Abstract

A system for dynamic excitation of an energy storage element configured for use in an electric aircraft includes a plurality of propulsors mechanically connected to the electric aircraft. The system includes a plurality of energy storage elements electrically connected to the plurality of propulsors. The system includes a bus element, wherein the bus element is electrically connected to the plurality of energy storage elements and a cross tie element connected to the bus element configured to disconnect a first energy storage element from a second energy storage element. The system includes a modulator unit electrically connected to the bus element configured to modulate a first electrical command to the first energy storage element and a second electrical command to the second energy storage element. The system includes at least a sensor configured to detect an energy datum corresponding to the first energy storage element as a function of the modulation.

Claims (29)

1. A system for dynamic excitation of an energy storage element configured for use in an electric aircraft, the system comprising:

a plurality of propulsors mechanically connected to the electric aircraft;

a plurality of energy storage elements electrically connected to the plurality of propulsors;

a bus element, wherein the bus element is electrically connected to the plurality of energy storage elements; and

a cross tie element, the cross tie element connected to the bus element and configured to disconnect a first energy storage element of the plurality of storage elements from a second energy storage element of the plurality of storage elements, wherein the first storage element is electrically connected to a first propulsor element incorporated in the plurality of propulsors and the second energy storage element is electrically connected to a second propulsor element incorporated in the plurality of propulsors.

2. The system of claim 1 , wherein the cross tie element comprises at least a switch.

3. The system of claim 1 , wherein the plurality of energy storage elements comprises a battery module.

4. The system of claim 1 , further comprising a modulator unit electrically connected to the bus element, the modulator unit configured to modulate a first electrical command to the first propulsor element and a second electrical command to the second propulsor element.

5. The system of claim 4 , wherein modulating the first electrical command and second electrical command comprises drawing electrical energy from the first energy storage element.

6. The system of claim 4 , wherein the modulator unit is further configured to measure at least an electrical parameter as a function of the modulation of the first electrical command.

7. The system of claim 6 , wherein measuring the electrical parameter further comprises detecting a change in the electrical parameter.

8. The system of claim 1 , wherein the bus element comprises a ring bus.

9. The system of claim 1 , wherein the cross tie element is configured to:

receive a datum from at least a sensor; and

disconnect the first energy storage element from the second energy storage element as a function of the datum.

10. The system of claim 9 , wherein the energy datum comprises a health datum.

11. A method for dynamic excitation of an energy storage element configured for use in electric aircraft, the method comprising:

disconnecting, by a cross tie element connected to a bus element, a first energy storage element electrically connected to the bus element from a second energy storage element electrically connected to the bus element, wherein the first storage element is electrically connected to a first propulsor element incorporated in a plurality of propulsors and the second energy storage element is electrically connected to a second propulsor element incorporated in the plurality of propulsors.

12. The method of claim 11 , wherein cross tie element comprises a switch.

13. The method of claim 11 , wherein the energy storage element comprises a battery module.

14. The method of claim 11 , wherein the modulator unit comprises a processor.

15. The method of claim 14 , wherein modulating the first electrical command and second electrical command comprises drawing electrical energy from the first energy storage element.

16. The method of claim 15 , wherein measuring the electrical parameter further comprises detecting a change in the electrical parameter.

17. The method of claim 14 , wherein the modulator unit is further configured to measure at least an electrical parameter as a function of the modulation of the first electrical command.

18. The method of claim 11 , further comprising modulating, by a modulator unit, a first electrical command to the first propulsor element and a second electrical command to the second propulsor element.

19. The method of claim 11 , wherein the cross tie element is configured to:

receive a datum from at least a sensor; and

disconnect the first energy storage element from the second energy storage element as a function of the datum.

20. The method of claim 19 , wherein the energy datum comprises a health datum.
