With the battery fuel gauge on the system side, the gauge can control or manage other main battery management functions in single-cell applications, such as charge control and battery pack authentication. In many ways, the battery fuel gauge is in the best position to do this since it acquires the intricate details about the state of the battery.
Impedance Track Fuel Gauge – An impedance-based battery fuel gauge, as the name implies, uses the measured impedance of the battery’s cells as a key input to its remaining capacity predictions. The gauge measures and stores in real-time the battery pack’s resistance as a function of state-of-charge.
Besides accuracy and predictability, the other key benefit of an impedance-based battery fuel gauge is that it enables the fuel gauge to reside on the system’s main board (as opposed to the battery pack) in single-cell Li-Ion applications – even in systems with a removable battery pack.
