A peak-staggered charging method for an intelligent charging pile and an intelligent charging pile system

Abstract

The invention discloses a peak shift charging method for an intelligent charging pile and an intelligent charging pile system. The charging method includes the following steps: S1, receiving charging demand information set by a user, and the charging demand information includes car use time, target electric power and start time; S2 , Obtain the current remaining power information of the vehicle, and calculate the charging time required to reach the target power according to the power of the charging pile; and obtain the segmented electricity price information of the location from the start time to the time span of the vehicle, and follow the segmented electricity price information from low to low Arrange to the highest level to obtain the corresponding time segment; S3. According to the order from the lower segment electricity price to the second-lowest segment electricity price, select the charging time segment plan until the sum of the time of the selected charging time segment plan is equal to the required charging time. ; S4, implement the charging operation according to the selected charging time period scheme. According to the set charging conditions, the present invention automatically plans a peak shift charging time period scheme, reduces the load on the power grid for peak power consumption, and reduces charging costs for users.

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
