In this article, I am a northern Tesla model? 3 The identity of the owner tells you that when the temperature is low in winter, the battery "shrinks". ? Use my imported model 3? Take the four-wheel drive version of 499,000 (cruising range of 499 kilometers) as an example. According to the official, the full battery life is about 500 kilometers.
# Parking outdoors for one night can reduce power consumption by 80%#
There are two situations in which the battery of electric vehicle shrinks. Let's look at the first one, that is, when the vehicle is not driving, because the temperature is low at rest, the battery activity is reduced and the power is reduced.
When Model3 was parked outdoors at-0/3 12 hours, the remaining cruising range of the vehicle changed from 2 10 km to 2 17 1km and from 2 1 at night to 9: 00 the next morning. This is the case that there is no other power consumption after the vehicle is locked without power supply. The power consumption is reduced simply because of low temperature,171210 ≈ 80%.
Do you still remember this figure? Take this Model3 with a battery life of 500 kilometers as an example, it has shrunk to 80% under the condition of static low-temperature parking for one night, which is equivalent to my car changing from the officially marked 500 kilometers to 400 kilometers. 100 kilometers has just "drifted away".
# cruising range test, the power has shrunk by almost half:
Cars are for driving, not for parking. I can accept it if it shrinks by 80% just after parking for one night, but I can't stand the performance after driving.
The outdoor temperature is higher during the day than at night, and the temperature is about -5. I plan to drive to Chengde city. The overcharge distance from Diaoyutai service area to Chengde Tesla is11.5 km, and I charge it in the service area until the battery life is 2 19 km. Because the charging speed of the State Grid is slow, I don't want to wait too long, so I consider about twice the distance.
High-speed cruise fixed speed+automatic driving, 1 10 km/h, AC off, 26, three people.
When I arrived at Chengde Tesla Super Charging Station, the remaining cruising range was only 2 kilometers, which directly collapsed ... In fact, after cruising to 10 kilometers in Chengde City, the performance of the car has weakened, and I dare not accelerate overtaking, and slowly arrived at the charging station. At this time, the temperature outside the car is 0, which I think is more than that in most cities in the north in winter.
Before departure, the remaining vehicle is 2 19 km, and it will travel 1 1 km. It should be 108 km left, but actually only 2 km left ... this battery has shrunk by 50%.
I imported a Model3, with a four-wheel drive version of 499,000 (cruising range of 499 kilometers), but it has not reached the officially marked imported rear-wheel drive version of 433,000 (cruising range of 354 kilometers)?
From the above two test results, it can be seen that the legendary "Shenche Soybean 3" has greatly reduced its cruising range in the case of low temperature in winter. You know, this experimental area is not the coldest area in China. Presumably, under the challenge of lower temperature, Tesla Model? The endurance of 3 will be greatly reduced on this basis.
It seems that buying Tesla not only faces the price problem of being "cut with leeks", but also considers the IQ tax level of shrinking battery life.
