Systeme de stockage d'energie electrique

Electrical energy storage system

Abstract

The present invention relates to an apparatus for electrical power supplies and electrical storage systems. While conventional storage systems, for example batteries, offer very limited electrical properties, for example DC voltage with a voltage which is prespecified by the battery design and the state of charge, the invention can deliver virtually any desired current and voltage profiles within certain limits, for example a maximum voltage and a maximum current, without the need for a separate power-electronics converter circuit. At the same time, the invention can not only output but also receive energy in virtually any desired form and charge its integrated electrical energy stores, for example capacitors, batteries, rechargeable batteries and the like, while maintaining prespecified charging properties, for example specific current and voltage profiles or power output profiles over time (for example constant, increasing with a specific profile or falling with a specific profile).
