METHOD AND APPARATUS FOR MONITORING BATTERY STATUS OF IMPLANTABLE MEDICAL DEVICE
First Claim
Patent Images
1. A method for monitoring status of a battery in an implantable medical device, the method comprising:
- measuring values of a battery functional parameter indicative of a state of depletion of the battery, the measured values each indicative of an actual state of depletion of the battery;
calculating values of the battery functional parameter each as a function of one or more specification parameters of the battery and one or more parameters indicative of energy consumption from the battery, the calculated values each indicative of an expected state of depletion of the battery;
producing a measured battery status trend being a trend of the measured values of the battery functional parameter and a calculated battery status trend being a trend of the calculated values of the battery functional parameter.

Abstract
A battery monitoring system monitors status of a battery in an implantable medical device by comparing a measured battery status trend to a calculated battery status trend. The measured battery status trend is a trend of measured parameter values each indicative of an actual state of depletion of the battery. The calculated battery status trend is a trend of calculated parameter values each indicative of an expected state of depletion of the battery.
