TECHNIQUES TO PROVIDE A LOW CAPACITY NOTIFICATION FOR AN ENERGY STORE DEVICE

摘要

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.

evaluating measurement criteria to determine whether to initiate a voltage measurement for the energy storage device, wherein the measurement criteria specifies a maximum number of voltage measurements within a time period; when the voltage measurement is within the maximum number of voltage measurements within the time period, measuring a voltage for the energy storage device; after measuring the voltage for the energy storage device, adjusting a counter for the node based on the measured voltage, wherein the counter is adjusted in one direction if the measured voltage is below a voltage limit and the counter is adjusted in an opposite direction if the measured voltage meets the voltage limit; and determining if the counter meets a low capacity threshold, wherein the low capacity threshold corresponds to a plurality of measurements below the voltage limit;
when the counter meets the low capacity threshold, determining that the low capacity condition for the energy storage device exists, andwhen the counter is below the low capacity threshold, storing a value of the counter for use with a next voltage measurement.
