Abstract
Official abstract text for this publication.
The invention relates to an energy storage device for generating an n-phase supply voltage for an electrical machine, where n≧1, or for an inverter, with n energy supply branches connected in parallel, each of which can be connected to one of n phase lines, each of the energy supply branches comprising a plurality of series-connected energy storage modules, each comprising: an energy storage cell module and a coupling device configured to selectively connect the energy storage cell module into the respective energy supply branch or to bypass said module, the energy storage cell modules of respective first energy storage modules of an energy supply branch each comprising at least one first energy storage cell, the energy storage cell modules of respective second energy storage modules of an energy supply branch each comprising at least one second energy storage cell, and the first energy storage cells having a lower internal resistance than the second energy storage cells below a predetermined temperature threshold.
First claim
Opening claim text (preview).
The invention claimed is: 1. An energy storage device for generating an n-phase supply voltage for an electric machine, wherein n≧1, or for an inverter, the energy storage device comprising: n energy supply branches which are connected in parallel and which are each connectable to one of n phase lines, wherein each of the energy supply branches has a large number of energy storage modules which are connected in series and which each comprise: an energy storage cell module, and…
