Electric vehicles are afraid of flooding because they consist of three major components: motor, controller, and battery. Even with waterproof designs, they cannot withstand prolonged submersion. Reasons why they are not afraid of flooding: Electric vehicles have three types of waterproof designs: fully enclosed motor design, IP67 waterproof design, and individual battery protection design. Fully enclosed motor design: Electric vehicles rely solely on electricity for propulsion, unlike conventional internal combustion engine vehicles that require large amounts of air for operation. Electric vehicles do not need air assistance, so their motors are completely enclosed, preventing water ingress. IP67 waterproof design: Most components in electric vehicles use IP67 waterproof design, which allows them to be submerged in 1 meter of water for up to one hour. Individual battery protection design: Electric vehicle batteries have three layers of safety protection. The first is waterproof capability, the second is insulation protection for high-voltage components, and the third is structural protection for the entire battery pack, including resistance to external damage such as water immersion or collisions. Protection level: Since there is no internal combustion engine, there is no need to worry about air intake and exhaust issues, so their water-wading capability is far superior to that of conventional vehicles. Generally, they can operate normally in water up to 40 centimeters deep. The engine compartment of an electric vehicle is neatly arranged, with core components such as electronic controls and motors having adequate protection measures. The motor is fully enclosed and does not need to connect with the outside. Moreover, for safety reasons, the power train and cable input connectors of electric vehicles usually meet IPX4 or 5 protection levels.

As someone who has worked in the automotive industry for many years, I don't think pure electric vehicles are completely afraid of water immersion, but extra caution is still needed in flood scenarios. Their battery packs are usually designed with waterproof ratings, and common standards like IP67 can handle temporary underwater immersion without issues. However, I experienced an example last year during the rainy season: a neighbor's electric car parked by the roadside got flooded, resulting in a short circuit in the high-voltage circuit, which cost a fortune to repair. This reminds us that driving in daily rain or waterlogged areas is fine due to the vehicle's good sealing, but prolonged submersion can allow water to penetrate the battery or controller, leading to system failure. Pure electric vehicles have many electronic components, so it's important to regularly check seals in humid environments and avoid parking in low-lying areas. I recommend doing a simple visual inspection after heavy rain and immediately sending the vehicle for professional repair if any abnormalities are found—don't push your luck, safety comes first.

As an ordinary EV owner with two years of experience, I can say these vehicles handle light rain or road splashes well. They're designed with waterproofing in mind - just wipe with wipers and it's fine. But floods or waterlogging are real headaches. Once my garage had minor water accumulation (not deep, car still drivable), but post-incident inspection revealed slight rust on battery connectors. Thankfully timely intervention prevented major issues. If submerged deeper, water could enter battery casing causing short circuits - repair costs would be staggering. Daily driving is fine, but during heavy rains I avoid deep puddles and park on higher ground. Keeping the car dry prolongs lifespan. Don't assume EVs are invincible - regular maintenance is crucial.

From an environmental perspective, the waterproof design of pure electric vehicles is excellent, as it reduces the risk of water contact with electronic components and promotes sustainable mobility. However, flooding scenarios must be avoided—I have participated in community clean-up activities and witnessed submerged electric vehicles potentially leaking electricity or contaminating batteries, which can harm the ecosystem. Protection ratings like IP67 ensure stable operation in humid conditions, but complete submersion can cause internal short circuits. Damaged batteries are costly to recycle and environmentally unfriendly. It is advisable to choose models with good waterproofing and maintain them properly to protect the environment.

As someone who frequently repairs cars, I can confirm that pure electric vehicles are afraid of deep water submersion. I've handled cases where the battery pack was flooded after being submerged in floodwater, causing system alarms to fail and making repairs complex and expensive. Although there are sealing rings for protection, which can handle brief submersion, prolonged flooding can corrode wiring or damage the BMS module. I recommend regularly checking the chassis and battery cover seals and avoiding driving into flooded areas during heavy rain. If flooding occurs, immediately cut the power and have the vehicle towed for inspection to prevent short circuits and fires. Don't worry about minor daily issues—prevention is better than dealing with the damage.
