A computer-implemented method for determining a state of a redox flow battery comprises the measurement of pH and/or bulk magnetic susceptibility during operation of the redox flow battery to determine a current state of the battery. As such, the method may enable control of the battery to be optimised in real-time. For example, if the state of the battery is determined to be sub-optimal, action can be taken to improve the state of the battery. Therefore, the method can also include adjusting operation of the battery to control its determined state. This may therefore enable real-time optimisation of the battery, which can enhance both battery lifetime and operation, as well as ensuring that energy demands can be met. The state of the battery may be a number of different properties including state of charge, state of health, degree of exposure of the electrolyte to air (triggering an alert if too high), current, temperature, cycling history, and future capacity decline.
