Recently,the country has once again entered its annual large-scale rainy season.Nowadays,there are more and more new energy vehicles on the roads.Compared to fuel vehicles,what precautions should be taken when driving new energy vehicles in heavy rain?
Key points:
Try to avoid going out and wading through water during heavy rain.
I once saw a debate online: "Which has stronger water-crossing capabilities,new energy vehicles or fuel vehicles?"
Netizens who support fuel vehicles believe that new energy vehicles cannot be soaked in water,as it will cause leakage and electric shock,which could not only damage the vehicle but also harm people; Netizens who support new energy vehicles argue that the waterproof level of new energy vehicle batteries is very high,generally reaching the IP67 level,so a bit of water accumulation is nothing,while fuel vehicles will "break down" as soon as water enters the exhaust pipe.
So,who is right?
First,let's state the conclusion: New energy vehicles are also cars,not submarines.It is still necessary to try to avoid going out and wading through water during heavy rain.

Traditional fuel vehicles,because the engine is divided into four strokes: intake,compression,power,and exhaust,once water enters the engine's intake port,it may pour into the engine and cause the engine to stall.The wading depth of most general sedan models is between 200 to 300 millimeters,while SUV models are slightly higher than sedans.Some models can achieve a wading depth of 300 to 400 millimeters,and some professional off-road vehicles (without professional wading modifications) can reach a wading depth of more than 400 millimeters.
In contrast,due to the greater emphasis on sealing performance in the design of the "three-electric systems" (battery,motor,and electronic control),the probability of the system being submerged in water is very low,and the wading depth of many new energy vehicles is higher than that of traditional fuel vehicles.For example,the official wading depth of the mainstream models of a domestic brand new energy vehicle is 400 to 450 millimeters.
What is the "new energy vehicle battery waterproof grade IP67" mentioned earlier?
IP stands for Ingress Protection Rating,which is a protection level of an interface against solid particles and liquids.
The first digit represents the protection level against solid particles,which can be understood as dustproof,ranging from 0 to 6.The larger the number,the higher the dustproof level,meaning it can prevent finer dust particles.
The second digit represents the protection level against liquids,also known as waterproofing,ranging from 0 to 8.The larger the number,the higher the waterproof level,indicating the level of protection from vertical water droplets to underwater pressure.
It can be seen that the protection level of IP67 is actually quite high,which can completely prevent the intrusion of foreign objects and dust,and ensure integrity under short-term water immersion.
At this point,some friends may think: "Look,my car's waterproof level is so high,can I be a 'white streak in the waves'?" The idea is very rich,but the reality is very bony.
Driving during heavy rain,passing through waterlogged roads,and normal vehicle wear and tear can make the situation very complicated.Moreover,the road conditions in the waterlogged area are unclear,and rash wading may easily lead to deep water areas,resulting in more serious accidents or even casualties.
The specific problems that may be encountered mainly include:1
Puddles can affect visibility and may cause damage to the chassis and battery.
When urban roads are flooded,the water is usually very turbid,and even if the water is clear,it can severely affect the naked eye's ability to observe the road conditions.In this situation,there may be potholes,debris,etc.,on the road.If the chassis or battery is run over or scraped,it is likely to have serious consequences.
2
Water may enter the car through gaps.
When the vehicle's wading depth is too high,although the three-electric systems are not affected and can continue to operate,water may enter the car through gaps,soaking the mats,seats,etc.If it is not found and dealt with in time,it may lead to problems such as mold,odor,and accelerated wear.
3
High-tech accessories may be damaged.
Now many new energy vehicles will use a large number of high-tech products,such as various sensors,cameras,radars all over the body,these accessories may also be soaked or impacted by water during wading,leading to damage.

(The fourth point is incomplete,please provide the full text for translation.)"Water accumulation areas" appear inside the vehicle,leading to rusting.
After wading through water,due to the irregular shape of the vehicle body,there may be "water accumulation areas" in some parts.At the same time,due to poor ventilation inside the car,the water cannot evaporate for a long time,and the metal parts of the car are prone to rusting,which affects the service life.
Therefore,even if you drive a new energy vehicle,do not easily enter the waterlogged sections.
Can new energy vehicles be charged in rainy days?
According to the new national standard,the protection level of the charging gun interface before insertion is IP54,and after insertion,it is IP55.As long as the inside of the charging gun and the charging port are dry,you can charge with confidence.
However,many car owners in the suburbs like to use long extension cords to charge their cars,which is very dangerous in rainy days,and must be paid attention to.

In addition,the charging pile may have water leakage due to improper operation,causing the sealing ring to loosen and deform.In addition to rainy days,snow days will also have similar risks caused by snow accumulation.Therefore,it is recommended that everyone operate according to the specifications when plugging and unplugging the charging gun.If conditions permit,try to choose a non-open charging pile for charging in rainy and snowy weather.
New energy vehicles encounter heavy rain or waterlogged sectionsWhat Should Be Done
Once again,it is emphasized that the first priority is to avoid driving in adverse weather conditions.If you haven't left the house,it's best not to go out at all,as nothing is more important than one's own safety.
However,if you encounter adverse weather conditions while driving,here are a few suggestions:
1.Find a high ground with shelter to park
You can look for a location with high ground and shelter to park your car,then go to nearby large and sturdy buildings such as shopping malls or hotels to take shelter from the rain,and continue driving after the weather improves.
2.Observe thoroughly before entering flooded areas
Before entering flooded areas with your vehicle,it is essential to make thorough observations,paying attention to the depth of the water,whether the road surface is solid,and whether there are any foreign objects or obstacles in the driving route.
3.(Note: The original text was cut off,so the third point is not provided.)Understanding the Water Depth for Family Cars in Advance
The issue of water depth for family cars is not a fixed value because the ground clearance of different vehicles varies.Generally,the water depth should not exceed the radius of the tire,which means the water should not cover the car logo in the middle of the wheel,which is generally not dangerous.Conversely,if the water has covered the car logo in the middle of the wheel,it is best not to take the risk of wading through the water.

Try to maintain a low speed when driving into the waterlogged section
When driving into a waterlogged section,try to maintain a low speed and do not drive too fast.Keep a constant speed below 30 kilometers per hour.At the same time,according to the observation before driving in,maintain a straight line and pass through in one go.Do not stop,shift gears,or make sudden steering during the process of wading through water.
What to do when the car is flooded
1
How to save yourselfPull Over and Turn Off the Engine
If your vehicle is about to be submerged,it is best to pull over and turn off the engine.Do not start a car that has been submerged in water,as it may cause damage.
2
Observe Road Conditions and Evacuate in Time
Get out of the vehicle and walk to a safe place in a timely manner,but do not suddenly jump out of the car.Check the depth of the water and whether the road surface is flat and solid,and look for any foreign objects to prevent falling and getting injured when getting out of the car.
3
If the Car Door Cannot Be Opened,Do Not Panic and Try to Break the Glass
If the car door cannot be opened due to water ingress causing a failure in the vehicle's electrical system,do not panic.Using a sharp object or an emergency escape hammer to break the glass will greatly increase the chances of escape.It is best to keep an emergency escape hammer in the car at all times.
4
Climb onto the Roof of the Car for Temporary ShelterWhen a car is submerged in water,as long as the doors and windows remain closed,it generally will not sink immediately.At this time,it is necessary to stay calm,wait for an opportunity to escape,and you can climb onto the roof of the car for temporary shelter,waiting for rescue.
What to do after a car has waded through water or been flooded:
1.Timely inspection and repair at the 4S store
After the weather improves,go to a 4S store or an auto repair shop to have the vehicle inspected.If there are parts of the vehicle that have been flooded,they need to be dealt with promptly.
2.Contact the insurance company in a safe situation as soon as possible
If the car has been flooded,in a safe situation,notify the insurance company of your vehicle as soon as possible.Many insurance companies offer free roadside assistance services with the insurance policy.There will be a professional roadside assistance company to transport the car to the repair shop.Do not move the vehicle by yourself,as it may cause secondary damage.
3.Do not forcibly start the engine when the vehicle is submerged in water.
Forcing the engine to start in such a situation can lead to damage to the vehicle,and the insurance company may refuse to compensate.
