Embodiment Construction

[0061] 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.

[0062] Please refer to figure 1 , figure 1 It is a schematic diagram of an embodiment of the charging system provided by the present invention.

[0063] The entire charging system CS (Charging System) includes N 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 vehicle. The software and hardware functional requirements of the charging control unit CHRG follow the national standard (GB T27930-2015)...

Abstract

The present invention provides a multi-mode charging method, which is used to use the energy source S i In the mode of charging an external load, the energy source S i Including power generation module T i and energy storage module B i , the method includes: obtaining an energy source S i The allocated output power P Si , based on the output power P Si The size of the energy source S is determined by i The initial working mode of the battery is one of low power L mode, medium power M mode, and high power H mode; during the charging process, with the output power P Si change, so that the energy source S i Automatic switching in L mode, M mode, H mode and T mode. The multi-mode charging method of the present invention enables the energy source to switch automatically in multiple working modes, so that the energy source can accurately track the constantly changing load power demand. The setting of switching conditions between working modes makes the output of the energy source more gentle, reduces the start-up and shutdown operations of the gas turbine, protects the gas turbine while reducing system loss and improving efficiency.

Description

technical field [0001] The invention relates to the field of energy, in particular to a multi-mode charging method. Background technique [0002] In the power supply for charging electric vehicles, for a single energy source (including electric energy generation module + energy storage module), since it contains two power sources, as the charging process progresses, the load power demand will gradually decrease, but Some situations will lead to an increase in load power demand (for example, for a power battery whose load is an electric vehicle, theoretically, the load power demand presents a stepwise decline, and each power step is horizontal, but the actual charging time of each power step There will be an increase in the second half; or an increase in power demand due to the access of a new load). [0003] In the existing charging technology, in the Chinese invention patent with the publication number CN109484242A, a mobile charging system and method based on the developm...
