The DFLZM experimental team tested the automobile performance at high altitude and low temperature

The test team fought in Mohe, the northernmost and coldest city in China. The ambient temperature was -5℃ to -40℃, and the test required -5℃ to -25℃. When getting on the car every day, it felt like sitting on ice.

 

Affected by the epidemic situation, they were forced to stop the experiment and cooperate with the local authorities to carry out nucleic acid detection for all members of the epidemic-free community. In the morning, researchers need to queue up for nearly 1 hour in the snowy weather of -30℃ for nucleic acid detection. Their clothes are covered with snowflakes, their faces are frozen and numb, their eyebrows are frozen and their hair is white, even their gloved hands feel frozen and numb.

 

The weather in Mohe is -25℃, and they can keep warm when wearing bread shoes and gloves outside. When the temperature is above -30℃, their hands and feet are frozen and numb, and the exposed parts of their faces are even numb to pain.

 

 

 

The endurance test of SX5GEV heat pump model and non-heat pump model is compared with the standard Aeon V model. Under the temperature of about -10℃, the automatic air conditioner sets a uniform temperature, and starts synchronously to compare the endurance mileage of urban road conditions and high-speed road conditions at 1:1.

 

 

 

 

 

 

 

 

On Mobei Highway, which has been snowing for two consecutive days, the intersection is half a meter thick with snow, so the car can't turn around until it sees the intersection that has been crushed by the car, and then it can turn around with the wheel marks.

 

 

 

 

 

 

The test team needs to drive for 3 hours every day to and from Arctic Village, and use high-power heating or cooling method to conduct transient control. When the temperature inside the vehicle reaches the preset temperature, it will be switched to steady control, and the heat energy inside the vehicle and the heat energy flowing out of the vehicle will be in a balanced state, so that the vehicle can complete the evaluation and optimization of transient and steady control under as many environmental conditions as possible, so as to obtain the best control calibration and meet the technical index requirements of the vehicle leaving the factory.

 

 

Mohe City is located at the northern foot of Daxinganling Mountains, the northernmost part of the motherland, and is known as "China Arctic".

 

 

The year 2023 has arrived, which means that another experiment is about to start. The pace of the test team has not stopped, so we have to move on and help Liuqi test research and development.
