Boss Jia was infuriated by Wang Chuanfu.
This Wang Chuanfu was crazy. Did he not understand what it meant to be inevitable in the future?
This guy actually planned to use lead-acid batteries as the source of electric cars. This guy had completely gone back in time.
Although lead-acid batteries were indeed the mainstream because the technology was very mature and the production cost was low. Most importantly, it was very safe. Even in this day and age, it was very rare to hear about lead-acid batteries catching fire.
Looking at it this way, lead-acid batteries did seem to be very suitable for electric scooters. But even Boss Jia, who was a futuristic VP, knew that the lithium battery and the more advanced lithium battery in the future were the main sources of power for electric scooters. The lead-acid battery was destined to be eliminated.
Because just like how electric motors crushed gasoline engines, lithium batteries also crushed lead-acid batteries.
First of all, lead-acid batteries only had a third of the energy density of lithium batteries. This meant that for the same 300km range, the size and weight of lead-acid batteries were three times that of lithium batteries. This way, an electric car's size and weight had to be used to store batteries.
Secondly, the lifespan of lead-acid batteries was far less than lithium batteries. The number of charges was only about a third of lithium batteries. An electric car that mainly used lead-acid batteries would need to be replaced in less than three years.
However, lithium batteries could last for 10 years.
Lastly, and most importantly, lead-acid batteries' charging speed was extremely slow. Wang Chuanfu said that it would take 25 hours to charge, but that was referring to lithium batteries' charging technology.
If it was lead-acid batteries, then it would take more than 40 hours.
Moreover, the lithium battery charging technology was still in the early stages of development. After all, lithium batteries had only been developed for five years. In the future, with the invention of various fast charging technologies, lithium batteries' charging time could be compressed to less than an hour.
However, lead-acid batteries could only be compressed to around 20 hours before reaching their limit. This was due to the limitations of the battery material. There was no way to overcome this limitation.
Therefore, if Wang Chuanfu used lead-acid batteries to make electric cars, then the electric cars would definitely be large and heavy. At the same time, the battery life would be extremely short, and the charging time would be extremely long.
This kind of electric scooter was basically an ancestor when used in real life. Whoever saw their own car needing to change the battery every three years, then driving for 4 hours and charging for 40 hours would probably be angered to death.
Otherwise, do you really think that all the automobile companies in the world are short-sighted? Can't they see that electric vehicles are the future of the industry? Why are they still clinging to gasoline-powered vehicles?
As a matter of fact, as long as these automobile companies were willing, they could have electric cars on the market in three years at most. However, no one would be willing to buy such cars. The market prospects were similar to the universe, pitch-black. It would take billions of years.
Even in 2020, there were still a lot of car owners in Hua Xia who looked down on electric cars. They were anxious about the range and charging of electric cars. Electric cars had all sorts of subsidies from Hua Xia, as well as license plate policies and purchase tax incentives, but sales still couldn't increase. In the end, electric cars became a tool to cheat subsidies!
Boss Jia's original intention was to let BYD start developing lithium and iron-lithium batteries, as well as accumulating knowledge on electric scooters. It was still too early for them to actually make electric cars on the market.
But now, Wang Chuanfu was going to reverse history. He was actually going to use lead-acid batteries to make electric cars. Even if these cars were made, they definitely wouldn't be able to sell.
"Chairman, listen to me. I know that iron-lithium batteries are the future, but lead-acid batteries still have their advantages. First of all, the cost is cheap. Although the energy density of lithium batteries is three times that of lead-acid batteries, the cost of lithium batteries is more than ten times that of lead-acid batteries. Even if they are larger, lead-acid batteries are still more cost-effective! "
[PS: This is the current cost. The cost of lithium batteries in the future will be at most three times higher.]
"Secondly, the stability and safety of lead-acid batteries are unparalleled. Also, our new generation of lead-acid batteries is ten times more stable than the old ones. I can guarantee you that even if there are a million electric scooters, in ten years, only two or three of them will spontaneously combust! "
"Also, we have the technology to control the speed of the battery's spontaneous combustion. This will ensure that the driver has enough time to escape from the car without any danger to his life!"
"Also, we can design an automatic fire extinguisher to extinguish the fire in the battery compartment."
"Lastly, the recyclability of lead-acid batteries is also better. We are currently developing a recycling technology for lead-acid batteries. We can recycle 70% of the raw materials in lead-acid batteries and use them to make new batteries. This will further reduce the cost of manufacturing and recycling the batteries. On the other hand, lithium batteries are very difficult to recycle after their lifespan is depleted. At least, that is the case with the current technology! "
"I don't want to hear any of your reasons!" Boss Jia shook his head. "I admit that all of these are advantages. But if the most important problem is not solved, all of these advantages are meaningless!"
"I know. The problem you are talking about is the charging problem of lead-acid batteries!" Wang Chuanfu nodded.
"That's right. Are you going to tell me that you, Wang Chuanfu, received a dream from Einstein? In your dream, he told you about the quick-charging method of lead-acid batteries, which can reduce the charging time to less than an hour?" Boss Jia said impatiently.
"Hehe, no, absolutely not. Even if I wanted to dream, I would dream of Tesla. Why would I dream of Einstein? He doesn't care about electricity!" Wang Chuanfu laughed. "And I know that it is very difficult to charge lead-acid batteries. Unless God changes the characteristics of lead-acid batteries, 20 hours is the limit of lead-acid batteries. Even if I live my whole life, I will never be able to break this limit!"
"Since you know this, you still … No, you brat, do you have other ideas to solve this problem?" Boss Jia was halfway through his sentence when he suddenly realized that he seemed to be speaking according to the script of those stubborn old men. Wang Chuanfu took the protagonist's script and was digging a hole for him to jump into!
But then again, if Wang Chuanfu really had a way to solve the charging problem, then lead-acid batteries would not be useless!
But the problem was, how would Wang Chuanfu solve the charging problem?
"Chairman, my idea is very simple. Since it is very difficult to break through the charging speed, then we might as well not study how to increase the charging speed. We don't even need to charge our electric scooters!" Wang Chuanfu said his idea loudly. "We don't need to charge, we need to change the batteries!!!"
