Li-ion/ Li-Polymer Battery Charging:
Li-ion or Li-polymer batteries are charged in two phases.
1) constant Current phase
Li-ion battery is charged with constant current and the voltage across Li-ion battery increases gradually. The battery gets its 60-70 % charge in the first phase itself.
2) Constant Voltage Phase
Once the Li-ion battery voltage reaches the desired charge voltage, the voltage across the battery is maintained constant and the battery current is gradually reduced until it reaches the charge termination current.
(*Charge termination current and maximum charging voltage is decided by manufacturers )
Fast charging:
For fast charging the Li-ion/ Li-polymer batteries, they are charged with the higher battery current in the first constant current phase of charging.
Broadly, in fast charging technology, the smartphone is fast charged either by charging the battery at the higher voltage (9V/2A) or at higher current (5V/ 6A).
In this video, Qualcomm's Quick Charge technology, fast charging with USB-PD, and Oppo's Super VOOC technology are explained.
This video will be helpful to everyone in understanding how fast charging works in the smartphone.

Very good explanation
Yes sir, I want to know about gallium nitride please please 🙏
So I can charge my tws with infinity watt fast charger which gives 5v initially.
thanks for easy explanation.
Superb 😊🔋🔌
Jabardast video
Sir can you provide us major course of power engineering ?
I need it
Nicely done
Awesome video dude, you deserve more views... I have one question... I have oneplus 8T, and has the 65W technology you mentioned in the video... The 10V are divided by 2 between both batteries. If u charge my smartphone with 5V/2A charger, how the system works? Charges one battery and then the other one ?
I am not sure whether it will charge with 5V/2A charger. As per company, apart from 65 W charger, it supports USB-PD upto 27W.
Sir always explain from basic to the higher level ❣️❣️
Do u conduct any online Webinars??
Make a video regarding gallium nitride also.
explain about
Gallium nitrade
Want to know more about USB power delivery and gallium nitrade based charging...
thanks

I want to know about gallium nitrate
Which lithium battery type is best for long range and long battery life? NMC(INR chemistry, eg: Samsung INR 35E) or NCA(NCR chemistry, eg: Panasonic NCR 18650B). I'm a teen DIY enthusiast and have immense taste for electronics but I have no idea about such electro-chemistry. I read long articles claiming the Panasonic battery is also used by tesla and its cycle life would increase if the battery is kept between 70%-30% charge. Is this thing true for all lithium ion battery or is it only for the Panasonic, because other than a good capacity battery I also want long life. On the other hand, Samsung is base on NMC technology which is recommended for Powerwalls and due to their high discharge capacity people also use it for DIY batteries.
Please help me out, I'm searching for an answer from a long time. Its a humble request please reply.
Although whatever I said was not related to smartphones but EV's to be exact.
Yes got an ideal ieda
Ma fav channel
At 13:38 you mentioned that , in the lastest 125 Watt charging they are supplying 20v 6.25A of current , now the charge pumps are inside the phone right and then they convert that 20v to 10v 12.5A then how can you say that most of the circuit is outside the phone , wherein the actual increment in the charging current is happening inside the phone itself , which should make the phone hot . And if you say that the current is being increased by the charger then at the end of the day how the cable is able to carry that high of a current .
Does candytech make real flash charger or fake
I would like to know more, specifically about the simple things, their purpose and their usage. This was Informative but
not well organized. It's lacking some... concepts, or meaning of other things. BUT I will search about it anyways. goof vid
Sir, can u make a video on battery electrical vehicle.
Yes, some day will also make the video on it.
sir in case of USB 2.0 if the signal pins are shorted to increase the current but in return path means in ground still have same wire so how ground wire withstand on that current level??
Data is transmitted on D+ and D- using differential signaling. Power is provided through Vbus and ground. In DCP port (USB BC 1.2), D+ and D- are shorted. They are separate from ground pin. (Because as I said, data is transmitted using differential signaling)
I hope it will clear your doubt.
5:05 Why do they produce more wattage when shorted together? (I am not good at electronics). Good video!
It's USB standard. USB BC 1.2. As per the defined standard it provides more current.
@@ALLABOUTELECTRONICS Oh i see. Thanks!
My 1st visit to ur channel sir...i am impressed..as a viewer i should suggest u that u should open a hindi channel also...it will be more venificial for u sir..so that hindi audience will attract to ur channel 😁😁😁

Good Explanation so tell me Cons of Fastcharging?
You might have heard that it affects the battery life in longer run. But not really. It can affect the battery life at some extent but there are many other factors which may degrade the battery life. Like temperature and the charging voltage ( full charging voltage).
But day by day, because of improvement in battery management system, it can be taken care.
On an average modern smartphone batteries last 400-500 charging cycles ( 0 to 100% charging and discharging) before battery capacity reduces to 80%.
That's typically 1.5 to 2 years for average user.
And with fast charging when batteries can be charged in 15-20 mins ( 50-60%), it's not major issue.
@@ALLABOUTELECTRONICS ok Bro Thanks for giving Useful information. Keep Rocking ❤️🤙

Sir, what is the advantage of having 2 cells in series ?
More than 5V can be applied between the two series cells (e.g 10V/ 6.5A) without down conversion of the voltage .
sir , is fast charging depends on fast processeser
It depends on the Processor. It has nothing to do with the speed of the processor. If you see an older processor, they won't support Q.Charge 4.0. But the new ones at least support Q.C 3.0 or USB-PD.
Some companies use their propriety technology with the same processor.
The thing is, although processors support some fast charging tech provided by chipmakers, OEM needs to enable that fast charging chip inside it by paying extra money to chipmaker (Qualcomm or Mediatek). Otherwise, even after using the same processor, one may not get the fast charging.
I hope it will help you.
Thanls sir
Current technology is limited by the lithium ion battery. Once we break the barrier, electronics are gonna evolve.
So by increasing the voltage, current can be pushed into the battery faster? Does the voltage decrease as the battery starts to get full?
As I mentioned, there are two phases of charging. In constant current mode, the battery is charged by constant current by the charger IC. During this time, the voltage across the battery gradually increases. Once the battery voltage reaches, some predetermined voltage level (near the maximum charging voltage of the battery), the charging IC switches to constant voltage mode, where it tries to maintain the voltage across the battery and current reduces.
I hope it will clear your doubt.
ALL ABOUT ELECTRONICS Yes but when fast charging does it start with a higher voltage for example 10v to get it charging faster?
You mean bus voltage through charger? Yes, it starts with high voltage. But inside the Smartphone, it is down converted through charging IC.

What is the difference in fast charging and flash charging???
It's just a same thing with different marketing name.

The graph made me not stay to the end of the video the make it look so difficult to understand
Why the phone getting heat while charging
The one reason is while charging, some of the power will get dissipated in the form of heat. But now a days, most of the phones and the charging IC keep the temperature under check.
While charging, if phone is being used then it may increase the phone temperature. Or perhaps if some background activities are going on then it may also cause the heating problem.
