Embodiment Construction

[0033] The present invention will be further described below in conjunction with specific implementation examples with reference to the accompanying drawings.

[0034] Such as figure 1 and figure 2 As shown, the electric vehicle power battery energy supply cost analysis method of the present invention comprises the following steps:

[0035] Step 1, build a hierarchical structure model: take the cost of the power battery energy supply mode of electric vehicles as the target layer A, take the three evaluation indicators of economic cost B1, social cost B2 and environmental cost B3 as the criterion layer, and use the evaluation indicators in the criterion layer The sub-indicators are the sub-criteria layer, the sub-indicators of economic cost B1 are time cost C1, the cost of building charging and swapping stations C2, the cost of operation and maintenance C3, and the cost of battery depreciation C4, and the sub-indicators of social cost B2 are the construction of charging and s...

Abstract

The invention discloses an electromobile energy supply cost analysis method based on a hierarchy analysis method, which comprises the following steps of: 1) constructing a hierarchical structure model by taking electromobile energy supply cost as a target layer, an evaluation index as a criterion layer, sub indexes of the evaluation index in the criterion layer as a sub criterion layer and an optional battery energy supply mode as a scheme layer, 2) quantitatively evaluating importance of the sub indexes under the criterion layer for a general target of the target layer according to a 1-9 scaling method and constructing a comparison judgment matrix, 3) calculating a weight vector of the matrix, 4) carrying out consistence check on the judgment matrix, modifying importance weights of the criterion layer and the sub criterion layer for the general target if the consistence check does not meet requirements till the consistence check meets the requirements, 5) outputting a synthetic weight of schemes of the scheme layer, and 6) carrying out decision analysis. The analysis method has reference and application values for the decision analysis of constructing a charging station and an electrical changing station.

Description

technical field [0001] The invention relates to a method for analyzing the energy supply cost of an electric vehicle, in particular to an analysis method for the energy supply cost of an electric vehicle based on the analytic hierarchy process, and belongs to the field of energy supply for a power battery of an electric vehicle. Background technique [0002] The power battery is the main energy carrier and power source of electric vehicles, and is one of the important components of electric vehicles. The use of power batteries, power battery energy supply technology and electric vehicle charging and swapping station technology have become key technologies to promote the industrialization of electric vehicles. [0003] At home and abroad, there are currently three main energy supply modes for electric vehicles: [0004] 1. Normal charging mode. This mode directly uses ordinary electricity to charge, which is a relatively common charging method at present. The charging curr...
