What is the maximum water depth that new energy vehicles should not drive through?

[DiHarrison]

New energy vehicles should not drive through water that exceeds the height of the chassis. Below are precautions for driving new energy vehicles through water: Reduce speed and maintain distance: Keep the speed below 10km/h, drive cautiously and steadily, slow down, and maintain a safe distance to ensure safe passage. When the water depth exceeds the height of the vehicle's chassis, the vehicle should detour or stop; forcing through is strictly prohibited. Post-water crossing inspection: After passing through the water, it is necessary to get out of the car to inspect, remove any accumulated water, and check the chassis, especially the braking system, power battery, motor, and wiring harness to ensure there is no damage or short circuit.

When it comes to driving a new energy vehicle through water, the water depth must never exceed the center point of the wheels, approximately half the wheel height, with 30 to 40 centimeters being the upper limit. I've been driving this electric car for several years, and my biggest concern is water accumulation because the battery pack is located under the chassis. If submerged, it could short-circuit or experience insulation failure. Once during a light rainstorm, I drove slowly through shallow road water without any issues, but I heard that my neighbor's car had water above the wheel hubs, causing battery failure due to water ingress. Experts recommend maintaining a slow and steady speed when wading through water, avoiding acceleration to prevent creating waves. More critically, if the water depth exceeds this limit, it can easily lead to leakage in the high-voltage system. In the worst case, if the vehicle's electrical components are damaged, repair costs could run into thousands or even tens of thousands. Therefore, during heavy rain and water accumulation, it's best to detour or wait for the water to recede—safety first.

New energy vehicles are more sensitive to water than traditional cars. The high-voltage battery components may short-circuit and fail upon contact with water. Avoid taking risks when water depth exceeds ankle height. For instance, with water accumulation over 15 cm, although the chassis protection is good, the insulation of high-voltage wiring harnesses can be easily damaged when submerged. I've tested driving through shallow water several times without issues, but I absolutely avoid deep water areas. Additionally, after wading through water, it's essential to check the charging port and motor module to avoid residual moisture. Remember, vehicles are not designed for diving, so drive slowly through water or avoid it when possible. Related risks also include water pressure issues, which may damage sealing rings and cause long-term hidden dangers. Overall, keeping water depth below the wheel hub height is a fundamental principle.

The water shouldn't be too deep! Generally speaking, if the water reaches the center of the wheels, don't drive through it. 10 to 20 centimeters is the safe limit. Here's a simple way to judge: step out and test the water depth with your foot—if it goes past your calves, don't attempt it. For new energy vehicles, since the battery is located in the chassis, water submersion might trigger fault codes or damage the motor. When driving through water, maintain a steady, slow speed and avoid sudden acceleration. After fording, immediately check the underside of the car for any residual water marks. As a preventive measure, applying anti-rust treatment to the chassis before the rainy season can help. In short, depths vary, so caution is key.

I personally experienced an incident with a new energy vehicle in water. Last year during heavy rain, the water was less than half a wheel deep, and I drove through it for convenience, only to have the system alarms fail, costing me a fortune in repairs. The 4S technician advised that water depth should ideally not exceed 15 cm, as the battery pack is highly likely to take in water, risking fire or electrical failure. The issue relates to aging seals—newer cars fare slightly better, but older ones require extra caution. They recommend observing the path of vehicles ahead or using a stick to measure water depth before crossing. After driving through water, park and check the dashboard for any warnings. The risks are serious; detouring around deep water is the wise choice.

The key to wading depth for new energy vehicles lies in battery and circuit protection. Don't drive if water exceeds half the wheel height (30cm)! Otherwise, water pressure may damage insulation causing short circuits or leakage. I regularly inspect and maintain - chassis sealing is crucial. Dry promptly or get professional cleaning after wading. Also watch for tire slippage - deep water can cause loss of control. Related point: Insurance may not cover water damage - safety trumps savings. Use low gear and slow speed when wading to avoid creating waves. In summary, keeping water depth around 10cm is safest. Prevention is key - don't take chances.
