Mobile phone flash charging patent

A few days ago, OPPO officially released the 240W super flash charging technology at the 2022 MWC Mobile World Congress (MWC 2022). This technology can quickly charge a battery equivalent to 4500mAh to 100% in less than10 minute, and refresh the charging efficiency of smart phones again, becoming the fastest charging technology in the mobile phone industry.

According to statistics, 240W is the highest wired fast charging power announced by all smartphone manufacturers at present, and according to OPPO official laboratory data, 240W super flash charging technology can support 24V/ 10A charging at the highest, which can quickly fill a battery equivalent to 4500mAh in 9 minutes at an unprecedented speed. At the same time, the technology is also compatible with mainstream charging protocols such as PD and PPS, which truly realizes multiple charging of one device, regardless of brand and model.

In addition, in terms of temperature control and heat dissipation, 240W super flash charging technology can ensure the temperature control and safety of the adapter, wire and battery during the whole charging process, greatly reduce the heat generation, and realize the whole process of "cool" flash charging, which is not only safe but also efficient.

OPPO can constantly break through the speed limit of refresh flash charging, relying entirely on its proud VOOC flash charging technology.

OPPO has been leading the development of fast charging technology since 20 14 introduced VOOC flash charging technology. At present, more than 30 products equipped with VOOC and SUPERVOOC technologies have been launched, allowing more than 220 million users around the world to experience the charm of OPPO flash charging.

The 240W super flash charging technology exhibited this time is the further design optimization of 150W super flash charging by OPPO SUPERVOOC team, and the charging protocol is added, thus realizing the 240W super flash charging.

In fact, OPPO has been deeply involved in the field of fast charging for many years and has already established its own technical advantages. According to the data, by the end of 20021,the global patent application volume of OPPO in the field of fast charging has exceeded 3,990, of which about 1786 have been granted, and the patent authorization for flash charging is open to more than 50 enterprises.

At MWC 2022, in addition to 240W super flash charging technology, OPPO also released a long-life version of 150W super flash charging technology, which can double the battery life of mobile phones. The long-life version 150W super flash charging technology follows the OPPO charge pump direct charging technology, and the mobile phone with the same battery capacity of 4500mAh can charge from 1% to 50% in 5 minutes, with the fastest charging speed of 65430. And equipped with the battery health engine independently developed by OPPO, after the mobile phone is charged and discharged 1600 times, the battery can still have 80% capacity, which makes the battery life reach twice the industry standard and effectively protects the battery health.

According to the official announcement, OPPO's 150W super flash charging technology will be commercialized in the second quarter of 2022, and will be launched on its one plus mobile phone. 240W super flash charging technology is still in the laboratory stage, and it does not have mass production conditions for the time being. It is estimated that the fastest commercial time will wait until at least the end of this year or next year.
