A few days ago, the European Parliament and the EU council representatives reached an agreement. By 2024, the charging interface of all portable electronic equipment in the EU region was USB Type-C. In addition, the European Parliament Bulletin also pointed out that the charging speed of the equipment that supports fast charging must be unified, so that users can use any compatible charger to charge at the same speed. In China, the standardization of mobile phone fast charging technology is also being promoted.

As a tool that cannot be left, its endurance has become the primary criterion for consumers when purchasing. However, due to the size of the fuselage, the battery capacity cannot be increased infinitely. The focus of the manufacturer's battery life has changed from the battery to charging. From the five minutes of charging, it can "talk two hours" to "two hours of black", and the charging efficiency of mobile phones is getting higher and higher.

7.5W to 240W

Wired charging power grows geometric levels

Time returned to 2010, when USB IF officially released USB BC1.2, the maximum power charging reached 7.5W. In 2013, Qualcomm released the charging power of 10W, and was immediately popularized in 2014. Also in 2014, OPPO Find 7 released the 20W VOOC flash charging. The latter OPPO R7 series mobile phones also left the first impression of "charging five minutes, two hours of call" for consumers. At the beginning, mobile phone charging officially entered the era of fast charging.

Meizu released the 55W fast charge technology in 2017. Although it is amazing, unfortunately it has not been able to successfully commercial use. In 2018, the fast charging technology exceeded 50W, and the 65W fast charging appeared in 2019. At this year's MWC World Mobile Communications Conference, OPPO officially released the longevity version of 150W super flash charging technology. The fastest 15 minutes charge the mobile phone with an equivalent 4500mAh battery capacity to 100%. After a full loop of 1600 times, the battery can also have 80%capacity. OPPO not only pays attention to fast charging, but also focuses on safety, so that the life of mobile phone batteries has doubled industry standards.

On July 19, IQOO 10 Pro was officially released. The first commercial 200W ultra -pop -up charging, 10 minutes to fully charged, allowing fast charging technology to reach a new level. In addition, OPPO also released 240W super flash charging technology on 2022 MWC, claiming that it can be fully charged in 9 minutes. This is a new record for the current fast charging power of smartphones, which means that the charging time of smartphones in the future will be officially spanned across the way Enter a bit. Although this technology does not have practical demonstrations, it is still worth looking forward to.

Policy introductions high -power wireless fast charging is ended

Not satisfied with the "restraint" brought by traditional wired charging, the convenience of "not involved" wireless charging is also born. Of course, wireless fast charging has not been ignored.

Last year, when Xiaomi 11 Pro's magic version was released, it announced that it supported 120W wireless fast charging, but the largest wireless fast charging power on the market is only 50W. Why is it so big?

This is due to the fourth in Article 4 of the "Interim Provisions on the Management of Wireless Charging (Power Transmission) Equipment of Electricity) Equipment issued by the Ministry of Industry and Information Technology in February last year The power does not exceed 50W. The explanation given by the Ministry of Industry and Information Technology is that wireless charging will emit radio waves to the surrounding, avoid harmful interference to various radio services carried out in accordance with the law, maintain the order of air radio waves, and promote the healthy development of the radio industry. It is also worth noting that the radio or radio astronomy business is also noteworthy disabled in the disabled wireless charging equipment at the radio or radio astronomy business.

This "Regulations" has officially begun on January 1 this year, which means that high -power wireless fast charging has ended before it starts. However, most consumers interviewed that "believe in the regulations of the country and abide by national laws." It also made consumers feel that this is a new direction of R & D possibilities, and it depends on whether the future wireless charging will be better.

my country may take the lead in achieving unified charging standards in the fast charging field

Whether it is wired or wireless, the efficiency of fast charging has obviously become one of the important selling points of mobile phones. However, the fast chargers of different manufacturers on the market have specific private protocols and cannot provide fast charging services for other brands of mobile phones. This has also led to more and more chargers in the hands of consumers. Essence

In order to solve the problem of mutual compatibility of fast charging technology of various enterprises, the two standards of the "Mobile Terminal Convergence Fast Charging Technical Specifications" and "Mobile Terminal Convergence Fast Charging Test Methods" in early 2022 were introduced by the Ministry of Industry and Information Technology. Participate together to lay the foundation for subsequent research and development of relevant national standards.

In fact, it is not difficult to find that, compared to Apple mobile phones using the Lightning interface can only support a fast charge solution of about 20W-30W, the current Android mobile phone manufacturers have almost universal Type-C interfaces, which can support higher fast charge efficiency. You can give it to give it to it. Consumers provide a better experience.

In terms of fast charging technology, the advantages of Android mobile phone manufacturers, especially domestic mobile phone manufacturers, are still relatively obvious. They have invested a lot of manpower, material resources, and financial resources for research and development, and also achieved gratifying results.A variety of signs also show that in the future, my country may take the lead in achieving the unity of charging standards in the fast charging field. One fast charge can adapt to a variety of mobile phones, which will bring greater convenience to consumers' daily mobile phones.More environmentally friendly and more convenient, it is a good thing to benefit the people.
