Abstract

Various embodiments include an energy storage apparatus for providing electrical energy comprising: a meter for capturing an electrical load profile to be provided and operating state values of energy storage devices; a data memory for storing data relating to an assessment profile for a respective energy storage device, wherein the assessment profile represents effects of operating parameters on a respective criterion of a respective energy storage device; a processor for dividing the electrical load profile into partial load profiles and assigning them to a respective energy storage device optimized based at least in part on the respective criterion and the respective operating state values; and an open-loop controller for operating the energy storage devices selected by the processor to jointly provide electrical power for the electrical load profile.

First claim

What is claimed is:

1. An apparatus for storing and providing electrical energy, the apparatus comprising:
a meter for capturing an electrical load profile and respective operating state values for each of a plurality of energy storage devices;
a data memory for storing data relating to a respective assessment profile for each of the plurality of energy storage devices, wherein each assessment profile represents effects of operating parameters on respective criteria for each of the plurality of energy storage devices;
a processor for dividing the electrical load profile into a plurality of partial load profiles and assigning one partial load profile of the plurality of partial load profiles to each of the plurality of energy storage devices, wherein the plurality of partial load profiles are assigned based on the respective assessment profile of each of the plurality of energy storage devices; and
a controller operating each of the plurality of energy storage devices using the assigned partial load profiles to jointly provide electrical power according to the electrical load profile.

2. The energy storage apparatus as claimed in claim 1 , wherein each energy storage device of the plurality of energy storage devices comprises a mechanical, physical and/or chemical energy storage device.

3. The energy storage apparatus as claimed in claim 1 , wherein each respective assessment profile comprises a matrix or a three-dimensional graph.

4. The energy storage apparatus as claimed in claim 1 , wherein the processor expands each of the respective assessment profiles in terms of number, scope, and/or degree of detail using values captured by the meter.

5. The energy storage apparatus as claimed in claim 1 , wherein additional assessment profiles are stored in the data memory.

6. The energy storage apparatus as claimed in claim 1 , wherein the respective criteria includes one or more factors selected from a group consisting of: service life, efficiency, energy density, power density, discharge time, and costs.

7. The energy storage apparatus as claimed in claim 1 , wherein the respective operating state values include one or more factors selected from a group consisting of: temperature, state of charge, humidity, pressure, radiation values, capacity, and power.

8. A method for using an energy storage apparatus to provide electrical energy, the method comprising:
capturing an electrical load profile and respective operating state values for each of a plurality of energy storage devices with a meter;
storing data relating to a respective assessment profile for each of the plurality of energy storage devices in a memory, wherein each respective assessment profile represents effects of respective operating parameters on respective criteria for each of the plurality of energy storage devices;
dividing the electrical load profile into a plurality of partial load profiles and assigning one partial load profile of the plurality of partial load profiles to each of the plurality of energy storage devices based on the respective assessment profile of each of the plurality of energy storage devices with a processor; and
controlling each of the plurality of energy storage devices using the assigned partial load profiles to jointly provide electrical power according to the electrical load profile.

9. The method as claimed in claim 8 , wherein at least one assessment profile of the assessment profiles is expanded in terms of number, scope, and/or degree of detail by the processor using values captured by the meter.

10. The method as claimed in claim 8 , further comprising storing additional assessment profiles in the memory.
