Patent attributes
The invention relates to a device consisting of a storage device for storing electrical energy. This may, for example, be a battery, an accumulator or another electrical storage device, for example a capacitor (double-layer capacitor). In the present application, the object is now pursued of keeping the consumption of electrical energy as low as possible, to economize relative to previous solutions and to bring about a great simplification from the point of view of manufacturing. Device consisting of a storage device for storing electrical energy, a device for monitoring the output current from the storage device and a controllable switch, by means of which the current output can be interrupted, wherein the switch is opened and the current output is therefore interrupted, when the device for monitoring the output current detects that for a predetermined time, for example, 30 seconds to 2 minutes, a predetermined current characteristic is present, for example, the output current does not fluctuate, or only extremely slightly.
