SYSTEMS AND METHODS FOR NEW BATTERY IDENTIFICATION AND DERIVED BATTERY CAPACITY

摘要

The present subject matter includes systems and methods for detecting a new hearing aid battery and estimating hearing aid battery life by analyzing changes in battery voltage signatures during the hearing aid device booting process. The analysis may include analyzing a boot signature voltage drop occurring upon initial application of a higher load. The analysis may include analyzing a boot signature voltage slope occurring during sustained application of a higher load. The analysis may also include analyzing a boot signature voltage droop occurring throughout application of a lower load and application of a higher load.

主权项

1. A method for identifying hearing aid battery state, the method comprising:
executing a boot sequence on a hearing aid; detecting a battery voltage signature during one or more portions of the boot sequence, each portion of the boot sequence having an associated battery load sequence; determining one or more voltage signature characteristics within the battery voltage signature; and identifying a hearing aid battery state for a hearing aid battery based on the one or more voltage signature characteristics.
