Inaccuracies of Estimating Remaining Cell Capacity with Voltage
Measurements Alone
Abstract: Implementing a battery fuel gauge can be done in a variety of ways including using voltage
measurements or coulomb counting. Although the use of voltage measurement has been a popular method of
choice, it does not produce the most accurate results available. This application note studies the voltage-based
method of fuel gauging for both Li-Ion and NiMH battery cells. Data is provided that demonstrates the high
degree of error introduced when implementing voltage m……
