Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0024] image 3 Shown is a schematic diagram of a hybrid control method provided by an embodiment of the present invention. like image 3 As shown, the hybrid power control method is applied to a hybrid power system, and the hybrid power system includes: a fuel cell, a storage battery and a motor. At the same time, the battery also obtains electric energy from the bus for charging.

[0025] The hybrid power control method monitors the voltage of th...

Abstract

The embodiment of the invention provides a hybrid power control method. The method comprises the steps that when the voltage value of a busbar is lower than V1_H, the voltage value of the busbar is made to approximate to V1_L by adjusting the electric energy supplied by a fuel battery to the busbar; otherwise, electric energy produced by the fuel battery is stopped being supplied to the busbar; when the voltage value of the busbar is higher than V2_L, the voltage value of the busbar is made to approximate to V2_H by adjusting the charging electric energy supplied by the busbar to a storage battery; otherwise, the storage battery is stopped being charged; when the voltage value of the busbar is lower than V3_H, the voltage value of the busbar is made to approximate to V3_L by adjusting the discharging electric energy supplied by the storage battery to the busbar; otherwise, the storage battery is stopped being charged; V3_L is smaller than V3_H smaller than V1_L smaller than V1_H smaller than V2_L smaller than V2_H. By means of the hybrid power control method, the problem that the failure risk is caused when hybrid power energy control depends on a communication bus in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a hybrid power control method and a hybrid power system. Background technique [0002] A fuel cell is an electrochemical device that directly converts the chemical energy of reactants into electrical energy. like figure 1 The shown proton exchange membrane fuel cell (PEMFC) consists of an electrolyte and a porous, water-permeable cathode and anode connected to both sides of the electrolysis. The cathode and anode of the battery are composed of a collector plate, a reaction gas flow channel, a gas diffusion layer (GDL), a microporous layer, and a catalytic layer. Among these components, the current collector plate is a component that collects electrons and outputs electric energy to the outside. Its material is generally composed of metals with high conductivity and stable mechanical properties. The reactant gas flow channel provides a passage for the reactant gas to flo...
