Intelligent charging pile peak-hour-avoiding charging method and intelligent charging pile system

Abstract

The invention discloses an intelligent charging pile peak-hour-avoiding charging method and an intelligent charging pile system. The intelligent charging pile peak-hour-avoiding charging method comprises the following steps that S1, charging demand information set by a user is received, wherein the charging demand information comprises vehicle use time, target electric quantity and start time; S2,the current remaining electric quantity information of a vehicle is acquired, and the charging time required for charging is calculated to reach the target electric quantity according to the chargingpile power; and segmented electricity price information of the location of the time span from the starting time to the vehicle using time, and the segmented electricity price information is arrangedfrom low to high to obtain corresponding time segments; S3, a charging time period scheme is selected according to the sequence from the lower segment price to the next lower segment price until the total time of the selected charging time period scheme is equal to the required charging time period; and S4, charging operation is implemented according to the selected charging time period scheme. According to the set charging conditions, the intelligent charging pile peak-hour-avoiding charging method automatically plans a peak-hour-avoiding charging time period scheme, the power grid burden ofpeak power consumption is reduced, and the charging cost of the user is reduced.

Description

technical field [0001] The invention relates to the technical field of charging control of charging piles, in particular to a peak shift charging method for an intelligent charging pile and an intelligent charging pile system. Background technique [0002] Under the guidance of policy support and market drive, my country's new energy industry continues to grow rapidly, and the production and sales of new energy vehicles rank first in the world. The construction of charging facilities has made positive contributions to the development of new energy vehicles. Charging facilities can be divided into private on-board charging piles and public charging piles in terms of their use scenarios. In the whole year of 2018, public charging infrastructure grew steadily, and on-board charging facilities grew faster. As of December 2018 At the end of the month, according to statistics from the China Electric Vehicle Charging Infrastructure Promotion Alliance, the total number of public cha...

Problems solved by technology

[0003] Although the construction of household charging piles has made a positive contribution to the development of electric vehicles, it has also brought great challenges to the public distribution network, because the charging habit of most users is to park the car with the charging gun after get off work. The car is connected, and charging starts immediately, so that the peak power consumption of household piles overlaps with the peak power consumption of residents, which leads to the problem that the load on the public distribution network is aggravated

Moreover, for individuals, they did not take advantage of the time-of-use electricity price policy formulated by the state, and failed to reduce charging costs and save costs.

[0004] Some solutions for peak-shift charging have also been proposed in the prior art, such as the patent publication number CN108790893A, which provides a solution to determine whether the vehicle is at peak power consumption after the vehicle is connected to the charging pile, and if so, delay the time Charging during off-peak electricity price periods or using energy storage modules, there is no intelligent planning scheme for charging piles in off-peak charging plans in the prior art
