Chapter 1142: Power Bank

Feng Yu approached Fu's family to help with Aihua Xiaobawang's listing in Xiangjiang. At this time, another piece of good news appeared.

Taihua Battery Company has finally completed one of Feng Yu's plans, which is to produce mobile power supplies. This was just a concept before, and many companies claimed to have researched it, but none of them launched a product.

It is rumored that the world's first small mobile power supply was invented by an overseas student in the United States. It uses a few dry batteries and converts it into a current that can charge mobile phones through a small circuit device. The place where it first appeared was the Consumer Electronics Show in the United States.

But now, the exhibition has not yet opened, and it is estimated that the mobile power supply has not yet been finished. Although Sunny claims to launch a mobile power bank soon, this statement has been mentioned for several months, isn't it still not believed at all?

The chief engineer of Taihua Battery Company brought the samples to Fengyu Building in Beijing, and showed Feng Yu the mobile power supply in Feng Yu's office.

"Please see, we use a high-energy lithium battery, which is designed in a columnar shape. The charging capacity of one cell can reach 800 mAH. Now, we are combining four cells to provide 3,000 mAH. 200 mAH power. Voltage 3.7V, output 1A."

Everyone else had amazed expressions, only Feng Yu asked blankly: "How much conversion rate can it have?"

The chief engineer looked at Feng Yu with admiration: "Feng is always an expert. Due to technical reasons, the conversion rate of this mobile power supply is not high, only about 65%."

Feng Yu calculated in his heart: "So, the maximum power of this mobile power supply is about 2,000 mAH?"

That's enough, and now a mobile phone battery is only 800 to 1,000. Because the mobile phone does not have many functions, it is enough to use it for a long time. But now that the mobile phone has the MP3 playback function, the power is somewhat insufficient, so this mobile power supply needs to be released as soon as possible.

"We have calculated that the power of 2,000 mAH is enough. It can fully charge two mobile phone batteries, which is enough to meet the user's requirements. For example, on a business trip on the train, or going out for fun." The chief engineer explained.

"Then how much does this mobile power supply cost?" Feng Yuxin said, if you are more expensive than mobile phone batteries, then there is no need to produce them. How about buying two extra mobile phone batteries for backup?

"The direct cost is around 80 RMB."

eighty? Only eighty yuan? Feng Yu was overjoyed, this was much cheaper than the mobile phone batteries that cost more than two hundred yuan at this time!

Um,

No, transportation, storage, advertising, sales and other costs have to be calculated, so the price is 150 yuan, or 20 dollars in foreign countries.

That's cheaper than a mobile phone battery, not to mention, the power of this is equivalent to two batteries.

"Is it only possible to make four batteries in one? Can't there be more?" Feng Yu asked.

"More? Mr. Feng, this is not small. If there are more, wouldn't it be bigger?" The chief engineer looked embarrassed.

Now the size of this power bank is as big as a palm. If there are more, it will become a brick like the old-fashioned mobile phone!

Feng Yu sighed and explained: "Mr. Xiao, think about it, this must be in the bag, right? It's not in your hand, it doesn't matter if it's bigger, the important thing is that the battery should be sufficient. Of course, I am not It is said that this is not good enough now, but that we should provide users with more choices. In this way, you go back and research and get a few more different models.”

"Mr. Feng, what do you mean, this power bank can be launched on the market?" Mr. Xiao was overjoyed. It is very fulfilling for him to make his achievements available to the public and make a profit.

Feng Yu looked at Mr. Xiao with gray hair, excited like a child, and suddenly remembered that this Mr. Xiao must be quite old, right?

"Mr. Xiao, you are not too young. When will you retire?" Mr. Xiao was an expert sent by the electrical machinery factory when we first cooperated.

"Yeah, I'm supposed to retire next year, and I really can't bear to leave." A place where I've worked all my life, and when I'm about to get results, I'm about to leave, so I'm inevitably a little bit reluctant.

"Is Mr. Xiao's family with you?"

"It counts. My son and daughter both work in our Taihua Battery Company, but in different branches. My wife has already retired and takes care of me by my side."

"Mr. Xiao, if you are not afraid of being tired, after you retire, are you interested in re-employing and continuing to work to lead the research and development team of this mobile power supply?" Feng Yu asked with a smile.

It's not that there are no better battery research experts in China, but they are not as familiar with this business as Chief Engineer Xiao, not to mention that Chief Engineer Xiao cooperates with these researchers more tacitly and can hold the field.

Besides, Mr. Xiao received the dead salary from the electrical machinery factory. Although he is a cadre and his rank is not low, his salary is still in the four figures. And those postgraduates and doctoral students newly hired by Taihua Battery Director, after working for three years, their salaries have caught up with Chief Engineer Xiao. Of course, Mr. Xiao's annual bonus is not low, which can be regarded as some compensation from Feng Yu to these state-owned enterprise employees.

Mr. Xiao was overjoyed: "Yes, I don't need any leadership position, just be a researcher."

"That won't work. You have to catch up on technical management. Of course, after re-employment, your salary will be paid according to the standard of the company's vice president. You can't get so much bonus in the future."

"I don't care if I don't want a cent of the bonus!" Although the bonus is large, he could only get 70,000 to 80,000 a year before. But being a vice president is different. The annual salary is 300,000 yuan. Do you still care about those bonuses?

"Mr. Xiao, the next step is to find a way to increase the conversion rate and increase the power of the single cell. It is also necessary to increase the output without damaging the battery life, such as 2A or higher. By the way, if the voltage can It would be better to increase it, such as 19V."

19V? Mr. Xiao immediately understood that this was the voltage of the laptop battery.

"President Feng means that our mobile power bank will be able to charge laptops in the future?"

"It doesn't have to be charging, it can be regarded as a kind of external battery. After all, the battery life of the notebook is not long at this time, and when some business trips, if you need to take the notebook with you, what should you do if it runs out of power? Willing to buy a notebook computer , and use it more frequently, then you will definitely be willing to buy an external battery for our notebook!"

"Okay, Mr. Feng, I understand. It's not too difficult to increase the voltage and current output, but the size will be bigger. Let's find a way to increase the power of the single core and reduce the size and weight."

Feng Yu nodded, then turned to look at Liu Chuanzhi: "Old Liu, then please, go through the back door and apply for the patented technology of this mobile power supply as soon as possible?"

The inventor of this mobile power supply belongs to Taihua Battery, and it belongs to Huaxia! ( )
