What is the wading standard for pure electric vehicles?
1 Answers
Currently, there is no specific and clear standard for the wading depth of electric vehicles. However, according to the provisions of GB30381-2020 "Safety Requirements for Power Batteries of Electric Vehicles" regarding the waterproof performance test of power batteries, new energy vehicles can be almost completely submerged in water, and the battery will not have any problems within 30 minutes. Here is some additional information: Maximum wading depth: Since new energy vehicles do not have an exhaust system, it can be considered that submerging up to the chassis is the maximum wading depth. Therefore, new energy vehicles can be driven in heavy rain, and their wading capability is stronger than that of fuel-powered vehicles. The water level reaching the chassis is the limit. When the water level rises above the chassis to the lower gaps of the doors, water will enter the vehicle. Maintenance costs: According to current standards, new energy vehicles can only ensure safety during brief wading. Prolonged submersion in water carries the risk of spontaneous combustion. For new energy vehicles, replacing the battery once costs at least 50,000 to 60,000 yuan. If the cleaning and repair costs of other components are included, the overall maintenance cost of the vehicle will be very high.
