Integrated flight battery cargo platform

1. A cargo platform comprising:

a housing having an exterior surface and a structural strength to support cargo for transit, the cargo placed on a top surface of the housing;

a battery enclosed in the housing with power contacts exposed at the exterior surface; and

wherein the power contacts comprise top power contacts exposed at the top surface and bottom power contacts exposed on a bottom surface of the housing and axially aligned with the top power contacts.

2. The cargo platform of claim 1 , wherein the power contacts comprise a positive contact, a negative contact, and a ground contact.

3. The cargo platform of claim 1 , wherein the power contacts are exposed at a side surface.

4. The cargo platform of claim 1 , wherein the power contacts are recessed into the housing.

5. The cargo platform of claim 1 , further comprising a balance connector exposed at the exterior surface, the balance connector coupled to the battery.

6. The cargo platform of claim 1 , further comprising a load sensor operable to measure a load on the top surface; and

a first electrical connector coupled to the load sensor, the first electrical connector exposed at the exterior surface of the housing and operable to communicate the load measured by the load sensor.

7. The cargo platform of claim 1 , further comprising a load sensor operable to measure a load on the top surface and electronics operable to determine a total weight and a center of gravity of the cargo platform; and

a first electrical connector exposed at the exterior surface and coupled to the electronics.

8. The cargo platform of claim 1 , wherein the top power contacts and the bottom power contacts each comprise a positive contact, a negative contact, and a ground contact.

9. The cargo platform of claim 1 , comprising:

a top balance connector coupled to the battery and exposed at the top surface; and

a bottom balance connector coupled to the battery and exposed at the bottom surface and axially aligned with the top balance connector.

10. The cargo platform of claim 1 , comprising:

a load sensor operable to measure a load on the top surface; and

a first electrical connector coupled to the load sensor, the first electrical connector exposed at the bottom surface of the housing and operable to communicate the load measured by the load sensor.

11. The cargo platform of claim 1 , further comprising a load sensor operable to measure a load on the top surface and electronics operable to determine a total weight and a center of gravity of the cargo platform; and

a first electrical connector coupled to the electronics and exposed at the bottom surface.

12. A method comprising:

disposing a cargo platform in a transportation vehicle, the cargo platform comprising a housing enclosing a battery with power contacts exposed at an exterior surface of the housing, cargo to be carried in transit by the transportation vehicle supported on a top surface of the housing;

coupling the battery via the power contacts to an electrical system of the transportation vehicle; and

the transportation vehicle carrying the cargo and the cargo platform in transit;

wherein:

the battery comprises top power contacts exposed at a top surface of the housing and bottom power contacts exposed on a bottom surface of the housing, the top power contacts and the bottom power contacts axially aligned;

the cargo platform is a first cargo platform positioned on the top surface of a second cargo platform thereby electrically connecting the bottom power contacts of the first cargo platform to the top power contacts of the second cargo platform; and

the bottom power contacts of the second cargo platform coupled to the electrical system of the transportation vehicle.

13. The method of claim 12 , wherein the transportation vehicle is an aircraft, and the electrical system is an electric propulsion system.

14. The method of claim 12 , further comprising electronically communicating a weight of the cargo platform to the transportation vehicle.

15. The method of claim 12 , wherein:

the transportation vehicle is a vertical takeoff and landing (VTOL) aircraft;

the electrical system is an electric propulsion system; and

the power contacts are exposed at a bottom surface of the housing and coupled to the electrical system through contacts on a floor of the VTOL aircraft.

16. The method of claim 12 , wherein the transportation vehicle is a vertical takeoff and landing aircraft, and the electrical system is an electric propulsion system.

17. The method of claim 16 , further comprising electronically communicating from the cargo platform to the transportation vehicle a weight of the cargo platform and the cargo.

18. The method of claim 12 , further comprising a non-conductive plate positioned between the cargo and the top power contacts of the first cargo platform.
