How can new energy vehicles last longer in winter?

We all know that whether it is a fuel version of the car or a new energy vehicle, it is necessary to do a good job of regular maintenance of the vehicle in order to ensure the normal operation of the vehicle and reduce unnecessary losses, especially in winter, affected by seasonal factors, many vehicles are more prone to failure than warm weather, especially the battery of new energy vehicles, as the core component of the vehicle, is more important. So, today let's take a look at what needs to be paid attention to in the winter maintenance of the battery of new energy vehicles?

First, the activity of the battery of new energy vehicles in the cold environment will be significantly reduced, so the storage capacity of the battery will also be affected accordingly, resulting in a shorter mileage, so when driving new energy vehicles in winter, try to keep driving slowly, do not often brake sharply, accelerate sharply, etc.; In addition, try not to use the on-board equipment in the car frequently, such as the radio, ** device and often turn on the air conditioner, etc., which will affect the battery life in winter.

Second, in winter, try to park new energy vehicles in the underground garage, try to choose indoor charging, outdoor too low temperature environment will seriously affect the efficiency of charging, in case of heavy rain and snow, but also may damage the charger; In addition, do not charge the battery for a long time, but charge the battery correctly and reasonably according to the actual situation and practical frequency of the vehicle, otherwise the service life of the battery will be shortened.

As we all know, fuel vehicles have water tanks, which can use the waste heat of the engine for heating, and there is almost no additional consumption in the whole process. But the new energy vehicle is different, it can only provide heating by using electricity, so turning on the air conditioner will consume a lot of electricity. In the process of using the car, we need to pay attention to the fact that when the air conditioner is turned on, do not turn it on too much, and the heater only needs to maintain a normal body temperature so that the body does not feel cold.

The air volume should not be too large, basically 1-2 gears, you can blow a relatively warm wind.

In addition, you should also regularly go to the 4S shop to do regular maintenance and inspection of the vehicle's battery, especially the density of the electrolyte and the circuit of the battery, which should be checked by special personnel to avoid damage to the whole battery caused by some minor problems.

All in all, the battery as the core of new energy vehicles, only good maintenance and maintenance can make it last longer, bring a better experience to users, some of the winter battery maintenance methods described above, car friends can learn from.

Lithium batteries have an impact on the range in the cold winter.

Lithium-ion batteries work on the principle that the electrolyte inside changes through a chemical reaction, and a potential difference occurs at the positive and negative electrodes to produce an electric current. In a low-temperature environment, the electrolyte moves quite slowly, which affects the transfer activity of lithium ions between the positive and negative electrodes, resulting in a decrease in the charging and discharging performance of the battery.

To put it simply, in a low-temperature environment, it is not that the lithium battery is really dead, but that there is power but cannot be released normally. According to analysis data, the capacity of ordinary lithium batteries will be reduced by 20 at zero degrees Celsius, and when it reaches minus 10 degrees Celsius, the capacity may only be about half.

Extended Information: Precautions for Winter Use:

1. Find a warm place to charge.

When the ambient temperature is lower than 0, charge the electric vehicle, the system will automatically heat the battery cell first, and when the temperature of the battery cell reaches more than 5, it will really start charging the vehicle. Some EV owners feel that charging their EV in the winter suddenly slows down, which is actually an extra time to heat up the battery cells before charging the vehicle.

Therefore, when the car owner usually charges the car, he should try to choose the underground parking lot, closed garage and other places. This helps to improve the activity of the battery, which not only reduces the loss of range, but also improves the efficiency of charging and saves time.

2. Charge the battery for a short time before traveling.

The day before, the electric car was still 60 or 70 percent charged, but the next morning it was only 30 percent or less charged. Some people call this situation "running electricity". In fact, this kind of "running power" is not a failure, but a fault caused by low temperature.

In the process of driving the electric vehicle, the battery is in a state of continuous discharge, the temperature will be relatively high, and the voltage of the battery is relatively high.

However, after being parked in a low temperature state for a whole night, the battery has cooled down and the voltage drops, at which point the car's system will automatically adjust the displayed power and range, which creates an illusion of "running power". In this case, you generally only need to go out in advance and charge the battery for about 10 minutes.

3. Drive steadily and don't be in a hurry.

When driving an electric vehicle, you should accelerate slowly and avoid intense driving methods such as deceleration, sharp turns, and sudden braking. Good driving habits can effectively reduce the rate at which the battery drains power. The time to start the car should not exceed 5 seconds each time, and the interval between starting again should not be less than 15 seconds.

If the battery mileage drops too much, you should go to the 4S store in time to check the battery of the car, replenish the electrolyte of the battery in time, and adjust the specific gravity of the electrolyte.

The activity of the battery of new energy vehicles will be significantly reduced in a cold environment, so the storage capacity of the battery will also be affected accordingly, resulting in a shorter mileage, so when driving new energy vehicles in winter, we should try to keep driving smoothly, and do not often brake and accelerate sharply; In addition, try not to use the on-board equipment in the car frequently, such as the radio, ** device and often turn on the air conditioner, etc., which will affect the battery life in winter. In winter, try to park the new energy vehicle in the underground garage, try to choose to charge indoors, the outdoor temperature environment is too low will seriously affect the efficiency of charging, and the charger may be damaged in heavy rain and snow; In addition, do not charge the battery for a long time, but charge the battery correctly and reasonably according to the actual situation and practical frequency of the vehicle, otherwise the service life of the battery will be shortened.

New energy vehicles should take thermal insulation measures in winter, and at the same time often charge them. This will allow for a longer range.

Park in the garage when not open because the temperature inside the garage is high.

Do not turn on the heater, because turning on the heater is very power-intensive and will reduce the range.

Don't listen to ** while driving, because the car stereo also consumes a lot of power.

1. The shortening of the cruising range in winter is related to the charging environment temperature.

In winter, many car owners will encounter such a situation: yesterday there was 90% electricity, after a night, found that the power declined seriously, this is because in the low temperature environment, the activity of the power battery electrode material is reduced, the lower the temperature of the chemical material, the worse the activity of the material, and the battery storage power will decrease. But you don't have to worry, this is the normal attribute of the power battery, when the temperature returns to normal temperature, the battery storage power will decay and decrease.

Therefore, if you can go to an underground parking lot or garage to park and charge, or you can charge it when it is relatively warm during the day, this will help improve battery activity and reduce the loss of range. Of course, many mid-to-high-end electric vehicles now have a battery temperature control management system to withstand the lower temperatures in winter.

2. Charge in time and charge at any time.

Before charging, check the vehicle charging port, ensure that the use environment is ventilated and dry, and charge the car in time after each use of the new energy electric vehicle to avoid power loss, which will affect the car and the battery to cause damage. In addition, charging in time after use can also reduce the battery warm-up time, because the temperature of the battery is relatively high after the vehicle is used, and it can also improve the charging efficiency. Remember, do not charge the battery for a long time, but charge the battery correctly and reasonably according to the actual situation of the vehicle and the frequency of use, otherwise the service life of the battery will be shortened.

3. Plan your itinerary in advance.

How to make new energy vehicles better serve us and avoid the problem of breaking down halfway due to insufficient battery life, it is very important to plan the route in advance. At present, the actual cruising range of the mainstream of new energy vehicles is between 300 kilometers and 500 kilometers, therefore, under your car conditions, under the frequency of use, a charge can meet your needs for many times, only by calculating this demand can electric vehicles serve you with peace of mind anytime and anywhere.

4. Reasonable tire pressure and tire cleaning.

Every winter, when the temperature drops, the rubber tires of the car will become hard and brittle, and the air pressure will be too low to produce soft tires, and the soft tires will accelerate aging at low temperatures, intensify the friction with the ground, and reduce the service life of the tires. If the tire pressure is too high, it will be easy to puncture the tire and affect the driving. In addition, we have to clean the tread inclusions frequently.

5. Develop good driving habits.

Driving habits are more extensive, in new energy vehicles, due to the explosive particularity of the output horsepower of the electric motor, usually our driving will have a certain impact on the mileage, so the driving should be as smooth as possible, to avoid emergency acceleration, emergency braking and other rough driving methods. If you don't drive the vehicle in winter, you can fully charge the battery in advance and ensure that the battery is charged every once in a while to ensure the activity of the battery. All in all, the use of new energy vehicles in winter is insufficient compared with fuel vehicles.

Don't drive at a loss of power, charge it in time.

Come and check Why the winter battery life of new energy vehicles has been shortened At present, there are two main types of power batteries used in new energy vehicles: ternary lithium batteries and lithium iron phosphate batteries.

The disadvantages of new energy vehicles are very obvious, the first is the problem of battery life, and the second is the replacement of the battery, the third is the cost of maintenance, and the last is the inevitable environmental problem.

Although the new energy car is more convenient than those manual and automatic cars, there is not so much cumbersome process, but it is very expensive, and it has to be charged, there are certain drawbacks, and the charging car will generally be greatly reduced in winter, which is also a problem to be discussed in the research and development process, and it is also a commonplace topic.

The problem of new energy car endurance is indeed one of his drawbacks, but it is not the most difficult one of all problems, because many people buy new energy vehicles for convenience, generally speaking, hundreds of kilometers are enough for everyone to drive, but there are many people who have a relatively high demand for this kind of car, so they hope to be able to last hundreds of kilometers, and now part of the new energy vehicles have achieved a range of 700 kilometers, but such cars are also very expensive.

This is the second problem of new energy vehicles, that is, the cost is relatively expensive! It is more troublesome to repair, and there may be many people who cannot afford to keep such a car. Although it is simple to drive, it is not the same as a fuel car, because many people are afraid to go directly to the repair.

The consequences of a short circuit in the circuit are very serious. <>

The last one is the battery replacement. Generally speaking, the battery of an electric car is very important, for example, the battery we usually drive, and it takes hundreds of dollars to change the battery, and some people don't want to change it for two or three years, so they change the car directly. Replacing the battery of a car like this may cost tens of thousands of dollars, so many people don't want to drive, but they can't afford to drive.

Nowadays, many people prefer to drive manual cars, the first one is because they are used to it, and the second is because it is cheap. A car with automatic transmission, even when studying, is expensive, and it is the same as buying a car. However, it has become a trend to drive an automatic car, and if you think that electric cars are not good, then buy an automatic transmission.

Yes, because the temperature in winter is relatively low, there will be some problems with the battery, there is no way to charge it well, and the driving distance is relatively short.

I don't think it's the biggest disadvantage, the biggest disadvantage is the battery life, the battery consumption is particularly powerful, and the battery is particularly easy to not store power.

Yes, because in winter many car owners will turn on the heater, the power consumption is very large. The cruising range does not meet the requirements of consumers.

If you buy an electric car in Beijing 1You must have a car purchase index, and the application conditions are the same as those for applying for ordinary oil vehicles, but the probability of winning the lottery is higher; 2.You have to be clear about which electric vehicles can be subsidized, and make up for Hongtong subsidies to divide national subsidies and local subsidies.

In Beijing, plug-in hybrid models are not subsidized and have a separate lottery, and pure electric vehicles are not restricted; 3.You have to understand in advance whether your community agrees with you to install a personal charging pile, if you don't agree, you have to solve the charging problem first, and then consider whether to buy a new energy vehicle. Next, let's talk about the places to pay attention to when choosing an electric car model:

1.Look at the brand, choose a brand that has been operating electric vehicles for a long time and has a good reputation among friends around, such a brand is generally less credible and may have better quality, such as BYD, BAIC, etc.; 2.Look at the merchants, the merchants who sell electric vehicles should have a certain scale, pay attention to the supporting services of electric vehicles, and ensure that the after-sales service can be guaranteed, such as 4S stores directly operated by major brands, United Electric, etc.; 3.

Look at the model, the current electric vehicles are miniature, ordinary, SUV, etc., mainly depending on what you buy a car for, if it is simply to work, you can consider the micro Zhidou D2, small and easy to drive, if it is for family use, you can consider SUV, large space; 4.Look at the accessories, the most critical thing for electric vehicles is the problem of battery and motor power, the greater the motor power, the greater the power, the speed is significantly faster than the small power when going uphill, the largest electric vehicle power on the market is 1500W, but the power consumption is also large. It is recommended that you choose an electric car with a power of 500W-800W, so that the climbing ability is not bad and the power consumption is not too large.

As for the battery, the batteries used in electric vehicles on the market are 48V, 60V, 64V, 72V, 74V, 80V, with a capacity of 16Ah-24Ah, the higher the voltage, the better, because the higher the voltage, the lower the current of the motor at the same power, the longer the discharge time, so that the mileage of the electric vehicle is far, and the larger the battery capacity, the more durable the battery! Therefore, in the same case, you should choose an electric vehicle with a battery with high voltage and large capacity; 5.Look at the mileage, mainly related to the use, if you are only active in Beijing, 200 kilometers of mileage is basically enough; 6.

Test drive, be sure to test drive, some cars will have imperfections in the assembly, pay more attention to whether the brakes are flexible when testing the car; Whether the sound of the motor is normal, whether the lights and instruments are normal, etc.
