Now the fast charging market is developing rapidly, and fast charging has become a rigid demand for people's lives. For example, our mobile phones, computers, tablets and other electronic devices need to use TYPE-C fast charging for charging, data transmission and display output.
At the same time, fast charging has been developing in the direction of higher power, and the standard of fast charging is constantly being updated. On May 25, the USB-IF Association updated the v2.1 version of the TYPE-C fast charging cable and interface standard.
In the TYPE-C fast charging specification, the power is increased from 100W to 240W. Specifically, this 240WPD USB Type-C extended power supply is mainly to increase the voltage, from the previous 20V5A to 48V5A, rather than a high-current solution. For the cable will still support 5A current. There is some compatibility with current cables.
In fact, the USB PD fast charging standard has experienced 10 years of development and has been widely used in consumer power products, but most of them are limited to consumer electronic products such as smartphones, tablets or laptops.
There are many fast charging protocol standards in the market, such as Qualcomm QuickCharge solution, MediaTek PumpExpress and OPPOVOOC solution, among which USBPD is gradually becoming the fast charging protocol standard, USBPD charging is compatible with different voltages of 5V\/12V\/20V and different currents of 1.5A\/2A\/3A\/5A It can support up to 100W of power. According to Jeff Ravencraft, chairman of the USB-IF, in the future, it will cooperate with the International Electrotechnical Commission (IEC) to unify the standard charging interface, so that all devices can be charged with a maximum output power of 100W through USB Type-C. Safety mechanism design It will be carried out on the board. If the connecting wire does not meet the certification specifications, it will automatically switch to the lowest standard voltage power supply mode to prevent the wire from being burned due to the unbearable voltage. The combination of Type-C and fast charging is not only for the fast charging protocol standard The formulation brings new opportunities and also makes the market prospect of Type-C broader.
