Every year, the "fig leaf" of new energy vehicles is always torn off twice. One is the first week of midsummer, and the other is when the cold wave comes.
If a "winter test" under extreme temperatures is too far away from most people's daily life, then the "severe cold mode" that has recently entered many places in the north is a true portrayal of the real winter.
Beijing ushered in the "coldest week" of the year, with the coldest night temperature reaching minus 17 degreesThe current minimum temperature in parts of North China and northern Huanghuai will be close to or below the extreme value of the same period in historyThe temperature in many places in Jiangnan and other places will drop by about 20 cumulatively;Even the people of Guangdong in the far south can already see the appearance of ice and snow. Moreover, according to **, a new round of cold wave blizzards is still on the way.
The severe cold not only torments people, but also tortures new energy vehicles and car owners. New energy vehicles can win fuel vehicles, but they can't win "providence".
Doorknobs that can't be snapped
knocked the outer layer of ice, the door handle still couldn't pop out, and I didn't know what to do with it for a while, so I had to take a taxi and leave", like Ms. Ni said, this situation has been encountered by many riders.
You may say that in severe cold weather, not to mention new energy vehicles, even the door handles of traditional fuel vehicles will be frozen.
That's right, even the hand-pulled door handles of traditional fuel vehicles can freeze in ice and snow. However, unlike the hidden door handle of new energy vehicles, the hand-pulled door handle is easier to handle after being frozen, and in many cases it can be pulled open with a little force, but it can also be used to assist in pouring some warm water or heating it slightly with a hair dryer.
Due to the hidden design, the high temperature of the vehicle after parking will melt the snow, and when the outside temperature is extremely low, ice will form, causing the door handle to be "sealed", and we have no way to pull it out. The official solution given by the car company is often a "violent solution", hitting the doorknob with a fist and knocking it open.
Not to mention that the owner is reluctant to treat his car so violently, just in the ice and snow, a person with a cold fist against the door of a car is already quite embarrassing. What you know is that you want to open the car door, and if you don't know, you think it's vandalism or theft. However, it doesn't matter if the car company is in charge anyway, as long as the owner himself is not embarrassed, it is someone else who is embarrassed.
Severely discounted battery life
If you say a door handle that can't be opened, it won't affect your car. And what about the severely discounted battery life?
The bartenders may have to say that the fuel consumption of fuel vehicles in winter will also increase, and the battery life will also decrease. But is it so outrageous that there is a discount on the battery life of new energy vehicles?
The actual cruising range is discounted by 20%, which is the norm for new energy vehicles. But in the cold season, it is the norm to discount the cruising range by four or five. Some online hailing car owners said in an interview that the actual mileage of the electric vehicles they purchased in winter was nearly halved compared with the official number of kilometers marked.
On the one hand, low temperatures affect battery activity, resulting in a decrease in the conductivity of the battery and a slowdown in the rate of charge transfer, thereby reducing the usable capacity of the battery. On the other hand, heating the battery, heating the interior of the car, defrosting and snow removal, and driving on ice and snow require more power in winter, which is more power-intensive. The superposition of multiple factors will inevitably further reduce the endurance performance of new energy vehicles. Although many upgrades have been made in battery technology for new energy vehicles, they still cannot completely eliminate the impact of low temperatures.
Batteries that don't charge up
It's still a problem with the battery, and the usable capacity is decreasing, and it's a big deal to charge it a few more times. As long as the owner himself is not embarrassed, it is others who are embarrassed. But if the charging also slows down, or even can't be charged, then it's completely embarrassing.
In winter, there are many power outages and short battery life. What's even more worrying is that sometimes it's too cold for the battery to charge. Some netizens said that it usually takes only six hours to charge, but now it takes ten hours in cold weather.
In winter, the battery has a low cycle capacity in a low temperature environment, the viscosity of the electrolyte increases, the chemical reaction resistance increases, the charging time is extended, and the lower the temperature, the longer the charging time, and it may even fail to be charged. Most of the newly launched new energy vehicles have the function of battery heating or heat preservation, which can reduce the occurrence of uncharging to a certain extent.
However, the battery heating and holding function also requires power consumption, which in turn affects the battery life. Whether to last life or keep warm is a difficult problem for car owners. On a cold day, waiting for charging in the charging station, as long as the owner is not embarrassed, it is someone else who is embarrassed.
Rear drive that is prone to slippage
After searching for "Is the rear drive car easy to slip in snow?".Various versions can be obtained. However, the overwhelming view is that rear-wheel drive vehicles are more likely to slip in snow.
The friction on the road surface decreases during the snow season, which is already prone to skidding when driving. For traditional fuel vehicles, the rear wheel drive vehicle is relatively heavy due to the transmission of engine power to the rear wheels, which makes the rear wheels easy to lose grip when "pushing the car forward", which leads to the risk of skidding when accelerating, turning or braking, and the probability of skidding will be greater than that of front-wheel drive vehicles.
In order to emphasize handling and stability, most new energy vehicles prefer to adopt the rear-wheel drive form. Although in terms of counterweight ratio, new energy vehicles can achieve 50:50 front and rear, in principle, they will not be as slippery as front-rear-drive fuel vehicles, but there is still the possibility of skidding. In particular, since new energy vehicles mainly rely on electrified components such as batteries and electric motors and electronic systems to drive and control vehicles, the stability of electronic systems may also be affected in low temperature environments.
Some experts also said that under low adhesion conditions, the performance of pure electric vehicles is not much different from ordinary fuel vehicles, unless the vehicle uses snow tires or drives a special model for this weather, the situation will be relatively improved.
Then once the rear-wheel drive car skidds and crashes, it will encounter this more headache next.
Unaffordable repairs
As the saying goes: if the new energy vehicle is not repaired, it is already repaired, and a repair is "hurting the muscles and bones".
We Predict, a data agency, conducted a survey of about 19 million vehicles from 2016 to 2021 and found that the maintenance cost of pure electric vehicles is 1 percent higher than that of gasoline vehicles6-2.3 times. According to the official statistics of the China Insurance Research Institute, the zero-to-whole ratio of the battery pack of new energy vehicles is generally more than 50%, that is to say, the maintenance cost of the battery is equivalent to half of the first of the whole vehicle, and even the zero-to-whole ratio of some models is as high as 9872%, the battery and the whole vehicle are almost the same price.
According to the actual situation, in severe cold weather, there may indeed be an increase in the maintenance of new energy vehicles. Due to the impact of the drop in temperature on batteries, electric motors, and other key components, new energy vehicles may experience various failures. In the event of a breakdown, the maintenance cost of new energy vehicles is much higher than that of fuel vehicles.
If it's a road accident that causes a bump, the situation may be even worse. Some new energy vehicles with integrated die-casting technology or all-aluminum body have almost no repair of body injuries, and can only be considered to replace the whole block, which is more costly. And if the unfortunate battery is damaged, then according to the previous survey, you may have to pay half the price of the car to repair or replace.
Write at the end:
Severe cold is the natural enemy of new energy vehicles. Twelve months a year, new energy vehicles can blow wildly for more than half a year, but there will always be two or three months that dare not speak. When everyone is trying their best to advocate the new energy vehicle's sense of science and technology, intelligence, automatic driving and other novel functions, and the playability is far better than that of fuel vehicles, this natural enemy will always come on time to stir up the situation, bringing a lot of indescribable pain points to new energy vehicle owners in actual cars. To defeat this natural enemy, new energy vehicles still need more time to upgrade their technology. Until then, you should still make a choice according to your actual situation and needs.
Don't sigh after buying a car: you don't know how good fuel is when you're young, and you mistake pure electricity for treasure.
