Electric bicycles pollution dispute

Last March, the Ministry of Public Security and other four ministries jointly issued a "sub-standard order, requiring remediation electric bicycles. May, nine ministries and commissions of the Ministry of Environmental Protection and other remediation of lead-acid battery industry, many lead-acid battery enterprises to stop vostro 1310 battery production or close, the electric bicycle industry into the development of the plight.It is understood that last year's "rectification" of the entire industry is really a great, Some companies shipping cars can be coupled with a battery, low battery, resulting in vehicle operations difficult to carry out.

Countries for "rectification", mainly for non-compliant enterprises and products, not the entire industry shut down. Inadequate investment in environmental protection equipment, there is no environmental assessment or perfidy sure to be remediation processing.

However, the quantity of batteries gap "rectification" for new upstream businesses closed up also tens of thousands, year by year, the figure of one million group of  Inspiron 1501 battery needs small in comparison. More importantly, the new day and upstream suppliers to establish long-term strategic supply agreement, the years of trust, you can ensure adequate supply. At present, lead-acid batteries all purchased from upstream.

Ensure battery safety approval, has been with a view of the electric bike there may be a pollution problem. Some people think that the First, the battery will control the pollution problem in production. In addition, lead-acid battery power larger itself volume, 70% lead recovery of a battery of one hundred dollars, so it has the characteristics of recyclable, there is little user carelessly throw inspiron 1720 battery away. And motorcycles, cars, electric bicycles, energy saving and environmental protection features.

After calculation, an electric car driving for 20 kilometers per day, 1-year total cost of use was 956.18 yuan, power consumption of 87.6 degrees to 31.54 kg of standard coal in power generation converted into petrol is about 28.99 liters, emissions of 315.4 cubic meters. Traveling the same distance and time, the total cost of a motorcycle for 2585 yuan, the consumption of gasoline to 182.5 liters, 1825 cubic meters of exhaust latitude e4200 battery emissions, and a mini-cars (0.8L displacement) the total cost of 10,143 yuan, gasoline consumption is 365 liters emissions from 3650 m3.

Health care, emphasis on lead-acid battery recycling

 Toxic and hazardous substances accounted for the majority of the composition of the lead-acid battery electrolyte sulfuric acid accounted for 16 percent of leaded substances accounted for more than 70% of these two substances on human health great harm.
It is reported that the total production of lead-acid batteries in China, in 2006 approximately 72,414,000 KVAh, after the past few years an increasing trend. Into circulation of lead-acid pt434 batteries from the production, use, waste link, the hazards to humans and the environment will inevitably increase.

It is understood that a lead-acid batteries can be sold for 100 yuan, no one will lose, and are sold directly to small traders, most lead-acid batteries "outcome" is that the individual sold to small traders, small traders and then these waste lead-acid batteries sold to small smelter.

Lead-acid batteries have done great harm to humans and the environment, the face of the current lead-acid battery market recovery, the relevant departments should take measures to deal with recycling latitude d520 battery issues.

First, the relevant departments should rationalize the lead-acid battery recycling mechanism, the establishment of the lead recycling qualification examination system. The face of the relevant departments of the small traders in the recycling chain should be the introduction of recovery mechanisms and the quality audit system be investigated and dealt with the recycling chain improper prohibited waste battery recycling.

Second, focus on the development of recycling industry backbone enterprises. Meet the qualification requirements of the enterprise to the public directory, a virtuous circle. Recycling business, to build a strong strength of strong strength of the recovery of well-known enterprises, and eliminate consumer waste  studio 1735 battery bought for small traders.

Finally, the relevant departments of propaganda work, so that consumers understand the environmental hazards of waste lead-acid batteries, and consciously with a good lead-acid battery recycling.

How to Test the Battery Power ?

Detect ordinary zinc-manganese dry battery level is sufficient, there are usually two ways.The first method is by measuring the battery instantaneous short-circuit current to estimate the internal resistance of the battery, and then judge the adequacy of battery power; The second method is an appropriate resistance resistor in series with ammeter, calculate the battery by measuring the  Inspiron 1545 battery discharge current resistance, in order to determine whether the battery is sufficient.

The biggest advantage of the first method is simple, with a multimeter the current file can directly determine the dry battery power, the drawback is that the test current, far more than dry batteries to allow the discharge current limit, to a certain extent the impact of dry vgp-bps13 batteries. life expectancy. The second method has the advantage of small test current, security, and generally do not have a negative impact on the life of dry batteries, the drawback is a bit trickier.

I use the MF47 multimeter to a new No. 2 batteries and an old dry cell using the above two methods to test contrast. Assume that ro is a dry  hp g70 battery internal resistance, RO ammeter internal resistance, the second test method, the RF is the additional series resistance, the resistance of 3 ohms, the power of 2W.

The measured results are as follows. New on the 2nd  hp g62 battery E = 1.58V 2.5V DC voltage profile measurements, the voltmeter internal resistance of 50k ohms, is much larger than the ro, it can be approximated to that 1.58V is the emf of the battery, or open-circuit voltage. The first method, the multimeter set 5A DC current file, meter internal resistance RO = 0.06 Ohm, the measured current of 3.3A. Ro + RO = 1.58V ÷ 3.3A ≈ 0.48 Ohm, ro = 0.48-0.06 = 0.42 ohm. The second method, the measured current of 0.395A, the RF + ro, + RO = 1.58V ÷ 0.395A = 4 ohms, current 500mA file internal resistance of 0.6 ohms, so ro = 4-3-0.6 = 0.4 ohms.

Old on the 2nd  latitude e4200 battery when the first method measurements, first measured the open circuit voltage E = 1.2V, the meter internal resistance RO = 6 ohms, a reading of 6.5 mA, a multimeter set to 50mA DC current file, ro + RO = 1.2V ÷ .0065 A ≈ 184.6 ohms, ro = 184.6-6 = 178.6 ohms. The second method, the measured current is 6.3 mA, ro + RO + the RF = 1.2V ÷ 0.0063A = 190.5 ohms, ro = 190.5-6-3 = 181.5 ohms.

Obviously the two results of the test method is basically the same. The final calculation of small differences due to reading error, resistance caused by the RF error and the contact resistance and other factors, this small error would not affect the judgment of the  latitude e5400 battery power. If the measured battery capacity, high voltage, you should adapt to increase the resistance of the RF.

New iPad ignited a wave of large-scale polymer battery

Apple's new tablet the new iPad has been launched, the terminal market, the components of price impact is gradually fermentation; according to DRAMeXchange (TrendForce)'s Green Division Energytrend research surveys, large polymer lithium battery as the The upgrade of the system power specifications and market demand, the associated unit price of the battery cell into a more reasonable price to the amount of system situation.

Energytrend pointed out that the awaited new iPad In addition to using the previous generation and the same polymer battery, in order to meet the need of high-resolution panel, 4G high-bandwidth transmission of power-hungry components, the battery core increase capacity from 2300mAh to 3800mAh, increase capacity by as much as 65%. Polymer battery in the product specification has always been the custom of the phone from the early start, because the small amount of various characteristics of the supply capacity part of a value to a conservative view. With the hardware in Apple's new products to follow the trend, the future of mobile phones and flat-panel system power consumption is bound to increase, caused the polymer needs more dramatically.

System design, the new iPad battery pack design is still a series of three parallel mode, is not a large difference in battery protection board, battery assembly yield the above roughly will also increase the difficulty, the whole The battery cell plant is still a profitable product trends.

Apple ignited a wave of large-scale polymer battery driven, the new tablet and ultra-pole of this (Ultrabook) the demand for large-scale polymer lithium batteries also will be buoyant; characteristics of the process, large and small lithium batteries differences is not high, the key lies yield more thin, EnergyTrend to understand the current large-scale polymer lithium batteries have not been caused by the bottleneck capacity.

To the second quarter of 2012, supply and demand point of view, EnergyTrend launched new models of tablet devices with ultra-pole of this can be seen on the demand side pull changes, improve the utilization of the battery product line, but also because so large polymer battery prices began to produce more price decline.

Basis of DRAMeXchange technology survey, because many manufacturers of new products is the first new open case stage, the current production has not yet generate crowding out effect, sufficient capacity can go due should demand, and therefore short-term needs are driven by the price decline is limited, production number pulled, and even capacity is tight, have a chance to cause further price reversal is estimated in the second quarters of 2012, the situation will be clearer.

The Photovoltaic Battery Industry

Photovoltaic boom in low-end of, but is also seen as a time when technology research and development, the practice of the golden age of technology the focus of concern in recent cross-strait industry, that is almost a year many international equipment industry continue plans to introduce metal back passivationlayer (backside to passivation) techniques and equipment, the technology in addition to the module side can inherit the current welding technology, efficiency, increase the Inspiron 1545 battery space is expected to reach 0.2 to 0.5 percentage points, however, the equipment industry in the production yield and cost optimization of client considerationsnot impatient launched.

Photovoltaic although a time when the economy low, however,it is the technical sophistication of the active period, the solar industry reports that the moment is to create the golden age of vgp-bps13 technology, competitive differentiation, prepared by the various industry is the battle of the next boom reversed effective use of differentiation to throw off other competitors.

Recent equipment market actively unite the launch of the new technology, that is, the metal back of the passivation layer (backside to passivation), the solar industry explained, the technology is the the AL2O3 film as a P-type solar photovoltaic cells on the back of the passive film or the N-type battery electronic and electrical safety to reach the front, the main purpose is to let the sun in the Inspiron E1505 battery circuit, and not like other technologies like both combined with out the reach and therefore the circuit is blocked, which will make the cell conversion efficiency and thus enhance the This article from the new portal of solar photovoltaic.

The solar industry on simple solar photovoltaic cells, the basic process (base line) point of view, the laboratory, a single increase in the metal back of the passivation layer, you can make the battery is 0.2 to 0.5 conversion efficiency percent, said the solar industry, important that the back-end heritage present a large number of modules and welding technology, no need to make any changes, this is one of the reasons to attract the two sides of Casio NP-20 industry, of course, the Taiwan-based plant-based battery OEM more heart.

However, the import of the technology is expected to increase three to five production station, the consideration of mass production yield is one of the key, so equipment manufacturers to enhance the Fujifilm NP-100 technology and equipment coupled with the technology research and development of the solar plant will affect the success or failure, which is the cross-strait solar plant concerned about one of the major equipment manufacturers launch devices.

The energy storage achieved industrialization

Reduce storage costs, the key is to break the security of the energy storage battery, cycle life problems.To well-off that the breakthrough of these technologies is the premise of the energy storage to achieve industrialization, but the NB-2LH battery technology matures it may take many years, pessimistic look likely to exceed 10 years.

The Zhangbei demonstration project uses the lithium battery technology is able to represent the future direction of development of energy storage technology is still controversial.Yu-Sheng Yang, Chinese Academy of Engineering, believes that although the lithium-ion battery with high specific energy, high power, high energy conversion efficiency, long cycle life, etc., but the technology is currently higher prices, more importantly, safety is still quite poor, while most important for power system security.He, China Southern Power Grid energy storage demonstration projects lithium-ion nb-5l battery pack had to smoke 22 times.

A wide range of energy storage battery technology, according to incomplete statistics, the energy storage according to the needs of different areas of 12 kinds of different technologies.?It is understood that the the Zhangbei 20MW energy storage demonstration projects in addition to the 14-megawatt lithium-ion battery technology, the 2MW flow Casio NP-20 system, while the remaining 4MW of energy storage which battery technology, the State Grid yet conclusive?.?It is reported that the 4MW of energy storage was originally left to the sodium-sulfur battery technology in Japan, the technology accounted for more than 65 percent of the global energy storage applications projects.But, according to Yang Yusheng, sodium sulfur battery with high specific energy, conversion rate, the advantages of longer life expectancy, but not safe, the use of sodium sulfur battery technology energy storage power station in 2011 has twice the fire.

"What kind of energy storage technology is not the key." To a well-off, of Zhangbei the storage demonstration projects designed for the energy storage business to provide the future direction of high security, long-life.?The country is currently engaged in energy storage related companies.?According to Yu Zhenhua, and storage-related businesses include a variety of battery manufacturers, and control of inverter manufacturers, application solutions provider, enterprise project, the current lead-acid Casio np-30 battery manufacturers, lithium battery manufacturers, control inverter manufacturers as well as some of the key materials.manufacturers are relatively mature, in addition to other energy storage technologies there is no scale.


Due to lack of core technology research and development of raw materials, domestic battery enterprises in the processing stage.According to industry sources engaged in lithium domestic energy storage does not scale, domestic battery in the procurement of upstream raw materials can not form a bargaining power, so the battery core raw material prices are much higher than their foreign counterparts, the last only by purchasing localization accessories reduce the price of the energy storage system.

To believe that a well-off, domestic battery most of the enterprises to start from the OEM, even if the storage size increases it is difficult to really benefit.To open the lower reaches of space, enhance the bargaining power along the high safety, long life, low-cost direction to increase R & D investment, rather than build more production lines.The current global Fujifilm NP-100 battery storage industry has just begun no later than domestic enterprises at this stage intervention.
