Wuling Hongguang MINIEV is hot in the electric vehicle market, so can the car stand the "test" of high temperature in summer? Let’s take Wuling Hongguang MINIEV 2022 macaroon Zhenxiang Ferrous lithium phosphate as an example. Let’s take a look.
Test model: Wuling Hongguang MINIEV 2022 macaroon Zhenxiang Ferrous lithium phosphate.
Test temperature: 40 degrees to 49 degrees outdoors.
The maximum speed of this car is 100km/h, and during the speed test, the car starts relatively fast and accelerates to the rear, and it takes a long time to complete the journey from 50km/h to 100km/h, and the measured maximum speed of the car can reach 101.31km/h, which is basically consistent with the official results.
During the high-temperature continuous acceleration test, the test interval is 1 minute, and the acceleration lasts for 10 times. The shortest measured acceleration time of 100 kilometers is 21.84 seconds, and the motor performance is not obviously attenuated.
So what is the reliability performance of the battery at high temperature? The car is verified by high temperature endurance and fast charging ability. Before the high-temperature endurance test, the air conditioning temperature was set to 24 degrees, the automatic mode, the driving mode was adjusted to the economic mode, and the kinetic energy recovery was the strongest. The car completed the endurance test at an average speed of 80 km/h. Under the high-temperature and high-speed working conditions, the measured cruising range of this car was 113.6km/h, and the pure electric cruising range of the Ministry of Industry and Information Technology was 170km, with a cruising achievement rate of 66.8% and a high cruising achievement rate.
It is worth mentioning that the endurance test went to zero, and the tire pressure of the vehicle began to alarm. After the test, the measured tire pressure values were all normal, which was judged as accidental failure. At high temperature, the driving quality of the car performed well.
During the high-temperature charging test, the AC slow charging pile with power of 7kW was used. The high-temperature charging test of this Wuling Hongguang MINIEV was stable. It took 596 minutes to fully charge and charged 15.7kWh of electricity. There was no abnormality during the slow charging process, which was basically consistent with the official slow charging of 9 hours.
When parking in summer, exposure is indispensable. When Wuling Hongguang MINIEV is baked at a high temperature above 40 degrees for more than 2 hours, the temperature inside the car reaches about 56 degrees. In the area where the car is in direct contact with the human body, the average temperature reaches over 68 degrees. The hottest place inside the car is under the windshield, and the temperature is 82.5 degrees. This car is equipped with a fabric seat, which is not as hot as a leather seat, and the glass is isolated from ultraviolet rays and infrared rays.
In fact, riders are more concerned about the cooling capacity of the air conditioner and the ability to quickly cool down inside the car after parking outdoors. After exposure, the air conditioner of this Wuling Hongguang MINIEV was adjusted to the strongest cooling mode. After half an hour, the temperature inside the car dropped to 30.7 degrees, and the cooling capacity of the air conditioner performed well. At the same time, in the first 10 minutes, the air conditioner can reduce the temperature inside the car to 11 degrees, which is more competitive than that of the same class.
Generally speaking, the motor performance of this Wuling Hongguang MINIEV model is not obviously attenuated in summer, and the battery performance of the car is stable. The cooling capacity of the car air conditioner and the ability to quickly cool down the car are more competitive, and the quality of the car is good, which has withstood the high temperature test.
