Fast charging is a fast charging technology that can make the mobile phone fully charged in a short time. Independent research and development by OPPO, applying for 18 patents, the fastest charging speed is increased by more than 4 times, and it has intelligent full-terminal five-level protection. It is the fastest and safest mobile phone charging technology at present.
According to the mode of low voltage and high current, flash charging technology can shorten charging time by increasing voltage or current under the premise of constant power. ?
Flash charging is to increase the current by using the mode of low voltage and high current. MCU is added to the charger power supply and battery circuit respectively to replace the step-down circuit. On the premise of low voltage and high current, the output of sectional cross-flow current is realized by opening the voltage loop.
