Super Copy of Great Power Technology

In the second hour, one test car ran out of power and exited the test. It was the basic version of MINIEV.

"Now that the test has started for an hour and 38 minutes, we can see that the MINIEV basic version test car has run out of power and completed the test. Its final cruising range is 125 kilometers, and its NETC cruising range is 200 kilometers. The cruising range has reached The rate is 62.5%. It can be seen that the ultra-low temperature environment of minus 7 degrees has a great impact on the battery life of electric vehicles. This MINIEV basic version is not equipped with a fast charging interface, only a normal charging interface. Charging using a 3.5KW slow charging pile or a KW portable charging pile takes a very long time. We rolled the test car out on the oval track and used a generator car to slowly recharge it.”

In the second hour, another test car ran out of power and exited the test. It was an improved version of MINIEV.

"Two hours and 2 minutes after the test started, the MINIEV improved version test car ran out of power and completed the test. Its final cruising range was 31 kilometers, its NETC cruising range was 192 kilometers, and the endurance achievement rate was 300%. Endurance reached The number of trips has increased, and the specific reasons will be analyzed later. Starting from the MINIEV improved version test car, the following cars are equipped with fast charging functions and can be connected to fast charging piles for quick charging. For the convenience of comparison, we will not do this now. Charge it, and after the top-of-the-line MINIEV completes testing, we will charge the two vehicles at the same time.”

Not long after the third hour started, the last MINIEV test car also ran out of power and exited the test.
"Three hours and 3 minutes after the start of the test, the MINIEV top-end version test car completed the test. Its final cruising range was 24 kilometers, its NETC cruising range was 269 kilometers, and the endurance achievement rate was 400%. It can be seen that the MINIEV three From low to high models, the battery life achievement rate is constantly improving. This is related to their battery size and the working principle of the vehicle air conditioner. When the electric vehicle is cold started, it will automatically detect the outside temperature. If it is particularly low, it will start the battery heating process, first raising the temperature of the battery. This process of raising the temperature will consume additional power. At the same time, in a relatively low temperature environment, if the vehicle air conditioner is turned on, the system will Electric energy is used to heat the air to raise the temperature inside the car in the shortest time. This will also consume some additional electric energy. In the three different versions of the MINIEV test car, because the models are the same, the interior spaces are the same. The power consumed in advance is roughly the same, but the impact of this part of energy consumption on the overall battery life is completely different. The smaller the battery, the greater the impact, and the larger the battery, the smaller the impact. This is also true from the basic model, to the upgraded model, to the top model. The reason why allocation and battery life achievement rates are increasing sequentially.”

"The remaining two sports cars are still running lap tests. Their NETC cruising ranges are both 1000 kilometers. It's still early for them to finish testing. Let's first conduct a charging test of the two MINIEVs. Come with a few people to lend a hand and charge these cars. The two test vehicles were pushed next to the generator car. We used the electric vehicle super fast charging station developed by Ruida Automobile. Its fastest charging speed is 100KW, and the super fast charging station is powered by a large diesel generator. , the maximum power supply is 500KW, which is more than enough for two super fast charging stations. On the display screen of the super fast charging station, information such as connection mode, real-time charging power, power consumption, and charging time can be displayed. Insert the charging gun into the fast charging interface of the two MINIEVs. OK, the green indicator light will light up at the same time, charging starts, and you can see the real-time charging power displayed on the two super fast charging stations, both of which have a rapid ramping process. , it took about twenty seconds, and then entered the stable charging stage. The real-time charging power displayed by the charging pile was stable at around 25KW and 30KW, and the charging speed of the top-end MINIEV was slightly faster.”

"The charging curves of the two MINIEVs are very similar. In the first half of the charging process, the charging power is very stable, always fluctuating around 25KW and 30KW. Until the electric energy is replenished to more than 80%, the charging power quickly drops to more than ten KW, which is stable for a period of time. time, the electric energy is replenished to more than 90%, and the charging power is reduced to about 8KW again until the electric energy is fully replenished. The charging time of the two MINIEVs is also about 45 minutes. If you are pressed for time and are in a hurry, you can fully charge it. After 80%, draw your gun and leave, because the replenishment speed of the last 20% of the power is very slow, taking about 20 minutes.

As for the MINIEV basic version next to it, it is still charging slowly. The real-time charging power is only about 7KW. It has been more than an hour and the electric energy has just been replenished to about 50%. The name of slow charging is worthy of its name. "

At this point in the test, it was already close to noon, and members of the logistics team began to prepare lunch for the team members. The smell of food continued to drift from the direction of the RV. The remaining two Roadster sports cars were still racing on the runway. The drivers and passengers in each car were very tired. Qiao Ruida took out the walkie-talkie and communicated with the drivers of the two sports cars, asking them to stop the cars temporarily. Then she called eight people to replace their positions and continue the second half of the endurance test. As the old saying goes, life lies in movement. Human beings can only ensure health through continuous exercise. Standing for a long time or sitting in a car for a long time can make people tired. If you are in the driver's position and need to concentrate all the time while driving, you will be more likely to get tired. For example, the battery life test of electric vehicles takes a long time. It is a routine operation for drivers to take turns to rest or simply replace the entire vehicle.

As the time is approaching noon, the number of people online in the live broadcast room has also decreased. At this time, there are only about 500 million, but the barrages and messages are still densely packed and have not decreased.

"The cruising range of this basic MINIEV car is too short. It is 125 kilometers. It ran out of power just after it ran out of the city. This range is not enough for anything except commuting to work or picking up and dropping off the children. "

"Indeed, the range achievement rates of these three MINIEV cars are somewhat low, below 70%, which is a serious false standard."

"The virtual standard is not that good. You must know that this endurance test was conducted at minus 20 degrees, with four people fully loaded, air conditioning on, cruise control at 80 kilometers per hour, driving mode sport, and kinetic energy recovery turned off. Even with such negative debuffs, it is still possible to achieve more than 90% of the cruising range. Ruida Automobile is very honest in marking the cruising range if it is in normal temperatures in spring, commuting in the city, and shutting down. With air conditioning, it is very possible for the cruising range to reach more than 100% or even % of the nominal value when there is only one driver.”

"If you buy a MINIEV, charging will be a problem. There are too few public charging piles in our city."

"If you have a garage and home charging pile at home, buying a MINIEV for urban commuting will be very comfortable and the cost of using the car will be very, very low."

"In fact, MINIEV is the most suitable car for the elderly to buy. It is not expensive, easy to maintain, and has low cost of use."

"If new energy vehicles want to be promoted on a large scale, the construction of charging piles cannot be delayed. Otherwise, replacing fuel vehicles with new energy vehicles can only be empty talk."

"It makes sense. Compared with traditional fuel vehicles, the biggest disadvantage of electric vehicles is that it is too inconvenient to recharge. If a fuel vehicle is out of fuel, you can go directly to the gas station and fill it up in minutes. The charging speed of electric vehicles is too slow. , it only takes an hour or two, and public charging piles are still a rarity nowadays, and there are not many in a city. ""If there are fast charging piles, the charging speed of this MINIEV is also acceptable, about 30 minutes. It’s time to have a meal.”

"In comparison, the Roadster sports car has a longer battery life. It has been running for many laps and it is still moving forward."

"The cruising range of these two Roadster sports cars is 1000 kilometers. Even with a 600% discount, the range is still kilometers. They have just run more than kilometers now, and it is still early to end the test."

"You get what you pay for. The basic version of the Roadster sports car costs millions. Naturally, no effort has been spared in building hardware. If it weren't for the fact that the chassis space of the sports car is really limited and cannot accommodate too many lithium batteries, the battery life will be very low. It is not impossible to increase the mileage to more than 1500 kilometers. "

"The two new cars of Ruida Automobile use ternary lithium batteries. I heard that these batteries can catch fire and explode due to short circuit. Their safety is questionable. It is better for everyone to buy with caution."

"You are just overgeneralizing. If it is a soft-packed ternary lithium battery, a short circuit will indeed cause a fire, and the safety is not good. But the ternary lithium batteries used in cars are all 18650 cylindrical batteries or blade batteries. Both batteries have many safety measures. Even if they are short-circuited, they will only emit smoke and will not catch fire. When combined with sophisticated battery protection boards and temperature sensors, driving safety can be ensured to the greatest extent. In contrast, those used by fuel vehicles. The fuel is gasoline or diesel, both of which are flammable and explosive. If there is an accident, it’s hard to say which one is safer, a fuel vehicle or an electric vehicle.”

"Since electric cars can pass the crash test and obtain 3C certification, their safety is still guaranteed. If you buy an electric car, as long as you drive carefully, charge it normally, and don't cause an accident, you don't have to worry about safety issues."

Lunch was quickly prepared, and Qiao Ruida greeted everyone and took turns entering the RV to have lunch. On the oval track, the endurance test continued, and the two Roadster sports cars were still running at high speed. Since testing is still ongoing, the live broadcast room has not been closed. Fu Xiaoyi fixed the camera on a tripod and left one staff member behind while everyone else went to eat. For today’s lunch, several Northeastern dishes were prepared, including pork stewed vermicelli, pot-roasted pork, ground three delicacies, and so on. They were rich in flavor, nutritious, and tasted good. Qiao Ruida and the team members were very happy to eat.

Half an hour later, all the team members had finished their lunch, including the eight team members in the test car, who were replaced by others and went to have lunch. According to Qiao Ruida's estimation, the Roadster sports car's battery life achievement rate is about 70%, and the entire battery life test process will take at least eight hours. Just over four hours had passed, and it was still early. Qiao Ruida and Du Qingqing simply went to the RV to take a nap. As for the live broadcast room, it was temporarily handed over to Fu Xiaoyi and the live broadcast team.

Lying on the double bed of the Mercedes-Benz RV, Qiao Ruida hugged her girlfriend and said thoughtful words, "Qingqing, tomorrow's new car test will involve driving around the city of Mohe. It's not interesting, so we won't go. Mohe is a good place. There are many natural and cultural attractions to see, shall we go traveling tomorrow?”

Du Qingqing slapped her boyfriend's mischievous hand down and said, "Okay, okay. Along the way, I've been either rushing, racing, or testing cars. It's been so boring. Tomorrow I'm going to Arctic Village, Arctic Island, and Mohe. Guanyin Mountain, I want to take a bunch of beautiful photos and share them on WeChat Moments so that my classmates and best friends can be envious.”

"Qingqing, thank you for your hard work. I originally promised to take you on a trip, but I have been busy with work and live broadcasts along the way. I have decided to leave the remaining test items to other members of the team. In the next few days , let’s drive around the scenic spots near Mohe to fulfill your little wish of traveling, taking photos, and showing off.” Qiao Ruida tightened her arms around her girlfriend and said rather guiltily.

This time Du Qingqing took leave from school and went north with Qiao Ruida. Originally, he came here for traveling, but he never expected to stay in the car all the way and act as a temporary guide. I only visited two or three scenic spots along the way and didn't take many photos. I thought that this trip to Mohe would be spent busy. Unexpectedly, her boyfriend found out that he had lost his way and said that he would put down work in the next few days and concentrate on traveling with her. This is really good news. In excitement, Du Qingqing turned around, kissed her boyfriend on the lips, and said: "Ruida, what you said is true, are we really going to travel tomorrow? In the live broadcast room Without you as the richest man, my popularity will drop a lot, are you really willing to do it? "

Qiao Ruida pondered for a moment and said: "This time we went north to Mohe to test a new car. The reason why we live broadcast the whole process is to promote the new car and warm up for the launch. It has been live broadcast for several days since the day we set off. The purpose of promoting the new car has been achieved. Even if I am missing from the live broadcast in the next few days and the number of people online is smaller, it does not matter. This time we are traveling together, and we are visiting Mohe, the northernmost city in China. It’s rare. If you don’t go out for a trip and take some photos, you always feel that your trip is in vain.”

Qiao Ruida hugged her girlfriend and had a good sleep. When she woke up, it was already four o'clock in the afternoon. I went to the bathroom to wash my face, opened the car door and went out to take a look. The endurance test of the two Roadster sports cars was still not over. Qiao Ruida waved, called Fu Xiaoyi over, and asked: "How many kilometers have these two Roadster sports cars run, and why is it not over yet?" (End of this chapter)
