If electric vehicles have natural enemies, it must be a cold winter! In the eyes of many people, driving an electric car in the winter is a living sin, not so much a trip as a test. However, humans may be the only creatures in the world to be tested, and we invited three tram owners to take a 206-kilometer-long winter trip at temperatures of -25°C. This time, we must not only talk about the car, but also smell the wind, talk about the snow, see the sunset, look at this winter trip from a new perspective, and listen to what the three owners have to say.

Before you go, take a walk through the streets of Changchun
Although Tesla owners - Yuanyuan and Volkswagen owners - Xiaodong are both northerners, they have not stayed for a moment to enjoy the northeast. Geometric C owner - Jiang Nan is a Shanghainese, he is as happy to see the snow on the ground as full of money, he as a homestay owner naturally loves to travel, this self-driving is with a very optimistic attitude to come, the excitement is enough to infect everyone around, including the other two car owners. In order to ensure that the power of the trip is sufficient, the three cars are fully charged at the same charging station, and the next day the three owners pick up the car together and walk in the streets of Changchun before picking up the car.

It's a good thing to be happy, but heaven has a bad habit of pouring cold water. Before the official departure, Yuanyuan's Tesla Model 3 may be because the gap is too large to cause cold intrusion, the window and handlebar are frozen and closed, and they have not been hit with a stick before they start. Fortunately, Jiang Nan took out the hot water in his thermos cup and solved this problem. This pot of hot water was originally prepared by Jiang Nan for geometric C, and he knew that the hidden handlebars were at risk of being frozen, and he did not expect that the real problem was Tesla. Fortunately, the problem was finally solved, and Yuanyuan and Tesla were warmed up.

Maybe the day this plate of cold water is a bit much, Yuanyuan's Tesla Model 3 because it is a lithium iron phosphate battery, the low temperature resistance is very poor, the first 15 kilometers on the drop of 10% of the electricity, anxious to make her shout bad. I don't know what she thinks, thinking that the wind resistance in the front of the car is too big, and she wants to follow behind and eat the tail stream. I don't think the 120KMH speed limit is necessary to eat wake streams, maybe it's a little burdensome to do so. Xiaodong was reluctant to lead the team on the grounds that the Volkswagen ID.4X already had a lot of wind resistance. Jiang Nan was very willing to take on the leading role, and he also wanted to measure the performance of Geometry C on the snow road.

Sitting in Geometric C, I also experienced it once. To be honest, the comfort of the ride and the stability under the snow road are much better than imagined, and the texture is not like a hundred thousand cars. Jiang Nan also revealed his views on using the car in the chat with me, he was originally a pragmatist, and it was his criterion to buy right or not to buy expensive. "I've driven the Tesla Model 3 a few times before, and my geometry can reach its eighty or ninety levels, which I think is worth it considering the price." I talked to him for a while, during which I also tried the adaptive cruise of geometry C, the recognition and accuracy are still quite high, the strength is still ok, I agree with his point of view. Chatting along the way, we arrived at the middle station, Rime Island, before noon.
Rime Island doesn't have rime, but owners can play with it
"If things have the potential to go bad, no matter how small the possibility, it will always happen." Murphy's Law does not deceive me, when the national cold wave hit, Shanghai is snowing, there is no snow in the northeast, and there is no rime on rime island. After the crew was busy filming the camera, after the three car owners took a brief stroll, they were more interested in each other's cars.
Yuanyuan and Xiaodong are both very interested in Geometry C, after all, he is the cheapest car and the car with the most remaining endurance. Jiang Nan also talked about his pragmatism principles, and then explained the advantages of geometry C for us in depth, it seems that geometry owners are people who love to do homework. First of all, the geometric C table shows high battery life because of "quasi", the mileage algorithm of geometric C is different from the BMS system that generally only calculates the battery level, but the VCU controller integrates the driving data, driving style, and residual power for multi-dimensional calculation, which is the unique SEM energy management system of geometry. Secondly, geometry C improves endurance through multiple combinations of energy lifting and energy control, and the "electric drive waste heat recovery system" can also increase the endurance by 4% through the heat recirculation of the electric drive, and the low temperature below zero degrees can also increase the endurance by 4%. The "Battery Temperature Control System" can increase the battery temperature by 10°C in the environment as low as -55°C, which is very effective in reducing power consumption. It also has a "battery insert gun guarantee preheating" to ensure that the battery temperature is in optimal condition at the time of departure, which is particularly useful for winter cars.
This large-scale science popularization scene stunned the other two car owners. Since it is not geometric, several car owners simply played directly. The most unfortunate Yuanyuan on the road took the lead in throwing a snowball at Jiang Nan, and Xiaodong and I took advantage of the fact that he had not yet reacted, and quickly smashed a large repair knife. Jiang Nan's playful personality was provoked by us, and he even tried to counterattack us. On Rime Island without rime, we had a snowball fight for half an hour, and the geometry owners really loved to play!
In the face of Tesla and Volkswagen, geometric owners show their demeanor
After a hurry, the three cars finally reached Songhua Lake. However, Tesla has completely run out of power, and the return trip can only be towed back by car. The relatively surplus Geometry C and Volkswagen ID.4X are busy framing. Jiang Nan found a place with a good view and asked me to take a few pictures of him. He is very satisfied with this cold winter trip, the big winter to drive an electric car self-driving tour and must be a living sin, as long as you have a reliable partner, you can still see the snow in the northeast, Sanya sun, he thinks that geometry C is such a good partner. Yuanyuan, who has run out of electricity, also came here to take a group photo with Geometry C.
Considering that It takes more than 2 hours for Yuanyuan's Tesla to wait for the trailer, Jiang Nan still let Yuanyuan go back with his own geometric C. However, a wave of uneven waves, when we returned to the charging pile from Songhua Lake, the Volkswagen ID.4X entered the turtle speed mode because the battery capacity was too low, perhaps in order to save power, the air conditioner was automatically turned off! Because the air temperature difference between the inside and outside of the car is too large, a large amount of fog is generated on the windshield, which seriously affects the field of vision, when the sky is completely dark, the Volkswagen is the head car, Xiaodong can only pull over for the first time when encountering this situation. In contrast, the heat pump air conditioner of the geometric C, unlike the Volkswagen PTC heater, will only consume battery power, but with the help of heat from outside the car to convert into the car, it is the best solution for the current tram air conditioning. Under the consultation, Jiang Nan, who has the longest driving experience, took the initiative to ask the Volkswagen ID.4X without air conditioning to let Xiaodong, who had driven a car for a day, sit on the geometric C and rest well. This move was a bit unexpected, after all, Jiang Nan himself had driven all day. In the face of the difficulties encountered, the geometry owner showed his demeanor.
In the end, looking back at the whole process, the most expensive Tesla Model 3 has long been nestled and has become the most crotch-pulling one. The Volkswagen ID.4X has 74 km of endurance left, and is late due to air conditioning problems. Geometry C has 195 kilometers left, and the owner Jiang Nan has become the person who contributed the most to this journey.
Write at the end
The cold winter temperature not only tests the endurance, but also tests the workmanship quality of electric vehicles, air conditioning settings, thermal management and other aspects. Geometry C's performance in this time is very eye-catching, with a product strength of far more than 180,000. Naturally, its owner, Jiang Nan, has also become the person who enjoys the winter trip the most, and said that he will challenge it again next year when he has the opportunity.
