Understanding Different Charging Protocols
By Anan Sadh – There are many different types of fast charging protocols such as OPPO’s open VOOC Flash Charge, OnePlus WARP / Dash , Realme DART charge, Qualcomm’s Quick Charge fast charging & PPS / PD Fast Charging. Some of these are proprietory ( Flash, Dash, Warp, Dart, VooC) & QC,while some are open platforms ( PD & PPS) Nowadays, smart phones have quick charging between 18W to 65W power, with charge times going from 30 minutes to a little more than 60 minutes. Let’s broadly understand the differences. Qualcomm’s Quick Charge QC3.0 / 4.0 Qualcomm’s QC Quick Charge is very familiar today & it is a representative of a high-voltage fast car charger . It was first launched in 2013 when the highest power was 10W (5V/2A). By QC 3.0, the power increased to 36W, & now it supports 200mV step voltage regulation, which is no longer a fixed set of voltage & current. QC 4 supports s...
