Use of abundant solar energy resources in the development of solar cell industry is of great significance. It is not only one of us to develop new energy mandate is to expand new energy diversification and sustainability of the open!
Currently without forming photovoltaic product standards, resulting in uneven quality of PV products. Photovoltaic technology is key solar components. Solar cells in series can be formed after the package to protect a large area of solar cells, coupled with the power controller and other components to form a photovoltaic device.
As the solar PV industry is unique, from ingot to the component, the output of each production processes can be used as products enter the market, the battery is the case. Battery quality is good or bad, directly affects the performance of components, so an urgent needs to develop solar cells on the product standards to ensure the battery quality, so as to guarantee product quality components.
- Storage Battery to Become the Main Source of Income
- Company realized operating income of 1.668 billion Yuan, up 36.43 percent, to achieve operating profit 33.327 million Yuan, net profit attributable to shareholders of listed companies 27.065 million Yuan, respectively, an increase of 174.78 percent and 219.74 percent.
Faster revenue growth, gross profit margin fell slightly. Company in the first half operating income 1.668 billion Yuan, up 36.43 percent, car battery production and sales volume reached 4.83 million, respectively, and 4.94 million, but operating costs increased by 39.17%, slightly higher than revenue, the company's consolidated gross margin was slightly down 0.85 percentage points to 11.37%, of which the battery product gross margin 11.69%, down 1 percentage point. We believe that growth in the first half year performance of the main beneficiaries of substantial growth in car sales, car sales in China were completed during the first half 8,927,300 and 9,016,100, respectively, an increase of 48.84% and 47.67%, but the car is worth noting that in recent months chain sales declined year on year growth rate started to slow down in the second half growth may slow down performance.
Battery business income accounted for 91.60%, the slow development of other businesses. Battery business has been the company's main source of income, in 2008 accounting for 85% of income, then increasing every year. The current car to start with a lead-acid battery production scale of 10 million, while there are 5 million construction maintenance-free sealed lead-acid batteries, is expected to reach capacity by the end of 2011. Industrial lead-acid battery production capacity 1 million KVAh, the company's own capital to build 3 million KVAh still under construction, is expected to reach capacity by 2012. Lithium project operation is still not ideal, loss of 6.36 million Yuan; the main problem is low quality standards. Is a lead-acid battery industry's leading enterprise segment, but development of the industry point of view, the new battery on the battery replacement is inevitable, the company must be in a stable where the main industry, and actively develop new battery, to open up new profit growth point .
Mineral resources may be a surprise. The company bought in 2007 Hongling word and County South section three exploration, preliminary survey of the gold reserves of 10.2 tons, 1550 tons of silver, lead, zinc total 870,000 tons, of which the word and Hongling has commissioned a detailed survey professional exploration agencies, but not the results, mineral resources, future company performance may be a surprise.
According to our earnings forecasts, without considering the value of mineral resources from 2010-2012 EPS was 0.17 Yuan, 0.23 Yuan and 0.25 Yuan, the current stock price times the corresponding PE were 86,63,58, giving neutral ratings.

- Modern Storage Battery Test
- Modern battery testing methods, the current popular through the intelligent discharge, test resistance to determine the battery situation. Resistance measurement method used to determine the battery is good or bad, it just uses the battery when the stage performance is more stable and accurate, but the use of batteries for some time and then testing will be a great error, and even judge allowed the main The reason is that the battery manufacturers in the technical limitations, resulting in large differences in the use of materials available to users of battery internal resistance is very error, although large differences in resistance, but the use does not affect the capacity and voltage, because the voltage and capacity is a direct reflection of the importance of good and bad performance battery, which work in the years of practice has been proved, sometimes from the fact to see is not necessarily a bad battery internal resistance of large, sometimes even Panduan also can not give correct standard of maintenance of way, more let alone solve the problem, and even they can not change the batteries in case of continued use, which to some extent, damage to the battery life. Therefore, resistance testing methods can not completely reflect the real situation of the battery; no battery maintenance to what convenience, from an economic standpoint there is any cost savings.
So intelligence is our battery maintenance discharge instrument the most appropriate instrument. I produced the BPS, BTS can be effective in the battery testing and maintenance, greatly improve the efficiency and effectiveness, saving maintenance costs, making maintenance simple and easy change, acceptance of battery effective instrument. And because a group of battery capacity is lagging behind by one single minimum capacity of decision, so when we had the smallest backward battery, you need to know exactly how capacity, and future maintenance of special attention in order to understand the whole time Group battery situation. Vortex Flow meter
Battery tester contrast that the entire group of the traditional method of discharging the battery working strength is not suitable for frequent and can not be repaired on the monomer. But now when we find behind the single, you can use BCC smart activation of backward single battery meter fix in order to enhance the capacity of Jinxing capacity, to prevent further deterioration of the battery as well as affect the battery performance of the entire group. I produced the BPS, BTS, BCC series of comprehensive maintenance and battery maintenance equipment is adapted to the needs of China's power industry development and the development and production. It is a total of five series, hundreds of models, widely used in electric power, telecommunications, railway, metallurgy, chemical industry, finance, data networks, automatic control and many other fields.
