1 hour, 59 minutes and 40 seconds! On October 12, 2019, in Vienna, Austria, Kenyan long-distance runner Kipchoge completed an unprecedented feat and broke the 2-hour mark for a full marathon. He brought the human limit to an unprecedented height. Even a person like me, who is not good at running, was shocked by it. Challenging limits is the innate potential of human beings and drives the world forward. To put it bluntly, fighting against the sky, the earth, and yourself is endless fun. There are too many projects that humans can challenge, such as the ultimate range of pure electric vehicles, which can also be regarded as one. Electric vehicles have been fully rolled out in our country, and all qualities have been steadily improved. However, when it comes to electric vehicles, consumers are currently concerned about two words - battery life. On the one hand, it is the driving distance, and on the other hand, it is the ratio of actual performance to official data (authenticity). Anyone who does not value these two points when buying a car should not be considered a real user of electric vehicles. BYD is China's leader in new energy vehicles. Its electric vehicles have performed well in the market. The Dynasty series includes multiple models such as Qin, Tang, Song, and Yuan. Recently, BYD has launched the new Qin EV, which will be launched in Beijing on November 5. The high-endurance version of the luxury model and the premium model have pre-sale prices of 139,800 yuan and 146,800 yuan respectively. In order to verify the strength of a popular new household pure electric car before its launch, a battery life challenge was held as scheduled in Qilu. In the past, BYD Qin EV was the preferred model for 100,000-class household pure electric cars. Now, the new Qin EV is back on the scene. The new car is built on the BYD e platform, and the core three-electric technology has been upgraded again. It has a ternary lithium battery with an energy density of 160Wh/kg and a

In the past, BYD Qin EV was the preferred model for 100,000-class household pure electric cars. Now, the new Qin EV is back on the scene. The new car is built on the BYD e platform, and the core three-electric technology has been upgraded again. It has a ternary lithium battery with an energy density of 160Wh/kg and a total capacity of 53.1kWh, and an efficient integrated motor, electronic control and transmission. With more reasonable software control, it can achieve The battery life is 421km under NEDC operating conditions. The comprehensive range of 421km is the standard level of electric vehicles at this stage, and it can be used for urban commuting or short- and medium-distance travel. But many people want to know how far this car can go? Just like how fast a person can run, the challenge here is how far a car can run when driven by a person. Since it is an extreme endurance challenge, it will definitely be different from real-life cars. It will introduce extreme "unconventional operations", such as not turning on the air conditioner, driving at the lowest speed limit on the road, etc. It can be said that the power-saving skills of driving an electric car are brought into full play. . You see, the great master Kipchoge broke 2 in the marathon, wasn’t it a matter of teamwork, with a human wall to break the wind, and laser pace? The final score is for reference only. Let’s briefly review the process of BYD’s new Qin EV battery life challenge: around 8:10 in the morning, the vehicles set off from the Jinan hotel one by one. When fully charged, the driving computer showed a battery life of 421km, the subtotal mileage was cleared, and it was sealed with a seal. charging port. Use ECO mode throughout the entire journey and turn off the air conditioner. The energy recovery intensity is divided into two levels. Larger feedback is used in urban driving conditions, and standard feedback is used when driving on highways or national highways. Except for waiting for the red light, you basically don’t need to apply the brakes. In high-speed road conditions, under the premise of ensuring safety, the minimum speed limit is 60km/h when driving in the outside lane, and on national highways, the speed is about 50km/h. Comply with regulations and safety first. Including meals and rest, it took about 11 and a half hours. We arrived at Yantai Hotel at 19:39 in the evening, with a mileage of 500km, a remaining range of 54km, and a remaining battery of 13%. In the extreme state, BYD's new Qin EV has a range of more than 500km. Calculated based on the proportion of remaining power, it can travel about 575 kilometers completely empty. Some thoughts on the new Qin EV and battery life challenges: 1. By observing the average energy consumption of the last 50km on the driving computer, it can be seen that the new Qin EV saves most power when driving at a constant speed around 60km/h, and can be as low as 8-9kWh/h when the terrain is flat. 100 kilometers, and the speed exceeds 80km/h, it rises to 11-12kWh/100 kilometers. The faster the speed, the more electricity is consumed. It still holds true. Comprehensive consideration, it is not a big problem to achieve the official energy consumption of 12.9kWh per 100 kilometers in the ECO economic mode. This shows that the new Qin EV has higher three-electricity performance and a relatively solid battery life. 2. At medium and low speeds, the new Qin EV drives very smoothly, and the power response is slightly sluggish in the ECO economy mode. The feedback of energy recovery in both gears is relatively obvious, and there will be a certain pulling sensation when lifting the accelerator pedal. If a lower or non-recovery setting can be added to the first gear, it will be easier for the driver to control speed and energy consumption when running at high speeds. In addition, energy recovery adjustment can only be operated on the touch screen, which is slightly inconvenient without physical buttons. 3. The new DiLink 2.0 intelligent online dating system is powerful and easy to use. Anyone who knows how to use a smartphone can quickly adapt. The pre-installed Baidu navigation is very suitable for long-distance travel by electric vehicles. 4. On October 29, the test drive experienced ambient temperatures with a maximum of 24°C and a minimum of 6°C (on-board computer data). The battery life of the new Qin EV is quite strong at low temperatures, and the driving performance is guaranteed, but the energy consumption ratio is appropriate. The temperature should be higher. The actual optimal temperature is 15-20℃, which shows that the third-generation battery intelligent temperature control system works better than before. 5. The extreme battery life challenge data is for reference only, but the power saving experience can be shared: drive with a Buddhist mentality, keep the speed stable, and accelerate gently like stroking a pet; look far, predict in advance, and use as much energy as possible while ensuring safety Recycle and brake less. The extreme challenge of electric vehicle endurance is not only a test of vehicle performance, but also a test of human patience. The performance of the new Qin EV is satisfactory, and it also requires drivers to have a good attitude and rich experience.
