A method for processing sensor data in a distributed sensor system includes generating aggregated sensor data values associated with a first sensor and belonging to one or more aggregation time intervals, tagging each aggregated sensor data value with an aggregation indicator. The aggregation indicator has a first value indicating partial aggregation and has a second value indicating complete aggregation. In some embodiments, the method combines the partially aggregated sensor data belonging to the same time interval into a complete aggregated sensor data.

Method to combine partially aggregated sensor data in a distributed sensor system

A battery pack management system adjusts the relative state-of-charge of respective battery blocks in a battery pack to equalize (i.e., align, balance or otherwise make similar) the peak battery block voltages (i.e., maximum or 'upper peak' battery block voltages when the battery pack is being charged and/or minimum or 'lower peak' battery block voltages when the battery is being discharged). Upon detecting an anomalous battery block that exhibits outlier upper and lower peak voltages, the battery pack management system adjusts the relative state of charge of respective battery blocks to center their respective upper and lower peak voltages between operating limits, thus maximizing the operating margin of the battery pack as a whole.

A distributed sensor system includes a set of spatially distributed base units and a central server both in communication with a data network. Each base unit includes a controller and one or more sensor modules where each sensor module includes a sensor configured to measure an air quality parameter. Each base unit transmits raw sensor data associated with each of the sensor modules over the data network and the central server receives the raw sensor data from the base units and stores the raw sensor data in a database.

Margin-based battery charge balancing

Methods of calibrating sensors in a distributed sensor system including a set of spatially distributed base units in communication with a central server over a data network include using a reference sensor, using a reference base unit, using crowd-sourced calibration, using sensor data collected in the same base unit, using sensor cross-sensitivity, or using sensor data from known environmental conditions.
