摘要： A method for determining a recovery voltage in a battery includes detecting a transient increased current draw event drawing current from the battery, the transient increased current draw event starting at a start time and ending at an end time; and in response to detecting the transient increased current draw event, waiting until time and/or voltage criteria are met to determine recovered battery voltage. An implantable pulse generator (PG) device for stimulating a human organ includes a battery, a power sink drawing current from the battery, wherein drawing increased current from the battery for transient periods causes battery voltage to decrease; and a status indicator detecting a transient increased current draw event and waiting a minimum time duration after the transient increased current draw event to measure battery voltage in order to determine a recovery voltage.

摘要： It is an object of the present invention to provide a battery remaining amount warning circuit capable of issuing a battery remaining amount warning after battery power is fully used, consuming less power and issuing a warning at appropriate timing for various types of battery. The A/D converter measures a voltage value of the battery and when the voltage value of the battery falls to a specified level due to consumption, etc., of the battery, the A/D converter intermittently feeds the dummy-load circuit with a difference current representing a difference between a current value in a specific operating mode and a current value in another operating mode, measures the voltage of the battery and detects a voltage drop of the battery. When the difference current flows into the dummy-load circuit, a load applies to the battery the moment the current flows, causing a voltage drop.
