How to measure the power consumption of notebook battery The original article posted in http: //www. laptops-battery. co. uk/blog/ Why laptop battery pack capacity reduce as effort? Why battery calibration could improv battery capacity? How you can charge the battery appropriately? All above probelm are associated with battery power consumption. Open up circuit voltage measurement...... Coulomb dimension, impedance measurement, what are generally these terms mean? Here we will simply introduce them all! Whether it is any out nickel-metal hydride power packs, lithium-ion Dell laptop battery, or not commonly applied lithium polymer batteries, as well as coming silver zinc batteries, are equivalent to that a storage warehouse regarding electronic power. The differences between individuals is that the way from the Treasury, the volume involving stocks it. In laptop batteries, there is a power manage center - strength consumption chip, it will be the management of power measuring just, charging and discharging handling. In the measurement involving battery technology, there are generally four kinds common tactic (open-circuit voltage measurement, Coulomb calculation, impedance measurement, integrated look-up table method), but not all batteries used merely one method, usually using a mixture off methods to one of many method of supporting the rest of the way computing power. The very first one is the clear circuit voltage measurement, this process is that measuring that battery voltage under static values to calculate the remaining battery capacity, but due to stationary lithium-ion battery voltage along with remaining capacity relation can be non-linear, so this process measured valueis not complete, the vast majority of cellular telephone batteries are calculated that way; <! --INFOLINKS_OFF-->

The 2nd one is Coulomb computation, the method is by simply measuring the laptop battery pack charge and discharge current, the current value and time value After the calculation of product integration have been carried out by filling the battery in the power and the let go of electricity, Coulomb's method is really a accurate method of keeping track of power; The third one is the impedance measurement, measuring its resistance to find the remaining battery capacity valuation; the fourth is a comprehensive look-up table method, by establishing a related form, the actual voltage, current, temperature along with other parameters, you can query the remaining battery capacity. Therefore, as well as the internal structure of that battery batteries, there are generally control chips, the chip which contains 1-2 types of batteries power measurement method of calculation, and a charge-discharge protection circuit. battery manage program have been setted in the technique, and through access to the chip-driven interface, and then set on the battery management. So, why the battery will end up weak, but the battery calibration can improve the battery capacity? Notebook battery 6-cell and 4-cell, means that there are numerous of battery cells inside battery. The batteries cellular material conenect together, the battery capacity reduce reason is without a doubt that: all the batteries superior and discharge rate can not be in the same place. After discharge, one battery cell capacity in huge reduction, in order to take care of voltage stability, the battery management chip is going to be according protection of core power as the "bucket principle", so following the electricity charge will decline. Battery calibration is to balance the multiple battery pack cells, the cells own internal resistance can not be completely consistent, the large internal weight battery will shoulder the larger current, and its own consumption over the other batteries. So regular battery calibration is essential - it can balance the responsibility of multiple batteries work and prolong the whole battery life. <! --INFOLINKS_OFF-->.
