Feng Yu found a family member to help organize the listing of Aihua Xiaobawang in Hong Kong. At this time, another good news appeared.
Taihua Battery Company finally completed one of Feng Yu's plans, which was to produce mobile power supplies. Before, this was just a concept. Many companies claimed to have researched it, but none of them launched a product.
It is said that the world's first small mobile power supply was invented by an overseas student in the United States. It used several dry batteries and converted them into current that can charge mobile phones through a small circuit device. The first place it appeared was at the Consumer Electronics Show in the United States.
But right now, the trade fair hasn’t started yet, and the mobile power supply is probably not finished yet. Although Sunny claims that it will soon launch a mobile power supply, it has been mentioned for several months, and there is still no faith at all
The chief engineer of Taihua Battery Company brought the sample to Fengyu Building in Beijing and showed Feng Yu this mobile power supply in Feng Yu's office.
"Please see, we use high-energy lithium batteries, which are designed in a columnar shape. The charging capacity of one battery cell can reach 800 mAH. Now, we combine four battery cells, which can provide 3,000 mAH." Two hundred mAH power. Voltage, output 1A."
Everyone else had expressions of amazement on their faces. Only Feng Yu asked expressionlessly: "What's the conversion rate?"
The chief engineer looked at Feng Yu with admiration: "Mr. Feng is 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 mind: "So, the power of this mobile power supply is only about 2,000 mAH at most?"
That's enough. Now a mobile phone battery only has 800 to 1,000 charges. Because the phone does not have many functions, the usage time is still enough. But now that mobile phones have the MP3 playback function, the power is somewhat insufficient, so this mobile power supply needs to be available as soon as possible.
"We have calculated that the power of two thousand mAH is enough to fully charge two mobile phone batteries, which is enough to meet the user's usage requirements. For example, on a business trip on the train, or out for fun," the chief engineer explained.
"Then how much does this mobile power supply cost?" Feng Yuxin said, if it is more expensive than a mobile phone battery, then stop producing it. How about buying two more mobile phone batteries for backup
"The direct cost is about 80 RMB."
eighty? Only eighty yuan? Feng Yu was overjoyed. This was much cheaper than mobile phone batteries that cost more than 200 yuan at this time!
Well, no, we also need to calculate other costs such as transportation, storage, advertising, sales, etc., so the price is one hundred and fifty yuan. If it is abroad, it will be twenty dollars.
That's cheaper than a mobile phone battery, not to mention, the power of this one is equivalent to two batteries.
"Can it only be made with four batteries in one? Can't there be more?" Feng Yu asked.
"More? Mr. Feng, this is already quite big. If it's more, wouldn't it be bigger?" The chief engineer looked embarrassed.
Now the size of this mobile power supply is as big as a palm. If it were larger, it would become a brick like the old-fashioned mobile phone!
Feng Yu sighed and explained: "General Manager Xiao, think about it, this must be put in the bag, right? It's not held in the hand, it doesn't matter if it is bigger, the important thing is that the battery must be sufficient. Of course, I am not It is said that the current one is not good enough, but we should provide users with more choices. In this way, you can go back and study it and come up with a few more different models."
"Mr. Feng, do you mean that this mobile power supply can be launched on the market?" Mr. Xiao was overjoyed. Being able to make his achievements available to the public and make a profit is a very fulfilling feeling for him.
Feng Yu looked at the gray-haired Chief Engineer Xiao, as excited as a child. He suddenly remembered that this Chief Engineer Xiao must be quite old, right
"General Engineer Xiao, you are quite old, aren't you? When will you retire?" General Engineer Xiao was an expert sent by the Electrical Machinery Factory when we first cooperated.
"Yes, I should retire next year, and I really can't bear to leave." I'm leaving a place where I've worked all my life, and just when I'm about to produce results, so I'm inevitably a little bit reluctant to leave.
"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 retired long ago and is by my side to take care of me."
"General Engineer Xiao, if you are not afraid of getting tired, would you be interested in returning to work and leading this mobile power supply R&D team after retirement?" Feng Yu asked with a smile.
It's not that there aren't better battery research experts in the country, but none of them are as familiar with this business as Chief Engineer Xiao. What's more, Chief Engineer Xiao also has a better understanding of cooperation with these researchers and can hold their own.
Besides, Chief Engineer Xiao received a dead salary from the electrical machinery factory. Although he was a cadre and his rank was not low, his salary was still four digits. As for the graduate students and doctoral students newly hired by Taihua Battery Manager, after working for three years, their salaries are as high as those of 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 them, state-owned enterprise employees.
Chief Engineer Xiao was overjoyed: "Yes, I don't need any leadership position, I just need to be a researcher."
"That won't work. You still have to catch up on technical management. Of course, after you are re-employed, your salary will be paid according to the standards of the company's vice president. You will not be able to get that much in the future as a project bonus."
"I don't need even a cent of the bonus!" Although the bonus was large, he could only get 70,000 to 80,000 yuan a year before. Although there was a lot of money from above, he was embarrassed to take too much. But it's different when you become a vice president. With an annual salary of 300,000 yuan, do you still care about those bonuses
"General Manager Xiao, next we need to find ways to improve the conversion rate, and also increase the power of a single cell. We also need to increase the output without damaging the battery life, such as 2A or higher. By the way, if the voltage can If it is improved, it would be better, such as 19V.”
19V? Manager Xiao immediately understood that this was the voltage of the laptop battery.
"Mr. Feng, what do you mean, our mobile power supply can charge laptops in the future?"
"It's not necessarily charging, it can be regarded as a kind of external battery. After all, the battery life of laptops is not very long at this time, and when you go on a business trip, if you need to take your laptop with you, what should you do if the battery runs out? Are you willing to buy a laptop? , and it is used more frequently, then you will definitely be willing to buy an external battery for our notebook!”
"Okay, Mr. Feng, I understand. It is not too difficult to increase the voltage and current output, but it will be larger. We will find a way to increase the power of a single core and reduce the size and weight."
Feng Yu nodded, then turned to look at Liu Chuanzhi: "Old Liu, can I trouble you to use a back door to 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 China!
