Reborn Entrepreneurial Giant.

Chapter 430 Specific choices

In order to make better decisions, Qu Li called Zhu Yiming, the founder of GigaDevice Innovation, for consultation. He has now entered the senior management of Spansion Semiconductor.

Spansion Semiconductor is still controlled by Vision Investment and is an asset-light model. Its main products are NOR and NAND flash memory. It is one of the main suppliers of Honor through Changjiang Storage OEM.

"How was your performance at Zipline?" Qu Li asked Zhu Yiming

"Many Tsinghua alumni have joined, and we have a say in the company..."

"I need Spansion Semiconductor to transform into automotive semiconductors. Do you have experience in this area?" Qu Li felt that only Infineon was unreliable and had too weak control.

"Zipso's MCU ranks among the top 10 in the world..." Zhu Yiming

"As for R&D capabilities, I want Zhongguo to no longer be controlled by others in the field of automotive semiconductors, but I am also afraid that your lack of strength will affect our brand..." Qu Li directly stated his thoughts and did not let him guess.

"I can't guarantee this, but Spansion is already the best semiconductor design company in the country, and our domestic team is growing very fast..."

Qu Li asked for some more details. He was neither satisfied nor disappointed. Spansion Semiconductor's revenue had increased and it had escaped the risk of bankruptcy. However, although Vision Investment was the major shareholder, there were other shareholders. He was not the one who wanted to enter the automotive semiconductor industry. It can be settled in one sentence, but then you have to pay for it.

Qu Li was in the process of asset segregation with Vision Investment at this time. He originally planned to give up control of Spansion Semiconductor. If Honor needed it, he would have to retain it. He had to make the final decision on many things, which was really annoying.

Zhang Yiwen built a luxurious villa in Xingsha, which covers a large area. Qu Li lives here in his spare time. April is the most comfortable time in Xingsha, with bright sunshine and gentle wind.It was a good time to create a man. Not only did she think of ways to replenish his body, but she also thought of ways to drain him. The matter of mutual love turned into a burden...

There was no other way, so Qu Li had to take the initiative to find a job for himself, such as going to Honor's power battery company. The number of employees now does not exceed 100, all of them are developers. The average education level per person is a bachelor's degree or above, which is equivalent to a large experimental base, which is like Honor. Rich people can afford this kind of institution that only has input but no output.

Although Qu Li doesn’t understand top speed, he understands management and knows that in addition to improving the chemical composition of power batteries, there are also structural innovations and manufacturing process improvements. In addition, by improving the integration of batteries and other systems, the performance and efficiency of the entire electric vehicle can be improved. , such as kinetic energy recovery.Solid-state, sodium-ion batteries are also the direction of improvement and innovation.

Qiancheng's pure electric vehicles currently use 18650 batteries produced by Panasonic purchased from Tesla. Not to mention the high cost, it is not a good thing to be controlled by others, so they chose square batteries and 2170 cylindrical batteries.

The reason why we do not give up on cylindrical batteries is because the winding process is mature, highly automated, high production efficiency, good consistency, and relatively low cost. The disadvantages are low space utilization, large number of cells, complex BMS battery management, and difficulty Very big.

The structure of the square battery is relatively simple, so the overall accessories should be light in weight, the number of batteries needed is small, and the BMS management system requirements are lower. It can be customized for production. The disadvantage is that because there are too many models, the process is difficult to unify, and the production The level of automation is not high and the individual units vary greatly.

I still have to use BYD as an example. I really don’t blame him. Tesla cars using 2170 batteries have fewer spontaneous combustion accidents than BYD cars using “blade” batteries. The reason for this is nothing more than the poor consistency of BYD’s batteries: manufacturing level not enough.

So why doesn't BYD use cylindrical batteries?Of course, the BMS battery management system is more complex and difficult to solve, and the upper limit is not as high as that of prismatic batteries.In other words, most of the problems BYD encounters can be solved through time. We are optimistic about their long-term competitiveness. As long as autonomous driving is a false proposition in the short term, it is only a matter of time before BYD surpasses Tesla.

Honor's situation is different from that of BYD. It has not yet determined whether it will be a brand or a pure electric vehicle solution provider. It is not a bad thing to become China's Bosch.The direction of Chrysanthemum Factory is not wrong, but there are problems with selecting and employing people. Yu Dazui has succeeded in building consumer terminals, but what service companies want is not to brag, but to help companies solve problems down-to-earth.But Mr. Zheng Fei is suffering from the disease of big business, and Yu Dazui is the hero. Since he has issued a military order, it is impossible not to give him a chance.

Qu Li doesn't have so many things to think about now. He focuses on ternary lithium batteries and develops prismatic and 2170 batteries at the same time.

为什么不是18650电池？因为2170的性价比更高，18650电池技术虽然比较成熟，但锂离子容量一般在2000mAh到3200mAh之间，能量密度在250Wh/kg左右；而2170电池容量介于3000mah至5000mah两者之间，能量密度在300Wh/kg左右。

Taking the Tesla model S as an example, it uses 7104 18650 batteries, while the lower-positioned model 3 only uses 4416 2170 batteries, making the vehicle lighter.

Later, many traditional major manufacturers used 2170 batteries, and domestic advantages in prismatic batteries were more obvious, so differences formed.

Qu Li didn’t know who represented the future. It might be solid-state batteries, so he invested in both square and cylindrical directions. He also added insurance and invested in CATL.

Give your own people motivation, but also put pressure on them to ensure that the companies that can stay in the Honor supply chain are excellent. Therefore, including Zhu Yiming of GigaDevice and others, they both love and hate Qu Li.

Most people can understand Qu Li's choice. Even if they don't, he doesn't care. Honor has the ability to integrate the supply chain. Without unique technology or indispensable status, it has to be obedient. Not everyone can stand up and take care of it. Money is made, and everyone succeeds.

After walking around the power battery company, Qu Li was somewhat relieved to learn that the prismatic battery production line was already under construction.There are still many difficulties ahead for Qiancheng Automobile, and he can't get involved in most things. He can make the decision only on things that don't require technical judgment and rely more on market intuition, such as the hybrid cars being developed.

There is no doubt that Qu Li imitated BYD DMI and DMP. Even if it takes more than 20 or 60 years, BYD will be a symbol that is difficult for domestic automobile companies to bypass. This company has equally outstanding advantages and disadvantages. It manages [-] million employees. It’s not an easy thing, wish them good luck.

Qu Li is a technology product enthusiast and has some knowledge of BYD's DMI and DMP. He has seen some structural diagrams on the Internet and knows that one is a front-wheel drive with two wheels and the other is a four-wheel drive; one focuses on energy saving while taking into account performance, and the other focuses on performance. Mainly taking into account energy saving.

The direction is right, and the speed of progress will naturally be fast. There is no suspense for Honor to surpass BYD. I'm sorry for the boatman. Qu Li mourned for him for a few seconds, and then returned to the Automobile Research Institute in Xingsha to make plans for Qiancheng's third car. direction, a four-wheel drive off-road vehicle.
