<p>A system and method of monitoring the amount of charge consumed from a battery powering a device, e.g., an implantable medical device, operable in at least first and second current drain states are disclosed. In each drain state, the duration of the state is timed out as a state time. At each state change, the state time is added to cumulative state time for the current drain state. A cumulative charge drawn from the battery in each current drain state can be calculated as a function of the state current drain and the cumulative state time for the current drain state. The amount of charge consumed from the battery is represented by the cumulative charge drawn in all of the current drain states. The calculations of the amount of charge consumed can take place in the implantable medical device or in an external medical device interrogating data stored in the implantable medical device.</p> |
