ELECTRICAL ENERGY-STORAGE UNIT WITH STORAGE MODULES OF DIFFERENT TYPES

摘要

The invention relates to an electrical energy-storage unit (3) having a plurality of electrically coupled and interchangeable storage modules (1, 2) each with a multiplicity of storage cells (5) connected in series or in parallel, wherein the energy-storage unit (3) has storage modules (1) of a first type, which have a certain energy density, wherein the energy-storage unit (3) has storage modules (2) of a second type which have a higher energy density than the storage modules (1) of the first type, and at least two storage modules (2) of the second type fit into the spatial volume of a storage module (1) of the first type. The invention also relates to a motor vehicle having such an energy-storage unit.
