Reborn Entrepreneurial Giant

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

Spansion Semiconductor is still controlled by Envision Investment. It 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 are you doing on the zip line?" Qu Li asked Zhu Yiming

"A lot of Tsinghua alumni joined us, and we have the right to speak in the company..."

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

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

"The research and development capabilities, I want Zhongying to no longer be controlled by others in the field of automotive semiconductors, and I am afraid that your lack of strength will affect our brand..." Qu Li directly expressed his thoughts without letting him guess.

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

Qu Li asked some more details. He was neither satisfied nor disappointed. Spansion Semiconductor’s income increased and it got rid of the risk of bankruptcy. However, although Vision Investment is the major shareholder, there are other shareholders. It is not him who wants to enter the automotive semiconductor industry. It can be settled in one sentence, and you have to pay for it when the time comes.

At this time, Qu Li was separating assets from Vision Investment. He originally planned to give up control of Spansion Semiconductor. If Glory needed it, he had to keep it. He had to make decisions on many things, which was really annoying.

Zhang Yiwen built a mansion villa in Xingsha, which covers a large area. Qu Li lives here in his spare time. April is the most comfortable time in Xingsha, the sun is shining and the wind is beautiful. It was a good time to make a man. Not only did she find a way to replenish his body, but she also wanted to squeeze him dry. The love between the two became a burden...

No way, Qu Li had to take the initiative to find a job for himself, such as going to Glory’s power battery company. Currently, the number of employees does not exceed 100, and they are all developers. Local tyrants can afford to support this kind of institution that only has input but no output.

Although Qu Li doesn't understand extreme speed, he understands management and knows that the direction of power batteries is not only chemical composition improvement, but also structural innovation and manufacturing process improvement; 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 directions for improvement and innovation.

Qiancheng's pure electric vehicles currently use 18650 batteries purchased from Tesla and produced by Panasonic. 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 the cylindrical battery is not given up is because the winding process is mature, the degree of automation is high, the production efficiency is high, the consistency is good, and the cost is relatively low. The disadvantage is that the space utilization rate is low, the number of cells is large, and the BMS battery management is complicated and difficult. very big.

The structure of the square battery is relatively simple, so the weight of the overall accessories is light, the number of batteries needed is small, and the requirements of the BMS management system are lower, and customized production is possible. The disadvantage is that because there are too many models, the process is difficult to unify. The level of automation is not high, and the individual differences are large.

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

Why doesn't BYD use cylindrical batteries? Of course, the BMS battery management system is more complicated and more difficult to tackle, and the upper limit is not as high as that of the square battery. In other words, most of the problems encountered by BYD 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.

The situation of Glory is different from that of BYD. It has not yet been determined whether it is a brand or a solution provider for pure electric vehicles. It is not a bad thing to become China's Bosch. The direction of the Chrysanthemum Factory is not wrong. There is a problem with choosing and employing people. Yu Dazui has succeeded in making a consumer terminal, but what the service company wants is not to brag, but to help the company solve problems down-to-earth. However, Mr. Ren Zhengfei is suffering from the disease of large enterprises, and Yu Dazui is a hero. Now that the military order has been issued, it is impossible not to give him a chance.

Qu Li does not have so many things to consider now, focusing on ternary lithium batteries, while developing square and 2170 batteries.

Why not 18650 batteries? Because the 2170 is more cost-effective, although the 18650 battery technology is relatively mature, the lithium ion capacity is generally between 2000mAh and 3200mAh, and the energy density is around 250Wh/kg; while the 2170 battery capacity is between 3000mah and 5000mah, and the energy density Around 300Wh/kg.

Taking the Tesla model S as an example, 7104 18650 batteries are used, while the lower-positioned model 3 only uses 4416 2170 batteries, and the vehicle is lighter in weight.

Later, many traditional manufacturers used 2170 batteries, and the domestic advantages in square batteries were more obvious, so there was a difference.

Qu Li doesn't know who represents the future, maybe it's solid-state batteries, so he invests in both the square and the cylinder, and adds an insurance to invest in CATL.

To give motivation to our own people, we must also put pressure on them to ensure that the companies that can stay in the glory supply chain are all excellent, so Zhu Yiming and others, including Zhaoyi Innovation, love and hate Qu Li.

Most people can understand Qu Li's choice, even if he doesn't understand, he doesn't care, Glory has the ability to integrate the supply chain, without unique technology, without an indispensable position, you have to be obedient, not everyone can stand up Money is earned, and everyone achieves each other.

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

There is no doubt that Qu Li imitated BYD's DMI and DMP. Even after ten or twenty years, BYD will be a symbol that domestic auto companies cannot bypass. The advantages and disadvantages of this company are equally prominent. It's not an easy job for your employees, good luck to them.

Qu Li is a lover of technology products. He still has some understanding of BYD's DMI and DMP. He has seen some structural diagrams on the Internet and knows that one is a front-wheel two-wheel drive and the other is a four-wheel drive; one is energy-saving and performance-oriented, and the other is performance. Taking energy saving into consideration.

If the direction is right, the forward speed will naturally be fast. There is no suspense that the glory will surpass BYD. I'm sorry for the boatman. Direction, a four-wheel drive off-road vehicle.
