The torrential rain and flood in the south are menacing, and the precipitation in Changsha in 1 hour is about equal to 54 West Lakes, and the video of "M9 when the boat drives in the Changsha rainstorm" is also spreading on major video platforms and major WeChat groups.
The streets have become big rivers and the urban areas have become oceans, and some new energy vehicle owners in the flooded areas of the south have raised questions: Is the online video hype? If my new energy vehicle also drives like this, will it leak electricity, and is there any danger to my life? Many new energy vehicle product manuals and official websites do not announce the relevant wading parameters such as the wading depth of the vehicle, how to save yourself in the rainstorm and flood, who should I ask?
Regarding dozens of mainstream new energy vehicles on the market, the reporter of "Daily Economic News" (hereinafter referred to as "every reporter") launched a survey on the wading capacity and asked car manufacturers one by one.
Should I abandon my car or take the risk of wading in the water due to heavy rain?
Some southern car owners who continue to pay attention to heavy rain and flooding have checked the vehicle product manual and the official website of the car dealer, and found that they have not disclosed relevant parameters such as the depth of wading that can be waded, and they still do not know how much their vehicle is flooded and is at risk and cannot be driven.
A car owner said that although he would not take the initiative to take the initiative to wade into the water, in case of a sudden rainstorm and flood while driving, there is standing water in front and floods rushing in the rear.
According to people in the automotive industry, there are no mandatory regulations on whether to mark the wading parameters of the car on the product manual, but because it is related to the safety of the life and property of vehicle users, it is expected that the relevant regulations can be improved in the future.
Many southern new energy vehicle owners said that in the summer of the heavy rain constantly "nostalgic" to the earth, I don't know where to learn about the wading parameters of new energy vehicles, and I don't know which situations can get insurance compensation after electric new energy vehicles are soaked in water, and which cases belong to the driver's responsibility and cannot be claimed.
Compared with fuel vehicles, the wading ability of new energy vehicles can be compared by wading depth and wading time. Before understanding the wading capabilities of each model, let's first understand an important wading parameter: IP.
IP是Ingress Protection Rating的缩写
(1) IP refers to the dustproof and waterproof standard, and the minimum waterproof level of general new energy vehicles is IP65.
(2) Among them, the second number after IP represents the protection level for liquids, which is often said to be waterproof, the range is 0-8, the larger the number, the higher the waterproof level, and "7" means that it can be soaked in water for a short time without damage.
New energy vehicles wading ability competition
The reporter of "Daily Economic News" conducted an investigation on the wading ability of mainstream new energy models on the market, and exclusively presented you with a treasure book of wading, let's take a look at how they "cross the sea with eight immortals"——

BYD did not reply to the wading depth information of the Qin, Han and Yuan series models.
Cialis said that it did not have the wading data of the M7.
FAW-Volkswagen also said it did not have wading depth data for the ID.4.
Tesla did not respond to the data on the Model 3 and Model Y.
New energy vehicles wading in the water, the top ten problems that car owners are concerned about
1. Are new energy vehicles afraid of flooding?
At present, many electric vehicles use IP67, which is the international protection class (IP) standard, which has a high level of safety when wading in the water during heavy rains.
2. Is it safe to charge in rainy days?
Charging in rainy days is safe, but there are some operating specifications and safety measures to be aware of. For example, check whether there is water or foreign matter in the connector interface on the pile side and the car side; If you encounter a charging pile that has been flooded, you should stay away; When the ground is heavily waterlogged or rainy, avoid charging in the open air.
3. Is the "motor and electronic control" of new energy vehicles absolutely waterproof?
Motor, electronic control and other modules are enclosed by centralized internal water cooling design, which further eliminates the penetration of external liquids, but it is not absolutely waterproof, and should not be soaked in water for a long time.
4. Is the passenger compartment of a new energy vehicle waterproof?
The passenger compartment of a new energy vehicle is basically not waterproof. Many new energy vehicles are covered with sensors, cables, and various parts under the interior floor, and once the passenger compartment is flooded, it will cause a short circuit in these parts.
5. Is the wading ability of plug-in hybrid and extended-range new energy vehicles the same as that of pure electric vehicles?
In addition, plug-in hybrid and extended-range hybrid vehicles have engines and transmissions, so if the wading height exceeds the air intake, the engine may absorb water, causing it to stall or fail to start again.
6. How to drive safely when new energy vehicles are wading in water?
The first thing to know is the maximum safe wading depth of the vehicle, which is usually recommended not to exceed the center point of the hub and not to exceed 2/3 of the hub. Avoid intersecting with oncoming vehicles to avoid sudden increases in water level. Check the underwater road conditions before wading to make sure there are no obstacles or deep pits. After wading through water, check the vehicle's electrical system and mechanical parts to ensure that no water enters the vehicle or battery compartment, and avoid charging it immediately to prevent short circuits.
7. How to deal with new energy vehicles after wading and breaking down?
After breaking down, the first priority is to ensure personal safety, quickly leave the vehicle and move to safety. Avoid attempting a second start, as this may cause an internal short circuit or fire. The insurance company or professional rescue team should then be contacted. After the vehicle is towed to a safe location, it needs to be thoroughly inspected by professional maintenance personnel, especially the battery, motor and electronic control system.
8. What should I do if the underground garage is flooded?
You need to contact professional rescue and insurance companies immediately and follow their instructions for follow-up. Once the water has receded, a full inspection is carried out by a professional maintenance personnel, especially the battery and electrical system, and to ensure that the vehicle is thoroughly dry.
9. What conditions can a new energy vehicle be re-ignited after being soaked in water for a long time?
Before re-ignition, ensure that it has been thoroughly inspected and dried by a professional service person, especially for batteries and electrical systems. Insulation tests are performed to confirm that the resistance value meets safety standards, and the battery tightness is checked to ensure that no water has penetrated. At the same time, the high-voltage system and other components need to be confirmed to be free of direct damage. In the absence of the risk of leakage and other safety hazards, follow the manufacturer's guidance and the insurance claims process.
10. If the car is blistered, will the insurance pay for it? What special circumstances are not covered?
Liao Jianxun, a senior partner of Guangdong Guoding Law Firm and a well-known public interest lawyer, told reporters: "After the comprehensive reform of car insurance in September 2020, wading insurance has been classified as car damage insurance. ”
On June 26, a relevant staff member of Ping An of China said in an interview with reporters: "After the vehicle is soaked in water, it is recommended to report the case as soon as possible within 48 hours." As long as the insured vehicle has purchased car damage insurance, according to the terms of the insurance contract, the vehicle can go through the insurance claim in the event of natural disasters and accidents. ”
Regarding "whether the insurance company will refuse to pay compensation if the vehicle is turned off and started a second time due to water accumulation, lawyer Liao Jianxun said: "If the vehicle is unable to drive normally due to water accumulation during driving, it is recommended that the owner do not start the second time to prevent secondary damage to the engine and insurance disputes, and it is difficult to prove that it is 'unintentional'." ”

Reporter's Notes | For the sake of passenger safety, car dealers should not be silent
Under the ravages of heavy rain in the south, new energy vehicle owners will be confused about how to wade in the water when they encounter floods, which highlights a problem that cannot be ignored: due to the unclear wading performance of some vehicles, car owners do not know who to ask to survive in the rainstorm.
Trams are completely different from fuel vehicles, and the judgment of fuel vehicles is based on the height of the exhaust pipe.
Although some models, such as the Yangwang U8 and Li L9, have shown commendable wading ability, there are still many brands that are silent about their wading performance, avoiding a key safety issue.
In the face of extreme weather, the car is not only a means of transportation, but also a solid barrier to protect life. The lack of vital safety information such as wading depth in the vehicle is not only related to the safety of property, but also directly related to the life safety of the people in the vehicle. At the critical juncture of surviving in a rainstorm, car owners urgently need clear and reliable guidance, rather than blindly moving forward in the unknown risks.
