Battery - one of the main pieces of equipment and stand-alone backup power. Often the battery does not fulfill its resources and its accounts ahead of time replaced by a new one.
Cell battery - low-voltage device, so they are usually connected in series in the stack. Ideally, if the parameters of all the batteries are equal, we have a source voltage to the n-times larger than a single cell, and the charge-discharge it we can more as a single high-voltage battery.
But it is only an ideal. Each battery pack in this unique and different characteristics of the cells lead to the fact that the batteries operate in different ways and, as a result of the total composite capacitance of battery will be lower than its constituent cells, it is time, and secondly, a resource such as the battery will be lower, because it is determined by the "weak" battery that will wear out faster than others.
In the sequential method of charging the battery is to fulfill one of the main requirements: the voltage on any section of the rechargeable battery for charging should not exceed a certain value. Do not take special measures to ensure compliance with this requirement consistent with the charge - is unreal.
There is a situation when we have to stop charging, as the voltage on one section has already reached the maximum threshold. At the same time, the other sections remain nedozaryazhennymi.
To prevent overvoltage during charging, above a certain threshold, and is balancer . Its mission is: to monitor the voltage of the battery in a separate section. Once the voltage on it when charging reaches a certain value, balancer gives the command to switch the power key, which is connected in parallel with a rechargeable section ballast. At the same time charging the remaining sections, the tension which has not yet reached the maximum permissible values - will continue. Ends the charge process that will work Balancers of all sections of the battery. The voltage on all sections will be the same, and equal to the threshold, which set up Balancers .
The company has GreenChip offers you to buy Balancers for different types of batteries!
