"Is Chief Engineer Xiao's family with you?"
There were rumors that the world's first portable power source was invented by an overseas student in the US. It uses a few dry batteries, and through a small circuit, it can be used to charge a mobile phone. It was first introduced in the US during the Consumer Electronics Exhibition.
It's not that there are no better battery researchers in China. But none of them are as familiar with this industry as Chief Engineer Xiao. Furthermore, Chief Engineer Xiao has good teamwork with the researchers and is able to control the situation.
"No. You still have to be in charge of the technical management. Of course, after you are rehired, your salary will be the same as the company's Deputy General Manager. You will not be getting so much bonus for your research in the future. "
Tai Hua Battery had finally completed one of Feng Yu's projects. It is to produce portable power sources. This was only a concept in the past. Many companies had researched on this technology, but none of them had launched a product.
"I don't mind even if I don't get any bonus!" Although the bonus was high, he was only getting 70,000 to 80,000 RMB a year. Although the higher-ups had given him a lot of bonus, he does not want to take too much. But it's different now that he is a Deputy General Manager. His annual salary is 300,000 RMB, and he does not care about the bonus.
"How much is the cost of this portable power source?" Feng Yu replied. If this portable power source is more expensive than the mobile phone batteries, then there is no need to produce it. People can just buy two spare mobile phone batteries.
"You can only combine four batteries into one battery? Can't it be more than that? "Feng Yu asked.
Feng Yu had asked the Fu Family to help with Aiwa's listing in Hong Kong. At this time, another piece of good news appeared.
"More? General Manager Feng, this is not a small amount. If you want more, it will be bigger. "Chief Engineer Xiao was troubled.
"General Manager Feng, are you saying that this portable power source can be introduced to the market?" Chief Engineer Xiao was overjoyed. He felt a sense of achievement to be able to introduce his research to the public and get profits from it.
"We had calculated that 2,000 mAH of battery is enough to fully charge two mobile phone batteries. It is enough to meet the user's needs. For example, on the train or out on a holiday. "Chief Engineer Xiao explained.
Feng Yu did some mental calculations. "So, this portable power supply's maximum capacity is only about 2,000 mAH?"
"Chief Engineer Xiao, you are not young anymore. When are you going to retire?" Chief Engineer Xiao was an expert sent over by the Motor Factory.
That was still cheaper than a cell phone battery. Moreover, the power of this was equivalent to two batteries.
Hmm, that's not right. I still have to calculate transportation, storage, advertising, sales, and other costs. The price will be 150 yuan, or 20 USD overseas.
"It doesn't have to be a rechargeable battery. It can be considered an external battery. After all, the battery life of the laptop wasn't long at this time. If he needed to bring the laptop on a business trip, what would he do if it ran out of battery? Those who are willing to buy a laptop and use it frequently will definitely be willing to buy the external battery for our laptop! "
"Count me in as well. My son and daughter are working at Tai Hua Battery Company, but they are in different factories. My wife has already retired and is taking care of me by my side. "
Feng Yu sighed and explained. "Chief Engineer Xiao, think about it. This battery should be in your bag, right? It's not like you are holding it in your hands, and it doesn't matter if it is bigger. Of course, I am not saying that the current battery is not good enough. But we should give the users more choices. Why don't you go back and do some research and come up with a few different models? "
"General Manager Feng, are you saying that our portable power supply can be used to charge laptops in the future?"
The inventor of this portable power supply is Tai Hua Battery and Hua Xia!
But now, the exhibition is not held yet, and the portable power supply is not ready yet. Although Sony claims that they will introduce the portable power supply soon, it had been months, and there is still no news.
Feng Yu looked at the white-haired Chief Engineer Xiao excitedly like a child. Suddenly, he remembered that this Chief Engineer Xiao should be quite old.
"The direct cost is about 80 RMB."
… …
"Chief Engineer Xiao, we must think of ways to increase the conversion rate and the battery capacity of the single cell. We must also increase the output without affecting the battery's lifespan. For example, 2A or higher. Oh, it will be better if we can increase the voltage. For example, 19V. "
The Chief Engineer looked at Feng Yu with admiration. "General Manager Feng is an expert. Due to technical reasons, the conversion rate of this portable power supply is not high. It's only about 65%."
80 RMB? Only 80 RMB? Feng Yu was overjoyed. This is much cheaper than the mobile phone batteries, which cost more than 200 RMB!
Tai Hua Battery's Chief Engineer brought the sample to Beijing's Wind and Rain Building to show Feng Yu this portable power supply in his office.
"Ok, General Manager Feng. I understand. It is not difficult to increase the voltage and current output, but it will be bigger. We must think of ways to increase the battery capacity and reduce the size and weight."
19V？ Chief Engineer Xiao immediately understood. This is the laptop battery's voltage.
"Chief Engineer Xiao, if you are not tired, are you interested in coming back to lead this mobile power supply research team after you retire?" Feng Yu smiled and asked.
Chief Engineer Xiao was overjoyed. "Yes. I don't need any leadership positions. I just want to be a researcher."
Everyone else was shocked. Only Feng Yu asked emotionlessly. "What is the conversion rate?"
"Everyone, please take a look. We are using high-efficiency lithium batteries, and it is designed to be cylindrical. One battery can charge up to 800 mAH. Now, we are using 4 batteries, and we can charge up to 3200 mAH. The voltage is 3.7V, and the output is 1A. "
The size of this portable power supply is about the size of a palm. If there are more batteries, it will be like an old-fashioned mobile phone. It will be a brick!
Furthermore, Chief Engineer Xiao is getting a fixed salary from the Motor Factory. Although he is a staff member and has a high rank, his salary is still 4 digits. Also, Tai Hua Battery's newly hired postgraduate students and doctoral students are getting higher salaries than Chief Engineer Xiao after working for 3 years. Of course, Chief Engineer Xiao's annual bonuses are not low. This is considered as compensation from Feng Yu to these state-owned enterprises' employees.
"That's right. I will be retiring next year, and I can't bear to leave." Chief Engineer Xiao had worked at this place for his whole life, and he will be leaving just when he is about to achieve results.
Feng Yu nodded and turned to Liu Chuanzhi. "Old Liu, I will need to trouble you to apply for the patent for this mobile power supply. Can you help me apply for the patent now?"
That will be enough. Currently, a mobile phone's battery capacity is only 800 to 1,000 mAH. Because mobile phones do not have many functions, they can still use it for a long time. But now, mobile phones have MP3 players, and the batteries are not enough. That's why this portable power supply needs to be introduced into the market as soon as possible.
