How deep can water be before a new energy vehicle cannot drive?

New energy vehicles should not be driven in water deeper than 30cm. Compared to traditional fuel vehicles, new energy vehicles have certain advantages in water wading capability. Even if completely submerged, they will not cause electric leakage or personal injury, as long as the water depth is kept within 30 centimeters, which is about half the height of the tire, and the vehicle can pass through slowly. Additional information: Tips for driving through waterlogged areas in rainy weather are as follows: 1. When encountering waterlogged roads while driving: Slow down or stop to observe. If the water level reaches two-thirds of the bumper or tire height, driving through poses certain risks. High speed increases the actual water depth the vehicle passes through, potentially allowing water to enter the cabin from the engine compartment or chassis. Avoid driving against waves created by large vehicles. If the water level is high, try to detour and avoid forcing your way through. 2. While driving through water: Maintain a low speed, avoid stopping or shifting gears, do not release the throttle, and do not accelerate. Instead, drive steadily at a low gear with moderate throttle to pass through smoothly, avoiding splashing large waves or water. 3. If the vehicle stalls in water: Do not attempt to restart it immediately. Take measures to tow the vehicle to a safer area with less water as soon as possible. Serious engine water intake can occur, where water may enter the cylinders through the air filter and intake valves via the intake pipe. Do not try to restart the engine, as it may cause deformation of critical components like the crankshaft and connecting rods, leading to engine vibration or even component breakage. Stalling in water likely means the engine has taken in water, and the vehicle should only be towed in neutral to a repair shop for cleaning. 4. After driving through water: Remove moisture from the brake pads promptly. Drive at low speed while lightly pressing the throttle and gently applying the brakes. Those unfamiliar with simultaneous operation can press the brakes multiple times, ensuring slow speed and repeated actions to generate heat through friction between the brake drum and pads, evaporating the moisture.
I've been driving a new energy vehicle for over two years and encountered heavy rain several times. Never drive through water deeper than 15 cm, which is about the height of the wheel center. Electric cars have low chassis with batteries mounted underneath - water ingress can cause short circuits and total failure, with repairs costing tens of thousands. Floating risk is also serious; in deep water the car may float and lose steering control. Once I almost drifted off the road. Always check flood maps before driving in rain, detour around deep water, never force through. Regularly maintain underbody panels to prevent water intrusion. Develop good habits for safety and cost savings - battery repairs take long and disrupt daily commutes. True story: A friend's car was totaled after flooding, full of regrets.
New energy vehicle batteries and circuits are vulnerable to water. Avoid driving through water deeper than 10 to 15 cm. I've seen test videos where water entering an electric vehicle's chassis causes severe short circuits, damaging control modules that are costly and time-consuming to repair. In deep water, vehicles gain buoyancy, becoming unstable and prone to tipping. Before driving in rain, check weather forecasts and avoid flooded areas. If water covers the road, change routes or park immediately. Regular maintenance should ensure clear drainage holes and a dust-free chassis. Protecting your vehicle extends its lifespan and ensures safer driving. Remember, safety first—don't risk it to save a few minutes.
