What is the Prospect of PD3.1 Super Fast Charging Protocol?
On May 25, 2021, the USB-IF Association launched USB PD3.1 super fast charging protocol, specifying the maximum output power remained unchanged at 100W and, at the same time, adding Extended Power Range (EPR for short) which extends maximum out power from 100W to 240W.
EPR adds three new fixed voltage ranges of 28V, 36V and 48V and three adjustable voltage ranges (Adjustable Voltage Supply, AVS for short); maximum current level remains unchanged at 5A.
Apple also launches the corresponding PD3.1 notebook computer in 2021. From this point of view, the high-power fast charging of PD3.1 will be popularized to most digital terminals. Apple has been promoting the application of the USB-IF industry standard in terminals, and with its strong brand influence, it has moved almost all of its product lines to USB-C applications.
We believe that in measurable future PD3.1 will be compatible with more and more devices in the terminal. The home appliances closely related to us will enable corresponding PD3.1 charging protocol soon. The products already built in with this super fast charging protocol include MacBook Pro 2021/2022, smart home appliances related products etc..
Going forward, PD3.1 will become a common fast charging scene of daily life, which can be used at will in products such as low-power electric vehicles (2 wheels), desktop computers/power tools, etc., so the world will be truly interconnected.
