bolts, washers and the connection line to be appropriately tight, even, to avoid screw loose and too tight.

3.2 Charging

Charging into the beginning of charging, normal charging, charging several balanced.

Initial charge. New battery charging as the beginning of the first charge, the purpose is to make the battery in the assembly process is the oxidation reduction electrode active material to increase the active substance content and increase the battery discharge performance.

Normal charge. Already let go of power to charge the battery as the normal charge.

Floating charge. Batteries connected in parallel with the power to the load, when AC power is normal, it will be AC to DC rectifier, the side to the battery charger, inverter, one side will be re-converted to alternating current to direct current load. When AC power is interrupted, the battery immediately after the DC inverter into alternating current to the load power supply, to ensure continuity of supply. This is called float charging the battery charge.

Balanced charge. Battery in the use of the process, often have weight, capacity, voltage imbalance. Cause the battery pack output voltage is too low, the output power is too small. To this end, over charging the battery pack, the battery pack in each single cell are in the fully charged state, the charging process is called a balanced charge.

When the battery float voltage is low or the battery needs recharging after discharge, or battery capacity is low, the need to balance the battery pack charge (referred to were charging), charging the appropriate pressure and both are necessary and sufficient frequency to ensure long life battery basis. Usually not recommended for VRLA batteries are charging, charging pressure and temperature are related. When the battery is discharged, in particular, deep discharge, whether it is used both by charging float voltage or pressure, should be aware of current limiting to prevent damage to the battery charge current is too large for the accident.

The Float and unattended, require the use of VRLA battery charger has the following features: automatic steady flow, constant current limiting, high-temperature alarm, the ripple coefficient of less than 5%, fault alarm, float / are fully automatic conversion. It is worth noting that under different float voltage ripple coefficient of the peak, 25 ℃ battery charging voltage exceeds 2.40V / only when the water will cause the battery to be broken, and the charger float voltage ripple coefficient does not match, it is possible cause the battery to increase the corrosion loss of water to speed up and leaving early battery failure.

President Obama immediately signed on Friday a new military appropriations bill. The bill requires the Pentagon to buy solar panels can only come from the United States.

 The “Buy American “provisions likely to increase tensions between China and the U.S.. China is the world’s largest exporter of green energy materials.

 U.S. leaders believe that China’s clean energy industry, given its unfair subsidies, which took the U.S. solar and wind industry trade (so to China.) December 22, 2010, submitted in such matters before the WTO, the U.S. government has decided to subsidize renewable energy in China were 301 investigations.

 The New York Times reported that the U.S. House of Representatives and the Senate under the solar panels was considered by time, and carefully written to comply with WTO requirements for China to reject the chance is very small.

 The measure also includes the U.S. government the green energy technology instruction, such as energy savings performance contracts, public services contracts, and private residential land lease contract.
