Laptop battery is used, the less the more normal? To explain this, you have to talk about the structure of the battery itself. Before we understand the basic structure of the battery, notebook batteries and battery is composed of management chip. Batteries that store electricity "warehouse", power management chip is able to calculate and manage the charging and discharging process. The main element in the functioning of batteries is lithium, which is a dynamic element, in order to protect the security, can only exist as ions in the battery. Lithium batteries similar shape with ordinary batteries, laptop batteries, but do often occur in groups. We often see the "four core", "six-core" refers to the battery in the battery is the number of batteries.
Batteries and more, means that capacity is large, the number of high-capacity batteries battery is generally about eight. The reason comes to batteries group, because a group of batteries is the battery charge decrease the "culprit." Batteries batteries each group, its quality and discharge levels vary. After discharge, in order to maintain voltage stability, management chip detects that a worst batteries charging protection. Often the past, the entire battery power naturally will gradually decrease. This phenomenon can be used after the battery calibration function, this function can be balanced multi-cell battery burden "work."
It should be mentioned here have battery power measurement methods, common approach four kinds, but in general are integrated several methods used in one of the main methods for calculating manner calculated to achieve the remaining auxiliary power calculation and management.
Open circuit voltage measurement
This method is by measuring the battery voltage value in the stationary state to calculate the remaining capacity of the battery, but because the relationship between lithium ion battery voltage and remaining capacity of the still between the non-linear, and therefore the measured value of this method is not accurate the vast majority of cell phone batteries have adopted this method of calculation.
Coulomb calculation
This method is by measuring the battery charge and discharge current, the product of the current value and time value are calculated by integrating the battery after the charge into the charge and the release of electricity, Coulomb calculation method is a more accurate power calculation.
Impedance measurement
It obtain residual capacity value of the battery by measuring the internal resistance of the battery.
Comprehensive look-up table
By setting a related table, voltage, current, temperature and other parameters input, you can check to get the battery's remaining capacity.
But no matter which method, while charging management chip follow the "bucket principle" to the status of the worst batteries subject to protection. Therefore regular correction can protect the battery cells to some extent, to extend the overall life of the battery.
