Comprehensive benefit evaluation method for air supply mode of air conditioner of electric vehicle

Abstract

The invention discloses an electric vehicle air conditioner air supply mode comprehensive benefit evaluation method, which comprises the following steps: obtaining evaluation index parameters used for evaluating the electric vehicle air conditioner air supply mode comprehensive benefit, and constructing an initial matrix; determining a data type of the evaluation index; performing forward processing on the evaluation indexes, and constructing a forward initial matrix; standardization processing is carried out on the evaluation indexes after the forward processing, and a standard decision matrix is constructed; calculating the objective weight of each evaluation index by using an entropy weight method; and a TOPSIS model based on an entropy weight method is established, all the air supply modes are ranked, and therefore the optimal air supply mode is obtained. Theoretical reference and technical support are provided for design and optimization of the electric automobile air conditioning system, the comprehensive evaluation effect of all the air supply modes can be embodied, the advantages and disadvantages of all the air supply modes under a single evaluation index can be given, and the evaluation result is more rigorous and accurate.
