At present, although the acceptance of new energy vehicles is already very high, they still face an insurmountable problem – low temperature.
Low temperature will cause the battery to attenuate very seriously, resulting in a significant decrease in battery life and charging efficiency. Many manufacturers will be equipped with heating technology to ensure the temperature of the battery pack to ensure the experience.
According to CCTV news reports, a number of new energy vehicles have recently completed winter tests in Yakeshi and Genhe, Inner Mongolia.
The winter test of new energy vehicles covered more than 60 models of 34 brands, of which domestic models accounted for 80%. In addition to the basic tests such as battery life and charging at -15°C, this test also designed projects such as assisting driving in snow, freezing challenges at -30°C, and ice and snow climbing.
The test results show that the average endurance of all models in low temperature environment is 48.47%. The average cruising range of domestic new energy vehicles exceeds that of joint venture products by 3.36 percentage points, and domestic brands have obvious advantages.
In addition, in terms of low temperature charging efficiency in winter, the charging time and charging power of domestic new energy vehicles are basically not affected by low temperature.
Wang Zhenpo, director of the National Engineering Research Center for Electric Vehicles, said: Under low temperature conditions, the driving range of new energy vehicles will be reduced due to the impact of power battery performance. When driving a new energy vehicle under extremely cold conditions, everyone should pay more attention to the mileage displayed on the dashboard and provide corresponding charging services in time.
Especially as the Spring Festival is approaching recently, many people choose to drive home by themselves. Friends in the north must pay attention to the power of their cars and charge them in time.
