FAST CHARGING IN MOBILES


                 Hey guys nowadays every smartphone comes with a fast charging feature. How fast charging works. Well let us see about this in this article.



Charging process of a battery:


                      Usually charging a battery is not a simple thing. As a normal people, they think that battery charges when we plug in the charger, but behind the scenes there is a process. A battery requires constant current when it is charging from 0% to 80%, but at the same time after 80% a battery needs constant voltage rather than constant current. These things are maintained and supervised by BMS (battery management system) . Normally, a 4000mah battery can able to charged fully within 4 hrs when the charger output current is 1A. But at the same time, it takes only 1 hr if the charger output is 4A. That the process where the fast charging works. But this type of increasing the charger current will make the battery overheated and may lead to explode. To solve this they use a high capacity electrodes inside the battery. Different companies uses different types of fast charging methods.



Is fast charging lead to overheating of device??

                 

                    Yes fast charging lead to overheating of the device but not so much of heating, a reasonable heating. This will not create any problem for the mobile. The manufacturer manages everything.

Is fast charging is safe????


        Answer is yes. Fast charging is safe. But it is safe till the time period where the manufacturing company or mobile company says. For example they say a 500 times of charging. Till that times of charging it wont create any problem. But after that the battery will begin to inflate and later it may explode. Thats why some companies uses a safety feature that if the mobile temperature is high the charging process will be stopped and it will continue after the mobile comes into the idle temperature.

                     Some company uses high voltage fast charging instead of high current. This is one of their fast charging method.
