[car home Professional Evaluation] BYD Qin is an early player in the new energy market, and people are deeply impressed by it. Today, I will bring you a test drive of Qin EV, and some readers may be curious. Now, Qin Pro will be listed soon. Why do you still test Qin? Don’t worry, the Qin brought to you this time is an EV450 model with a ternary lithium-ion battery. What is its endurance performance? Let’s find out together.
After reading the following, you have read 70% of the full text:
1. The endurance under high-speed working conditions can meet the long-distance inter-city travel. Considering the current distribution of charging piles, it is recommended to drive 270km for a recharge. Driving at an average speed of 91km/h, after driving for 280.7km, the remaining cruising range is 62km and the remaining power is 15%.
2. The endurance of urban working conditions can meet the daily commuting needs. With the average speed of 29km/h, after driving for 200km, the remaining cruising range is 164km and the remaining power is 41%.
3, driving experience, abundant power, suspension adjustment tends to be comfortable.
4. In terms of exterior interior design and materials, the exterior interior has basically not changed, and the interior materials are good.
5. The performance of driving space is acceptable, but the space expansion needs to be improved.
Compared with the old Qin EV300 model, BYD Qin EV450 model’s main change is that the power battery has changed and the cruising range has been improved. Its changes in appearance and interior are not obvious, so today we go straight to the point and start with its endurance test.
○ High-speed battery life: basically, cross-city travel is barrier-free, and it is recommended to replenish power once at 270km.
High-speed working conditions always test the endurance of electric vehicles, because when driving at high speed, electric vehicles are in a state of high energy consumption, and the cruising range of comprehensive working conditions we usually see will be discounted here. As for how much discount we can make, it will vary from car to car. Car home tests the endurance of electric vehicles at high speed from full charge, with an average speed of about 90 2 km/h, until the remaining power is less than 15% or the subtotal mileage on the meter reaches 300km. The co-pilot will also have a person to take turns driving and be responsible for the whole record.
According to the actual measurement, after BYD Qin EV450 runs at an average speed of 91km/h for about 2 hours and 58 minutes, the battery power is only about 15%, the actual mileage is 280.7km, and the remaining battery life is 62km. The average remaining battery life consumed per 1km is 1.2km, so it can be concluded that the battery life of the car is about 332km under high-speed working conditions. Because the test is currently conducted in summer, which is more advantageous than the endurance in winter, there will be a certain discount in the performance of endurance driving in winter. However, such high-speed endurance can basically meet the inter-city traffic demand. If you travel long distances across provinces, as far as the current construction status of charging piles is concerned, it is recommended that you make a mid-way recharge every 270km.
○ Low-speed battery life: there will be no mileage anxiety when traveling in cities.
After testing the high-speed endurance, we then tested the low-speed endurance. In fact, most friends who buy or want to buy an electric car drive more in the city, so the cruising range under urban working conditions is more reference. In our low-speed endurance test, the average speed is set at 30 2 km/h until the remaining power is less than 15% or the subtotal mileage on the meter reaches 200km.
After testing, when the cold air conditioner is turned on all the way and the average speed is 29km/h, after the BYD Qin EV450 runs for 200km, the remaining cruising range is 164km, the battery power is 41%, and the average cruising range consumed per 1km is 1.18km. Therefore, it is concluded that the cruising range of the car is about 339km at low speed, which can be easily handled by daily commuting. If the daily commuting is about 60km,

Compared with the previous BYD Qin EV300 model, Qin EV450 is equipped with a ternary lithium-ion battery pack, and the power battery capacity is increased from 47.5kWh to 60.48kWh. In addition, although the motor power is the same as that of the 300 model, the acceleration level is good and the subjective feeling is still very fast.
○ Dynamic feeling: accelerating performance beyond expectations
I believe everyone knows the characteristics of the instantaneous maximum torque explosion of electric vehicles, but Qin EV450 will not give you a strong sense of pushing back at the beginning, on the contrary, it is very calm. I think it is appropriate to use the word "calm" to describe it, and the whole process will not give you an obvious sense of suddenness. However, after the speed exceeds 25km/h, the power output becomes very abundant and has a strong sense of pushing back, and you will not feel it until the speed reaches 90 km/h.
Qin EV450 has two gears of energy recovery for the driver to choose from, and the setting of recovery is relatively good, perhaps to avoid a bad ride experience for passengers. Even when the energy recovery is adjusted to the second gear, the dragging feeling is not abrupt and will not affect the ride comfort. If you adjust to the first gear for energy recovery, the feeling after releasing the accelerator pedal is basically similar to that of a fuel vehicle.
In ECO mode, in order to save energy and ensure a high cruising range, the dynamic response seems to be limited, not only the damping sense of the accelerator pedal is enhanced, but also the dynamic response seems to be limited. However, when the driving mode is SPORT, it has completely changed its personality, and the accelerator pedal is sensitive and the power output is more abundant.
Judging from the 150,000 pure electric vehicles tested by our EV AH-100 at present, it is quite good for Qin EV450 to run to a 0-100km/h acceleration level of more than 7 seconds, which is faster than the official claim of 7.9 seconds. Compared with the current models of the same class, it can be said that it is quite good.
EV AH-100 score in power part
zero Brake and noise test:
The adjustment of the suspension tends to be comfortable. Although it has a good filtering effect on small potholes on the road, the vehicle will still have an obvious roll when cornering quickly. When passing some higher speed bumps, the springback of the spring is a little delayed, so it would be better if the resilience of the spring can be improved.
The foot feel of the brake is good, the pedal force is moderate, and the braking force is relatively linear. However, due to the high body and large vibration reduction stroke, the wheel has a distance of one punch and three fingers from the wheel cover, and the vehicle still has obvious nodding phenomenon when braking suddenly.
More exciting videos are all on the car home video platform.
When the pile is wound, the sense of vehicle roll is obvious, and the steering feel of electronic power-assisted steering is very light. Fortunately, the accelerator pedal is very sensitive, and the continuity and explosiveness of power output are good.
During the braking test, the brake pedal strength is moderate, and there are few empty positions, and the performance is relatively balanced when braking continuously, which is quite excellent in the same class of vehicles, but the phenomenon that the vehicle leans forward when braking is still obvious.
After the actual measurement, the overall sound insulation of BYD Qin EV450 is good, and the noise value is lower than the recommended value in all kinds of conditions, especially at high speed, the tire noise suppression is not bad (which may be related to the Michelin Grand Hyatt tire), and at low speed, the obvious motor noise will not be heard, so the performance of NVH is still affirmed.

○ Review of exterior interior
For the appearance and interior, I won’t go into details here. I believe everyone is already very familiar with this style. The difference between it and Qin EV300 is only on the net, but the interior is exactly the same. Let’s briefly review it.
Although the appearance of Qin EV450 is not obvious, the changes in the details of China Net make it easy for people to distinguish between new and old models, and at the same time, it also enhances the overall sense of the front face and makes the car look more harmonious.
As for the interior, except the overall layout and style are the same as those of Qin EV300, Qin EV450 also inherits the quality of the old models in terms of the materials and details of the interior. The function buttons are not complicated, the operation is very simple, and the central big screen looks very convenient. In addition, although the car is equipped with multimedia voice control function, the response speed of the system is somewhat average in actual experience, and I hope to have a better performance in the future.
EV AH-100 score of static part:
zero The spatial performance is medium.
Because the body size has not changed compared with the old models, the performance in the interior space is the same as that of Qin EV300, which can only be said to belong to the same standard level. However, the soft seat padding and the good length cushion bring good comfort.
The experiencer with a height of 1.77 meters sits in the driver’s seat, and the height of the seat is adjusted to the lowest, and the front and back are adjusted to a suitable driving posture. The head space has 4 fingers, and the front row remains unchanged. The head space in the back row has 4 fingers, and the leg space performs well.
Compared with similar models, Qin EV’s performance in storage space is moderate, with only one cup holder in the center of the front row, and the central armrest box is average in depth, which can’t hold a bottle of 500ml mineral water, but the depth of the water cup slot on the door panel is good, and there is a water bottle limit mechanism, and a storage slot is also set on the back door panel.
Although the trunk is not regular, it can hold three suitcases of 20-inch, 24-inch and 28-inch. However, the rear seats cannot be laid down, which affects the flexibility of storage space.
Total score of BYD e5 450 EV AH-100:
Full text summary:
Although the novelty of appearance is not high, fortunately, the changes in details have not let everyone down. The interior texture is good, and it still inherits the quality of the old Qin. At the same time, the upgrade of power battery has further improved its battery life and improved its market competitiveness. On the whole, Qin EV is a model worthy of recommendation, but there is still room for improvement in driving texture and space flexibility. If there will be a significant progress in the next generation of models, it will be. (Text/Photo by car home Liu Liwei/Yao Jia Ji Zhenjia)
