Abstract

Disclosed are various systems and methods related to forecasting a low capacity state in an energy storage device of a node. A voltage is measured for the energy storage device of the node based upon measurement criteria. A counter for the node is adjusted based on the measured voltage, where the counter represents a history of instances of previous measurements of the voltage with respect to a voltage limit. The counter is adjusted in one direction if the measured voltage is below the voltage limit, and the counter is adjusted in the opposite direction if the measured voltage meets the voltage limit. If the counter meets a low capacity threshold, a low capacity condition is activated for the node. If the counter fails to meet the low capacity threshold, the value of the counter is stored for subsequent use during the next evaluation of the energy storage device.
