How many kilometers is the range of new energy vehicles?

Different brands of new energy vehicles have different mileage, Xpeng Motors P7 pure electric range: 552-706 kilometers, fast charging time 05 hours, slow charging hours; Tesla Model 3

Pure electric range: 445-668 km, fast charging time 1 hour, slow charging 10 hours; Roewe Marvel X pure electric range: 403-665 km, fast charging time hours, slow charging hours.

From the point of view of battery development, it is not impossible to cope with a range of 1000 km on a single charge. In addition to using more battery packs, range can be increased through more advanced batteries, functional restoration, and better battery management systems, and even more advanced autonomous driving systems. Taking the development of battery technology as an example, the effect of ternary lithium batteries is better than that of lithium iron phosphate batteries.

The battery of lithium iron phosphate battery can reach 150wh kg, which is already excellent, but ternary lithium battery is easy to roll. The team is also working on high-precision products such as aluminum-air batteries and graphene batteries.

The warranty period of the power battery of electric vehicles shall not be less than 8 years or 120,000 kilometers, and when the attenuation of the power battery reaches more than 20% during the warranty period, it shall be replaced free of charge. It can be seen from this industry regulation that the service life of new energy vehicles can reach at least 8 years or 120,000 kilometers. Of course, the use of a car is not judged by the warranty period.

In actual use, the warranty period is the basic judgment. It should also be judged according to the use of the vehicle and the vehicle design criteria. The biggest difference between new energy vehicles and fuel vehicles lies in the power system, and the key to the power system is the power battery.

There are two main types of power batteries used in new energy vehicles: lithium iron phosphate batteries and ternary lithium batteries.

The number of ternary lithium batteries is generally 1000 1500 times, judging from the material time, it is much simpler, and the material life can be at least 8 to 10 years. Knowing the life cycle of an electric battery, let's take the actual car to convert. Taking ternary lithium power battery as an example, a vehicle with a range of 400 kilometers, even if the power battery is cycled 1,000 times, it will have to travel 400,000 kilometers to achieve 20% attenuation.

Of course, in actual vehicles, the service life of the power battery will be shortened due to external influences. The theory is 400,000 kilometers, but the reality is 20%, which is 320,000 kilometers. Most people use the car for less than 20,000 kilometers per year, and 320,000 kilometers can be used for 16 years.

The warranty of the power battery cannot be less than 8 years or 120,000 kilometers, and when the power battery capacity is attenuated to less than 80%, it needs to be mandatory, and it is reused step by step. Below, let's briefly analyze how many years and how many kilometers can be driven when the power battery is attenuated to 80%. At present, there are two main types of power batteries on the market:

Ternary lithium battery and lithium iron phosphate battery. The number of cycles of ternary lithium batteries is about 800-1000 times, while the number of cycles of lithium iron phosphate batteries is about 2000-3000 times, but the energy density of ternary lithium batteries is much higher than that of lithium iron phosphate batteries. Assuming that the cycle life of the power battery is about 1,000 times, it can travel a total of 500,000 kilometers.

Considering that the power battery slowly begins to decay in the later stage, we roughly give a 20% discount, that is, 400,000 kilometers. After 400,000 kilometers, the power battery attenuates to 80%. Let's say you drive 40,000 kilometers a year, and you can drive for at least 10 years.

Assuming that a pure electric vehicle is equipped with a lithium iron phosphate battery, the combined range of the NEDC is 300 km, that is, it can travel 300 km when fully charged. Assuming that the cycle life of the power battery is about 2,000 times, it can travel a total of 600,000 kilometers.

The mileage is about 180 kilometers or more, but each model and battery are different, so the mileage can not be completely determined, just a approximate data.

Generally, it is about 300 kilometers, this endurance is still okay, if it is a new car, the endurance may be a little more, to if it has been driven for several years, then the endurance will slowly deteriorate.

It is about 700 kilometers, and the cruising speed of new energy vehicles is still very good, and it is relatively safe to drive.

In fact, it's about 300 kilometers, and sometimes it is written that it is four or five hundred, but in fact it is not possible to go that much.

I bought my own car EU5, which can run more than 500 kilometers on a single charge, and it lasts a long time.

The range of pure electric vehicles is basically around 400-700 kilometers.

The battery on the new energy vehicle is the key to the entire power system, it can provide power for the entire new energy system, but due to the constraints of materials and technology, the battery provides limited mileage, and the battery supports the maximum mileage refers to the maximum mileage of the car in pure electric mode only relying on the power in the battery to support the car.

Precautions for new energy vehicles.

The vehicle should be charged in time during use to avoid the vehicle being stranded due to low power. When using an electric vehicle in winter, try to charge it as soon as possible. Charging the vehicle at any time after each use can achieve better charging performance without the battery temperature being reduced.

Before charging, develop good habits of visual inspection of charging equipment and vehicle charging port inspection to ensure charging safety, and ensure that the use environment is ventilated and dry when charging in winter.

What is the difference between the range of new energy vehicles and ordinary cars? There is a difference of 500 kilometers, but now people do not fully accept the arrival of new energy, because there are two new energy problems that have not yet been solved, one is the field of drive, and the other is the problem of charging.

New energy vehicles should be able to travel 6 to 700 kilometers at a time when fully charged. This is the most energetic process. Of course, unlike the Wuling mini, it is very small, only a few kilometers.

China's Ministry of Industry and Information Technology adopts NEDC (New Standard European Cycle Test) when testing the full mileage resistance of trams, and due to the good test environment, all loads (such as air conditioners, headlights, heated seats, etc.) can work normally However, with the increase in the number of cars in China and road conditions.

The WLTP (World Light Vehicle Test Procedure), developed by Japan, the United States, and the European Union, is much stricter than the NEDC. The test is divided into four parts: low speed, average speed, high speed and ultra-high speed.

The tools and weight of the vehicle (cargo and passengers) were included in the tests. Since the test has been adopted by the United Nations World Forum for Harmonization of Vehicle Standards, it is likely to become the standard for the resistance of new energy vehicles in the future.

The battery capacity will be reduced. Dai Tianolu and Sui Hang's research on the evaluation method for the range of clean electric vehicles at different ambient temperatures shows that ambient temperature can affect the range of electric vehicles. The capacity holding rate of lithium batteries is 60%, 70% to 0%, 55% and 40%, 55%, a%, 10%, 84151;, the capacity retention rate of lithium batteries is 20% 40% to -20% 8451;

As you can see from here, the lower the temperature, the smaller the battery capacity. By analogy, the capacity retention rate of lithium batteries is about 60%, which is less than 7 84451;, so the range of an electric car is less than 7; Of course not, because new energy vehicles have the function of heating the battery at low temperatures, so the battery can always work at the optimal temperature. However, the heating of the battery itself will also reduce the energy of the battery, which will reduce the driving range of the entire vehicle.

How many kilometers of new energy vehicles need to look at the battery parameters of the vehicle, and the general range of lead-acid batteries is about 60 kilometers. The mileage span of lithium battery vehicles ranges from 60-300 kilometers. In addition, factors such as turning on air conditioning, body weight, and battery wear will also shorten the vehicle's driving range.

The following is an introduction to the relevant content: 1. Lithium iron phosphate battery, lithium iron phosphate battery is one of the lithium-ion batteries, due to the abundance of raw materials, so it is relatively cheap, in addition, this battery has high safety, good high temperature performance, high charging and discharging efficiency, and environmental protection, and is mostly used in some pure electric passenger cars, such as JAC IEV4 (cruising range 166km-180km), BYD E6 (cruising range 400km), BAIC E150EV (cruising range 150km), Lifan 620EV (cruising range 200km-252km), etc.; 2. Ternary lithium battery, the biggest advantage of ternary lithium battery is its high energy density, so the volume of the battery will be relatively small, which can effectively reduce the volume of the vehicle, and the battery capacity is large, so that its driving mileage has been improved. Ternary lithium battery is unstable in the case of high temperature, which makes the safety of the battery poor, and the current cost is relatively high.

It is mainly used in the JAC IEV5 (cruising range 166km-180km), Changan Yidong EV, BAIC Shenbao EV and other models; 3. Lithium cobalt oxide battery, lithium cobalt oxide battery can be said to be Tesla's exclusive battery, lithium cobalt oxide battery has the advantages of stable structure, high capacity ratio and high density, which makes its driving ability more prominent, comprehensive performance is better, but the cost is higher, mainly used in Tesla models, the current Tesla models range of 480km-613km.

If I run long distances, I'm worried about battery life.

As the power heart of new energy vehicles, the battery life problem has been a criticism of new energy vehicles, and the most common questions we hear when buying new energy vehicles are none other than the following aspects:

First, once the battery of an electric vehicle is scrapped, it needs to be purchased again, which is basically the same as the value of buying a new car; Second, the mileage of the battery is not enough, once in remote areas or on high speeds, it is difficult to find a charging pile in time for battery life; The third is that the battery charging is relatively slow, which is not as fast as the refueling of fuel vehicles, which will delay more time.

According to the experience of the vast majority of users, we don't really care about the high mileage, because compared to the fuel tank of the fuel car, it is only 50 liters to 80 liters of all the fuel capacity, it is also difficult to achieve a range of 1,000 kilometers, and when it runs to about 400 kilometers, it is already a very good experience to reserve a distance of about 100 kilometers to find a charging pile.

If the cruising range of new energy vehicles is increased to 1,000 kilometers, not to mention the driving distance, how many customers really need such a high mileage demand, only in the case of urban exercise, for most office workers, this is indeed not an important factor worth considering.

If it is for drivers who have independent charging piles or are close to independent charging piles, the amount of cruising range is indeed not in the scope of consideration, and the real consideration of this problem is the driver who does not branch the key to facilitate timely charging.

In addition, when the high mileage can be realized, the accompanying battery life false standard also exists, so that it is impossible to judge the time of the next charge according to the accurate remaining mileage, if this problem cannot be solved, then whether the battery life is 1,000 kilometers or 500 kilometers, then once the charging time is missed, especially for the riders who often have business trips, it will be a very troublesome thing.

Therefore, we also hope that our technical research and development personnel can better do a good job in this aspect of technical research, which can not only become a good selling point, but also save unnecessary trouble for the majority of car friends, so that the sales block can make their own vehicles obtain better sales performance.
