In the past two years, there are more and more brothers who buy new energy, and I myself have received a lot of test drives of new energy models, and in the past 2 months, I have basically been driving a variety of different green cars, and then I found that after entering the winter, there are still many differences between new energy vehicles and traditional fuel vehicles, so today I will talk to you about what are the precautions for new energy vehicles in winter, if you also plan to buy new energy vehicles, then this ** will definitely be able to help you.
The first is the most important point, the issue of security. Nowadays, many green cars use a rear-wheel drive layout, and the motor itself has a lot of torque, so unlike traditional fuel vehicles, their rear tire pattern wears out faster.
The most exaggerated thing I have ever seen is a Tesla Model Y that I drove before, and in just 1 year, the original rear tire pattern has been worn to the warning line, which is very dangerous on the slippery road in winter.
Therefore, the old brother who drives new energy vehicles, especially rear-drive new energy vehicles, must check the tread of the tires themselves before the snow, especially the rear tires, to see if the tread is still higher than the warning line inside the pattern.
The second is the problem of tire pressure, many new energy vehicles will use tires with a small flat ratio and a thinner tire wall, so once the temperature drops, the reduction in tire pressure is obvious. The lower tire pressure, firstly, will lead to a more likely puncture, and secondly, it will significantly increase the energy consumption of the tram, which has been tested by many tram brothers on the Internet.
So replenish the tire pressure in time before the winter cools down, and you can even beat the tire pressure to slightly higher than the standard tire pressure of 02 bar to prevent a drop in tire pressure due to further cooling. For example, the original factory requirements of this car green brand car 2With a tire pressure of 5bar, we can actually hit it up to 27 bar to prevent a colder next month. Of course, after the beginning of spring, the tire pressure will rise, and you must remember to deflate in time.
Next are the two points that need to be paid attention to in the winter body maintenance of new energy vehicles, the first is the door handle. Although the hidden door handles are beautiful and can also reduce the wind resistance of the body, they also have the problem of freezing in winter. If you want to completely avoid this embarrassing situation, it is actually very simple, you can refer to the recommendations of Tesla's maintenance manual, and you can solve it with WD-40.
First pull the handle apart, find the shaft spring inside the handle, then connect the WD-40 to the conduit, aim at the position of the spring and spray it, and then repeatedly open and close the handle 8 10 times to let the WD-40 fully penetrate into the gap of the spring. Because it has the function of lubrication + water displacement, it can not only make the handle open and close the door more smoothly, but also prevent the water vapor from freezing into ice on the spring, effectively preventing it from being frozen. Of course, you'll have to do this before it snows heavily, so it's important to have a bottle of WD-40 on board.
The second is that many new energy vehicles use frameless doors, when the door is opened, the window will automatically drop a little bit to avoid the sealing strip above, if it is frozen and cannot be lowered, then the window has the possibility of being damaged.
Therefore, it is necessary to use WD-40 high-efficiency silicone lubricant to fully lubricate the track of the window before it is possible to freeze.
The silicone oil film formed in the track not only effectively lubricates the windows, but also restores the elasticity of the rubber sealing strip, reduces the probability of the windows being frozen, and protects the glass. Therefore, you can also wipe it with a towel on the sealing strip of the door, which can also play a role in maintaining the adhesive strip, delaying the aging of the adhesive strip, and preventing the embarrassing situation of the door being frozen.
Next, there are several energy-saving tips for new energy vehicles in winter. First of all, if your green car has a large canopy, then make sure that it is fully open and the most transparent. Although in summer, the canopy is not insulated and criticized by everyone, but in winter, it has become its advantage not to insulate, especially in the sun, it can effectively reduce the working pressure of the tram air conditioner, and the sunshine greenhouse belongs to yes.
The second is to try to choose to charge in the basement or indoors, because the battery activity of the tram or oil tram will be reduced in a low temperature environment, and charging will affect the efficiency very much at this time, and there will be a discount in the charging amount or a longer charging time. Because there is no charging pile in my community, I can only charge outdoors before every test drive, and the car that was originally full in 30 minutes in summer now has to wait for it for 1 hour, which is really tiring. If you're like me and can only charge outdoors, then my suggestion is to charge the car immediately after using the car every time you run out, which is slightly more efficient than charging the next day with a "cold car", after all, the battery also has temperature changes.
The second is to drive the kinetic energy to the maximum, I know that many old brothers who have just driven the tram are not suitable for this, but in fact, I have driven it for so long, and I feel that this is actually very easy to use, especially in winter, for the cruising range that is greatly affected by temperature, there is still a significant gain effect.
But there is also a point to note, some models such as Tesla, when the temperature is too low or just fully charged, there will be a limited kinetic energy, if you turn on its "kinetic energy** compensation braking", then the brake pedal will automatically drop a little, and the brake will feel harder, this is a normal situation, not that your car can't brake.
The above 7 points are the winter car skills summarized by my test drive of various green cars, I hope to help you who have a green car or plan to buy a green car.
