Abstract
Trigger pull tracking, charge time estimation, and other features for a power tool battery pack with wireless communication. A battery pack system includes a power tool battery pack and a processor. The battery pack includes a plurality of cells and a voltage sensor connected to the plurality of cells. The processor is in communication with the voltage sensor that detects a voltage across the plurality of cells using the voltage sensor. The processor further converts the voltage across the plurality of cells to a state of charge; determines a charge rate of a charger charging the battery pack; and determines a conversion factor based on the charge rate. The processor then generates a time to full charge of the battery pack based on the state of charge and the scalar conversion factor. The processor may further generate current traces for the battery pack.
