Flow battery shunt current
WebThe simplest protection against reversed-battery current is a series (a) or shunt (b) diode. As an improved battery-reversal measure, you can add a pnp transistor as a high-side switch between the battery and the load (Figure 2a). When you install the battery correctly, the current-limiting resistor in the base lead forward-biases the base ... WebThe shunt current loss is one of main factors to affect the performance of the vanadium redox flow battery, which will shorten the cycle life and decrease the energy transfer efficiency.
