DESIGN FEATURES An Accurate Battery Gas Gauge
by James Herr Introduction
A battery fuel gauge can be implemented in a variety of ways. The
most popular is to derive the remaining battery capacity from the battery
voltage. This method has advantages
in that it is easy to implement and
relatively low in cost, but it does have
one major drawback: It is relatively
inaccurate. Battery voltage has, at
best, an inconsistent relationship
to battery capacityвЂ”the relationship
varies greatly depending on battery
discharge rate and temperature.
The latest portable devices, though,
require more accurate battery gas
gauging. For instance, a portable
computer or PDA may need to save
data, or state information, and shut
down when the battery reaches a
critical discharge point. Accurate
prediction of this point allows the
device to safely run longer on battery
power. For applications that require …
