US 2015/0147983 A1 · METHOD AND APPARATUS FOR LOADING VOLTAGE THRESHOLDS FROM A BATTERY FOR A DEVICE

Abstract

A method and apparatus for determining whether to enable a functionality of a battery powered device upon connection to a battery is embodied by providing at least one voltage threshold in a memory of the battery that corresponds to a usable operating range limit of the battery and that is accessible by the battery powered device. Upon connection to the battery, the battery powered device acquires the voltage threshold or thresholds from the battery and programs itself with the threshold or thresholds. The battery powered device then compares a voltage of the battery to the threshold or threshold to determine whether the enable the functionality.

Dependent claims

A method for setting operating parameters in a battery powered device, comprising:

detecting connection to a battery prior to fully powering up the battery powered device,
determining, by the battery powered device, that the battery contains a memory having operating parameters stored therein, the operating parameters including at least one voltage threshold;
the battery powered device acquiring from the memory in the battery at least one voltage threshold;
and
the battery powered device programming itself with the at least one voltage threshold, and wherein the at least one voltage threshold is compared to a voltage of the battery by the battery powered device to determine whether to enable a functionality of the battery powered device should be enabled.
