Will an electric car get damaged if it keeps getting rained on?

An electric car will get damaged if it keeps getting rained on. Specific definition of a water-damaged vehicle: The vehicle starts to accumulate water, and internal components are damaged due to water accumulation. There are corresponding flood damage levels for water-damaged vehicles. Such vehicles should be properly handled and should not be abandoned arbitrarily. Classification of flood damage levels for water-damaged vehicles: Flood level 1: Water just reaches the vehicle chassis. Flood level 2: Water reaches half of the wheels. Flood level 3: Water almost completely submerges the tires. Flood level 4: Water reaches the engine hood. Flood level 5: Water completely submerges the engine hood. Flood level 6: Water submerges the car roof.
I've been driving an electric car for over five years. I remember last year during the rainy season, I left the car parked outdoors for a whole month without moving it, and later found some rust spots underneath the body. The windshield wipers also occasionally malfunctioned. Although electric cars are designed with waterproofing in mind, such as sealed seams and anti-rust coatings, prolonged exposure to rain can allow water to seep into mechanical connection points, leading to corrosion of metal parts and electrical connectors. Especially around the battery pack, moisture accumulation can easily cause short circuits or performance degradation. Once, when starting the car, the dashboard showed an error, and upon inspection, it turned out the door lock sensor had water ingress. So, it's best not to leave an electric car exposed to rain every day. Finding a carport or using a car cover is advisable, and regularly washing the car body can also reduce the risk of rust.
I'm particularly fascinated by the intricate details of cars, and when it comes to electric vehicles (EVs) getting rained on, it really depends on the design. Modern EV battery packs are equipped with IP67 or IP68 protection ratings, meaning they can theoretically withstand short-term immersion without issues. However, prolonged exposure to rain may allow water to seep through door gaps or chassis vents, potentially accumulating in the electrical system and causing amplifier failures or short circuits. For instance, excessive moisture around the onboard charging port can oxidize the connectors, affecting charging efficiency. It's advisable to park in elevated or covered areas whenever possible. After each rainfall, check for accumulated water around the wheels and ensure drainage holes remain unobstructed. These small habits can significantly extend the lifespan of your EV.
From an environmental perspective, prolonged exposure of electric vehicles to rain is not ideal. The acidic substances in rainwater can corrode the car body and electronic components, accelerating part aging, shortening the vehicle's lifespan, and leading to resource wastage. Electric vehicles rely more on delicate circuits compared to traditional fuel-powered cars. Once water infiltrates, the degradation of batteries can result in greater pollution during recycling. I once saw a neighbor's electric vehicle parked outdoors for two years, with the hood covered in rust, costing a significant amount in repairs. Therefore, parking in garages or using rain covers more often protects electric vehicles and reduces environmental burdens.
