Controlling the circuit plays a key role in the actual performance of the NV52 gateway laptop battery, because that will help establish and maintain a good balance of the internal performance of the battery. Not only must the charging and release of the electricity of the battery be controlled, for example, beginning to and ceasing to charge the battery in the proper time, by controlling the electric current of the charging and release of electricity in a suitable range, but users must undertake the analytical records of the situations of this battery (for example, our familiarity with the exhibition of the capacity of this battery as well as with the recording function of the times of charging and release of electricity). Users should also undertake the protection of this NV52 gateway laptop battery by cutting off the circuit when the temperature of this battery is too high or when the electric current is too strong.
This NV52 gateway laptop battery is characterized by a control circuit which, situated between cells and the mainboard of the laptop computer, is a very complicated circuit according to the working principles and design. This control circuit has two parts. One part serves to protect the battery in the course of its being charged and its electricity being released; the other part, otherwise referred to as the Gas Gauge, serves to provide a scientific management for the communication of the battery group with the main machine and for the application of the battery. Generally speaking, the two parts are both designed on a circuit board. In case the NV52 gateway laptop battery adopts a Li-ion battery, then there will be a circuit that has two parts; in the event of the battery's adoption of a Ni-MH battery, then there will be a Gas Gauge only, because only a Li-ion battery carries a protection circuit, while a Ni-MH battery doesn't.
