Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing.

[0026] In this embodiment, a method for online real-time assessment of the health state of an electric drive system of an electric vehicle includes the following steps:

[0027] Real-time collection of various working condition data of the electric drive system 2;

[0028] Statistically collect the data of each working condition in the form of a statistical chart to obtain a statistical table of working conditions;

[0029] Using the health status assessment model of each key component of the electric drive system, the corresponding load spectrum data is extracted from the working condition statistics table as the input parameters of the health status assessment model of each key component of the electric drive system, and the health status of each key component of the electric drive system 2 is evaluated. health status;

[0030] The health status of the electric drive sy...

Abstract

The invention discloses an online real-time evaluation method for the health state of an electric driving system of an electric vehicle. The method comprises the following steps of acquiring working condition data of the electric driving system in real time, performing statistics on the collected working condition data in a statistical chart mode to obtain a working condition statistical table, extracting corresponding load spectrum data from the working condition statistical table as input parameters of the health state evaluation model of each key component of the electric driving system by using the health state evaluation model of each key component of the electric driving system, and evaluating the health state of each key component of the electric driving system, and comprehensively obtaining the health state of the electric driving system according to the health states of the key components. The health state of the electric driving system can be evaluated in real time according to the actual working condition data of the electric driving system.

Description

technical field [0001] The invention belongs to the technical field of electric drive systems of electric vehicles, and in particular relates to a method for online real-time evaluation of the health status of electric drive systems of electric vehicles. Background technique [0002] Electric vehicles have become the first choice for most operating vehicles due to their low energy consumption. This undoubtedly poses a higher challenge to the health of the electric drive system, and it also makes users question the health of the electric drive system. In addition, the intelligentization of electric vehicles has become a development trend, which also requires the support of relevant technologies for predicting the health status of electric drive systems. Electric vehicle batteries have a state-of-health (SOH) function, but for electric drive systems, there is no such function. Based on the above, consumers will pay more and more attention to the health status of electric driv...
