Will Electric Vehicles Have Problems When Driving Through Deep Water?
2 Answers
Electric vehicles can encounter problems when driving through deep water, so it's best to avoid water whenever possible. Here are the correct methods for electric vehicles to navigate through water: 1. When there is standing water on the road: Ensure the road conditions are good, and if the water does not exceed half the height of the tires, slow down, observe the situation of the vehicle ahead, and pass through in sequence. 2. When encountering flooded sections: Regardless of the water depth, do not attempt to pass. The vehicle can easily be pushed off the road and swept into rapid currents, and the road surface beneath the water may already be completely damaged by the flow. 3. If you accidentally drive into deep water: If the vehicle begins to float, immediately open the doors to allow water to enter the cabin, which can reduce buoyancy and help the wheels regain traction on the ground. If you are certain that the water ahead is not too deep and the vehicle has not 'stalled,' continue moving forward to a safe area. If the vehicle has already stalled, this can also prevent a situation where the doors cannot be opened, making escape impossible. 4. After driving through water: Contact after-sales service and insurance immediately. Vehicles that have been through water may have many hidden dangers and should be thoroughly inspected before being driven again.
Speaking of driving an electric car through deep water, I do have a heart-stopping experience. That day it was pouring rain, and I thought it would be convenient to drive straight through a flooded ditch. The water level was almost reaching the bottom of the car. Although electric cars don’t stall like gasoline cars when water gets in, that big battery pack is a real concern. The battery casing is designed to be sealed, but under high water pressure, water can seep in and cause a short circuit, or even trigger an arc spark, potentially totaling the car. After that incident, I became more cautious—if the water level exceeds half the wheel height, it’s better not to take the risk and find a detour instead. Usually, I check the weather forecast more often and plan routes to avoid flooded areas. If I absolutely must cross, I drive slowly and avoid splashing water. Battery repairs are extremely expensive, costing at least tens of thousands, plus the wait for parts. Safe driving is the golden rule, and now I’ve developed the habit of anticipating road conditions in advance. I’ve discussed this in car enthusiast groups, and many have suffered losses—electric cars can’t afford to be careless in this regard either.
