Chapter 116 Battery High Temperature Speed ​​Limit?

At this time, on the track, Xia Keyuan's vehicle and Oudi's vehicle are making the final sprint.

The Oudi vehicles are in the front, and those of the Xia Keyuan are behind.

Based on the speed and distance between the two, the Oudi vehicle is far ahead.

Just when everyone thought that the overall situation was decided, the Audi vehicle would be the first to hit the line.

There are still two or three kilometers away from the finish line. For some reason, Oudi's vehicle is slowly slowing down.From the previous [-] kilometers per hour, it gradually slowed down, and it became slower and slower.In the end, compared to before, it became a turtle speed.

According to visual inspection, Oudi's car can only run at a speed of 20-30 kilometers per hour.

At this time, the vehicle of Xia Keyuan was still at a speed of 80. Under this speed difference, the distance between the two was quickly shortened.

Originally, the distance between the two was not very far. In just a moment, Xia Keyuan's vehicle passed Aodi's car.

And as time goes by, the distance between the two is getting farther and farther.

This.
Seeing this situation, everyone was stunned. They didn't know what happened to Oudi. At this critical moment, let the opponent go?
Could it be that Ou Di is lonely in seeking defeat and doesn't want to get this headache?

If you don’t want to be number one, you should have said it earlier, why do you have to release water at this time, isn’t it a bit inappropriate?

But it’s not right, the Oudi team was quite excited before.It can be seen that he is very concerned about the name of the first one to cross the line, and there is no reason to let it out like this.

That is to say, there was a problem with Oudi's vehicle, which caused the vehicle to slow down?
You should know that Oudi's vehicles use pure electric vehicles, and the monitoring of the status of the whole vehicle is quite strict.

The insulation status of the vehicle, the voltage and temperature information of the battery, the temperature of the motor controller, the speed of the motor, etc., and the network communication inside the vehicle.

And so on, the data must be judged in real time.

Only when all the data is normal, the vehicle can let go of the restrictions and drive freely.

Like Oudi vehicles, the slow-moving state at this moment is very consistent with the failure of the whole vehicle, which leads to the slow speed of the vehicle.

In fact, many new energy car owners often encounter such slow speed situations.

The most typical one is that the battery is dead, and it's useless no matter how much you gas the pedal. You can only move slowly at a speed of 20-30 yards.

In addition, in summer or winter, this situation is also prone to occur under extreme ambient temperatures.

The state of Oudi's vehicle is quite consistent.

But why this happens to the vehicle is unclear.

After all, you can't tell anything just from the outside. You need to see the vehicle's operating data.

In the base camp of Qinghai Lake, where the Oudi team is located, the technicians of Oudi were dumbfounded looking at the row of data marked in yellow on the monitor.

It is not good when the vehicle has problems, it has to be at this time.

Oudi technicians have determined that the battery temperature is too high, which leads to the protection of the whole vehicle and limits the power of the vehicle.

In the past, there may have been 150kW of power, but now, it is only less than 30kW.

At this power, the motor can only barely move the car, and it is impossible to want too high a speed.

Of course, the temperature state of the battery now only reaches the yellow value, and when it reaches the red value, the power of the battery will be limited to zero, and it will not be able to run at all.

It's just that how the temperature of the battery is so high, the technicians of Oudi are a little puzzled.

Before participating in the challenge, Oudi's technicians made a detailed assessment of the status of the vehicle.

Especially the battery, it is the focus of care.

In terms of battery life, because this time around Qinghai Lake, there is a distance of nearly 300 kilometers.

Considering the influence of temperature and road, Oudi technicians specially charged the battery fully before the game.

Even without wasting the vehicle's power from the place of residence to the competition venue, Ou Di generously brought a charging pile, and recharged it an hour before the competition.

The purpose of doing this is to ensure that the battery is fully charged and will not run out of power while running.

As for other manufacturers, there are no private charging piles, so they can only squeeze the public charging piles. The day before the competition, the vehicles are fully charged, and then put there for use the next day.

There is nothing wrong with Oudi's approach.After all, the whole journey is 300 kilometers, and the road conditions are complicated, especially with the highways, which consume a lot of energy. The cruising range of the vehicle is not too much.

Not to mention, in this competition, many manufacturers did not calculate the cruising range and underestimated the power consumption, resulting in the vehicle running out of power and breaking down on the road, which was also embarrassing.

Oudi's deep pockets ensure that the cruising range of the vehicle is not a problem.

However, Oudi never thought that temporary high-rate charging would cause a sharp increase in battery problems.

After it is fully charged, it will soon start racing and discharge at a large rate.

The temperature of the battery rises even faster.

Coupled with this competition, it has the meaning of racing.

Oudi's vehicle has not yet reached the end, the temperature of the battery has been marked yellow across the board, and it cannot be discharged at full power.

After reaching this conclusion, the Oudi team members were dumbfounded.

This is a little too much to accept.

Is it possible that the battery temperature cannot drop due to high-speed charging in the morning, causing the battery to overheat?
Other manufacturers charge the battery one day in advance, cool the battery overnight, and then the battery temperature is about the same as the ambient temperature?

Good guy, it is estimated that there is a difference of a few degrees in the middle.

In this way, Oudi's vehicle, because of the battery temperature limit problem, fell behind the team of Xiake Academy, and hit the line as No.2.

Although No. 2 is also good, Aodi's technical staff are very unwilling to accept it.

After the Oudi team announced the reason for the vehicle's deceleration, people in the industry were also a little speechless.

I didn't expect this to be the case.

Some netizens ridiculed that this is the reason why I don't buy Oudi!

Some netizens said that this is the flaw of traditional lithium batteries, and they should always worry about the battery life of the vehicle.Audi did this just in case. Who would have thought that it was a bit too strong.

Some netizens said that this is the fate of not using carbon-based batteries.

If you use a carbon-based battery, charge it once every six months.

Even if you drive from Kyoto, there is no problem without charging.There is no need to waste so much time for excess power.

It was a bit funny for Jiang Ming to see that the vehicle of Xia Keyuan won the first place in the line in this way.

Such a serious game turned into a bit of drama in the end, which no one expected.

But no matter what, the Qinghai Lake Challenge is finally over.

Regardless of the results of the competition, many manufacturers have realized the future development and discovery of the automatic driving system through this challenge.

Through this challenge, I also realized the shortcomings of my own driving system.

Moreover, some manufacturers have gained greater cooperation opportunities by building relationships with other car manufacturers and parts manufacturers.

Among them, Siris' harvest is quite large.

Thanks to the outstanding performance of Xiake Academy, the Siris model has also received great publicity.

Mr. Zhang of Siris is also very satisfied with this.

Mr. Zhang wanted to meet Jiang Ming again many times to thank Jiang Ming, but at this time the team of Xia Ke Academy was located and it was really not possible to squeeze in.

As expected, Xia Keyuan relied on its outstanding performance and the bonus of the honor of being the first to cross the line.In the end, it won the championship of the Qinghai Lake Intelligent Driving Challenge.

As for Oudi, he won the runner-up.

The rest are barrels, Boshi, Benchi and other international manufacturers.

In the top ten, except for the head ditch of Xia Keyuan, it is the future team.

As for Xiaopeng, Weima, Dongfeng and other automakers, they are all outside the top ten.

The outstanding performance of Xia Ke Institute has amazed the entire automobile industry.

Especially knowing that the team of Xiake Academy does not produce vehicles, but focuses on the automatic driving system, there are many car manufacturers, which is a bright spot.

To say that the automatic driving system is the direction of the future, this is known to any company engaged in new energy.

But knowing what you know, it is not easy to develop an automatic driving system and achieve good results.

The technology and funds that need to be invested in the middle are not affordable for ordinary enterprises.

Based on this, it would be best if you can directly buy the system of a mature third-party company.

Of course, this is based on the limited research and development capabilities of our own.

In fact, these companies hope that the autonomous driving system can be like a computer operating system.

Although the bottom layer belongs to others, it has also developed a lot of targeted applications to jointly develop this autonomous driving ecology.

The independent attribute of Xia Ke Academy is naturally suitable for doing this kind of thing.

It's just that the team of Xia Ke Academy is too busy at this time, and there are too many people to receive.

Seeing this, Qin Ruya simply didn't see anyone.Instead, he sent out his contact information and address, and will deal with this matter after returning to Kyoto.

The Qinghai Lake Autonomous Driving System Challenge has come to a successful conclusion.

After the competition ended, the inside story about the challenge also spread.

The problem that the Tesla can't stop the car was discovered and confirmed by Professor Jiang from the Xia Ke Academy.If you want to ask who Professor Jiang is, he is the one who studies carbon-based batteries.

The navigation of any vehicle in the mysterious valley fails.In the end, it was Professor Jiang who turned the tide and gave a solution.

Jiang Ming's team finally overwhelmed Oudi Vehicles and won the No.1 result.

Charcot is worthy of being a pioneer in the driving industry.

All kinds of news came one after another, making people overwhelmed.

Suddenly, the topic of autonomous driving lasted for a long time on the Internet.

With the help of autonomous driving, the stock prices of many listed companies took off directly.

After the challenge, many car companies all went to the Xia Ke Academy in Kyoto to cooperate in the joint development of autonomous driving.

Jiang Ming had no opinion on the issue of joint development.

Originally, the development of the automatic driving system was to allow it to be applied on a larger scale.

Moreover, the driving system designed this time, from hardware to software architecture, is completely prepared for mass production.

And in order to reduce costs, Jiang Ming selected components that are relatively cheap and popular.

In the whole car, the only high-end one is the main controller.

This ultimate design will minimize the cost of the autonomous driving system.

Moreover, the portability of the driving system is also very good. This issue was taken into consideration at the beginning of the design.Migration can be performed with only a few changes.

Based on the promotion of the automatic driving system, Xia Ke Academy did not have any embarrassment, but promoted the driving system at a relatively low cost.

The entire software system, the price of each car, is only [-] yuan licensing fee, which can be said to be quite affordable.

The promotion of the automatic driving system does not need to worry about Jiang Ming, Jiang Ming has a very important thing now.

After the challenge ended, Jiang Ming received a notice from Wang Mingyang, asking Jiang Ming to come to Kyoto to receive the award.

Jiang Ming was stunned for a while, not knowing what award he was going to receive.

After Wang Mingyang explained, Jiang Ming remembered that Mr. Long promised to give him a National Science and Technology Progress Award before. If Mr. Wang hadn't reminded him, he would have forgotten it.

The National Science and Technology Progress Award is generated from nominations, and Jiang Ming's project is honored to be selected.

Because this time it was a national award, Wang Mingyang specifically told Jiang Ming to dress up well and be more formal.

In fact, without Wang Mingyang saying it, Jiang Ming also knew the seriousness of the national awards.

You must know that the National Science and Technology Progress Award will be held in the Great Hall, and the awards will be presented by important leaders of the Xia Kingdom.

The meaning of this honor, don't think about it, is also very important.

It can be said that receiving this kind of national award will give you great satisfaction in terms of project funds, equipment and personnel.

Of course, these national awards have extremely high requirements for the winners.

It is impossible to win awards unless you have made outstanding contributions to the industry and achieved groundbreaking achievements.

It is precisely because of this seriousness that each winner will be greatly respected.

When he was young, Jiang Ming always watched the scientists on the stage on TV, and imagined in his heart that he would become one of them in the future.

After growing up, Jiang Ming knew that the chance of becoming one of them was too slim, and the thoughts in his heart gradually weakened.

Now that the dream of a scientist can be realized, Jiang Ming feels excited just thinking about it.

This kind of excitement is the recognition of honor, the affirmation of contribution, and the country's gratitude to the individual on behalf of all the people.

This kind of award was too grand, and the grandness made Jiang Ming a little dazed.

Clutching the trophy in his hand and the certificate of honor representing his achievements, Jiang Ming's thoughts flowed in his mind. As a native of Xia, he died as the soul of Xia. This collective sense of honor and the cohesion of this era are really good.

Jiang Ming was thinking, this is also the reason why Xia Guo selects advanced science winners for public recognition every few years.

In this way, it was announced to everyone that Xia Guo paid enough attention to outstanding scientists.Xia Guo will give full respect to those who have made outstanding contributions!
