Flow Battery Stack Cleaning via Pressure-Adjusted Electrolyte Scouring

The system performs preliminary detection of foreign matter in the stack unit before blockages occur. The detection apparatus monitors the stack unit continuously or at scheduled intervals, and when foreign matter is detected, the system automatically increases circulation loop pressure to flush out the foreign matter, preventing blockages before they affect battery operation

The system implements a feedback mechanism where the detection apparatus continuously monitors the stack unit for foreign matter. When foreign matter is detected, the control system automatically adjusts the pressure of the circulation loop to increase scouring strength and remove the foreign matter. This closed-loop feedback ensures the battery can operate continuously without manual intervention while maintaining reliability

Instead of maintaining high pressure continuously, the system uses periodic action by only increasing circulation loop pressure when foreign matter is detected by the detection apparatus. The pressure remains at normal operating levels during clean operation, and temporarily increases only when needed for foreign matter removal, thereby reducing overall energy consumption while maintaining effective cleaning capability

The system dynamically changes the pressure parameter of the circulation loop based on detection results. When foreign matter is detected, the pressure parameter is increased to enhance scouring strength for effective foreign matter removal. When no foreign matter is present, the pressure parameter is maintained at normal levels to minimize energy consumption
