Some time ago Apple, Dell, Sony, HP and other international well-known PC giants have emerged in the laptop battery problems and the recall of the original? Today I want to extend the subject to a number of laptop battery knowledge to share with you?
Why are books more you use the energy of the battery less? Why calibration function of the battery makes the ability to restore a game? How the correct battery charger? All this from the outset in the calculation of battery power … …
If she was eliminated in nickel-metal hydride batteries now used in lithium-ion battery, or not commonly lithium polymer batteries, or even tomorrow’s stars of the silver-zinc batteries are the equivalent of a warehouse Storage of electricity, the difference is that their approach to access the library, the storage capacity only. In the notebook computer batteries, and a great responsibility for the management of these batteries housekeeper - chips computing power, which is managing the battery, computing power, is responsible for loading and unloading of person “responsible”.
In the measurement of apple a1175 battery,apple a1185 battery technology, there are four types of common method, but not books of different brands of batteries using a single method for calculating the energy consumption are usually several ways to use an integrated approach in one of the main method of calculation The calculation remaining auxiliary means to achieve the computing power to manage. The first is the open circuit voltage measurement method, this method is to measure the battery voltage in the steady state values to calculate the remaining capacity of the battery, but because of stationary lithium-battery voltage and ion the remaining capacity of the relationship between non-linear, therefore, this method is not an accurate measure of the value of the vast majority of cell phone batteries have adopted this method of calculation, the second method is called Coulomb calculation, the method is to measure the battery charge and discharge current, the current value and time value of After the product is calculated by integrating the batteries into the battery charge and discharge electricity The Coulomb method of calculation is a more precise method of calculating power, the third is the method of impedance measurement, it is by measuring the resistance within the battery to obtain the remaining battery capacity value, the fourth is a complete look-up table methods, setting a linked table, voltage, current, temperature and other inputs, you can check the remaining capacity of the battery to be.
Thus, apart from the internal structure of cells of the battery, there are management chips, the chip contains one or two of them measuring method for calculating the battery capacity, and a whole load and the circuit protection against discharge. Among the notebooks in the system, through the driver interface access to this chip, then set the power management.
So why the battery would be more you consume less electricity, but the implementation of the correction function can restore the apple m8403 battery,apple ibook g4 12-inch series battery capacity of a part of it? Laptop batteries are usually the so-called six-pin power, 4-pin power refers to the number of battery cells in batteries. Both batteries at the same time, the less electricity you use the most basic reasons: batteries and battery between the quality of the discharge may not be exactly the same level as the discharge, in which a substantial reduction battery power to maintain stability of the voltage, the chip Battery Management will follow “barrels principle”, as the worst economy this basic energy for load protection, battery will be a natural decline, the impact is even greater than the battery irreversible Institute of Chemical Physics change.
Calibration function of the battery is to balance the multiple batteries, the battery because of their resistance can not be completely consistent, the battery will therefore resist mainstream box, leading to their own consumption more than other batteries, but also easier to wear and tear, therefore, on a regular basis to calibrate the apple laptop battery ,hp laptop battery is required - to balance the load of multi-cell “work” and increase hope overall life.
