Boss Jia was so angry that Wang Chuanfu was so angry.

This Wang Chuanfu was simply crazy. Didn’t he understand what the general trend is and what the inevitability of the future mean?

This guy actually planned to use lead-acid batteries to the source of electric cars, and this kid has completely returned to life.

Although lead-acid batteries are indeed the mainstream now, because the technology is very mature and the production cost is low. The most important thing is that they are extremely safe. Even in this era, there are very few news about lead-acid batteries catching fire and burning.

From this point of view, lead-acid batteries seem to be very suitable for power for electric vehicles, but even Boss Jia, who is in the future, knows that ternary lithium batteries and more advanced iron lithium batteries in the future are the mainstream power sources of electric vehicles, and lead-acid batteries are destined to be eliminated.

Because just like a motor rolls a gasoline engine, lithium batteries also roll the lead-acid battery.

First of all, the energy density of lead-acid batteries is only 13 of lithium batteries, which means that under the same goal of 300 kilometers, the volume and weight of lead-acid batteries are three times that of lithium batteries. In this way, half of the volume and weight of an electric car must be used to place batteries.

Secondly, the lifespan of lead-acid batteries is far less than that of lithium batteries. The number of charges is only about 13 of lithium batteries. An electric car mainly composed of lead-acid batteries may need to be replaced in less than three years.

But lithium batteries can last for 10 years.

Finally, and most importantly, the charging speed of lead-acid batteries is extremely slow. Wang Chuanfu said before that it would take 25 hours to charge, which refers to the charging technology of lithium batteries.

If it is a lead-acid battery, the time will be more than 40 hours.

Moreover, the charging and discharging technology of lithium batteries is only in the early stage of research and development. After all, lithium batteries have only been developed for five years. In the future, with the invention of various fast charging technologies, the charging time of lithium batteries can be compressed to less than one hour.

However, the lead-acid battery will reach its limit at most after compressing to about 20 hours. This is limited by the battery material and there is no way to overcome it.

So if Wang Chuanfu uses lead-acid batteries to build electric cars, such an electric car will definitely become a thing with huge size and weight, and at the same time, the battery life is extremely short and the charging time is extremely long.

In actual use of such an electric car, he is basically an ancestor. Anyone who sees his car needs to change the battery every three years, then drive for 4 hours and charge for 40 hours, is afraid that he will be pissed to death directly.

Otherwise, I really think that all the car companies in the world are short-sighted ghosts. They can’t see that electric cars are the trend of the future industry, and they still hold on to fuel cars?

In fact, as long as these automobile companies are willing, they can land electric cars in at most three years. However, no one is willing to buy such cars. The market prospects are similar to the universe, and it is pitch black, and it takes billions of years.

Not to mention the 1998 years now, even in 2020, there are still many car owners in China who look down on electric cars at all. They are full of mileage anxiety and charging anxiety for electric cars. With various subsidies, license policies, and preferential policies on China, sales of electric cars are still difficult to grow. This is the fundamental reason why they become subsidy frauds!

Boss Jia’s original purpose was to let BYD start to accumulate lithium batteries, iron lithium batteries, and electric vehicle technology. It would be too early to really make electric vehicles online.

But now Wang Chuanfu is better. He just drove back and actually ran back to build an electric car with lead-acid batteries. Even if this kind of car is built, it will definitely not be sold.

"Chairman, listen to me, I know that iron lithium batteries are the future, but lead-acid batteries still have advantages. First of all, the cost is cheap. Although the energy density of lithium batteries is three times that of lead-acid batteries, the production cost of lithium batteries is more than ten times that of lead-acid batteries. In this way, even if the volume is larger, lead-acid batteries are still more cost-effective!"

[PS: It is the current cost, and the cost of lithium batteries in the future is at most about three times higher.]

"Secondly, the stability and safety of lead-acid batteries are unparalleled, and the new generation of lead-acid batteries we have developed have a stability of 10 times that of the old models. I'll guarantee you that even if you have 1 million electric cars, after driving for 10 years, there will be only 2-3 electric cars that will have spontaneous combustion problems!"

"And we also have the technology to control the speed of the battery's spontaneous combustion to ensure that the driver can escape from the spontaneous combustion car with enough time and will not be in danger of life!"

"In addition, we can design an automatic fire extinguishing device to extinguish the flames in the battery compartment as soon as possible."

"Finally, the recyclable performance of lead-acid batteries is also better. We are developing the recycling technology of lead-acid batteries, which can recycle 70% of the raw materials in lead-acid batteries and use them to remanufacturing new batteries, further reducing the manufacturing and recycling costs of batteries. On the contrary, it is difficult to recycle lithium batteries after their lifetime is exhausted, at least in terms of current technology!"

"I don't want to hear any of your reasons!" Boss Jia shook his head. "I admit that what you said may be advantages, but if the most critical problem is not solved, all advantages have no meaning!"

"I know, the problem you are talking about is the charging problem of lead-acid batteries!" Wang Chuanfu nodded.

"Yes, do you want to tell me that Wang Chuanfu got the Einstein dream, and the fast charging method of lead-acid battery that someone told you in the dream can shorten the charging time of lead-acid battery to less than an hour?" Boss Jia said angrily.

"Haha, no, absolutely not. Even if I want to dream of Tesla, I will dream of Einstein. Why do I dream of Einstein? He doesn't care about electricity!" Wang Chuanfu smiled and said, "And I also know that fast charging of lead-acid batteries is difficult. Unless God changes the characteristics of lead-acid batteries, it will be the limit of lead-acid batteries in about 20 hours. Even if I do not want to break this limit in my life!"

"Since you know this, you... aren't right. Do you have other ideas to solve this problem?" Boss Jia was halfway through his words, and suddenly realized that he seemed to be speaking according to those stubborn scripts, while Wang Chuanfu took the protagonist script and was digging a hole to wait for him to jump in!

But then again, if Wang Chuanfu really has a way to solve the charging problem, then the lead-acid battery will not be worthless!

But the question is, how can Wang Chuanfu solve the charging speed problem?
