Can New Energy Vehicles Still Drive When Submerged in Water?

New energy vehicles can still drive when submerged in water. Here are the relevant details: 1. Battery Pack Protection Level: The key components of new energy vehicles are the battery, motor, and electronic control system. Their power comes from the battery pack, which is designed for automotive use and thus has a higher protection level than ordinary batteries. Generally, the power battery packs of pure electric vehicles meet the IP67 standard, meaning they can withstand submersion in 1-meter-deep water for about half an hour without issues, though prolonged exposure poses some risks. 2. New Energy Vehicles: New energy vehicles refer to automobiles that use unconventional vehicle fuels as power sources (or conventional vehicle fuels with new on-board power devices), integrating advanced technologies in vehicle power control and driving systems, resulting in vehicles with advanced technical principles, new technologies, and innovative structures.

My neighbor's electric car got flooded last month, it was really scary! Never attempt to start it forcefully—high-voltage batteries can short-circuit and self-ignite when exposed to water. I once saw a car go from smoking to completely burned out in just five minutes. The first thing to do after flooding is to immediately lock the car, cut the power, move to higher ground away from the vehicle, and then call for rescue. Cars with water levels deep enough to reach the battery compartment are best written off—even if repaired, they often develop hidden issues, and water-damaged motor controllers will eventually fail. Don’t feel sorry for the car—it can leak electricity when submerged, and your life is far more important than the car!

Whether an electric vehicle can move after being submerged in water depends on the water level and duration. If the water just reaches the chassis, disconnecting the auxiliary battery and waiting for a tow truck might save it. However, if the water reaches the seat level, it's basically totaled—once the battery pack gets wet, it's like dropping a phone in the toilet; even if repaired, it won't last long. It's recommended that EV owners add flood coverage to their insurance. During rescue, ensure the tow truck has insulated equipment, as regular tow trucks may conduct electricity and cause fires. Also, avoid charging immediately after rain, as water in the charging port can cause a short circuit.

As a seasoned driver, I must warn you: driving an electric vehicle through water is more dangerous than a gasoline car! The drive battery is usually installed under the chassis, and a water depth of 20 cm can submerge it. Even if you spend 100,000 yuan to replace the entire battery pack, wiring harness corrosion will still trigger fault codes six months later. I've handled such repairs before, where the air conditioning compressor and brake booster pump failed one after another three months later. If you must drive through water, ensure the depth does not exceed the midpoint of the wheel hub, and a full vehicle insulation test is mandatory afterward.
