How Is The Correct Battery Charger?

Oct. 7, 2009 - PRLog -- In the notebook computer batteries, as well as a large responsible for managing these batteries housekeeper -http://www.bestlaptopbattery.co.uk/acer/bt-a0201-001.htm
power computing chips, which is the management of battery, computing power, is responsible for charging and discharging of the "responsible person."
In the measurement of battery technology, there are four kinds of common method, but not books of different brands of batteries using only one method of calculating power consumption are usually several ways to use an integrated, in one of the main method of calculating The remaining auxiliary calculation means to achieve the computing power to manage. The first is the open circuit voltage measurement method, this method is by measuring the battery voltage in the stationary state values to calculate the remaining battery capacity, but because of stationary lithium-ion battery voltage and remaining capacity of the relationship between the non-linear, Therefore, this method is not an accurate measurement of the value of the vast majority of cell phone batteries have adopted this method of calculation; http://www.bestlaptopbattery.co.uk/acer/btp-44a3.htm  the second is called Coulomb's method of calculation, the method is by measuring the battery charge and discharge current, the current value and time value of the After the product is calculated by integrating the batteries into the battery charge and the release of electricity, Coulomb's method of calculation is a more accurate method of calculating power; third is to impedance measurement method, it is by measuring the resistance within the battery get the battery remaining capacity value; The fourth is a comprehensive look-up table method, by setting a related table, the voltage, current, temperature and other parameters input, you can check the battery's remaining capacity to be. Thus, apart from the internal structure of the battery batteries, there are management chip, the chip contains one or two of them measuring method of calculating capacity batteries, and a set of charge and discharge protection circuit. Among the notebooks in the system, through the driver interface access to this chip, and then set the battery management.  ? So, why the battery would be more you use less electricity, but the implementation of the correction function can restore the battery capacity of a part of it? Laptop batteries are generally the so-called six-pin power, 4-pin power, refers to the number of battery cells within the batteries. So many batteries together, that is, the less electricity more you use the fundamental reasons: batteries and the batteries between the quality of discharge can not be exactly the same level, such as discharge, in which a substantial reduction in power batteries, In order to maintain voltage stability, battery management chip will follow "casks principle", according to the worst of that energy-saving core to charge protection, battery charge will naturally decline, the impact is even more than the battery irreversible Institute of Chemical Physics change.  http://www.bestlaptopbattery.co.uk/acer/ms2111.htm
