What is the wading standard for pure electric vehicles?

[Perez]

Currently, there is no specific and clear standard for the wading depth of electric vehicles. However, according to the 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 for 30 minutes without any issues with the battery. Here is some additional information: 1. Maximum wading depth: Since new energy vehicles do not have an exhaust system, it can be considered that the maximum wading depth is when the water reaches the chassis. Therefore, new energy vehicles can drive in heavy rain, and their wading capability is stronger than that of fuel vehicles. The limit is when the water level reaches the chassis; if the water level rises above the chassis to the lower gaps of the doors, water will enter the cabin. 2. Repair costs: According to current standards, new energy vehicles can only ensure safety during brief wading. Prolonged submersion in water carries a risk of spontaneous combustion. For new energy vehicles, replacing the battery alone costs at least 50,000 to 60,000 yuan. If you add the cleaning and repair costs of other components, the overall repair cost of the vehicle will be very high.
