What is the wading depth of new energy vehicles?
1 Answers
10CM. Currently, the only clearly defined standard for the wading depth of new energy vehicles is the national standard GB/T18383.3. This standard specifies that the wading depth for new energy vehicles should be 10CM, with a speed of 20KM/h, a travel distance of 500m, and a wading time of 1.5min. Below are the relevant details: Wading test standards: In fact, local regions also have their own wading test standards for new energy vehicles. For example, Shanghai's pure electric vehicle admission policy includes the mandatory DB31T634-2012 standard, which requires simulating the wading conditions during vehicle operation. Pure electric vehicles must drive through 15 centimeters of water at a speed of over 30km/h for a total wading time of 10 minutes. Then, in 30 centimeters of water, they must drive forward and backward at a speed of no less than 5km/h for a total wading time of 10 minutes. This test further ensures that new energy vehicles have sufficient safety for driving. Additionally, Beijing has its own local standard for electric vehicles, defining a wading depth of 20CM. Test methods: Furthermore, according to the "Safety Requirements and Test Methods for Power Batteries in Electric Vehicles" issued by the General Administration of Quality Supervision, Inspection and Quarantine, clear safety indicators and test methods are provided for individual power batteries and modules of new energy vehicles. Among these test methods, it is required that saltwater can easily corrode products. Battery cells, in a fully charged state, should be soaked in a 3.5% NaCL (sodium chloride, simulating seawater) solution for 2 hours without any incidents such as fire or explosion.
