Embodiment 1

[0108] Such as figure 1 A full-matrix distribution method for high-power DC chargers is shown, including the establishment of a charger. The charger includes several charging guns, several power distribution units, and several power modules. The charging guns are sorted according to the order of charging Rules, the order sorts the charging guns from 1# charging gun to N# charging gun, and the value of N is from 1 to the total number of charging guns, and the value is a positive integer. All charging guns are not sorted by physical installation order, only by charging The sequence is the basis for sorting, each power module is connected to a power distribution unit, each power distribution unit is equipped with N output terminals, and the N output terminals of the power distribution unit are respectively connected to N charging guns, for each power module Preset an address;

[0109] Allocations are made according to the following three situations:

[0110] The first case: Dur...

Embodiment 2

[0227] The full-matrix distribution device for high-power DC chargers described in Embodiment 2 is matched with the full-matrix distribution method for high-power DC chargers described in Embodiment 1, including several power modules, digital A power distribution unit and several charging guns, each power module is connected to a power distribution unit, each power distribution unit is provided with N output terminals, and the N output terminals of the power distribution unit are respectively connected to N charging guns;

[0228] The charging gun is used to charge the electric vehicle, and the power module is used for AC / DC conversion;

[0229] The power distribution unit is provided with an input terminal and N digital terminals, and the input terminal of each power distribution unit is connected to a power module;

[0230] The N output ends of all power distribution units are respectively connected to the N charging guns.

[0231] Such as figure 1 As shown, one power modu...

Abstract

The invention discloses a full-matrix distribution method and device for a high-power direct-current charger, belongs to the technical field of new energy vehicles, and aims to solve the problem of low charging efficiency of the charger on the premise of meeting charging requirements of all charging vehicles by establishing the charger which comprises a plurality of charging guns, a plurality of power distribution units and a plurality of power modules. On the precondition that all charging vehicles can be charged, the requirements of a vehicle which is charged firstly are met preferentially;according to the charging demand of the vehicle and the priority of an overall operation strategy, power flexible distribution is carried out in real time, and charging power flexible distribution isachieved; on the premise that all the vehicles can be charged, the charging power requirement of the vehicles which are charged firstly is met preferentially; the charging pile is high in charging efficiency, the utilization rate of the power module is increased, the operation efficiency of the charging pile is improved, heat dissipation of the charging pile is reduced, the charging pile can workunder a better working condition, and the influence of a charger on the quality of a power grid can be reduced or improved.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and relates to a full-matrix distribution method and device for high-power DC chargers. Background technique [0002] The development trend of DC charging piles is high-power and high-current charging, and the application of DC charging piles is gradually becoming popular. The rectifier unit of the charging pile is composed of multiple AC / DC modules (usually 20kW / 30kW as a unit). During the application process, if the modules cannot be called and allocated reasonably, power will be wasted. Mainly faced with the following problems: [0003] 1. The module call is not flexible, and the allocated power does not match the needs of the vehicle, resulting in the phenomenon of large horse-drawn carts or small horse-drawn carts. The above two phenomena not only cause waste of resources, but also detrimental to the healthy operation of the module; [0004] 2. If the power distribution exceed...
