Method and circuit for determining the battery status in a medical implant
摘要：
In a method and an apparatus for detecting the status of a battery in an implantable heart stimulator, the battery impedances measured and an increased value of the measured impedance is detected, from which an impedance based value of the remaining battery capacity is determined. The increase in impedance is analyzed to determine whether the impedance increase is a reliable indicator of the remaining battery capacity. If it is determined that the impedance increase is not reliable for determining the battery capacity, the total charge depletion of the battery is measured and a charge depletion-based value of the remaining battery capacity is determined.
摘要（中）：

在用于检测可植入心脏刺激器中的电池的状态的方法和装置中，检测电池阻抗并检测测量阻抗的增加的值，从而确定剩余电池容量的基于阻抗的值。 分析阻抗的增加以确定阻抗增加是否是剩余电池容量的可靠指标。 如果确定阻抗增加对于确定电池容量是不可靠的，则测量电池的总电荷消耗，并且确定剩余电池容量的基于电荷消耗的值。
