  • METHOD AND APPARATUS FOR TEMPERATURE COMPENSATION OF LOW BATTERY VOLTAGE THRESHOLDS AND VOLTAGE DROOP DETECTION IN A MEDICAL DEVICE
    Publication number: 20230190148
    Abstract: A method for operating a medical device includes activating a processor that receives electrical power from a battery in the medical device, measuring a temperature within a housing of the medical device, identifying a low battery voltage threshold based on the temperature, measuring a first voltage level of the battery, commencing an operation sequence after measuring the first voltage level of the battery, generating a plurality of voltage comparisons between a reference voltage level and a voltage level delivered from the battery during the operation sequence, and generating, an output indicating a low battery condition if at least one of the first voltage level of the battery is less than the low battery voltage threshold and above a predetermined minimum operating voltage threshold, or at least one voltage comparison indicating the voltage level of the battery is less than the reference voltage level during the operation sequence.
