Why is the range of joint venture pure electric vehicles generally short?

The cruising range of the joint venture brand pure electric vehicle can be regarded as excellent if it can exceed 300km, but on the side of the independent brand, the cruising range of 400km is the start, and the excellent can already reach the cruising range of 500km, which is more than 1 times that of the joint venture brand。As far as I know, many owners of pure electric vehicles have range anxiety, and the range of joint venture brand pure electric vehicles is so small, they are destined to be unacceptable to consumers. Don't look at the current domestic pure electric vehicle market, it is the independent brand that plays the leading role, but when it comes to technology accumulation, the joint venture brand is not weak at all

For example, Volkswagen developed the first pure electric car as early as 1972; There is also Nissan, whose Leaf is sold all over the world. It can be said that most of the joint venture brands have better three-electric technology than their own brands, which makes them develop pure electric vehiclesThe actual cruising range will not differ much from the cruising range advertised by the manufacturer. There is still a long way to go for independent brands in the three electric fields, and the phenomenon of false standards is very seriousTherefore, it will give people the feeling that the mileage of the joint venture brand pure electric vehicle is small, and the mileage of the independent brand pure electric vehicle is high.

Some friends may want to ask, isn't there a corresponding cruising range test in China? Aren't false labels afraid of revealing stuffing? I'm really not afraid! China's certification of the range of electric vehicles is based on the standard GB T

This standard is mainly based on the European NEDC standard.

However, the NEDC is very controversial at present, due to the early birth of the standard, coupled with the small test mileage and short timeThe technical requirements for the three electric vehicles are not so high, and it is easy for independent brands to measure a good endurance result, but the road conditions in reality are much more complicated, so the actual mileage of these models will be greatly reduced. As I mentioned earlier, joint venture brands currently dominate the domestic gasoline vehicle market, and the profit is the best, unlike many independent brands, which will not survive without switching to the field of pure electric vehiclesTherefore, the joint venture brand is not concerned about the research and development of pure electric vehicles.

If you want to have a high mileage for a joint venture car, you need a lot of technology and capital.

The current EV market is already weak and problematic.

Because the technology of electric vehicles is not very mature now, this is the main reason.

Because the electric car has a relatively short battery life, it will run out of power after driving for a while.

Because electric cars have a limited amount of stored power, they can't go that far.

Because the current level of science and technology is not particularly mature, the battery life is not very good.

This is because there are big mistakes in the range of such cars.

The biggest reason is probably because these cars are not very perfect, so the mileage is relatively short.

Hello, in response to your question, is it better to buy an electric car with a long battery life or a short one. At present, the development of electric vehicles shows that the longer the battery life, the better, for the following reasons: 1. Although there are more and more charging piles now, it is obviously not able to meet the gradually large family of electric vehicles, so the charging problem has become the biggest problem for electric vehicles.

Sometimes I found the charging pile on the map, calculated the remaining power, and rushed all the way over, and found that they were all dead piles, and the feeling was the same as wanting to jump off the building. Sometimes, fuel vehicles also seize the charging position of electric vehicles, and see that the pile cannot be charged. Therefore, the battery life of electric vehicles is short, and it is possible that they will not be charged halfway and lie on their stomachs, while electric vehicles with ultra-large endurance do not have to worry about this.

If the battery life is short, you can't afford to wait. 3. Air conditioners in winter and summer will consume more power and shorten the mileage. Electric car owners know that if the air conditioner is lowered by a few degrees in summer, the range figure will come down immediately.

In winter, the air conditioner is turned up a few degrees, and the cruising range is immediately shortened. It's shocking to watch. Therefore, the battery life is longer, and the heart is more steady.

4. This is also the most critical, in the winter when the temperature is lower, the battery activity will be reduced, and the cruising range will be shortened. Based on the above factors, the more mileage, the better, the more battery power remains, the more relaxed the heart, otherwise you will worry about lying in the nest at any time. Hope mine can help you

<> "Due to the intensification of environmental pollution and the increase in energy conservation and emission reduction requirements, both the state and the automotive industry are paying more and more attention to the development prospects of pure electric vehicles.

With the development and expansion of cities and the continuous increase in housing prices, more and more people are commuting long distances, and these office workers have a kind of "range anxiety" about this, and generally believe that the range of electric vehicles cannot meet daily needs. Electric vehicles have a relatively short range compared to traditional cars, so what are the factors that limit the range of electric vehicles?

As with conventional cars, factors such as the external driving conditions of the vehicle, the rolling resistance coefficient, the air resistance coefficient, the mechanical transmission efficiency and the quality of the vehicle have the same driving range for electric vehicles as those of traditional cars. Other factors include the performance of the traction battery, the energy consumption of the auxiliary system, the braking energy feedback system, the ambient temperature and the battery loss.

1.Power battery performance.

Power battery performance refers to the rated capacity, energy density, etc. Different batteries have different performance, resulting in different ranges. If lithium-ion batteries are used, the battery quality can be reduced by 2 3, and the cruising range can be increased by more than 15%, that is to say, the more batteries, the higher the battery energy density, the longer the cruising range, and the higher the cost.

2.Energy consumption of the auxiliary system.

Like motors, lighting, heating and cooling air conditioners all need to consume energy, among which the power consumption of air conditioners is particularly large, and experiments show that the whole process of air conditioning will reduce the cruising range by about 1 4. Therefore, when we choose these components, we should try to choose less energy, which is conducive to increasing the range of electric vehicles. As far as the motor is concerned, the single motor has small power, slow speed and long mileage, and the dual motor has high power, fast speed and short mileage, which has become a problem that many people are more entangled.

3.Brake energy feedback system.

In other words, electric vehicles convert the energy during braking into electrical energy and store it in the battery, reducing energy loss. 15%-20% of the energy, but if there is no braking energy system, the cruising range will decrease.

4.Ambient temperature.

The energy emitted by the battery pack at different temperatures is different, and the range is also different. For example, lithium-ion can release 2 3 more energy in winter than in summer, and the temperature has an impact on the efficiency of all parts of the vehicle.

5.Battery wear.

If the battery is well maintained, the battery life will only decrease by 20% within five years.

As a rookie in the automotive industry, pure electric vehicles involve some new fields and face many problems, which cannot be popularized. We should use pure electric vehicles scientifically, so that the manufacturers of automobile start-up vehicles have standardized restrictions, more energy-saving and environmentally friendly, and accelerate the arrival of the era of pure electric vehicles.

When the battery life is no longer affected by subjective and objective factors, as long as you have enough battery capacity, can you completely solve the range anxiety?

In fact, according to the current stage of battery technology development route, many consumers do not expect the unlimited increase of battery capacity to achieve the requirements of large power and high battery life. This is due to the fact that the energy density of the battery is much smaller than that of gasoline, so if the battery capacity is simply increased, the battery will take up more space in the vehicle and the weight of the vehicle will increase significantly. When the weight of the battery reaches a certain level, one-third of the output power is used to offset the negative impact of the battery component, which is obviously a lot of useless work.

In addition, even if the current battery technology is broken, the cruising range of electric vehicles exceeds 800 kilometers, or even 1000 kilometers, and the ultra-high-capacity battery is loaded with it, so the charging time will be greatly increased. After all, the speed of replenishment of energy is actually constant, which will also reduce the efficiency of travel, and the larger the capacity, the longer the charging time is bound to be.

We are coming back to the bridge to answer the question of range anxiety, not only about how far the electric car itself can travel, but also about the convenience and speed of charging at the moment.

Zero-emission mobility.

Very intuitive, very direct we take the fuel car to illustrate, at present, look at the family fuel car, a full tank of fuel can also run to 500 or 600 kilometers, the reason why the fuel car has no mileage worry, because we can easily find a gas station nearby, and it takes less than 10 minutes to fill up a tank of fuel.

However, at present, the supporting facilities of charging piles have not been able to keep up with the progress of electric vehicle development, and the failure rate is very high, even in the fast charging mode, the charging time often takes more than an hour, which greatly reduces the travel efficiency, which is the root cause of everyone's anxiety.

Therefore, if you want to solve range anxiety, the most important thing is not only to increase the range to a reasonable value, but also to increase the number of charging piles and battery storage technology, and to improve the charging efficiency of Minlahui.

1.Battery: Whether it's an electric car or a 4WD, it only needs electricity to provide power.

Basically, a general principle is followed: all other things being equal, the higher the battery capacity, the longer the battery life per cell will naturally be. For electric vehicles, the battery is like the fuel tank of a traditional combustion vehicle.

The larger the car's fuel tank, the more fuel it will hold, and it will naturally go further.

2.Electrical Control:

In addition to the performance and quality of the battery itself, electronic control is also a crucial factor related to the range of electric vehicles. Electronic control, which is often referred to as BMS (battery management system), is responsible for the safety monitoring and effective management of electric vehicle power batteries, so that the power battery can work in the best state, improve the efficiency and reliability of the power battery, and prolong its service life.

3.Motor: It is also a tool that converts energy (fuel) into power.

The position of the electric motor in an electric vehicle is almost the same as that of the engine in a conventional combustion vehicle. Many people think that the motor is just a tool to drive the car, and it is only related to the performance indicators such as the acceleration and ultimate speed of the car, and has nothing to do with the cruising range.

4.Weight: Pushing a self-driving car under 50 kilograms to walk home, and pushing a car weighing more than 2,000 kilograms to walk home is definitely more strenuous for the latter.

Therefore, whether it is a traditional fuel vehicle or an electric vehicle, the quality factor has a great impact on the range of the car. In particular, the power battery, which is a vital energy storage device in electric vehicles, is the "main culprit" that causes the vehicle to be overweight.

5.Wind resistance: Wind resistance, as the name suggests, is the resistance from the air that the car is subjected to when driving.

Although we often see the words "drag coefficient" and "aerodynamics" in the brief introduction of sports cars or concept cars, in fact, wind resistance is not only related to the acceleration performance and ultimate speed of the car, it is also closely related to our daily private cars.

1.Battery: Whether it is an electric car or a four-wheel drive vehicle, as long as it is electrically driven, it follows a universal principle:

All other things being equal, the higher the battery capacity, the longer the range per trip. For electric vehicles, the battery is like the fuel tank of a traditional combustion vehicle. The bigger the tank, the more oil it contains, and the farther it will naturally go.

2.Electrical control erection Nachang:

In addition to the performance and quality of the battery itself, electronic control is also an important factor affecting the range of electric vehicles. Electronic control, which is often referred to as BMS (battery management system), is responsible for the safety monitoring and effective management of the power battery of electric vehicles, so that the power battery works in the best state, improves the efficiency and reliability of the power battery, and prolongs its service life.

3.Motor: It is also a tool that converts energy (fuel) into power.

The status of the electric motor in the electric surplus car is probably equivalent to the status of the engine in the traditional fuel vehicle. Many people think that the motor is just a tool to drive the vehicle, and only affects the performance indicators such as the speed and speed limit of the vehicle, and has nothing to do with the cruising range.

4.Weight: Pushing a bicycle weighing less than 50kg to walk home, and pushing a car weighing more than 2000kg to walk home is definitely more strenuous for the latter.

Therefore, whether it is a traditional fuel vehicle or an electric vehicle, the quality factor greatly affects the endurance of the vehicle. In particular, the power battery, an important energy storage device in electric vehicles, is the "main culprit" of overweight vehicles.

5.Wind resistance: Wind resistance, as the name suggests, is the resistance of the air from the air when the vehicle is moving.

Although we often see words like "drag coefficient" and "aerodynamics" in the introduction of sports cars or concept cars, in fact, drag affects not only the acceleration performance and top speed of the vehicle, but also our daily private cars.
