Embodiment Construction

[0017] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various aspects of the present invention Modifications in equivalent forms all fall within the scope defined by the appended claims of this application.

[0018] Lithium batteries for electric vehicles have certain explosive characteristics. Therefore, when considering the storage capacity, we should not only consider the needs of battery replacement during the operation of electric vehicles, but also need to consider the charging mode (that is, charging after replacement, centralized charging, and batch charging) , grid load, operating costs, and the dangerous characteristics of lithium batteries for electric vehicles. Su...

Abstract

The invention provides a battery storage and concentrated charging optimization method for an electric bus charging and converting station. The method involves making an optimization principle on the basis of formulation of an optimization target; constructing an electric bus charging and converting station parameter design model; based on a power converting station, serving a single route, and under the condition that power conversion and charging are carried out when a vehicle only runs a round, giving calculation methods of a vehicle quantity, a standby battery quantity, a power conversion station quantity and charging power in different conditions; and finally giving an electric bus charging and converting station operation mode. By using the method provided by the invention, the problems existing in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of electric bus charging and swapping station batteries, and in particular relates to a battery storage and centralized charging optimization method for electric bus charging and swapping stations. Background technique [0002] Electric vehicles have outstanding advantages such as low noise, almost zero emission, and comprehensive utilization of energy. They are an important way to solve energy, environmental protection and other issues today. The performance of the electric vehicle power battery determines the performance of the electric vehicle to a large extent, and the technology related to the power battery is an important topic in the research of electric vehicles. [0003] Through research and analysis, the electric bus charging and swapping station has the following problems in terms of battery storage and centralized charging: [0004] (1) The design redundancy is too large. There is too much desi...
