The secret of laptop battery


Some time ago, Apple, Dell, Sony, HP and other PC problems with a giant laptop battery internationally known, which included the original in mind? Today I want to look also to talk about your laptop battery to share some information with you?



Why laptop battery more to consume less energy? Why stop charging the Dell latitude d531 battery back part of the repair function? How exactly the right charger? All of this calculation is beginning to charge the battery.
Removed, or batteries, nickel metal hydride, lithium-ion batteries are used, or not widely lithium polymer batteries, or even the rising stars in the silver-zinc batteries, they are responsible for warehouse storage of electricity, the difference is their access to the library path of the storage capacity alone. Laptop batteries, as well as Vice President of these large batteries - power computer chips, is to manage energy, computing power, is responsible for loading and unloading "in charge".



Measuring the battery technology is a 4 common methods, but the books do not mix different brands of batteries by using only one method of calculating power, usually several ways to use the integrated one of the main method of calculating the support means to achieve the calculation of energy management. The first measure the open circuit voltage, the network is to measure the battery voltage at steady-state values to calculate the remaining energy capacity, but because the voltage of a lithium-ion HP pavilion dv2000 battery capacity remaining and the rest of the relationship between the non-linear, so this method does not measure the value of the vast majority of mobile phone batteries have adopted this method of calculation, the second is called the Coulomb calculation method is to measure the load and the battery discharge current, the current value and time value is calculated by integrating the product the battery after the charge and release the power of electricity, Coulomb's method of calculating a more accurate power calculation, a third measuring the impedance, is obtained by measuring the resistance of the battery remaining battery capacity, the fourth is a table look-up series, a table of voltage, current, temperature and other input parameters, you can check the remaining battery capacity obtained.



So besides the batteries, the internal structure of the chip Battery Management there, the card contains a battery, or the two calculation methods for measuring the strength and clear cost benefits, and security. Of the portable system is through the use of this interface controller chip, and then adjust the battery cable.



So why the consumption of the battery for more than a small, but the implementation of the function of battery capacity correction can restore it? Laptop batteries are usually force the so-called 6-pin, 4 pin power, refers to the number of cells inside the Compaq HP 6710b battery cells. Batteries together soon, that is less capable of more significant reason to use: between the batteries and the quality of the batteries, discharge may be exactly the same level as the discharge, including the significant reduction in power, so to maintain voltage stability, the Board of the battery must be according to "bucket" theory, according to the worst charge batteries , power-saving protection, charged battery, of course, to reduce the irreversible even more than Chemical Physics battery change.



Function battery calibration is to balance the different batteries, the battery because it takes may not be exactly the same resistance to the battery is a great high current, causing more wear than other batteries, but also more wear and tear, then on a regular basis, it is necessary to perform an operation to calibrate the battery - it can balance the load of multi-cell " work ", so goes life in general.
