USBPD increases power transmission through USB cable and connector, which expands the power supply capacity of cable bus in USB application. This specification can realize higher voltage and current, the maximum transmission power can reach100W, and the power transmission direction can be changed freely. However, it can't be said that USBType-C interface will definitely support USBpd protocol fast charging, and the biggest advantage of pd charging port pair is its support for double-sided insertion.
USB-PD protocol is a universal standard introduced by USB-IF association of America to meet the needs of modern fast charging. This standard covers previous proprietary protocols such as Qualcomm, MTK and Huawei. , and at the same time subject to supervision. Industry giants such as Google and Apple are accelerating their support for this standard, and this agreement has been recognized by Tell Laboratories of China's Ministry of Industry and Information Technology.
? Characteristics of fast charging of partial discharge
1, supports double-sided insertion.
2. In addition, PD fast charging and fast charging protocols can also run higher charging power.
3.USB-PowerDelivery is one of the mainstream fast charging protocols, and it is a fast charging specification formulated by USB-IF organization.
4.USBPD increases power transmission through USB cable and connector, which expands the power supply capacity of cable bus in USB application.
5. This specification can realize higher voltage and current, the maximum power transmission can reach100W, and the power transmission direction can be changed freely.
