Embodiment Construction

[0049] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.

[0050] The present invention aims at the highest service efficiency of the power station, and the service efficiency is defined as the lowest cost required for a single service: cost required for a single service = total cost / total number of times of service.

[0051] Assuming that the power station is operating at full load, the constraint on the total number of services is mainly the rated power of the power station p w and a single battery capacity C b .

[0052] In principle, the number of power exchange services provided per day is shown in formula (1)

[0053]

[0054] Assuming that the total service capacity is not restricted by t...

Abstract

The invention relates to a system and a method for optimizing the battery number and charging rate of a battery swapping station. The system comprises a battery swapping station and battery parameter input unit, a battery life attenuation model library, a charging rate calculation unit, and a battery number calculation unit. According to the electrical parameters and economic parameters of a battery swapping station and the batteries therein as well as battery life attenuation models, the charging rate is calculated based on minimum annual cost of the batteries in the battery swapping station, and further, the number of the batteries in the battery swapping station is calculated. Through the system and the method of the invention, the optimal charging rate and battery number of a battery swapping station can be calculated accurately, and the design of the scale of battery swapping stations can be guided effectively.

Description

technical field [0001] The invention belongs to the field of battery swapping stations for electric vehicles, and in particular relates to a system and method for optimizing the battery quantity and charging rate of a swapping station. Background technique [0002] The charging and swapping station is an energy station that provides charging and quick replacement of the power battery of an electric vehicle. Electric vehicles require their electrical energy to be supplemented for continuous driving. The supplement of electric energy can be divided into vehicle charging (fast charging, conventional charging and slow charging) and quick battery replacement. [0003] At present, the charging function in the charging and swapping station is under the current situation that the number of electric vehicles is rapidly increasing. Because the charging time is generally long, it cannot meet the fast charging needs of electric vehicle users. The battery swapping function is more and m...
