Are New Energy Vehicles Afraid of Water Immersion?

[DeLeo]

New energy vehicles are not afraid of water immersion. The battery modules of new energy vehicles are completely sealed, so even if submerged in water, there is no danger. Here is some extended information: 1. New energy vehicles: The most obvious difference between electric vehicles and fuel-powered vehicles is the energy supply mode. New energy vehicles use batteries to provide energy, do not require air participation, and do not have internal combustion engines, so there are no issues with air intake and exhaust. This makes them more capable of wading through water than fuel-powered vehicles. 2. Charging in rainy weather: Charging piles comply with national standards and undergo strict regulations and various tests before leaving the factory, so charging in rainy weather generally does not pose significant problems. The charging gun head and its ports are insulated from each other. Current only flows when the charging gun is fully inserted into the charging port. When the gun is removed, the detection part disconnects first, stopping the current flow, thus providing the highest level of safety.

As a long-term electric vehicle owner, I've found that new energy vehicles do have concerns regarding water immersion. Although waterproofing is considered in the design—for instance, battery packs often meet the IP67 standard, meaning short-term immersion in shallow water is generally not an issue—the risk escalates in cases of flooding that submerges the undercarriage or deep water accumulation from heavy rain. Water seeping into electrical circuits can cause battery short circuits, potentially leading to fires or explosions; I've personally witnessed such incidents. Therefore, during rainy seasons or flood warnings, I make a point to avoid driving through waterlogged areas and choose elevated spots for parking. If the vehicle accidentally gets submerged, the first step is to cut off the power and avoid starting it, then promptly call for professional towing to a service center for inspection—safety always comes first. Regular car washes or exposure to light rain are harmless, but it's crucial for owners to heed water-related warnings and develop the habit of periodically checking seals to minimize risks.

From a safety perspective, new energy vehicles pose greater potential hazards in flooding scenarios. Based on my experience with numerous vehicle accident data, once an electric vehicle's battery is submerged for an extended period, internal chemical reactions may become uncontrollable, leading to thermal runaway or even fires—far more severe than water entering a fuel-powered engine. While waterproof designs exist, the risk of seal failure increases with flood depth and water pressure. As an ordinary driver, I would check weather forecasts in advance to avoid flood-prone areas and refrain from driving through water deeper than 30 cm. If flooding occurs, do not attempt self-rescue; evacuate the vehicle immediately and contact emergency services. It's advisable to enhance vehicle maintenance during the rainy season, inspecting the underbody waterproofing layer for integrity and ensuring the high-voltage system remains isolated.

I've driven a new energy vehicle for several years and feel relatively confident during the rainy season. Normal rain or even car washes are no problem – the car is designed with waterproof measures. For example, my car could slowly drive through shallow waters without issues. However, if it gets submerged, say waist-deep in floodwater, that's a different story. The battery can short-circuit when exposed to large amounts of water, potentially leading to dangerous spontaneous combustion. So I've learned to avoid driving through low-lying areas, especially parking on higher ground during typhoons. If the car gets flooded, don't touch any buttons and call for repairs immediately. In short, just drive carefully in wet conditions and don't let the car sit in water for too long.
