Battery-line monitoring program

November 8th, 2009 admin No comments
First, an overview of battery

Valve-regulated lead-acid battery “VRLA” (also known as maintenance-free battery) as a back-up power supply in various fields, the extensive use of the surface sense of the maintenance-free. As the power industry and the telecommunications industry base stations, substations and other fields increasingly high degree of unattended, resulting in all kinds of batteries in the course of problems. Such as: electric power system minutes / closing operation failed or UPS failure, the communications industry breakdown in communications, and so on, will have serious consequences. The traditional methods of battery maintenance takes a lot of manpower and material resources on a regular basis for testing.

ZJK3-B Series battery monitoring system is mainly used in various industries for remote monitoring of battery, so that staying at home and can always understand the different batteries on-line running. Power DC operating power supply, communications, power or large capacity UPS systems are used by more than just a concatenation of the accumulator battery. Since the battery used in tandem, when either a battery failure, may cause the entire battery pack does not work.

To prevent accidents, DC power system equipped with multi-compaq laptop battery tester. According to test theory can be divided into the following categories:

1. Judged by measuring the internal resistance of battery performance battery

This method must be discharged battery pack can not be used in-line continuous monitoring. And the battery internal resistance with ohm impedance and electrochemical impedance reflects a variety of factors, measured under different conditions of battery internal resistance vary greatly, it is difficult to make accurate judgments on the battery performance. And measurement principles of complex and costly.

2. By measuring the battery terminal voltage to determine battery performance 

This method is easier to achieve cell-line inspection. The battery terminal voltage and batteries are the relationship between electric potential and resistance, measuring the battery terminal voltage comparison can reflect the actual state of the battery. Produced using this principle battery inspection device in the power system has been widely used. But the measurement of each battery terminal voltage must be on the connection, when the cell number of more or distance, it will use a lot of sample cables, installation of wiring complexity, and the quantity likely to cause ground cable or short circuit accident. Thus the method is used for the following 18 test battery.

New energy: battery shipments to increase Vs polysilicon prices

September 29th, 2009 admin No comments

Battery-line network June 8 hearing battery shipments decline in the price recovery and polysilicon solar energy industry in May is undoubtedly the most noteworthy of the two signals; from our observations of the situation and dealers, in May batteries a substantial increase in shipments of chain, some companies have experienced growth year on year data, this is exciting news. Volume increase was mainly dependent on three factors: the gradual installation of season began, bank credit, slow recovery and the continued uncertainty of national policies, which coincided with the fourth quarter of last year, in contrast to the industry predicament.

April began in Europe, especially Germany, the end of winter, outdoor construction of a fresh start, the demand for components will naturally become restoration; some European banks began to slightly relax the restrictions on solar energy credit. This aspect is the last wave of bank failures, banking Buzhi Yu fear can hardly protect themselves, it began to gradually restore credit; On the other hand, the global scope of the new energy and solar energy advocacy for banks and credit approval of personnel executives have a direct impact.

According to the current situation to determine, if no accident, this year’s global compaq evo n600 battery shipments to achieve positive growth in the probability of large, and this is our point of view has been upheld. Need to be reminded that, due to the price fell, revenue will decline in the size, of course, the specific price range need to look behind the recovery of the battery; and battery shipments rose steadily the situation is different, as the solar cell of the most important raw materials, the price of polysilicon is Diego to new lows, the current mainstream product prices in the 50 to 60 yuan / ton level, leaving only a fraction of the price of a year earlier, in the current price of this, some companies have high cost for little or do not make money, on the contrary in accordance with the current polysilicon prices, the downstream components of the battery, and space is improved corporate earnings, which in contrast with the previous two years; appear to increase cell volume, but the reasons for polysilicon prices remains a structural imbalance between supply and demand.

While the compaq evo n600c battery out of a significant increase in the volume of the chain, but only flat year on year, but shipments of polysilicon there is substantial growth year on year, coupled with dealer inventory factors and factors, it is not hard to understand dramatic price fluctuations; from the whole years as well as the perspective of the next two years, polysilicon supply and demand does not appear one-sided pattern of excess, does not appear pessimists price is equal to variable costs, we view the industry experiencing volatility gradually move closer to the bulk chemical properties of raw materials , the winning companies need to have three characteristics: large-scale, technology, slightly ahead, low-cost.

From the demand perspective, if the terminal needs to achieve positive predictive value, and a basic balance between supply and demand of polysilicon may even have a small gap from the current situation, the terminal is expected to exceed demand for the next two years is very likely; the supply side, step by step down the price of making a lot of planning to enter the industry, investors began to shy away from our current knowledge of the situation, such cases are not isolated cases, which makes the supply of the compaq evo n610c battery next two years will be less than the current estimate. Has gone through a harsh winter, spring has been rushing toward us, though still slightly chilly.
