September 17 The VOOC flash charging technology conference is said to be the longest OPPO conference ever.

OPPO’s original expectation is that the SuperVOOC 2.0 with 65W charging power can fill a 4000mAh battery phone in half an hour, and the conference will end in about half an hour. Then the charging demonstration and the conference will start at the same time. This has a very dramatic “program effect.”

In fact, this dramatic effect did not happen. The number of Keynote pages used in this conference is not too large, but Zhang Jialiang, who has been concentrating on the development of VOOC flash charging technology for 7 years, is very familiar with the technology developed by him. There are three openings in the VOOC family. The new technology is enough to talk about 2 hours, which is enough to fill the 4000mAh battery 4 times.

The industry already has a general solution, why should he do VOOC

After the conference, Ai Faner interviewed Zhang Jialiang, the person in charge of the VOOC flashing team, who is known as the “Father of Flash”.

Zhang Jialiang, who entered OPPO in 2004, has been working in this company for 15 years. It happens that the VOOC flash charging technology conference on September 17 is also OPPO 15Birthday.

As an employee of the same age and OPPO brand, Zhang Jialiang’s position within OPPO is actually quite rare: R&D scientists. Within the entire OPPO, there are only four employees with the title “Scientist”.

It is curious that Zhang Jialiang has to do VOOC flash charging research and development in the industry.

Yes, the development of VOOC flash charging was actually Zhang Jialiang’s amateur research project, not the OPPO officially established research and development project. In the era when 5V1A is the mainstream and 10W charging is considered to be higher power, the charging speed has become an experience pain point for Zhang Jialiang himself in the use of electronic products. He is just an electronic product enthusiast. Until now, it is still a middle-aged person. In the end, he was a “geek” who was technically and knowledgeable to solve problems.

The three conditions are superimposed, and there are interest points and abilities, which constitute the motivation for Zhang Jialiang to embark on the VOOC flash charging research and development journey.

In the “15-year-old OPPO, 15 stories” of OPPO official public number OPPODAILY, recordSuch a story:

In 2012, OPPO was not well-developed in the smartphone market. On the tail of the Spring Festival, several engineers used the materials in their hands to stack a thin and smart smartphone Demo with a thickness of less than 7 mm. Taking advantage of the wine, they took the prototype to Tony, and Tony fell in love at first sight and immediately made the machine the key model in 2012. This is the Finder that shocked the industry.

The path of VOOC flash charging started in the same year is similar. When Zhang Jialiang started to develop this technology, OPPO was deeply affected by the transformation, and the laboratory resources and tool resources were far less than today. Zhang Jialiang and the other three partners who did the research even bought a lot of experimental equipment from their own pockets, including hundreds of infrared thermometers, tens of thousands of multimeters, and even nearly 200,000 digital oscilloscopes. These devices are hidden in Zhang Jialiang’s dormitory, which forms the laboratory in the dormitory.

Google and Apple, which originated in the garage, and Facebook, which also originated in the dormitory, prove that talent is a more important factor in entrepreneurial creation than the environment.

Zhang Jialiang said:

The company has also done professional evaluations for me. I don’t necessarily recognize other items, but I am more convinced. It shows that my ability to resist pressure and resist is relatively strong. I myself brag about it with my friends around me. I said that I was covered in the sky and covered by a quilt. I also think that if a person’s ability to resist setbacks and fight against blows is not enough, it is difficult to do things, and it is so easy to do things.

The reason why he wants to emphasize his ability to withstand pressure is because even if he can overcome the difficulties of the laboratory and equipment, VOOC flash charging technology from his dormitory to the real machine business, there are thousands of miles.

VOOC flashing first in the Find 7 phone, there are also a lot of doubts inside, the two logics are the most common:

• What Apple and Samsung don’t do, why do we do it?
• Qualcomm and MTK have ready-made solutions that are compatible with the same use. Why do we do it ourselves?

Today OPPO has proven that their low-voltage, high-current solutions are superior to earlier high-voltage fast-charge solutions in terms of efficiency, safety, and heat generation. However, around 2013, Zhang Jialiang’s work is from 0 to 1, not only to re-do the custom charging head and charging line, but also to the company’s management and the quality department with one vote veto “over the review.”

This means that as the project leader, Zhang Jialiang will also persuade the supplier to cooperate with the plan to produce materials while carrying out the research and development of the team. It is necessary to prove the feasibility of the plan to the company management and the quality department. This is not a smooth process. Compared with research and development capabilities, Zhang Jialiang’s communication skills are not outstanding enough.

In retrospect, Zhang Jialiang was very pessimistic about the situation:

In fact, it is a good explanation for yourself (the reason for doing VOOC research and development), that is, the support of hobbies, and it is said that love is tossing.

In fact, the company explained that it was not anxious to let the company recognize VOOC flashing. Moreover, if you work hard enough, the company will definitely recognize it, otherwise it will not spend so. Long time.

At the time, I could understand that VOOC flashed such a new thing. If I put it on an important product, I am the boss. I will also consider how to break this issue. It really means that you have not done enough well. If you don’t work hard enough, you will continue to toss. If you can’t say it, you can’t do it. You can’t do it yourself.

Batteries are also standard, the biggest standard is consumers

Today, VOOC flash has more than 145 million users, and Zhang Jialiang has passed the stage of demonstrating the value of VOOC flash to the company.

However, there is a group whose veto power is greater than the company management and quality department. Zhang Jialiang said:

Batteries are also standard, including national standards and standards. Each company has its own enterprise standard, but the ultimate standard is consumers.

In fact, at the time of the interview, the two most mentioned words by Zhang Jialiang were “user value” and “balance.”

At the beginning, Zhang Jialiang’s experience as a user’s pain point was the cause of VOOC’s birth. To the back, the needs of tens of millions of users are the driving force behind the evolution of VOOC flash charging technology.

The VOOC flash charging technology is really popular in the north and south of the country. It is the advertisement of “5 minutes of charging, 2 hours of conversation”, and the R series mobile phone is selling well, but in fact, VOOC flash charging technology is not perfect, such as The charging head and charging cable are custom made, the charging head is bigger and heavier, and the line is thicker.

Zhang Jialiang makes an analogy to this trade-off:

It may not be appropriate to give an example, but this is the real experience I have encountered.A buddy went to buy a digital camera, and the salesman had a problem with his ideas. He told him how to save power. Does the consumer recognize it? What I want is good or bad. Can I make a good photo? How can I tell him that saving electricity is useless?

This is Zhang Jialiang’s “user value” and “balance”: in the face of faster charging speed, consumers can accept larger charging heads and thicker charging lines.

He further explained:

There are two roadmaps inside OPPO. One is the technical road map, the other is the product road map, and the technical road map is “building arms”, which is to enrich the technical shelves. The product roadmap is to control the release of the product and the rhythm of the product. The two road maps are insulated from each other. It doesn’t mean that you have something to use. It doesn’t mean that it has anything to do with what you have.

The recent OPPO’s 65W SuperVOOC 2.0 and 30W wireless VOOC charging technology are all ready on the technology shelf.

When is the balance of the “arms” in the “Arsenal”? Zhang Jialiang said:

There are many things to balance on the product side, such as market trends, consumer appeals and habits, including a series of factors in the competitive market.

So, from the outside world, the previous 50W SuperVOOC super flashing, the 65W SuperVOOC 2.0 has been leading the commercial market, but when I asked, “Is there a little bit in front of my own leading results? Zhang Jialiang’s answer was a bit unexpected when he was satisfied or proud?

This has not been considered, pride can not be talked about, satisfaction can not talk, said negative can not talk, I think these are logical.

30W wireless VOOC flash charging technology is the first wireless charging technology released by OPPO (the previous Finder can be wirelessly charged by adding a back clip). Before that, there were countless models of wireless charging mobile phones in the industry. Palm Pixi Plus and Lumia 900 in the early days of smart phones, Samsung Apple and so on.

Why did OPPO release wireless charging technology until now, and is it the industry-leading 30W power?

Zhang Jialiang said:

In fact, OPPO’s first generation of wireless charging is done from 5W charging power, and other versions must have been tried in the middle, but for the sake of value or competitiveness, this is released, but it does not mean OPPO. The inside only drummed this one. We also have bigger ones, but they are not released, and of course there is less power.

The release is now closer to the market demand. Now, there is definitely no value in getting a 5W charging power. If the whole one is higher, other factors may not be worthwhile.

(5W and 10W wireless charging) is really worth the user
