As a new energy model electric vehicle has many advantages, such as subsidies, no lottery, low price, fuel saving, etc., but in the winter, due to battery problems, the hearts of many electric vehicle owners are also cool, charging endurance is short, low temperature charging is slow, charging piles are less, etc. In this winter, electric vehicle owners are more difficult to survive, especially the mileage problem.
We all know that the temperature in winter is too low for electric vehicle endurance has a very obvious impact, the reason is that, first of all, the efficiency of lithium batteries at low temperatures will decline, such as our mobile phones in the winter will also be more power-consuming, if you have been to the northeast of winter has a very intuitive feeling; Second, the electric vehicle in the low temperature, whether to maintain the temperature in the car, or the temperature of the battery needs to be heated by the electric heating device, which will also consume some power, affecting the endurance, in addition, the winter wind resistance coefficient will also increase. This makes the electric model look less beautiful in winter.
But are there any exceptions? Recently, we came to the northeast city of Shenyang, followed the first model of the BYD Ocean series - Dolphin, came to a big challenge of winter endurance, to see if dolphins can swim in the cold northeast.
The BYD Dolphin in this test has a total of 4 models on sale. The official guidance price is: 93,800-121,800 yuan. The actual model we chose, the fashion version of Dolphin.
The reason why the test site chose Shenyang, first of all, it is located in the northeast region of China, although it is not the coldest day of the year now, but the temperature during this period has been cold to the maximum temperature during the day is only 5 to 6 ° C, and the night temperature reaches about minus 10 ° C. This temperature basically represents the coldest weather in most of the winter in northern China, so it is more representative.
The test drive route starts from the Hilton Shenyang Shimao Hotel, around the second ring road, the fourth ring road, Danfu highway driving 2.5 laps, the whole 280 kilometers, covering congested road sections, urban expressways, highways and other almost full-scene road sections, lasted 8 hours, almost no rest, a little half-way Le Mans feeling.
Before the test, the vehicle was fully charged, the driving mode was adjusted to ECO mode, and the maximum feedback system was turned on.
In order to verify the normal driving environment, the air conditioner also chose to open normally, the temperature was set to 24 degrees, and it was adjusted to automatic mode.
Usually when the energy recovery is adjusted to the maximum, it will affect the driving experience, especially when the electric door pedal is released, the drag feeling transmitted by the recovery system can be clearly felt, but in the actual driving, although the BYD dolphin drag feeling will also be obvious, it is not stiff, and it almost does not affect the comfort of the driver, which is worth affirming.
Thanks to the Die platform 3.0 pure electric exclusive platform, SO THAT DOLPHIN has a breakthrough in the fuel model body structure and proportions, A-pillar forward, visual center of gravity moved backward, creating a low posture of lying motion, full and smooth appearance, more in line with the aerodynamic design, so its wind resistance coefficient (Cd) is as low as 0.21, so that the quietness of the car is more prominent, the urban road section driving only slight road noise and tire noise into the car.
In addition to the comfort of driving and the comfort of driving and the comfort of the ride brought by the stability and tranquility of the ride, its suspension tuning is also comfortable enough, and the BYD Dolphin adopts the front McPherson rear torque beam type, whether it is a deceleration or a fine bump, the treatment is relatively in place, and the over-bending stability and support performance can also be remarkable. At the same time, the steering feel is also relatively light, and the accuracy of the pointing is also good, which is very friendly to female users.
In the up to nearly 8 hours of driving, a powerful and fun car machine system, undoubtedly for this part of the journey to add some fun, BYD Dolphin using BYD D-Link system, its Android car machine in the function is almost the same as the mobile phone, which WeChat, vibrato and other applications are directly used mobile phone version, even in the car machine to play the king, eat chicken is not a problem, while this set of screens can also be rotated between the horizontal screen and the vertical screen, the speech recognition rate is also at the same level of leading level.
It is worth mentioning that the BYD Dolphin gear lever, together with the air conditioning control area, AUTO HOLD, electronic handbrake, ESP and other operating buttons, adopts a knob type, and is designed into an innovative roller design, which is visually very metallic. The operation is very smooth and more conducive to blind exercise.
In terms of power, the fashion version of the test drive adopts a front-mounted single motor, the maximum power of the motor is 70kW, 95 horsepower, the maximum torque is 180N·m, the official acceleration of 100 kilometers is 10.9s, and the battery still uses BYD's blade battery, with a capacity of 44.9kWh and a pure electric mileage of 405km. This set of power tuning is more oriented to the public, the power output is linear, comfortable, but the acceleration response is very sensitive, whether it is urban driving or high speed, the overtaking action is completed with vigor and sharpness.
After nearly 8 hours of almost uninterrupted testing, today's test was finally completed after dark, and the actual measured results showed that the actual mileage was 272 kilometers, while the meter showed that the mileage was reduced by 305 kilometers, and the remaining power was 25%, and theoretically it could also travel 100 kilometers. In the winter temperature conditions of Shenyang. The actual range of the BYD Dolphins is about 13% off, and the performance can really be said to be very good.
Why DOES BYD has such confidence to challenge the extreme cold, and the performance has been recognized by all testers, it has to be said that the BYD Dolphin car has BYD's latest e-platform 3.0 platform technology blessing.
What does BYD e Platform 3.0 bring to Dolphins?
BYD officially launched the e-platform 3.0 in 2021, as the first model of the platform, bydir Dolphin What hard-core technologies can resist the cold?
1. Eight-in-one electric powertrain can realize the peak power of the motor 270kW, the peak torque of 360N m, the maximum speed can achieve 16000r/min, and the system noise is less than 76dB. The power density can be increased by 20%, and the overall working efficiency is as high as 89%;
2. High-efficiency flat wire motor technology will increase the slot full rate by 15%. The rated power of the motor is increased by 40%, and the maximum efficiency can reach 97.5%;
3. Wide temperature range efficient heat pump system, the first refrigerant direct cooling heating type battery thermal management, reduce energy transfer links. Improve energy efficiency.
4. Efficient energy feedback IPB system. Covering daily driving conditions, the maximum deceleration feedback speed up to 0.3G;
5. Aerodynamic design.
Written in the end: BYD Dolphin in the e platform 3.0 technical support, whether it is the beauty of the exterior interior, or the actual energy consumption and driving experience, have reached a new height of electric vehicles, it can be said that BYD's electric technology is a phenomenon-level existence, constantly in self-transcendence. Through this test drive, we can see that the pain point of electric vehicle winter battery life is also gradually solved by BYD. And BYD put these hard-core technologies under the 100,000 yuan level of dolphins, making this car more competitive, perhaps dolphins will be the existence of benchmark products at this level.
