Abstract
In a preferred embodiment, voltage control system and method which include providing voltage sensing and control circuitry which measures the output voltage of a battery and provides an output signal to a flow control valve to cause the flow control valve to reduce the rate of flow of electrolyte when the output voltage of the battery is below a desired level and to cause the flow control valve to increase the rate of flow of electrolyte when the output voltage of the battery is above a desired level. The flow control valve may be a binary controlled solenoid valve responsive to a pulse-width-modulated signal from the sensing and control circuitry.
