Title
(EN) Method and device for determining the state of charge of a battery
(ZH) 用于确定电池的充电状态的方法和设备
Abstract
(EN)
For medical implants it is not only important to have a battery powering the implant with a long run-time, but to know exactly at any point in time how long the remaining run-time is. On the other hand the implant together with its battery shall be as user- friendly as possible requiring no or hardly any interaction with the device except for recharging of the battery. To better address these concerns, a method for determining the state of charge of a battery is suggested comprising the steps: charging the battery, discharging of the battery, predicting the state of charge of the battery usinga recharge prediction unit, wherein the recharge prediction unit is disconnected from the battery during the discharging of the battery. The prediction of the state of charge of the battery during the discharge of the battery, i.e. during powering of a device connected to the battery, without carrying out any measurements during the discharging of the battery, enables a local separation of the battery or the implant powered by the battery and the recharge prediction unit during the discharge cycle of the battery.

对于医疗植入物,重要的是不仅具有向具有长运行时间的植入物供电的电池,而且准确地知道在时间中任何点处剩余运行时间是多长。在另一方面,植入物及其电池应该尽可能用户友好,不需要或者几乎不需要任何与设备的交互,除了对电池再充电。为了更好地解决这些所关心的问题,提出了用于确定电池的充电状态的方法,其包括以下步骤:对电池充电,电池放电,使用再充电预测单元预测电池的充电状态,其中,在电池放电期间,将再充电预测单元与电池断开。在电池放电期间(即,在向与电池连接的设备供电期间)预测电池的充电状态不需要在电池放电期间执行任何测量,从而使得在电池放电周期期间电池或者由电池供电的植入物能够与再充电预测单元局部分离。
