Tech Blog #07 | Fast charging !!
How many times have your Smartphone Ran Out of Juice while you are working?? How many days did you wake up With a Dead Battery?? I have plenty of such memories.. In situations like this, you want to charge your Smartphone As Fast as Possible, Right??
Charger is what cause the Charging Speed. Charging speed is measured as the power supplied by the Charger to the Battery to be Charged. It's measured by Watts (W). As for me, my Charger is 18W Fast Charger.
As a result, fast chargers were made. Pioneers of Fast Charging was The BBK Electronics. BBK Group consists of a few Smartphone Brands. They are Oppo, Vivo, Oneplus and Realme. So, they introduced their technologies through their Smartphones. Nowadays, all Smartphone Companies made their own Fast Chargers.
18W Fast Charger
Usually a 18W Charging Brick deliver 6V/3A or 9V/2A as it sums up for 18W.
30W Fast Charger
There are a few Generations of 30W Chargers since it was introduced. Current Generation is 50% more faster than the First Generation.
Nowadays almost all Smartphone Makers use Super Fast Chargers. Apple and Samsung are not in that Game. But other Manufacturers are deeply in it. Specially Smartphone Brands in BBK Group and Xiaomi. Most recent Flagship Smartphones of them Support 65W fast Charging and it usually charge a Battery 0% to 100% within 30 Minutes 😂. That's crazy fast. That's not it. Xiaomi and Vivo introduced 120W Fast Charging. The Charging Brick is a bit huge.
Fast Charging may decay the Battery faster. This will cause the vBattery Health. Fast Charging heats up the Battery faster. And Heat is not a Best friend of Batteries. When Delivering Higher Number of Amperes, the data cables also produce heat. It'll damage the internal Structure.
In order to achieve fast charging, architecture of the battery had to be changed. The Battery had to be Separated into a few Sections. Power was delivered separately.
To reduce heat, Coolant chambers were built under the Battery. To increase the Lifetime of Battery, they used Graphene, a Nano structure of Carbon. Cross Sectional Area was Increased in Data cables to reduce Heat which made in it.
Future of Fast Charging
I think Fast Charging came so far within last 2 Years. And that's really enough. What have to do is Improving those technologies without increasing the Number of Watts Delivered. Also, there is a Trending going on not to include Charger in the Retail Box.First, it was Apple. But now, other Manufacturers also doing it. So, the Hype Of Fast charging Is coming To a Dead End.
Nowadays Fast Charging is Essential for a Smartphone But Ultra Fast Charging is not needed. Surely it has Side effects whatever the technologies were introduced. 40W - 50W Fast Charging is enough for me. It can charge a 4500mah battery within less than Hour. But Let's see what's gonna happen in Future..
