Chapter 1771 (1/2)

Zheng Chao understands a truth.

It is not afraid to meet a layman in all things, but it is afraid to meet a layman in disguise.

If you can replace the lead-acid battery directly by plugging the lithium battery into the electric vehicle, how can you use him to make a plan here? The people who do electric cars have been doing it for a long time.

In his opinion, Lu Yunhao is a standard outsider and expert in command, which inevitably makes people laugh.

For example, experts know that building a Three Gorges dam is a century project and a super giant project. Apart from China, almost no country can achieve such a scale of water conservancy projects.

In the eyes of people like Lu Yunhao, he will be very disdainful and say: ”isn't it just to build a dam? What's the difficulty? You don't care whether it's a one meter long dam or a one thousand meter, three hundred and thirty-five meter long dam. In terms of technology, it's just two ends of a dam and pouring cement. Isn't that ok? ”

How do you reason with such a person?

But Zheng Chao can't help it. Who let this be his own boss? And I didn't resist the attraction of double salary. I came all the way from Yanjing to join him. Now I can't turn back.

Therefore, he could only bear to say: ”Mr. Lu, I've probably understood that lithium battery is not a general battery. Its biggest problem is that it's not stable enough. If it's just one, it's OK to put it into the flashlight. It's safer. But if there are many strings, the voltage is high and the current is high. In the process of charging and discharging, it's easy to burn and explode. It's not good to return it There will be a fire. ”

”Is it so outrageous?” Lu Yunhao's face was full of disbelief.

”Lithium batteries are not very safe. If you use sharp objects to pierce the lithium batteries of mobile phones, the batteries will be on fire or even explode soon,” Zheng explained

Lu Yunhao asked, ”how did Li Mu do it?”

Zheng Chao said: ”Li Mu has core technology. He can safely string dozens or hundreds of lithium batteries together to make them work stably, without overheating, overcharging, spontaneous combustion or explosion. This is also the biggest technical threshold for domestic electric vehicle manufacturers to imitate. Because domestic electric vehicle manufacturers have not studied these, everything has to start from scratch They don't know how they did it! ”

Lu Yunhao thought, this thing is not to make a big battery box?

Like a four-wheel drive car with two five batteries, you can run when you put them in. An electric car is not big enough to make a bigger battery box. You can run when you put more decorations and a pile of batteries in it.

Now I can roughly understand that there are so many Taoism in it.

Zheng Chao went on to say: ”now the capacity of the lithium battery pack trial produced by several manufacturers is less than half of that of Li Mu's battery pack. There are various problems frequently. The most serious one is that it exploded directly on the testing machine and almost caused a fire. In addition, it's common to overheat, self ignite and charge the battery. It's common to see that one battery pack is stable at present The lithium battery pack for a 100 kilometer trip hasn't been worked out yet. ”

Lu Yunhao was silent for a moment and said, ”let's get the lead-acid battery first, but we need to invest more in it. We need to do a good job in supporting the power exchange. When the electric vehicle manufacturer develops the lithium battery, we need to replace it.”

”As far as I know, electric vehicle manufacturers are basically going to give up R & D,” Zheng said

”Why?” Lu Yunhao frowned and said: ”these guys are too unpromising, aren't they? Fail once or twice and then stop? Don't you know that failure is the mother of success? At the beginning, I wrote a self recommendation letter and a job application letter to the boss of southern English several times before they succeeded. They developed a broken battery, so impatient? ”

”No.” ”I heard them say that there is no market space. If Li Mu's set of hardware is followed, even if there is no technical threshold, the cost of an electric vehicle is more expensive than that of a 125ml motorcycle. If there is no enterprise procurement, ordinary people will not be willing to spend so much money to buy an electric vehicle.”

”Damn it, I'll buy it!” Lu Yunhao said in a hurry: ”if they can really produce the same target as Li Mu, I will buy 300 of them first, oh no, 500...”

Zheng Chao said awkwardly, ”after the R & D is really difficult, if we don't sell 50000 cars, the manufacturer will not be able to pay back...”

If the R & D cost is 10 million yuan and 50000 cars are sold, the R & D cost of each car will account for 200. The manufacturer may not be able to pay back the cost. If only 10000 cars can be sold, the R & D cost of each car is 1000 yuan, let alone the cost.

Therefore, 10000 manufacturers will not be interested, let alone Lu Yunhao's 500.

At this time, another colleague who used to be with southern English knocked on the door and came in. When he saw both of them, he didn't have any taboos. He said directly, ”President Lu, there is still a problem on the business side.”

”What's the problem?”

The other said, ”well, we sent a business team to the nearby hotel and found that almost all the hotels did not have computers.”

”No computer...” Lu Yunhao frowned: ”what do they have to do with us without computers?”

The man was stunned. After a while, he said, ”of course, it's related to President Lu. If they don't have computers, they can't run our order receiving background, and then they can't access our platform...””I wipe...” Lu Yunhao wants to understand.

He already feels a little bit big.

I didn't expect that there would be so much involved in this project.

”Will businesses buy computers?” he asked in a hurry

”No.” ”Most of them are small and medium-sized restaurants, and the retail price of a computer is a little too high for them,” the man said
