of effective battery power is a significant aspect for military
use, but it is rarely available with primary batteries. The use of
State of Charge (SoC) Indicators and "Smart Bus" type
communications enable users to monitor the health and charge state
of the battery. While such implementations add to the cost of each
battery, they reduce the total life cycle cost of the entire
battery inventory, by reducing unnecessary replacement of
batteries and enable the use of much of the available power.
For rechargeable batteries, a combat device also
requires an additional State of Health (SoH) indication that
depicts the expected life expectancy of the fully charged device.
In a network centric environment, where
communications (and transmission) of data at high capacity are
required, power requirements for portable and mobile electronics
is outgrowing existing power sources capacity, leading to a
shorter service per battery. The use of regenerable power is
therefore becoming critical for military missions.
