The basic function of fuel gauge is to monitor the voltage, charge/discharge current and battery temperature, and to estimate the battery''s SOC and Full Charge Capacity (FCC) of battery. There are two classic methods to do
Battery fuel gauges determine the amount of charge remaining in a secondary battery, and how much longer (under specific operating conditions) the battery can continue providing power. Such indication
Most TI fuel gauges can also compute the battery SOH and the time to full or empty. This document describes tests that can be used to evaluate gauging accuracy in different situations. It does not include tests related to electrical specifications. Function testing checks the behavior of the gauge.
This test procedure can also be used as a reference for other fuel gauges. Charge the battery to full and connect a high accuracy current and voltage meter (or use the gauge data, if it is trusted). Log the data (time, voltage, current, temperature, reported SOC, and reported RM) every 1 to 10 seconds.
A system-side gauge uses the current and impedance to compensate the voltage drop which can result a more accurate SOC when the battery is first inserted. A fuel gauge with good accuracy can allow the system to obtain more energy from the battery without the worry of unexpected shutdown.
Well-tuned fuel gauges have demonstrated the ability to provide excellent fuel-gauging accuracy. We chose a test pattern that pushes the fuel gauge to extremes, where the battery is continually used without reaching full or empty for more than a week. Monitoring such a pattern is very challenging, even in the case of non-LFP cells.
Because the usable capacity will be different as the battery load changes, it is important for the gauge to choose which load it will use to predict the remaining capacity. Depending on the system load profile, the TI gauge can use the constant-current or constant-power model in the Impedance TrackTM algorithm.

A battery fuel gauge (BFG) helps to extend battery life by tracking the state of charge (SOC) and many other diagnostic features. In this paper, we present an approach to validate the SOC and time-to-shutdown (TTS) estimates of a BFG. Hardware-in-the-loop (HIL) testing under realistic usage scenarios provides a means for BFG ...
