Why Do Battery Calibration Feature Makes Capacity To Restore Part

Sept. 27, 2009 - PRLog -- 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; 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, http://www.bestlaptopbattery.co.uk/asus/a2500h.htm 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. http://www.bestlaptopbattery.co.uk/dell/precision-m70.htm    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, http://www.bestlaptopbattery.co.uk/dell  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.  
  Battery calibration function is to balance the multiple batteries, the battery because of their resistance can not be completely consistent, the battery

will be great resistance bear strong current, leading to their own consumption more than other batteries, but also easier to wear and tear, therefore, on a

regular basis to do the battery calibration is necessary - so as to balance the burden of multi-cell "work", thus extending the overall life expectancy.
