Capacity configuration method of electric vehicle battery swap station power battery

Abstract

The invention discloses a capacity optimization configuration method for a power battery of an electric vehicle battery swap station. On the basis of defining the physical structure of the battery swap station, the state transition characteristics of the power battery are modeled through the actual operation mechanism of the battery swap station. The power batteries in the battery swap station have four states, and the four states are mutually converted as time goes on. Under a time-of-use electricity price mechanism, with the purpose of minimizing the annual total comprehensive cost of the electric vehicle battery swap station as a target, various equality and inequality constraints existing in actual operation conditions are comprehensively considered, and a mathematical optimization model of power battery capacity optimization configuration is obtained. By optimizing and solving the mathematical model, the operation scheduling strategy and the configuration number of the power batteries of the battery swap station can be obtained. According to the capacity configuration method, the comprehensive cost of the battery swap station is reduced, the operation profit of the battery swap station is improved, a theoretical basis can be provided for development planning and optimized operation of the electric vehicle battery swap station, and meanwhile, powerful support is provided for development of electric vehicles. The invention is suitable for the electric vehicle battery replacing station in the charging and battery replacing integrated mode.

Description

technical field [0001] The invention relates to the technical field of operation configuration of an electric vehicle swapping station, in particular to a capacity optimization configuration method for a power battery of an electric vehicle swapping station. Background technique [0002] When major problems such as energy crisis and environmental pollution emerged, people began to gradually explore the use of new energy, which led to the rapid development of wind power and photovoltaic power generation in the past ten years. However, their intermittent randomness has brought great challenges to the power grid. , so many scholars began to pursue the uncertainty of how to restrain its output. Battery energy storage has become the main method due to its advantages of fast response, safety and reliability. At the same time, in the automobile industry, electric vehicles have become a hot spot that people gradually tend to and pay attention to. With the introduction of a series o...

Problems solved by technology

If there are a large number of power batteries configured in the battery swap station, it is advantageous to meet the user's battery swap needs in actual operation, but this will inevitably increase the initial purchase cost; on the contrary, if the initial investment cost is reduced Equipped with a power battery, in the face of the actual situation of battery replacement, no more income from battery replacement can be obtained
