What is the principle of TYPE-C fast charging connector?

Type-C is a USB interface connection interface, regardless of positive and negative can be inserted, the size of about 8.3mm x 2.5mm, and other interfaces like support for USB standard charging, data transmission, display output and other functions. type-c interface increases the current detection and current setting function, so that the USB side can detect the battery's power status for fast charging mode. A, USB3.1 type-c interface features: new interface design, size of about 8.4mm x 2.6mm, the interface is slim; power output capacity: standard cable 3A, interface 5A; available to transmit DisplayPort signals, support for 4K UHD image transmission: can provide a larger 100 of power transmission; better electromagnetic interference (EMI) and radio frequency interference (RFI) mitigation characteristics. RFI) mitigation characteristics; support for positive and negative insertion, can withstand 10,000 times repeated plugging and unplugging; USB Power Delivery, can support charging; higher data transfer speeds up to 10Gbps, based on the USB3.1 specification two, USB connector-type c interface charging fast for what reasons? Yuan Ai's USB-typec interface why charging fast, there are two main reasons, one is the far love of electronic research and development of the typec interface has four power lines, the power line thick allows the passage of the current is large, of course, charging fast; second, typec interface charging, allowing the charger to communicate with the cell phone's power management chip to increase the charging voltage, in the current remains unchanged, you can increase the charging power, the The speed is much faster, theoretically greater speed up to 100W. typec interface charging fast for two reasons, one, charging the charging line thick (multiple parallel), allowing a large amount of current; two, type c typec interface has a communication port, can be negotiated with the phone to increase the charging voltage, thereby increasing the charging power to speed up the charging (this is the super fast charging).
