With the advent of the intelligent era, the function of electronic devices such as large-screen mobile phones, laptops, and tablet computers have become increasingly abundant and intelligent. However, at the same time, it has brought the problem of a sharp rise in power consumption. In the case of no breakthrough progress in existing lithium battery technology, people have begun to explore more “electricity replenishment” in the field of fast charging. The fast charging formula is: energy (W) = time (T) × power (P). To increase the charging speed, the key is to increase the charging power. Therefore, USBPowerDelivery (USB_PD) was born as the most mainstream fast charging technology today.
