Method and device of charging segmented billing for electric vehicle fast charging station

Abstract

The invention relates to a method and a device of charging segmented billing for an electric vehicle fast charging station. The method comprises the following steps: determining the parking fee of theelectric vehicle according to the parking time of the electric vehicle; determining the charging fee of the electric vehicle according to the charging power consumption of the electric vehicle; determining the charging service fee of the electric vehicle by using a time-sharing service fee objective function of the electric vehicle and constraint conditions thereof; determining the total chargingfee of the electric vehicle by using the parking fee, the charging fee and the charging service fee of the electric vehicle. According to the technical solution provided by method and device of charging segmented billing for the electric vehicle fast charging station, a time-sharing service fee price strategy is established, and a reference basis for the electric vehicle fast charging station operator to flexibly formulate the service fee and the parking fee price is provided. Through the difference of service fees in different time periods, the user can be guided to charge during the low charging period, which can alleviate the peak-to-valley difference of the power grid, reduce the occupancy of the charging pile in charging peak, and improve the utilization rate of the charging pile throughout the day.

Description

technical field [0001] The present invention relates to the field of charging stations for electric vehicles, in particular to a charging method and device for segmental charging at fast charging stations for electric vehicles. Background technique [0002] Peak-valley time-of-use electricity price is one of the measures to implement demand-side management. The electricity load curve has obvious peaks and valleys. The purpose of peak filling affects the shape of the load curve. [0003] The current time-of-use electricity price of the power grid is divided into three periods: peak, valley and flat according to the load demand period of traditional electricity users. The charging behavior of electric vehicles, as a special electricity user, is affected by the user's driving rules. When charging on a large scale connected to the grid, the peak and valley periods formed according to the traditional industrial electricity consumption habits will change, such as 17: During the...

AI Technical Summary

Problems solved by technology

The charging service fee accounts for a large proportion of the user's charging fee, so there are several problems: 1. It cannot guide users to charge at off-peak times

2. The space occupied by fuel vehicles and the problem that electric vehicles still occupy charging parking spaces after charging are prominent

[0009] 2. At present, many urban fast charging stations are built in parking lots. In addition to paying charging fees, users also need to pay parking fees
