Abstract: Systems and methods are provided for electrolyte health management in a redox flow battery system. In one example, the redox flow battery system includes an injector arranged inside of an electrolyte tank. The injector may be configured to entrain a gas into electrolyte flowing from an inlet of the injector to an outlet of the injector.

Abstract: Systems and methods are provided for a redox flow batter system comprising a cylindrical electrolyte chamber fluidly coupled to a redox flow battery cell and at least one radial mixing manifold fluidly coupled to the cylindrical electrolyte chamber. The radial mixing manifold includes a flange configured to receive electrolyte from the redox flow battery cell and a manifold configured to mix and distribute the electrolyte within the cylindrical electrolyte chamber. The manifold includes a plurality of openings, at least one of which is a bottom opening, and extends from a first inner edge of the cylindrical electrolyte chamber to a second inner edge, lower than the first inner edge, of the cylindrical electrolyte chamber.

Abstract: Systems and methods are provided for a non-contact level sensor system for a liquid tank. The non-contact level sensor system includes a non-contact level sensor positioned above a maximum level of liquid in the liquid tank, a float configured to float on a surface of the liquid and reflect and/or scatter energy emitted by the non-contact level sensor. The position of the float in a plane perpendicular to the energy emitted by the non-contact level sensor is confined within a housing, and the vertical distance between the float and the non-contact level sensor is related to an amount of liquid inside the liquid tank.
