    Figure 1: The principle of fuel gauging based on coulomb counting: The stored energy represents state of charge. A circuit measures the in- and out-flowing current.

    For simplicity, you can imagine the battery as an energy storage device analogous to a fuel tank. However, measuring stored energy from an electrochemical device is far more complex than that comparison
