Fuel cell hybrid power mobile welding robot energy management method

The invention relates to a fuel cell hybrid power mobile welding robot energy management method, which is mainly used for managing a fuel cell system unit to charge a lithium battery unit and a hybridpower system to power a robot as a whole and constructing an energy management unit electrically connected with the fuel cell system unit and the lithium battery unit. According to the real-time robot load power demand, combined with the real-time state of charge (SOC) of a lithium battery, a hybrid power system is divided into nine operating modes to ensure that a fuel cell operates in a constant power or load balancing state. Compared with the prior art, the method of the invention avoids the change brought by continuous disturbance of the fuel cell output characteristics, makes up for thedeficiency of dynamic performance of the fuel cell, and further improves the power supply reliability and service life of the mobile welding robot under the drive of the fuel cell/lithium battery hybrid power. 本发明涉及种燃料电池混合动力移动
