Chapter 1361

Boss Jia was mad at Wang Chuanfu.

This Wang Chuanfu is simply stunned. Doesn't he understand what is the general trend and what is the necessity of the future?

This guy actually plans to use lead-acid batteries to the source of electric vehicles. The boy has completely survived.

Although the lead-acid battery is indeed the mainstream now, because the technology has been very mature, the production cost is low, and the most important thing is the high safety, anyway, even in this era, we rarely hear the news of lead-acid battery burning.

In this way, the lead-acid battery seems to be very suitable for the power of electric vehicles, but even boss Jia, who is in the future mixed P station, knows that the ternary lithium battery and the more advanced iron lithium battery in the future are the mainstream power source of electric vehicles, and the lead-acid battery is destined to be eliminated.

Because like the motor rolling gasoline engine, the performance of lithium battery is also rolling lead-acid battery.

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

Secondly, the life of lead-acid battery is far less than that of lithium battery, and the charging times are only about 13 times that of lithium battery. An electric vehicle dominated by lead-acid battery may need to replace the battery in less than three years.

But lithium batteries can last 10 years.

Finally, and most importantly, the charging speed of lead-acid battery is very slow. Wang Chuanfu said that it takes 25 hours to charge, which refers to the charging technology of lithium battery.

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

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

However, the lead-acid battery will reach the limit after being compressed for about 20 hours at most. This is the limitation of battery materials and there is no way to overcome it.

Therefore, if Wang Chuanfu uses lead-acid batteries to make electric vehicles, such electric vehicles will inevitably become things with huge volume and weight, extremely short battery life and extremely long charging time.

In the actual use of such an electric vehicle, it is basically an ancestor. Whoever sees that his car has to change the battery every three years, then drive for 4 hours and charge for 40 hours, I'm afraid he won't be killed directly.

Otherwise, I really think that all automobile enterprises in the world are short-sighted. They can't see that electric vehicles are the trend of the future industry. Do they still cling to fuel vehicles?

In fact, as long as these automobile enterprises are willing, they can land electric vehicles in up to three years. However, no one will be willing to buy such vehicles. The market prospect is almost the same as the universe. It is dark for billions of years.

Not to mention the current 98 years, even by 2020, there are still many car owners in China who don't care about electric vehicles at all. They are full of mileage anxiety and charging anxiety about electric vehicles. Under various subsidies, license policies and purchase tax policies in China, it is still difficult for sales to grow, and finally become a thing to cheat subsidies. Here is the fundamental reason!

Boss Jia's original purpose is to let BYD start to accumulate about lithium batteries, iron lithium batteries and electric vehicle technology. It's too early to really want to put electric vehicles online.

But now Wang Chuanfu is in a good position to directly reverse the history and run back to use lead-acid batteries to make electric cars. Even if such cars are made, they will never be sold.

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

[PS: it's the current cost. In the future, the cost of lithium battery will be about three times higher at most.]

"Secondly, the stability and safety of lead-acid batteries are unparalleled, and the stability of our newly developed new generation of lead-acid batteries exceeds 10 times that of the old ones. I'm here to assure you that even if 1 million electric vehicles drive for 10 years, only 2-3 electric vehicles will have the problem of spontaneous combustion!"

"Moreover, we also have technology to control the speed of battery spontaneous combustion, so as to ensure that the driver can escape from the spontaneous combustion car in enough time, and there will be no danger of life!"

"In addition, we can design an automatic fire extinguishing device to extinguish the flame in the battery compartment at the first time."

"Finally, the recyclability of lead-acid batteries is better. We are developing the recycling technology of lead-acid batteries, which can recycle 70% of the raw materials in lead-acid batteries for remanufacturing new batteries, further reducing the manufacturing cost and recycling cost of batteries. On the contrary, it is difficult to recycle lithium batteries after their service life is exhausted, at least in terms of current technology ！”

"I don't want to hear your reasons!" boss Jia shook his head. "I admit that these may be advantages, but if the most critical problems are not solved, all advantages are meaningless!"

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

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

"Oh, no, absolutely not. Even if I want to dream, I also dream of Tesla. What does Einstein dream about? He doesn't care about electricity!" Wang Chuanfu smiled "And I also know that the fast charging of lead-acid battery is very difficult. Unless God changes the characteristics of lead-acid battery, about 20 hours is the limit of lead-acid battery. Even if I don't want to break this limit all my life!"

"Now that you know this, you still... No, you boy, do you have another idea to solve this problem?" when boss Jia was half talking, he suddenly found that he seemed to be speaking according to those old and stubborn scripts, while Wang Chuanfu took the leading role script and was digging a hole waiting for him to jump in!

But then again, if Wang Chuanfu really has a way to solve the problem of charging, the lead-acid battery will not be of no use value!

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

"Chairman, my idea is very simple. Since the charging speed is difficult to break through, we simply don't study how to improve the charging speed, and even our electric vehicles don't need to be charged!" Wang Chuanfu said aloud his idea "we don't charge, let's directly change the battery!!!"
