Principle: VOOC flash charging is a very intelligent and safe charging technology. During the charging process, the battery temperature, battery charge, interface contact and communication between the adapter and the mobile phone will be monitored in real time, and the charging current will be automatically adjusted according to the above factors during the whole charging process. VOOC flash charging is a fast charging technology independently developed by OPPO. It has applied for 18 patents, which has increased the fastest charging speed by more than 4 times, and has impeccable intelligent full terminal five-level protection. It is the fastest and safest mobile phone charging technology in the world.
First, flash charging
1, interpretation:
Flash charging is a fast charging technology, which can make the mobile phone fully charged in a short time. Independent research and development by OPPO, applying for 18 patent, the fastest charging speed is increased by more than 4 times, and it has impeccable intelligent full-terminal five-level protection.
2, technical principle:
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.
3, technical application:
20 16 February 23rd, Barcelona, Spain, OPPO demonstrated its latest black technology at the 20 16 World Mobile Communications Conference (MWC20 16), mainly including the latest achievements of fast charging and imaging technology-OPPO VOOC super flash charging and SmartSensor image chip anti-shake technology, and OPPO VOOC super flash charging 65438.
4. Use comparison:
OPPOVOOC flash charging 5V5A charging for five minutes and two hours, 30 minutes and 75%. (Data are based on laboratory test results in specific situations. The actual charging effect is influenced or different due to battery capacity, temperature and other factors, and the actual talk time is different due to the different use state and environment of the mobile phone. )
5. Technical background:
Battery life has now become one of the biggest bottlenecks limiting the development of smart phones. With the increasing size of mobile phones, many manufacturers also choose batteries with larger size and capacity to improve battery life. But it also means that if we want to ensure the same charging time as small-capacity batteries, then large-capacity batteries need to support faster charging technology, and flash charging is one of the effective methods to solve this problem.
