초록

Abnormal battery depletion can be detected in an implantable medical device. Battery capacity consumed can be measured using a coulometer and using a capacity-by-voltage device, and the measurements can be blended to determine battery status. A drop in battery voltage below a specified threshold can be detected to identify a high-current depletion fault, and an alarm can be provided to indicate the fault has been detected. The specified threshold can be determined as a function of battery capacity consumed. Other aspects and embodiments are provided here...

청구항

1. A system, comprising: a coulometer configured to measure battery capacity;a capacity-by-voltage device configured to use a sensed battery voltage to measure battery capacity;a controller, coupled to the coulometer and the capacity-by-voltage device, the controller configured to combine the measurements from the coulometer and the capacity-by-voltage device, using a weighted average of both of the measurements to determine battery capacity consumed, wherein a weight of each measurement in the weighted average is based on capacity remaining of the batte...
