VRLAB the health status of the detection

Since the last century from 90’s to catch up with China’s telecommunications industry, large input, large output, high-tech, high starting point, as well as the development of appropriate road ahead. According to statistics of China’s 90 years in the telecommunications industry’s average growth of 44% of high-speed development. After more than ten years of development, access to telecommunications has been a relatively stable development period, but is expected to average annual growth rate of 15-20% still. The development of communication operators have access as a major business strategy, so as the access network system dell inspiron 640m battery,dell inspiron 700m battery power to support more and more cause for concern. April 1, 1995, Guangdong Shantou Jinsha electrical fire of Posts and Telecommunications Building, the direct economic loss of 14.979 million yuan; November 26, 1995, Bijie Prefecture, Guizhou Building, Post Office communications major electrical fires, 9.01 million yuan in direct economic losses and indirect economic losses 3.35 million yuan, a 50-hour interruption of communications; September 23, 1997, Zhongyuan Oilfield by missing the entire 110kV electrical substation, at the same time the disappearance of DC power. Carried out later in the battery have been detected by measuring a battery voltage of only 0.4V, resistance to 4600Ω, is the direct cause of the accident. The region’s communications security incidents took place further from the macro, global and economic point of view, from the perspective of ensuring the quality of communications, safety and property safety point of view of the battery system caused a high degree of importance.
Therefore the driving force behind equipment - power system has become particularly important. The quality of communication with the use of power directly affects the security of communication quality, communication facilities and personal safety, ranging from the impact of voice quality, disruption of communication; heavy machine building were destroyed, causing a major accident. Potential safety problems in recent years has exposed the problem, we need to take more effective measures to reverse the passive situation of extreme insecurity. In the power supply system, the most critical is the battery. Therefore, the battery state of health of day-to-day the importance of inspection and maintenance become more prominent.
I. VRLAB (VRLA) inspection and maintenance of a number of errors
The past dozen years, valve-regulated lead-acid battery (VRLA) in many different areas of application quickly. VRLA battery “maintenance free” commitment to the field in the new extension and to replace conventional explosion-proof anti-acid batteries play a decisive role. Valve-regulated lead-acid battery has been put into use, because of its maintenance-free performance, lightweight, easy to install, service life than traditional anti-acid batteries Flameproof the advantages of long and soon in the telecommunications industry and other places of UPS applications has been widely used. But whether it is domestic or foreign, valve-regulated lead-acid batteries in the course of a series of both disappointment and the users do not trust issue. As the so-called maintenance-free, and many departments to reduce the application of VRLA batteries of the battery maintenance and energy, but also for the maintenance of such a battery is often a lack of trained personnel. Reduce maintenance does not mean, however does not require maintenance, therefore, VRLA battery failure occurs instead of the type and frequency was significantly higher than traditional batteries. Traditional battery failure is the most basic positive plate corrosion caused by the loss of cathode active material. The VRLA battery has generated a lot of failure, such as grid corrosion and growth, even very prominent column cover from the battery leak caused by acid fog; excessive water loss as a result of the battery, or even dry up a series of performance caused by the problem of deterioration, such as resistance increased, thermal runaway, etc.; battery performance uneven failure in advance of individual batteries and the lack of performance monitoring and detection tools and so on. These defects have been caused by the battery at home and abroad, the use of sector VRLAB and fear of criticism.
In order to solve VRLAB emerged in the use of a variety of issues, domestic and foreign users and industry experts and scholars have carried out extensive research to improve, to make some VRLA dell inspiron 710m battery,dell inspiron 8500 battery testing and maintenance methods.
Second, traditional methods of battery capacity test
VRLA battery with the traditional anti-acid batteries Flameproof different, measuring the proportion of the electrolyte is not possible, at the same time measurement of single battery float voltage and can not correctly judge the health of the battery. Therefore, the users leave the load-discharge capacity test methods to understand the work of the state of the battery. Early adopters of capacity off-line testing method, this method should be out of the battery from the system down, connected to electric wires as a fake load, by adjusting the electric wire, so that battery to rated current of the wire electric discharge, at the same time every multimeter a certain period of time the battery terminal voltage measurement up to a monomer of which reached the provisions of the terminal voltage when the termination voltage to stop the discharge, the discharge time and discharge current is the product of the actual battery capacity. Such detection methods of measuring battery capacity value is accurate, able to clearly determine whether the battery cell failure. However, this method a number of serious shortcomings in the following:
Need to steer away from the battery system, once the test during the sudden interruption of electricity, another group of cells can lead to a separate machine oil generation? Increase the risk of paralysis of communication systems.
Cumbersome than handling the needs of electric wire, and at least one measurement of a person record data. Maintenance personnel to increase the workload and work intensity.
Individual battery terminal voltage may be measured in the interval between two cut-off voltage suddenly dropped, resulting in over-discharge.
Enormous workload test, it would be difficult to promote.
The whole group to spend 20 hours battery charge, and sometimes have to be off-line rectifier, and too easily give rise to some rechargeable batteries.
A lot of wasted electricity, giving off heat discharge significantly undermine the maintenance of staff’s working environment.
As a result of these shortcomings, the industry has also raised the capacity of online testing methods. This need not be the capacity of test battery from the system, as long as the closure of rectifiers, battery pack to allow the direct discharge of the system, while measuring the battery with multimeter monomer changes in terminal voltage. This method of capacity off-line test is relatively easy, simple and saves a lot of energy. However, this method also, there are many issues, such as: heavy equipment, the high costs (the need for special test equipment and training related to the test), there is also the process of manual measurement of certain cells of the possibility of over-discharge .
So look for an alternative to regular VRLA battery discharge test of the new method of health has become an inevitable trend.
Third, inspection and maintenance of the new breakthroughs in battery - conductance capacity test
MOTOROLA companies the United States first proposed the theory of electrical conductivity and technical basis for the theory of conductance testing technology to replace conventional capacity of the load test. Midtronics U.S. companies use the technology, designed to provide fast, safe, simple test methods to help users determine the battery status meter. Users only need to know the battery label capacity, the conductance through the test battery, we can determine the status of the battery, the test results as a battery or replace the need to pay attention to the basis.
Conductance is the ability of current conduction, conductance in the performance of battery plate for the conduction current of the battery capacity, battery plate directly reflects the state of chemical reactions, the high and low conductivity value may reflect the health status of the battery. 1992 International Telecommunications Energy Conference Papers, “Conductance and capacity of relevant research” that the principle of the use of conductance through a large number of different types, capacity, voltage, and different modes of VRLA battery connection, the use of electrical conductivity tester of capacity to carry out capacity testing. Test results show that the conductance value and the actual battery capacity, state of health showed a good linear relationship with high correlation (0.8 ~ 0.98).
The definition of IEEE standard 1118-1996: the capacity of the battery conductance measurement is known frequency and amplitude of the AC voltage at the two ends of the battery is added, and then measuring the current generated. Conductance value of the exchange with the AC voltage with the phase of the AC current component and AC voltage ratio. Significant changes in conductivity value (down more than 20%) on the mean changes in battery performance.
Such testing has been the International Telecommunications Conference and a large number of power the world’s leading communications companies to adopt, such as: British Telecom, France Telecom, Time Warner Telecom, BellSouth in Atlanta, the United States, such as NEXTEL, currently there are already large quantities of Applications, IEEE the product as dell inspiron 640m battery,dell inspiron 700m battery to maintain the equipment necessary to recommend to the user.
At present, the maintenance of the field of communication power supply capacity of the conductivity tester Midtronics mainly produced by the United States-based series, the conductivity test the capacity of the main products have the following characteristics:
Simple test and easy to carry

IV conductance capacity test applications in practice
The following is a communications company in a comparison test, respectively, the use of CTU-6000 UPS capacity battery conductance tester, with Spider1.2U analysis and capacity management software, monitoring equipment, constant current discharge capacity of the test equipment 1 32 12V UPS batteries.

Battery industry to meet the digital age

Battery is the new century, the driving force behind the electronics industry, it is widely used in cellular telephones, radio communications equipment, computers, peripherals, multimedia equipment and other fields to play. At present, advanced batteries and battery miniaturization has been the trend, digital, intelligent, environmentally friendly, and there is no battery pack protection circuit with a digital display to demonstrate its capacity and the emergence of new chemical formulations, improved production methods, developed a “smart” battery technology, developed a new type of battery measuring instruments. Nevertheless, the consumer must rely on the battery performance and assessment for functional tests. Types of domestic battery nickel hydrogen, nickel cadmium, lithium-ion battery, the main god powerful battery brands (Tianjin power of God), Jade Bird Huaguang lithium-ion battery (Weifang), good battery (Guangdong JIALI), peace Battery (Tianjin peace Gulf), Sanpu Battery (Shenyang in Liaoning Sanpu) and so on.

First, the type and technical status of the charger

At present, the charger has been advanced digital dell inspiron 6400 battery, intelligent, a variety of chargers to complete the operation by the microprocessor, can be achieved to determine the type of battery, according to the user asked to select the charge current, a variety of ways to determine a variety of protective measures Rechargeable battery capacity display, multi-channel or the order of charging the battery at the same time, the battery is full of sound and light features such as tips. This may be a constant current charging, constant current and constant-voltage pulse with a negative drop-down way, you can increase battery maintenance, the maintenance of the battery to increase battery life, and can serve as a communication adapter directly to the mobile electronic equipment power supply. Types of domestic mobile phone charger battery charger, camera battery chargers, electric automatic car battery charger.

Second, the battery and charger of digital

In recent years, do not have a direct supply of electricity power grids for mobile electronic devices have developed rapidly, which is different from the past, desktop electronic devices, can be battery-powered work. They need to shake off the shackles of power line grid, so that users can at any time convenient to carry and use. However, the development of mobile electronic devices and battery technology is inseparable from the development. On the one hand, mobile communications, mobile office, mobile entertainment products has made substantial progress, the mobile communications handsets and other mobile communication terminals, notebook computers, personal digital assistants, video cameras, digital cameras and other products become increasingly popular, Bluetooth technology, etc. objective need high-capacity, maintenance-free, convenient, inexpensive battery. On the other hand, battery technology is maintenance-free lead-acid batteries from nickel cadmium batteries to nickel-hydrogen batteries, lithium-ion battery development, the energy volume ratio, increasing the energy-weight ratio of the Light of the mobile electronic devices small, to avoid a forced distribution Using a large heavy embarrassment faced by the battery, for their “mobile” and possible.
Mobile electronic devices eliminate the inconvenience of the lead, but it also disconnects the link with the power grid, the power supply can only be completed by the battery. Although the IC Corporation, the design of electronic equipment manufacturers are endeavoring to develop low-power products, but the complexity of the function, friendly interface with other electronic devices of communication and other functions make it impossible for a very low power consumption, which is on the battery the requirements of a certain capacity, the battery-powered time or after a charging time is a very important indicator. Mobile electronic devices function on its own in terms of developing very fast, at present the vast majority have been digitized, intelligent, more or less within the control circuit to be completed by the CPU chip. Part of the power supply but it is very primitive, under normal circumstances is only provided by a DC battery to the electronic equipment, and the characteristics of the dell inspiron 5150 battery,dell inspiron 5160 battery itself, the state parameters such as electronic devices are unable to provide, even if the battery can provide their own state parameters, but the parameters of the content of communications and electronic equipment is not a unified interface coordination. This situation the design of mobile electronic equipment manufacturers and matching-based manufacturer of batteries and chargers have a negative impact.

For the design of electronic equipment manufacturing enterprises in the design of mobile electronic equipment had to be abandoned or the monitoring of the battery, do we not care about such as how long the battery will continue to use, the battery temperature, the battery life of key parameters, etc., or by the mobile electronic equipment designers to develop a set of independent battery management system, including the contents of electronic equipment parameters of the battery, communication program, the battery internal circuitry, battery charging program, thus increasing the cost of the design cycle.

Batteries and chargers for the manufacturing enterprises in the production of batteries, especially when the combination of pool and charger, had the electronic equipment of different manufacturers with different battery interface and circuit models of complex products is not conducive to large-scale production.

Therefore, support for mobile electronic devices of a cell or battery to be digitized, should prepare a public figure of the agreement battery. This agreement will integrate the design of mobile electronic equipment manufacturers, battery manufacturers and equipment manufacturers charge characteristics and requirements.

First, the design of mobile electronic equipment manufacturers, they are generally designed digital equipment, and its equipment has a computer chip, microprocessor chip, digital signal capable of communication control. As long as the batteries have digital interfaces, equipment and communication between cells, control can be completed by the equipment, and some even can not increase the hardware cost, increased by only some of the procedures will be able to easily read the parameters of the battery and display to the user. Can be seen that as long as there is uniform agreement on the design of electronic equipment can also be used as the basis for the design of the power of a large number of power-saving part of the design work and shorten the design cycle. In addition, because the dell inspiron 6000 battery,dell inspiron 630m battery interface is standardized, electronic equipment manufacturers may also choose a different battery supplier with a view to get the best service and prices.

Secondly, for battery manufacturers, battery manufacturers as a result of the main basis of knowledge in electrochemistry, the electronic circuit and experience of personnel is relatively weak, respectively, for different users with different design, digital battery, it will be difficult. If there is a unified digital agreement, self-developed or commissioned by other companies to develop digital batteries, less input and quick results, as well as a battery to improve the value-added products.

Third, the battery charger manufacturers, their products will be mainly into voltage can be used to recharge the power supply, control of battery charging and stop charging, given the work of the charger, and battery status display. At present, the charger has been advanced digital, intelligent, a variety of chargers to complete the operation by the microprocessor, can be achieved to determine the type of battery, according to the user asked to select the charge current, a variety of ways to determine a variety of protective measures Rechargeable battery capacity display, multi-channel or the order of charging the battery at the same time, the battery is full of sound and light features such as tips, can be a constant current charging mode, constant current and constant-voltage pulse with a negative drop-down way, you can increase the maintenance of cell functions, maintenance of the battery to increase battery life and AC adapter can be used to directly power mobile electronic devices. Uniform agreement dell inspiron 6400 battery of digital products will help to reduce the number of species, the relative increase output and reduce prices accordingly.

In short, the unified digital battery agreement will benefit all of the vendors in the market to achieve win-win situation.
