Whole vehicle high and low temperature test method for new energy vehicle

Abstract

The invention discloses a whole vehicle high and low temperature test method for a new energy vehicle, which comprises five steps of to-be-detected vehicle positioning, static cold and hot test, static test data acquisition and dynamic cold and hot test and dynamic test data acquisition. The operability is strong, the data detection precision is high, the operation state and the self structure state of the vehicle in an extreme temperature environment change condition can be thoroughly and effectively detected, and thus, on one hand, the accurate vehicle operation quality and the use limit life parameters can be obtained effectively, on the other hand, an accurate and reliable design basis is provided for a vehicle design scheme, an assembly process and part selection, and the vehicle quality, the operation stability and the reliability are improved.

Description

technical field [0001] The invention relates to a high and low temperature test method for a new energy vehicle, belonging to the technical field of electric vehicles. Background technique [0002] At present, with the increase in the use of various types of electric vehicles, strict requirements have been placed on the safety and reliability of electric vehicles. However, in actual use, due to factors such as the structural characteristics of electric vehicles, the Among them, changes in environmental factors such as high temperature and low temperature have a very serious impact on the operation status of electric vehicles, and even cause accidents such as power supply spontaneous combustion of some electric vehicles due to high temperature during operation. In the entire production process of quality inspection, there is a lack of effective test and simulation methods, which leads to the lack of effective guidance parameters for the design and production of electric vehic...

[0002] At present, with the increase in the use of various types of electric vehicles, strict requirements have been placed on the safety and reliability of electric vehicles. However, in actual use, due to factors such as the structural characteristics of electric vehicles, the Among them, changes in environmental factors such as high temperature and low temperature have a very serious impact on the operation status of electric vehicles, and even cause accidents such as power supply spontaneous combustion of some electric vehicles due to high temperature during operation. In the entire production process of quality inspection, there is a lack of effective test and simulation methods, which leads to the lack of effective guidance parameters for the design and production of electric vehicles, which in turn leads to large defects in vehicle design and production. Therefore, in response to this problem, There is an urgent need to develop a professional electric vehicle detection method to meet the needs of actual use
