Rechargeable laptop batteries have exploded

Rechargeable laptop batteries have exploded

For most notebook battery for business use, there will be a special hardware and software designed to protect the notebook stability and security, especially in the software design will have special security to prevent viruses. However, a recent Internet-virus software company KASPORSKY recently issued a warning, there are a so-called "Blueyes" (Blue Eyes) notebook virus is widely disseminated through the Internet! The virus does not invade the bad data in the notebook, but special attacks notebook batteries, once activated will cause an explosion or burning laptop battery!

It is learned that the "blue eyes" virus is the common hardware and software completely harmless, it is disguised as a feedback information packet, through the TP / IP network to send the interactive mode. As a result of this information packet does not have any offensive capability, the current firewall and antivirus software can not seem to be killing.

However, for notebook ibm batteries users, "blue eyes" is very dangerous. The completion of charging the battery when the notebook when the transformer through the software to send a signal to remind the end of charge, into float mode. "Blue Eyes" will be the signal to activate, it will retain this information sent to the system "to continue filling fast" signal. At this time will speed up transformer for the laptop battery, notebook battery so that in a very short period of time, excessive charge, which damaged the notebook battery, or even cause an explosion. At present in Russia and Europe have taken place in a number of notebook batteries burning incident, the office of a bank in the Netherlands notebook in standby cases of spontaneous combustion, it was initially suspected to be "blue eyes" to make trouble.

The software company said that although there is no antivirus software can be killing the virus, but there are still ways to avoid damage to the notebook battery:
1. Not in the boot state charge, "blue eyes" virus WINDOWS system environment can only be activated when in the DOS can not afford to shut down or no role at all;
2. The work of state is best not to use an external power supply, use only the battery, which can persist for some 1-2 hours for the notebook user models is undoubtedly bad news;
3. Headroom laptop battery is always kept in mind shows that if the rapid increase in electricity consumption, a long time to immediately shut down or unplug the external power supply;
4. When they find out too much heat when the keyboard, it is necessary to promptly check the remaining battery power

The next two years to support new energy projects introduced special

To promote renewable energy and new energy technologies and related industries, National Development and Reform Commission recently announced between 2005 to 2007, will focus on supporting the new energy of the special field of high-tech industries and special projects 92p1073 battery, 92p1075 battery, including five major areas and related projects .

These five areas and related projects are as follows: First, wind power. Carried out 1.5 MW VSCF wind turbine and 1.2 MW direct drive permanent magnet wind turbine industrialization. Second, solar photovoltaic power generation. Carried out using silicon solar ingots / wafers, as well as high-performance low-cost solar cell components and system control components of the industry. Third, solar heating and ground source heat pump heating (cooling). To carry out a new type of solar water heaters and ground source heat pump systems industry. Including high reliability, the new vacuum tube collector, a large area of high-temperature solar water heating systems, solar water heating systems all-weather, high-performance ground-source heat pump and its supporting systems. Fourth, high temperature gas cooled reactor demonstration power plant. Temperature gas-cooled reactor demonstration power plant to carry out the design of research on critical equipment (helium blower, pressure shell, etc.) and materials (graphite core material) for the development of industrialization. Five or hydrogen energy. To carry out the preparation of hydrogen fuel, storage, exclusive of the fuel cell industry. Including the preparation of a new generation of coal hydrogen technology, hydrogen from natural gas technologies, high-pressure hydrogen storage tanks, fuel cell vehicles, fuel cell power plant fixed.

It is understood that the basis of the relevant enterprises to declare the principle of development around the National Development and Reform Commission to declare the special funds, special funds each year to apply for a focus on the admissibility of the report, the annual deadline for applications is May 15. Declaration of a special fund in the declaration, to the need for an analytical report issued by the project, the project analyzes the technical basis of the report, building programs, environmental protection and energy saving measures, the basic situation of the project legal, investment plans, project financial analysis, economic analysis and the main indicators for banks loan documents and other related materials.

The United States successfully developed a new battery monitor

Equipment and Instrument Texas researchers have developed a reliable battery monitors, the monitors can accurately measure the remaining battery capacity, up to 1% accuracy. Each battery pack contains a two-chip system, is responsible for continuously calculating the remaining capacity. Chip set has also taken into account as a result of the use of length and temperature conditions of use changes in the impact resistance of the battery.

Based on accurate models of lithium-ion chemistry, the chip through the impedance measurements to adjust the remaining battery capacity of the forecast. Introduction of new technologies will be carried out in mid-2005.

The new monitors can be in the digital camera, MP3 player, mobile phone, as well as widely used in notebook computers. A typical notebook computer system within a microprocessor chip, to monitor battery charging and discharging situation, by running the software to predict the remaining 92p1077 battery, 92p1087 battery capacity, but the monitoring process and can not be sustained, nor real-time monitoring, even greater errors.

Therefore, the battery must be in a certain range of environmental conditions of work. Battery working hours and performance vary depending on storage conditions, temperature and the use of means, such as the pace of battery discharge, the use of long and other factors. Internal changes in the performance of batteries in its resistance changes, it determines the battery life.

Texas Instruments equipment was the company's chip design to take into account the battery temperature, battery current and battery voltage recovery time and other factors. The battery monitor will continue to track the battery's "state of health."
