What are the reasons for the frequent spontaneous combustion of new energy vehicles? Is there any wa

In recent years, the oil price has continued to rise, so that the new energy tram into everyone's field of vision, the new energy tram has also brought convenience to the owner to a large extent, saving a lot of fuel costs, but the new energy vehicle is really that good? Why do new energy vehicles frequently spontaneously combust? What are the reasons for the frequent spontaneous combustion of new energy vehicles?

Is there any way to reduce losses? Today we will briefly talk about this problem, I hope it will also be helpful to all car owners.

Traditional fuel vehicles basically do not have this problem, because fuel vehicles are two core components, a gearbox, an engine, and there is no open flame. The fuel tank ignites directly, and spontaneous combustion is almost impossible unless something goes wrong with the circuit. New energy vehicles are different, its core is also two motors and one battery, but everyone knows that the battery is very sensitive to temperature changes.

When the temperature is high, its own electrical energy will be released more thoroughly, to a certain extent, but there is no way to dissipate heat, then there is a possibility of spontaneous combustion.

There is no way to change this problem for the time being, because it is related to the continuous pursuit of low cost by new energy vehicle manufacturers and the lack of research on battery safety and heat dissipation, because the manufacturing cost of new energy vehicles is almost 30% 40%, all of which are concentrated in batteries. To reduce costs, it is natural to start from this aspect. The use of good battery cells and the use of more safety measures to strengthen heat dissipation can indeed improve the safety of the battery to this extent, but this means an increase in cost, if the cost is increased, then the price of the car will inevitably increase, and the price is high, consumers will not necessarily buy, so this is also a dead loop.

In fact, the spontaneous combustion of new energy vehicles is not much, the reason why spontaneous combustion incidents have occurred frequently recently, to a large extent, is also related to the weather, because the recent high temperature has led to the heat dissipation system of new energy vehicles can not operate normally, all will occur spontaneous combustion, usually the owner of the car try not to park the car in the sun exposure, when the car is charging, try to choose the evening, or at night, to a large extent to prevent such a situation from happening.

It is very likely that the waterproof effect of the new energy vehicle is not particularly good, and it may also be a problem with the safety of the vehicle; Don't modify your own vehicle without permission.

The first is the problem of new energy vehicles themselves, and the root cause of most new energy vehicle accidents is because of its battery. Although at present, most plug-in hybrid new energy vehicles and new energy vehicles with gasoline-electric hybrid power vehicles need to be matched with corresponding engines.

The charging gun of new energy vehicles should not be placed at will, and should be locked when it is not working. After the charging gun is inserted into the car, you need to swipe the card first, terminate the charging and swipe the card again.

There are many reasons for spontaneous combustion, such as the aging of battery components, external collisions, as well as hot weather, thermal runaway and high load of the battery, etc., which will cause spontaneous combustion of energy vehicles. However, 60% of energy vehicles are caused by thermal runaway of the battery itself.

The reason why the battery will have thermal runaway is because of the uncontrollable violent exothermic reaction in the cell, that is, the temperature of the battery keeps rising, and finally the battery ** is caused by the high temperature, which eventually leads to the spontaneous combustion of the energy vehicle.

If in the process of fast charging, because the conductivity of the battery is not good, the battery is easy to generate a lot of heat, and the sharp increase in temperature will eventually lead to thermal runaway. If the lithium battery is deformed, the components inside the battery will be damaged, which will also lead to thermal runaway.

There are still many reasons for thermal runaway in energy vehicles, such as fast battery charging, overcharging or less charging, etc., at this time, it is necessary to strengthen the function of heat insulation and heat dissipation, because the internal structure of the battery is different, so it is necessary to add some thermal insulation components to ensure that there will be no thermal runaway inside the battery, even if there is thermal runaway, there is time for passengers to leave the vehicle and protect the personal safety of passengers.

For users of new energy vehicles, there are some things that need to be paid attention to if they want to prevent spontaneous combustion of vehicles. For example, in high temperature weather, it is best not to charge the energy vehicle immediately after being exposed to the sun, because at this time, the energy vehicle will increase the temperature of the battery itself after experiencing high temperature exposure, and if it is charged directly, it is easy to lead to aging and damage to the internal circuit, and in serious cases, there will be thermal runaway.

It is best to use the method of slow charging, because the power of slow charging is relatively low, and the damage to the battery is also minimal, and it can also prevent overcharging, and try to ensure the safety of the internal circuit of the battery, so that there will be no thermal runaway.

The energy car purchased by the owner of Sichuan only after only three days occurred spontaneous combustion, which is actually likely to be caused by the thermal runaway of the battery, after all, it has not experienced the exposure to the sun, so in the charging because of the fast charging, the heat dissipation of the battery is not good, resulting in the temperature rise, it is easy to spontaneously combust, so for the owner of the energy car, it is necessary to choose a battery with good heat dissipation.

At the same time, it is best not to charge immediately, and do not choose fast charging, you can charge slowly without use, and you can use it after it is fully charged, which can not only protect the battery, but also prevent spontaneous combustion of energy vehicles. Although it is more troublesome to charge energy vehicles, for today's society, energy vehicles are a new trend, and they will be very popular in the future.

The main factors of spontaneous combustion of electric vehicles are as follows:

The collision of the outside world caused spontaneous combustion;

The wiring in the battery is short-circuited and causes spontaneous combustion;

The heat dissipation system of the battery fails, unable to dissipate heat, and too much heat stored causes spontaneous combustion;

It is the problem of some electronic control systems related to the battery that causes spontaneous combustion.

For example, the aging of battery components, external collisions, as well as hot weather, thermal runaway and high load of the battery, etc., will cause spontaneous combustion of energy vehicles.

The main reason for the spontaneous combustion of new energy vehicles is the battery, which may occur spontaneously due to the following reasons. The first reason is that the quality of the battery is not good, if the quality of the manufacturer's manufacturing is not good, then it will be more likely to spontaneously combust. The second reason is that the temperature of the battery is too high, for example, in the summer, if the temperature is too high, it may spontaneously combust.

The third reason may be that the battery is damaged, for example, if you accidentally scratch the battery when you pass somewhere, then the battery may spontaneously combust.

Because the battery technology of new energy vehicles is still not particularly perfect, there is still a lot of room for improvement. Therefore, there are some immature new energy vehicle batteries, which may spontaneously combust. Therefore, when we buy these new energy vehicles, we should try to buy some big brands, not those less famous cars, so as to improve safety.

If the temperature is very high in the summer, it may cause the battery to spontaneously combust. Because the battery of an electric vehicle is not a high-temperature resistant thing, if it is in a high-temperature environment for a long time, it may change, which will lead to battery deflagration. So talking about electric cars.

Try not to expose it to the sun, and it is better to park in a shady place. <>

In addition, if the battery is damaged, it may cause it to deflagrate. Now these batteries are basically lithium batteries, and lithium batteries have a feature that they cannot be deformed. If the lithium battery is deformed due to external forces, then it is likely to deflagrate quickly.

For example, if you accidentally rub the battery on the bottom of the pothole, this may also happen. Pure calendar.

After reading it, remember to like + follow + **.

It may be because of improper charging, or because there was a violent impact of the chain of silver, or it is possible that the battery separator of the cherry potato is torn, so it will lead to this phenomenon.

Spontaneous combustion of new energy vehicles can be divided into the following three categories: spontaneous combustion during charging, spontaneous combustion during driving, and spontaneous combustion during static processes.

I think it may be because new energy vehicles use inferior batteries, so the phenomenon of spontaneous combustion occurs.

1. Short circuit caused by vehicle aging.

In the engine compartment of the car has dense circuits and electronic components all over it, with the increase of the age of the car, the engine compartment has been in a state of high temperature and high heat for a long time, and in the long run, it is inevitable that the material outside the line will fall off, which will cause short circuit and leakage of the line in the car, and finally lead to the occurrence of open flame seepage. In addition to the aging circuit, the aging of the oil circuit is more dangerous, due to the use of the vehicle when the stove temperature is high in summer, the engine compartment temperature in the car is higher than usual, and the working temperature of some turbine vehicles can reach 800 degrees, once there is an oil leak, the consequences are unimaginable.

2. Miscellaneous items are placed in the car.

For some men who have a habit of smoking, sometimes they will put the lighter in the car after lighting a cigarette. And some ladies also have perfume and other items in the car. In the summer, the temperature in the cabin can reach up to 90 degrees Celsius, and the direct sunlight is likely to detonate the fire.

In addition to this, there is a similar danger of keeping some mineral water bottles in the car, and we all learned that convex lenses can ignite black paper when we were students. In the same way, if the interior of the car is black and the refraction of water is reflected on the seats, it is very easy to ignite the interior.

3. The parking area is not up to standard.

Some car owners who go to the wild always like to park their cars under trees or in the shade, after all, it is good to enjoy the shade under the big trees, but sometimes they ignore the fact that the vehicle is parked near some dry turf, because the vehicle continues to maintain a high temperature state of heat dissipation after driving. If it encounters a dry environment, it is likely to reach the ignition point. Therefore, I also tell everyone to try to standardize parking when parking to avoid unnecessary trouble.

4. Battery quality problems and inadequate maintenance.

Nowadays, there are a variety of new energy vehicles on the domestic market, but some early technologies are not mature, and some car dealers in order to reduce costs do not inspect the vehicles themselves. In addition, the hot weather is that the battery will thermally runaway, many of which are due to the aging of the battery and therefore generate too much heat, plus the battery is used too frequently, so the battery is punctured separator and the internal short circuit.

5. Short circuit of the line caused by later modification.

In addition to the modification of the shape of the vehicle, many vehicles will choose to modify the high-power audio or decorate the interior and exterior of the body with many colorful and beautiful marquee lights or ambient lights. Such a post-modification is not only more individualized, but also some auto repair shops outside are cheaper than the original configuration or 4S shop installation, but the technology is worrying, and it may lead to a short circuit inside the vehicle line afterwards.

<> "Causes of Spontaneous Combustion of New Energy.

As we all know, the development of new energy vehicles has been more than 10 years, and he has also brought more and more hidden accidents at the same time as development, such as spontaneous combustion of new energy vehicles. So why do new energy vehicles spontaneously combust?

The main reason for the spontaneous combustion of new energy vehicles is related to the structure of the battery itself. For example, the battery is deformed or pierced by sharp objects under the action of external forces such as impact and extrusion, which may cause a short circuit in the positive and negative electrodes of the battery, causing the battery to emit a large amount of smoke and even spontaneous combustion.

Although now new energy vehicles have gradually entered thousands of households, there is still no battery that can permanently maintain its stability, affected by the temperature and environment of the liquid, the stability of the battery is fluctuating and empty. Therefore, there is no technology that can guarantee that the battery is 100% absolutely safe, so car owners must regularly check the battery when using new energy vehicles.

There are more and more incidents of spontaneous combustion of new energy vehicles, and new energy vehicle owners have begun to get rid of the worry that they are driving. New energy vehicles frequently appear such things, because the battery used in new energy vehicles, it still does not change the temperature in essence, which will have a direct impact on the performance of the battery. <>

Traditional fuel vehicles basically do not have this problem, because fuel vehicles are two core components, a gearbox and an engine, there is no open flame, and it is almost impossible to spontaneously ignite when the fuel tank is directly ignited. Unless there is a problem with the circuit, but the new energy vehicle is different, its core is also two motors and a battery, but we all know that the battery is very sensitive to temperature changes, and the temperature is high, and its own electric energy release will be more thoroughHowever, there is no way to guarantee that it may spontaneously combust if the heat dissipation is high to a certain extent. <>

This is also related to the fact that new energy vehicle manufacturers continue to pursue low costs and do not have enough research on battery safety and heat dissipation, because the manufacturing cost of new energy vehicles is almost 30% 40%, all of which are concentrated in the battery. If he wants to reduce costs, he naturally has to start from this aspect, using good battery cells, using more safety measures to strengthen heat dissipation, etc., can indeed improve the safety of the battery to this extent, but this means an increase in cost. Now domestic new energy manufacturers are engaged in new energy, the low-price competition strategy of automobiles is to engage in cost-effective, the first can not be sold too expensive cost, if he does not get effective control, what will he take to make money?

In addition to the fact that new energy vehicle manufacturers have not made enough efforts, it is a technical problem, the core components of new energy vehicles, the battery, which itself is unstable. It is more likely to have problems than the engine fuel tank of fuel vehicles, which is a disadvantage of technology, not simply a problem for new energy vehicle manufacturers, the existing technology has not yet reached the level that can ensure the safe and stable operation of car batteries in any case, which will take time, but manufacturers will definitely not say this thing when selling cars.
