Abstract
Methods and systems are provided for a redox flow battery system. In one example, a method of operating a redox flow battery system includes, responsive to switching the redox flow battery system to an idle mode, initiating a first timer monitoring a first threshold period of time. An electrolyte pump may be activated when the first threshold period of time elapses, the electrolyte pump driving circulation of electrolytes through one or more electrode compartments.
Claims20
A method of operating a redox flow battery system, the method comprising:
- responsive to switching the redox flow battery system to an idle mode, wherein the idle mode includes operation of the redox flow battery system outside of a charging mode and outside of a discharging mode,
- initiating an off cycle timer monitoring an off cycle threshold period of time;
- activating an electrolyte pump in response to elapsing of the off cycle threshold period of time to circulate electrolytes through one or more electrode compartments.
A method for a redox flow battery system, comprising:
- responsive to operation of the redox flow battery system in an idle mode,
- cycling an electrolyte pump between an off interval and an on interval, the off interval having a duration corresponding to an off threshold period of time and the on interval having a duration corresponding to an on threshold period of time, wherein electrolytes are circulated through one or more electrode compartments during the on interval.
