Currently, the battery testing and monitoring has gradually become a hot topic, power systems, telecommunication systems, systems of mobile communications industries and other information are all tests of the Laptop battery and monitoring progress relevant requirements, the major manufacturers to actively develop the products concerned.
Information security and security of electricity supply point of view, battery monitoring and battery itself has the same importance. In the highly modernized society today, it is difficult to imagine the power grid electricity, telecommunication network to the social, political paralysis and economic losses. To avoid such losses in the corresponding devices use batteries as a source of backup power, so that even if a power failure, but could easily adopt other emergency measures to prevent occurrence of losses. As with other electronic components, batteries, as there is problem of early failure, but the battery there are still problems correctly, the IBM 40Y6799 battery monitor in these two aspects is to improve system reliability, which means hand One, the monitor can cause the battery in the right running the state, secondly to monitor the failure of the battery can be found soon. Thus, the battery to control the safe operation of critical systems has an important meaning.
Battery monitoring is not new, its history almost as long as the history of lead acid batteries, but because of electronic technology and information technology to give only one injection of new concepts. From a user perspective, only the battery voltage and battery current monitoring of these products have been unable to meet its needs, with single monitor cell voltage has an internal resistance of a battery and follow the product is increasingly used. On the other hand, new technology has been widely adopted, the relay contacts to switch gradually disappear replaced by electronic switching batteries advanced technology single-chip to monitor the product has a powerful feature, signal processing to enable digital tracking of products with higher accuracy and reduce costs. A variety of applications in this area so that a new generation of Dell Latitude D810 battery monitoring have improved continuously from all angles.
Battery users are more concerned about the battery monitoring products can meet the security requirements of their application. The battery on the market products is not able to monitor user satisfaction. From the results of national research and foreign, outside voltage single cell monitoring to detect a short-circuit the battery and the battery of this type of battery failure, the decrease in hard to find pairs of battery capacity, reduced battery capacity was the main failure mode of the battery, only the resistance of the battery’s internal monitoring may indeed find these batteries.
Product performance and cost is that the user is most concerned about two issues. Operating parameters on hp Pavilion ZE2000 battery monitoring products on the battery pack a big help for the smooth functioning of the battery has not been detected failure of basic capabilities with a single product stack voltage monitoring can be found as the cell types of short circuit and open circuit the battery cells such as for serious offenses on the battery capacity decrease little or no detection capability, an internal resistance of the battery monitoring products to meet requirements for high security application requires. Operating parameters on battery monitoring products with the lowest cost, most single cell voltage monitoring products have a lower cost, has an internal battery resistance monitoring, higher commodity costs. There are also specific needs of users of large volumes of high-performance products available for selection. As the security of application systems, the system can not still under maintenance, on-line monitoring to better meet this demand. On-line monitoring can also improve efficiency, more accurate and reliable completion of the tasks of monitoring battery. Battery monitoring networks and have a close relationship. In addition to software, network security, system management and other issues, but also a close relationship with the material, while monitoring the battery is a key factor should be one of the issues. On the other hand, in view of automation of surveillance, monitoring network is electricity, the characteristics of the communications industry, which requires monitoring of battery products with network compatibility.
