Is there a risk of electric shock when driving an electric car on a rainy day?

Safe and secureFirst of all, we can be very sure of the problem of this little partner, under normal circumstances, there is no possibility of danger in driving a pure electric vehicle on a rainy day. The state has strict safety inspection and certification for each pure electric vehicle officially sold on the market, and engineers will also fully consider the actual use of users in the research and development stage, such as the waterproof performance of the charging interface, the waterproof performance of the battery pack, etc. <>

Be cautious when wading into waterFor some cities, especially in the extreme rainy season, urban waterlogging is a thing we have to face. In fact, not only pure electric vehicles, fuel vehicles also have such problems. Therefore, when we need to wade in some cities in the face of waterlogging, we also need to pay more attention and be cautious, judge the water depth and route, and try to avoid wading.

The above is about the popularization of some small knowledge about the use of pure electric vehicles in rainy days, in fact, pure electric vehicles will not have so many dangers in normal use, and they can be used with confidence.

Among all electric vehicle manufacturers, BAIC BJEV's BMS battery management system has a very large safety scope reserved for application links and the system is stable.

Before the electric vehicle leaves the factory, it will go through the test of high temperature resistance, low temperature resistance, acid and alkali resistance, and water resistance, and the power battery pack on the chassis of the vehicle can protect the battery from damage with a protective layer on the outside. <>

When the fuel vehicle wades in the water, when the water does not pass through the intake and exhaust pipes of the car, the engine will stop working, and the car will "lie down". However, electric vehicles do not have intake and exhaust systems, and even if the water does not reach the front machine cover, they can drive normally. "BMS (i.e., battery management system) mainly provides high-voltage electric shock protection, vehicle collision power-off protection, high-voltage component waterproof protection, high-voltage leakage insulation protection, etc.

Although there are differences in the function of BMS between car brands, the purpose is to protect the battery state at all times.

No, electric cars have their own way of driving, and generally not.

There will be a danger that will arise, and it is very dangerous because of the leakage of your electricity bill.

I don't think there's a bit of truth to this statement, because I think it could really be electrocuted.

I don't think so, if there's a risk of electric shock, it's okay, it's terrible.

This is unlikely, but there are still some of them, after all, electric cars will be considered.

I don't think there's any need to worry about that, I'm sure there will be security.

There will definitely be no risk of electric shock, what does driving an electric car on a rainy day have to do with electric shock?

I think it's because of a lot of reasons, don't you think so?

There are some differences between an electric electric vehicle and a home electric shock.

First of all, the voltage of a pure electric vehicle is usually much higher than that of a home circuit, generally above 300V, while the voltage of a home circuit is usually 220V. As a result, electric shocks from BEVs can be stronger and more dangerous.

Secondly, the battery system and electrical system of pure electric vehicles are professionally designed and manufactured, with multiple protection measures, such as bypass current protection, over-voltage protection, over-temperature protection, etc., to ensure safety. Home circuits may not have these protections and are prone to electric shock accidents.

Finally, the battery system and electrical system of pure electric vehicles have been rigorously tested and certified to meet national and industry standards, while home circuits may have some safety hazards, such as old wires, leakage and other problems.

Therefore, while electric shocks in pure electric vehicles and electric shocks in the home are both electric shock accidents, electric shocks in pure electric vehicles can be more dangerous and require special attention to safety.

Home 220V AC, electric electric is direct current electric electric shock is under the conditions that meet the conditions may be electrocuted, but special specific conditions.

Electric vehicles are driven by high-voltage power systems, so companies will pay special attention to the high-voltage safety of electric vehicles when developing and designing. Good enterprise high-voltage system parts, high-voltage wiring harnesses, high-voltage connectors, etc. are required to meet the IP67 waterproof and dustproof level (no water enters after soaking in 1 meter deep water for 30min, and all functions are normal).

In addition, before the electric vehicle is listed, it needs to pass the vehicle wading test, and the wading depth is 100mm, 300mm, and the company with high requirements for itself even requires more than 400mm (quietly revealed, MG EZ wading depth is 430mm). 400mm is just a static water depth, and the echo caused by the car in the narrow wading pool will actually be much higher than this value.

In addition, the high-voltage safety of electric vehicles requires real-time detection of high-voltage system insulation, battery temperature, etc. If there is any abnormality, the protection will be turned on in advance, and the security is guaranteed. In addition, many traditional rubber trucks may experience water ingress into the engine or exhaust pipe.

Millions of car purchase subsidies.

At present, the voltage of pure electric vehicles is 300-400V, and the voltage of electric buses is 580-600V. When exposed to 220V voltage, the average human body resistance is 1900, and when the contact voltage is 380V, the human body resistance drops to 1200.

In this way, according to Ohm's law, i=u r, the current of pure electric vehicle leakage through the human body is about 300mA, and the current of electric bus leakage through the human body is about 500mA.

Under normal circumstances, the safe current that the human body can withstand is 10mA, and the current of 1mA is felt when it passes through the human body, and it is difficult for the human body to get rid of more than 25mA, and 50mA will cause cardiac arrest and respiratory paralysis. Therefore, although the electric vehicles we usually drive are very safe, in case of water leakage, it will really electrocute people!

The seasons change, and now the southern part of our country is about to usher in the rainy season. As soon as the rainy season arrives, many car owners and friends will have to find a suitable parking spot for their cars, because we all know that fuel vehicles cannot be immersed in water. So, will an electric car be electrocuted when it crosses the water?

Generally speaking, the pure electric vehicles on the market will reach the IP67 protection level. The so-called IP protection level, the first number refers to the solid-state protection level, which indicates the protection from large particles of foreign matter to dust; The second number indicates the degree of protection against liquids, which indicates protection from vertical water droplets to underwater pressure. The higher the IP protection number, the stronger the protection of the natural vehicle.

Therefore, the current protection level of pure electric vehicles can basically meet the standard.

In other words, as long as it is a general waterway, the safety of pure electric vehicles will not be lost to fuel vehicles. Even to some extent, the waterproof safety of pure electric vehicles is better than that of fuel vehicles. This is because the battery pack of pure electric vehicles is closed, and the engine compartment of fuel vehicles is not a closed design, so the safety of pure electric vehicles is naturally better than that of fuel vehicles.

Finally, we usually need to pay attention to wading problems when driving pure electric vehicles, and if the water level is too high, we still choose to take a detour.

Electric vehicles are powered by electrical energy**, and because of the characteristics of electric vehicles, when people think of an electric vehicle crash, they usually think about whether the battery will leak or be more dangerous. In people's subconscious, electric vehicles are also the same as electronic products such as mobile phones and computers, and it is safer to stay away from leakage. But then again, the environment in which a vehicle is used as a means of transportation is very complexFor electric vehicles, from the leakage and above, it is more dangerous than leakage.

Electric vehicles are protected from leakage in terms of leakage, so when leakage occurs, the power supply will be cut off to ensure safety, but for the first time, it is much more dangerous, mainly when the car collides, due to the action of external forces, the lithium battery monomer and battery pack are deformed, and the relative displacement of different parts of the battery itself occurs, resulting in the battery separator being torn and internal short circuit; Flammable electrolyte leaks eventually trigger**.

When the battery is collided, the battery will cause the most serious puncture damage, and it may insert the conductor into the battery body, causing a direct short circuit between the positive and negative electrodes. Compared with leakage, the heat generated during the puncture process caused by battery collision is more violent, and the probability of thermal runaway is higher. Moreover, it is uncontrollable, and all kinds of electrical appliances in the car and the interior of the vehicle will form a kind of combustion situation in the future, which is directly caused by the fact that it is difficult to extinguish.

In addition, from the material of the battery, once the negative electrode material of the battery encounters the air, it is only a few seconds from the first to the deflagration. And ** is uncontrollable, and the danger is more serious.

I think it's dangerous, but it's still leaking electricity in comparison.

I think it's definitely more dangerous to leak electricity, because it can hurt people.

I feel that both of these are quite dangerous, mainly because the leakage is more dangerous.

I think it's all quite dangerous, ** it's more dangerous.

After the collision of the electric car, I think the leakage and ** are quite dangerous.

This is very dangerous, depending on the specific form which is big. Too cruel.

I think both of these are very dangerous and can cause injury or death.

I think leakage is the same danger as **, so you must pay attention to it!

I think it's definitely more dangerous, because then the electricity happens.

I think it's more dangerous for these.
