Electric automobile wading working condition simulation system

Abstract

The invention provides an electric automobile wading working condition simulation system in one embodiment. The system comprises a simulation room, a main control computer, a water supply tower, a circulating pump A and a control valve A, wherein the main control computer, the water supply tower, the circulating pump A and the control valve A are arranged outside the simulation room; a pit, a pit water inlet groove and a pit water outlet groove are formed in the simulation room; the circulating pump A is arranged on a water supply pipeline between the water supply tower and the pit water inlet groove; an electric automobile to be tested is parked in the pit; the main control computer controls the opening of the control valve A of the circulating pump A and the control valve A is capable of guiding water in the water supply tower into the pit via the water supply pipeline and the pit water inlet groove. The electric automobile wading working condition simulation system is capable of really simulating the wading working condition test of the electric automobile by use of the facilities such as the main control computer, the simulation room, the simulation room, the water supply tower, the circulating pump and the control valve. The detection system is capable of conveniently controlling the wading depth of the electric automobile, the automobile speed and the water flow speed, and effectively realizing the wading simulation tests of multiple working conditions of the electric automobile.

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
