Abstract :
The majority of state-of-charge based battery “fuel gauging” analog front end solutions are performed by either an analog-to-digital converter or a continuously integrated voltage-to-frequency converter. Comparable cost solutions are compared from the point of view of performance and difficulty of implementation. Laboratory results from both architectures are shown for common battery charge/discharge profiles
