What is the wading depth standard for electric vehicles?
2 Answers
Electric vehicles have a wading depth standard that should not exceed 30 centimeters. Below are specific details about vehicle wading standards: 1. Vehicle Type: Different vehicle types have varying wading depth standards. Sedans have a wading depth of 20-30 centimeters, SUVs 30-60 centimeters, and hardcore off-road vehicles can reach 70-100 centimeters. 2. Issues After Wading: Deformation and damage to the crankshaft connecting rod mechanism. When a mixture of water and air enters the engine through the intake, since gases are compressible but liquids are not, the connecting rod may deform under the influence of water. If the driver attempts to start the vehicle at this point, the immense reactive force can cause the bent connecting rod to rub against the cylinder block, resulting in irreversible damage to the cylinder block.
The worst thing about driving an electric car is encountering floods or deep puddles. I learned this the hard way last summer. The rain was extremely heavy, and the road was flooded almost up to the wheel hubs. On impulse, I tried to drive through, only to hear a creaking sound from the chassis, and the battery warning light started flashing. When I took it in for repairs, the mechanic explained that electric car chassis have sealing adhesive and are waterproof up to IP67 standards, meaning they can handle water up to half a meter deep without issues. However, my car’s actual wading depth was only about 300 mm—beyond that, it becomes risky. He advised making it a habit to avoid deep water zones. If you live in a rainy area, get a waterproof guide or check the manual—for example, water levels shouldn’t exceed half the height of the wheels for safety. If you absolutely must drive through water, slow down, maintain stability, and afterward, dry off the connectors and inspect them. This affects both safety and the vehicle’s lifespan—don’t skimp on small things only to pay big later.
