As a "double La Niña year", this year's winter in the north is particularly harsh, minus 20 degrees is a common thing, for friends in the northern region, this is just a common thing, down jacket hat gloves are fully armed, into the house has heating, carrying will pass, but electric vehicles are not as cold as people, in the case of low temperatures, the endurance decays sharply.
The owners of electric vehicles have to suffer a double blow of physical and psychological, go out afraid of loving the car, dare not open the warm air, freeze in the car, and even cover the quilt to drive. In addition, you have to suffer psychological torture, far from guessing how much electricity will fall out of a night, and do not know whether the current 15% of the power will suddenly change to 0 in the next second, but also suffer from the group ridicule on the Internet, not to mention how bad the mood is.
Get up at 4 a.m. to grab a charging pile
Recently, CCTV financial reports, many Beijing electric vehicle owners, 4 a.m. up to grab electric vehicle charging piles, the reason is that Beijing Shunyi Niulan Town kindergarten near the public charging pile, night 11 o'clock to 7 a.m. is the trough period electricity price, 6 cents cheaper per kilowatt-hour, and no parking fee, originally there were 10 charging piles, but many car owners parked the car here on the first night to charge, full and not moved, resulting in available charging piles often only 2-3, As a result, in order to save 30 yuan in charging costs, car owners got up at 4 a.m. to grab charging piles.
The reason why I fight so hard is only because of the compulsion of life. 1 kWh of electricity 1.07 yuan in the trough period, charging 1 kWh of electricity during the noon peak period is almost 1.7 yuan, and many pure electric models, although the nominal endurance is 500 kilometers, but in the case of low temperatures, they can only run to more than 200 kilometers, many online car drivers need to charge twice a day, many charging piles in the urban area, each kWh of electricity is about 2 yuan, some parking lots also have to charge parking fees, and charging here, 1 month can save more than a thousand yuan. A ride-hailing driver helplessly said, "You have to run a lot of orders to earn more than a thousand commissions, and if you can save a little, save a little."
Of course, there are also many online ride-hailing drivers who choose to change the battery, "the battery that is replaced is not fully charged, the power is less than 95%, and it is not used more than it is charged by itself." Now I basically pay 0.35 yuan per kilometer, and the electricity bill is more than 100 yuan a day. "Calculated down, the cost of changing electricity is also relatively high, calculated down, in fact, the use of pure electric models in winter to run operations, not much cheaper than fuel vehicles."
Add firewood for electric vehicles
There are also many electric vehicle owners who choose to add firewood to their cars, for the simple reason that the heating air is too power-consuming.
Most of the online car, the use of TPC air conditioning, that is, the material of the household radiator, the power is very high, the original is not high endurance, in the case of opening the warm air is more stretched, therefore, many online car drivers choose to try not to open the warm air, wear more clothes, only when carrying passengers to open the warm air. And many car owners who can't bear the freeze choose to install firewood for warmth. That is, a small fuel tank is added to the inside of the front bumper of the vehicle, and diesel fuel is added to the tank, and diesel combustion is used to deliver warm air to the car.
Chai nuan was originally used for winter heating products on large trucks, but it has changed into a heating artifact for many electric vehicle owners, the modification price of chai nuan is low, the cost is about 1,000 yuan, the heating efficiency is high, the heating cost is low, the most critical thing is that chai nuan does not affect the endurance of the vehicle, for many online car-hailing, time is money. But how would a gas station feel if it saw an electric car refueling diesel?
The popularization of electric vehicles has a long way to go
The reasons why electric vehicles become electric daddies in winter are caused by many aspects.
On the one hand, because of the endurance decay of the electric vehicle itself, the fluidity of the lithium-ion battery in the case of low temperature is reduced, resulting in a decrease in capacity, a decrease in charging power, if the warm air is turned on, the endurance will be greatly attenuated, in the media's winter endurance test, in the case of minus 15 degrees, the mainstream electric vehicles on the market, the endurance has been slashed, none of them are spared.
On the other hand, because the charging facilities can not keep up, according to the data, as of September 2021, China's new energy vehicle ownership reached 6.78 million, as of November 2021, the cumulative number of charging infrastructure in the country is 2.385 million units, it seems that the ratio of electric vehicles and charging facilities can reach 3:1, but a large number of charging piles idle, charging pile use efficiency is also a real problem.
Under the premise of private piles, the use of electric vehicles has a good experience, but the problem is that many communities are old residential areas and cannot install private piles, and some electric vehicle owners have not bought private parking spaces at all, and they cannot install charging piles at all.
In the future, before solid-state batteries or even hydrogen fuel cells are officially commercially available, the embarrassing problem of electric vehicles in winter will remain for a long time, so it is still that sentence, for users in the northern region, hybrid models may be a more suitable choice.
