Electric Energy Storage Device and Method for Increasing the Voltage at the Storage Device Terminals

摘要

An electric energy storage device includes two electrical terminals. The energy storage device further includes at least one first current path configured to electrically connect to the two terminals. The energy storage device further includes at least two energy storage modules configured to be connected to form a series connection of the energy storage modules. The energy storage modules include multiple storage units and a controllable multiple-voltage level converter. The converter is configured to optionally connect the one or more storage units in the first current path for the incremental adjustment of a module voltage, as at least one of a function of a control signal of a control and regulating device of the electric energy storage device.
