Embodiment

[0048] Such as figure 1 As shown, a mobile welding robot based on fuel cell hybrid power includes a mobile welding robot body, a robot drive controller, and a power supply. The power supply supplies power to the robot drive controller with a 24V DC voltage. The welding robot body performs operation control, and the power supply mainly includes main power supply, auxiliary power supply and energy management unit. The main power supply is a proton exchange membrane fuel cell, and the auxiliary power supply is a lithium battery. The output end of the fuel cell is electrically connected to the DC bus through a unidirectional step-up DC / DC converter, and the output end of the lithium battery is electrically connected to the DC bus through a bidirectional step-up DC / DC converter. Connected to the DC bus, the energy management unit is respectively connected to the mobile welding robot, fuel cell, lithium battery and single / bidirectional DC / DC converter. The energy management unit de...

Abstract

The invention relates to an energy management method for a fuel cell hybrid mobile welding robot, which is mainly used to manage the charging of the fuel cell system unit to the lithium battery unit and the power supply of the robot by the hybrid power system as a whole, and constructs a fuel cell system unit and a lithium battery unit. Electrically connected energy management unit. According to the real-time load power demand of the robot and combined with the real-time state of charge SOC of the lithium battery, the present invention divides the hybrid power system into 9 operating modes to ensure that the fuel cell works under constant power or load balance. Compared with the prior art , avoiding the change of the continuous disturbance of the output characteristics of the fuel cell, making up for the lack of dynamic performance of the fuel cell, and further improving the power supply reliability and service life of the mobile welding robot driven by the fuel cell / lithium battery hybrid.

Description

technical field [0001] The invention relates to the control technology of a hybrid power system, in particular to an energy management method for a fuel cell hybrid power mobile welding robot. Background technique [0002] Mobile welding robots are more and more widely used in the fields of modern shipbuilding, petroleum, machinery, chemical industry and aerospace, such as welding of large ship cabins, decks, hulls, welding of large spherical tanks and field docking of large oil pipelines Operations, underwater operations, etc., but mobile welding robots generally use batteries as their power or cable power supply to drive, and batteries have disadvantages such as low power density, long single charging time, short service life, and large volume and weight. Both length and environmental impact greatly limit the application of mobile welding robots in the above fields. [0003] In order to better solve the above problems in the power system of the mobile welding robot, and m...
