Abstract ：Based on the smoothed particle hydrodynamics method, the wading simulation model of a battery electric vehicle was established by using AVL PreonLab. Combined with the wading test, the water flow and distribution inside and outside the car body were studied. This paper focused on the wading performance of the breathing hole of the reducer unitin the electric drive system and the inlet of the air conditioning system. By using simulation and tests, the design of the breathing hole was improved to prevent water from entering the lubricating oil. After the structural optimization, the flow path through which water entered the inlet of the air conditioning systemwas cut off. The results also show that the AVL PreonLab can effectively support the optimization design of vehicle water management.
