Feng Yu found the Fu family to help operate the listing of Aihua Xiaobawang in Xiangjiang, and at this time, another good news appeared. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Taihua Battery Company has finally completed one of Feng Yu's plans, which is to produce mobile power supplies. Before, this was just a concept, 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 a foreign student in the United States, using a few dry batteries through a small circuit device, which can be converted into a current that can charge a mobile phone. The first place to appear was the consumer electronics exhibition in the United States.

But now, the exhibition hasn't opened yet, and it is estimated that the mobile power supply has not yet been completed. Although he claims to be launching a mobile power bank soon, this statement has been mentioned for a few months, but there is still no belief at all?

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

"Look, we use a high-energy lithium battery, designed as a column, and one cell can charge up to 800mAh, and we are now combining four cells, so we can provide 3,200mAh of electricity. The voltage is 3.7V, and the output is 1A. ”

Everyone else had an expression of amazement, only Feng Yu asked expressionlessly, "How much conversion rate can be?" ”

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 sixty-five percent." ”

Feng Yu calculated in his heart: "So, the power of this mobile power bank is only about two thousand mAh at most?" ”

That's enough, and now the power of a mobile phone battery is only 800 to 1,000. Because the phone doesn't have many features, the use time is still sufficient. But now that the mobile phone has the mp3 playback function, these powers are a little insufficient, so this power bank needs to be launched as soon as possible.

"Two thousand mAh of power, we have calculated, is enough, can fully charge two mobile phone batteries, enough to meet the user's requirements. For example, on a business trip on the train, or going out to play or something. The chief engineer explained.

"And how much does this power bank cost?" Feng Yuxin said, if you are more expensive than a mobile phone battery, then it will be produced soon, how good would it be for people to buy two more mobile phone batteries for backup?

"The direct cost is about eighty RMB."

Eighty? Only eighty dollars? Feng Yu was overjoyed, this is much cheaper than the mobile phone battery that costs more than 200 yuan at this time!

Well, no, you have to calculate other costs such as transportation, storage, advertising, sales, etc., so how can the price be 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.

"Can you only make four cells in one? Can't 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 mobile power bank has caught up with the size of the palm, if it is more, it will not be the same as the old-fashioned big brother, become a brick!

Feng Yu sighed and explained, "Chief Engineer Xiao, think about it, this must be in the bag, right?" It's not in your hand, it's okay if it's bigger, the important thing is that the power is sufficient. Of course, I'm not saying that this is not good enough right now, but we should give users more options. In this way, you go back and look into it and get a few more different models to come out. ”

"Mr. Feng, what do you mean, this mobile power supply can be launched to the market?" Chief Engineer Xiao was overjoyed. It is very rewarding for him to be able to make his results available to the public and make a profit.

Feng Yu looked at Chief Engineer Xiao with gray hair, excited like a child, and suddenly remembered, this Chief Engineer Xiao's age should not be young, right?

"Chief Engineer Xiao, you are not too young, when will you retire?" Chief Engineer Xiao was an expert sent by the motor factory when he first cooperated.

"yes, I'm going to retire next year, and I'm really reluctant to leave." After working all my life, and when I was about to make results, I was about to leave, and I was inevitably a little reluctant.

"Is Chief Engineer Xiao's family with you?"

"Count it in. My son and daughter both work in our Taihua battery company, but in different branches. My wife is long retired and takes care of me by my side. ”

"Chief Engineer Xiao, if you are not afraid of being tired, then after you retire, are you interested in returning to work and leading the R&D 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 has a more tacit understanding with these researchers, and he can still hold the scene.

Besides, Chief Engineer Xiao gets a dead salary from the motor factory, although he is a cadre and his level is not low, but the salary is still four figures. And the newly hired graduate students and doctoral students of Taihua Battery, after three years of work, the salary has caught up with Chief Engineer Xiao. Of course, Chief Engineer Xiao's annual bonus is not low, which can be regarded as some compensation from Feng Yu to the employees of these state-owned enterprises.

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

"That's not going to work, technical management, you still have to arrest it. Of course, after being rehired, your salary will be paid according to the standard of the company's vice president, and you will not be able to get so much in the future. ”

"I don't want a penny!" Although the bonus is much, he can get seventy or eighty thousand a year before, although there is a lot of it, but he is embarrassed to take too much. But being a vice president is different, what about an annual salary of 300,000 yuan, do you still care about those bonuses?

"Chief Engineer Xiao, the next step is to find a way to improve the conversion rate, and also to increase the power of a single core. Also increase the output, such as 2A or higher, without damaging battery life. By the way, it would be better if the voltage could be increased, such as 1. ”

1？ Chief Engineer Xiao immediately understood that this was the voltage of the laptop battery.

"What does Mr. Feng mean, our mobile power bank, should be able to charge the laptop in the future?"

"It's not necessarily charging, it can be regarded as an external battery. After all, the battery of the laptop is not used for a long time at this time, and when you are on a business trip, if you need to bring the laptop, what should you do if the battery is out? If you are willing to buy a laptop and use it more frequently, then you will definitely be willing to buy the external battery of 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 a single core and reduce the size and weight."

Feng Yu nodded, then turned his head to look at Liu Chuanzhi: "Lao Liu, then trouble you, go through the back door, and apply for the patented technology of this mobile power supply quickly, right?" ”

The inventor of this mobile power supply is Taihua battery, and it is our Huaxia!
