"The catalyst is not that short, in fact, years later." Liu Dacheng replied vaguely.

It would be better if there were other questions that came up now, and he could get past them without answering.

"A couple of years is a few years? Is it two years or four years or five years? Gu Yu pursued this issue closely.

"I think over time we will be able to develop better alternatives to catalysts. Costs can be significantly reduced. Liu Dacheng glanced at Gu Yu at this time, before he thought that this little girl was not his opponent at all, but now the question she asked was very fatal to him.

"As far as I know, the limit of the use of the catalyst for your current battery is 2 years, and if you want to replace the catalyst, the cost is equivalent to three-tenths of the price of the car, do you think the user can afford it?" Gu Yu pointed it out directly.

Mu Rongheng told himself that Liu Dacheng's battery has major flaws, one of which is the cost of the catalyst.

The two-year time limit has shocked the judges with the price of follow-up maintenance. They sternly asked Liu Dacheng: "How long is the life of the catalyst?" What is the price of replacement? Please be specific. ”

"This ......," Liu Dacheng thought about how to avoid this issue from being further investigated, and explained with a humble and sincere attitude, "It's really been two years now, but I'm improving." I believe that within two years, I can find a better replacement. ”

"Mr. Liu, it seems that your after-sales service is still undetermined, let me ask you another question, how do you know that your battery has been filled after it has been filled?"

"Isn't that simple? The indicator light will flash from red to solid green. ”

"So what if the charger forgets to unplug the power supply after the charge is charged?"

"This is the same as charging a mobile phone, you must do the necessary charging management yourself."

"Your battery is an H fuel cell, which will heat up if it is charged for too long, and H fuel is a very explosive gas, which is very unsafe in high temperatures, and you can't guarantee the safety of those people in Madahar, right?" Gu Yu raised the second major defect in his battery.

"Isn't your battery overcharging and not heating up?" Liu Dacheng asked unhappily.

What he stole was Mu Rongheng's technical achievements, and it had exhausted his energy to understand it thoroughly and make it into a battery to make money, where would he have the spare energy to improve it? And I don't have such advanced technology to improve.

"Of course." Gu Yu replied.

"What method do you use?"

"I'll introduce it when it's time for me to explain."

After such a question, everyone in the audience had a very bad impression of Liu Dacheng's battery, and was more interested in Gu Yu's battery, and asked her to explain it immediately.

Gu Yu spoke eloquently, easy to understand, and convincing.

She emphasized that her catalyst was switched to low-cost silver, and the follow-up maintenance and repair would not pay too much cost, and said that she designed a battery charging and power-off protection chip to ensure that the battery will not catch fire due to overcharging.

And it has a longer range and a shorter charging time, after her comparison, her battery is compared with the battery designed by Liu Dacheng, which is simply one in the sky and one on the ground.

"Just blow it. What I have learned, the developer who helped you design this battery has withdrawn, if your battery is good, it is also because the developer's technology is good, but he no longer continues to serve you Michael, how do you ensure that your battery can continue to develop in the future, if you encounter technical problems, who will solve them? Liu Dacheng pointed it out mercilessly.

"It's true that my technology developer has withdrawn from the partnership, but he's not really leaving, he's turned to our technical advisor, and he's going to train my technicians on an ongoing basis. We ourselves are our own battery developers, rather than relying on independent external developers, which can better ensure the sustainability of our battery development. Gu Yu smiled and said, "As the head of the battery department, I will never leave my company for the rest of my life, and I also believe that my technical team can provide good services for everyone." ”

"Bragging rights, can you guarantee that you won't leave for the rest of your life? Job hopping abounds, and it's hard to guarantee that employees will always be working for the same company. Liu Dacheng said sarcastically.
