Great Power Technology: Domination Of The World Starts With Chips

Biati's new car launch event had already started on August 30th, and it attracted the attention of countless people who wanted to buy a car.

The relevant car reviewers have also obtained the evaluation car.

Brother Hu is a well-known person in the car critic circle.

He participated in Biati's new car conference, borrowed a brand new car, and conducted a test.

The evaluation took a lot of time, and finally, he released his evaluation video.

"Big guy, I'm Brother Hu. I was lucky. I got Biati's new car, Biatihan EVSPROPLUS, which is the highest endurance car equipped with a power supply of 837 kWh."

"Let me complain about the name, is Biati stacking buffs?"

"Of course, this name also represents this pure electric vehicle, which is very strong! OH, SO, PRO."

"Not much nonsense, how strong is the battery life, let's test it!"

"As for the appearance and interior, let's test its battery life first!"

Brother Hu got into the car, pointed to the remaining battery, and said, "Look first, our remaining battery is now 70%."

"The cruising range of this car is 7,700 to 8,000 kilometers, with 70% of the electricity, which means that the cruising range should be about 5,600 kilometers. Of course, there is a little error, but as long as it can run 5,000 kilometers, even if it No misrepresentation of the car, okay!"

"Okay, don't talk nonsense, let's go straight away!"

"Of course, let me say something in advance. It is definitely impossible for me to drive 5,000 kilometers alone. So, this task will be completed by me, Ah Wei, and our photographer Jie Ge."

Then, Brother Hu got into the car with his assistant and photographer and started running.

The bullet screen was brushed up.

"Brother Tiger, you are going to fight hard"

"Three people drive alternately, and that one person has to drive more than 1,700 kilometers. Brother Hu is awesome, and he will deliver it three times in a row."

"Beware of tired driving"

"It's a reward, it's a reward. 』

"Don't talk about it, Brother Hu was a live broadcaster at the beginning. He ran more than a thousand kilometers a day and drove it for five days. Don't talk about it, just be awesome. 』

"I admire you. 』

"This lithium-air battery is too useless. I'm afraid everyone who does evaluations will have to test it like this in the future. The same is true for the Huawei S next door. It has been tested for more than 30 hours. 』

"I feel that it may be a waste of these machines specially used for evaluation. 』

...

As the evaluation begins, Brother Hu is still in the mood to chat with everyone.

"Our Biati, which has the longest battery life, can last 8,000 kilometers. If you choose horsepower, there is a model with stronger configuration, that is, the SPROPLUS+ model, which has a battery life of about 7,000 kilometers. Anyway, it is impossible to run more in China. quick.

"And even the one with the lowest battery life, that is, the EVSPRO model, has a battery life of 5,000 kilometers."

"We still have to say that lithium-air batteries are awesome."

"The original Biatihan used a lithium iron phosphate battery with a maximum capacity of 77 kWh, while our new Biatihan has a capacity of 837 kWh, which is directly an order of magnitude higher."

"Someone must ask, with such a large capacity, it must take a long time to charge, right?"

"That's for sure. Charging will definitely take longer than the previous electric car, but you can rest assured that the maximum charging power of this new car is also very high, because lithium-air batteries are very safe, and spontaneous combustion is basically impossible unless you directly Put it on the fire."

"In addition, when it comes to its power, we must talk about its charging." Brother Hu said: "Let me do the math for you."

"One kilowatt-hour is equivalent to one kilowatt-hour of electricity, that is to say, the original 77 kilowatt-hours of electricity is equal to 77 kilowatt-hours of electricity. Of course, when charging, the loss caused by resistance must be included, so it may actually cost more than ninety kilowatt-hours. Generally speaking, if you use fast charging, it can be fully charged in about an hour."

"And this 837 kilowatt-hours, that is, 837 kilowatt-hours of electricity, if it is to be fully charged, plus the loss, it may cost 1,000 kilowatt-hours of electricity. According to the current average price of electricity, 60 cents per kilowatt-hour is equivalent to a full charge. It costs 600 yuan.

"Compared with our gasoline vehicles, let's compare it with cars. The fuel tank of most vehicles is 60L. If you add No. 92 gasoline, it costs 7 yuan per liter, and it costs 420 yuan to fill it up. From this point of view, it will cost us The cost of charging this brand new Biati is actually more than the price of gasoline.”

"Of course, that's not how it works. You spend 600 yuan, which is more than 100 times more expensive. The battery life is several times or even ten times that of a tank of gas. Which one would you choose? Anyway, I will definitely choose this one. I never I planned to buy an electric car last year, I originally wanted to buy a modely, but now, I basically decided on this model.”

"At that time, I can talk to my friend Versailles and say: 'Hey, I pay more for a charge than you spend for a gas refill'. My friend probably has to worry about me."

"Hahahaha" was written in the barrage

Brother Hu continued: "In addition, what I want to say is that according to Biati's official explanation, they ran in Heihe for a few days to conduct low-temperature tests. When the lithium-air battery is at low temperature, the battery capacity will not be as high as Lithium-ion batteries in the past have also been greatly affected, even at minus 20 degrees, the battery life and conductivity will not be too bad."

"So I asked a friend of mine who studies chemistry, what is the principle, and he explained to me that the electrolyte in Zhiqi's lithium-air battery is a solid electrolyte, while the battery used before is said to be more Yadi Blade Battery's Lithium Iron Lithium Batteries, they are liquid electrolytes."

"Friends who have studied chemistry should know that the lower the temperature, the lower the activity of those chemical substances, and the ion conduction speed in that liquid electrolyte is very slow."

"But Zhiqi's solid electrolyte is different. Even at low temperature, you don't have to worry about these problems."

"And there is no need to worry about the impact of low temperature on battery life. I don't know if you know that low temperature will cause irreversible damage to lithium-ion batteries."

"Fuck, is it true? 』

"My home is in the Northeast, no wonder my battery is not durable, the battery of my southern friend is much more durable"

"It is true that charging and discharging at low temperature will cause the capacity of lithium-ion batteries to drop"

"Brother Hu, stop reading, I'm going to bed, why are you talking about chemistry again?"

"How long has it been since I took chemistry class?"

"Holy shit, just to say that to Brother Hu, I decided to buy it too. I'm in the Northeast, and I need this kind of car that's not afraid of low temperatures. 』

...

The barrage was posted again, no matter whether you could understand it or not, it was still dry goods, and invisibly, it raised the impression of lithium-air batteries in everyone's minds.

Next, Brother Hu continued to chat with everyone while driving, and when he reached a place that was not the point, he accelerated and skipped.

So, he and his assistant photographer drove five days abruptly like this.
