Problems solved by technology

In addition, the power supply system of a single range extender and a single power battery is difficult to meet the charging needs of multiple loads
As another example, the multi-branch power distribution system with the publication number CN108819747A only involves multi-branch batteries and does not include electric energy generation modules

Embodiment Construction

[0084] In order to better understand the technical solutions of the present invention, the present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0085] Please refer to figure 1 , figure 1 It is a schematic diagram of an embodiment of the charging system provided by the present invention.

[0086] The power distribution system of the present invention is realized based on the CS structure of the charging system.

[0087] The entire charging system CS (Charging System) contains N (N ≥ 2) parallel energy sources S i , charging control unit CHRG (Charging Control Unit), hybrid control unit HCU (Hybrid Control Unit), busbar, charging gun. The charging gun passes through the busbar and the energy source S i connection, HCU communicates with each energy source S through the communication bus i connect. The charging control unit CHRG directly participates in the charging control communication of the charged vehicl...

Abstract

The invention provides a power distribution method and a power distribution system. The method is based on distribution and use of output power of each energy source Si when more than two energy sources Si are connected in parallel, and each energy source Si comprises an electric energy generation module Ti and an energy storage module Bi. The method comprises the following steps: acquiring a loadpower demand P<load>; obtaining state information of each energy source Si in N energy sources Si, wherein the state information comprises operation state information of the electric energy generation module Ti in the energy sources Si and electric quantity state information of the energy storage module Bi; and determining the output power P<Si> of each energy source Si in the N energy sources Sibased on the load power demand P<load> and the state information of the energy sources Si, wherein N is the number of the energy sources Si, N is larger than or equal to 2, i represents the ith energy source Si in the N energy sources Si, and i = 1, 2,..., N. According to the invention, frequent start and stop of the electric energy generation modules can be reduced to prolong the service life ofthe electric energy generation modules and reduce the energy loss of frequent start and stop of the electric energy generation modules.

Description

technical field [0001] The invention relates to the field of energy, in particular to a power distribution method and a distribution system. Background technique [0002] With the increase of electric vehicle charging demand, in order to meet the charging demand of multiple loads, multiple electric energy generation modules (such as micro gas turbine generator sets) and supporting energy storage modules are installed on one mobile device or in the charging station / parking lot (such as a power battery) will be a good choice as an energy source. [0003] When multiple energy sources are used, it is necessary to allocate power to each energy source. However, the existing power allocation methods only involve power systems that include multiple energy storage modules, or power systems that include a set of power generation modules and a set of energy storage modules. For example, the power supply system with publication number CN108973831A only includes a single range extender ...
