Electric vehicle wading condition simulation system

Abstract

An embodiment of the present invention provides a simulation system for electric vehicle wading conditions. The system includes: a simulation room and a main control computer arranged outside the simulation room, a water supply tower, a circulation pump A and a control valve A. The simulation room includes a pit, a pit inlet tank, and a pit outlet tank. The circulation pump A is set on the water supply pipeline between the water supply tower and the water inlet tank of the pit, and the electric vehicle to be tested is placed in the pit, and the main control computer controls the control valve A of the circulation pump A to open, and the circulation pump A turns the water supply tower The water in the pit is introduced into the pit through the water supply pipe and the pit inlet tank. In the embodiments of the present invention, by setting up facilities such as a main control computer, a simulation room, a water supply tower, a circulating pump, and a control valve, the wading test of an electric vehicle can be simulated more realistically. The detection system can conveniently control the wading depth, vehicle speed, and water flow velocity of the electric vehicle, thereby effectively realizing the wading simulation test of the electric vehicle under multiple working conditions.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a simulation system for wading working conditions of electric vehicles. Background technique [0002] Electric vehicles are an important trend in the development of the automotive industry. Electric vehicles are different from traditional vehicles in that they add high-voltage systems such as power batteries and motor controllers. Therefore, when an electric vehicle is driving on a flooded street or a low-lying puddle, the safety performance of the insulation short circuit is directly related to the driving safety of the electric vehicle and the safety of the occupants, and its safety may cause major safety accidents and personal injuries . Therefore, in the research and development process of electric vehicles, it is very necessary and important to test and detect the electric safety performance of electric vehicles under this working condition. [0003] At present, ...

AI Technical Summary

Problems solved by technology

[0004] The shortcoming of a kind of simulation experiment method of electric vehicle for wading working condition in the above-mentioned prior art is: 1) this kind of test investment is relatively large, especially site investment; 2) the safety of test personnel cannot be guaranteed

3) In winter, when the outdoor temperature is too low, the water is easy to freeze, so this kind of test cannot be carried out
