摘要:
A secondary electrochemical cell with at least one positive electrode includes an active material and one negative electrode, which are held directly in a hermetically tight housing which has at least one detector element or which is dynamically connected to one such detector element. The detector element is designed or can be set to acquire a predetermined unallowable operating state of the secondary electrochemical cell, and in an unallowable operating state of the secondary electrochemical cell, to actuate at least one switching element which prevents recharging and/or discharging of the secondary electrochemical cell. By making the housing as a hermetically tight protective housing, which is part of an implantable medical device, contamination of surrounding tissue with toxic substances and hazard to the implant wearer by the malfunction of the secondary electrochemical cell can be precluded under all operating conditions with simultaneously great reduction of all dimensions.
摘要:
The invention relates to an implantable medical device having an hermetically tight housing, which houses an electronic unit as well as an electrochemical energy storage for supplying the medical device with current. The energy storage is arranged directly within the hermetically tight housing without having a separate housing.
摘要:
A device for operating a rechargeable storage for electrical energy, comprising a charging module for providing electric power to charge the storage; a data acquisition module for continually acquiring instantaneous operating parameters of the storage during operation; a prediction module having implemented an adaptive model for deriving from data describing a state of the storage before start-up and data acquired in operation and optionally acquired from other expert knowledge predictions about future states of the storage, the model being operable to be automatically optimized continuously using data acquired in operation and optionally using further expert knowledge; a data memory, and a control module for controlling the charging module, the control module being operable to choose an instantaneous charging strategy for the storage depending on predictions derived from the model and on currently acquired operating parameters of the storage. Furthermore the invention relates to a process for operating a rechargeable storage for electrical energy.
