Abstract
The method and system manage power supplied from a charging circuit to a power source in an implantable medical device utilizing measurements of current drain; measurements of elapsed time since the last full charge; calculations of operating time based on the variable of current drain and the variable of the actual capacity of the power source; sensing of voltage level above a certain value; and monitoring of the temperature of the power source during charging and discharging.
