Methods and apparatus for trailers with adjustable batteries

1. A trailer to be coupled to a first vehicle comprising:

a platform;

one or more wheels;

a battery disposed at a first location relative to the platform;

a drive to move the battery relative to the platform; and

a controller to:

determine a first load distribution on the platform by:

determining a first portion of a load of the trailer transferred to the first vehicle via a tongue coupled to the first vehicle; and

determining a second portion of the load of the trailer carried via the one or more wheels; and

in response to determining the first load distribution on the platform does not satisfy a first threshold, adjust a position of the battery, via the drive, to a second location relative to the platform.

2. The trailer of claim 1 , wherein the first threshold is based on the first portion being between 10% and 15% of the load.

3. The trailer of claim 1 , wherein the controller is further to:

in response to moving the battery to the second location, determine a second load distribution;

determine if the second load distribution satisfies the first threshold; and

in response to determining the second load distribution does not satisfy the first threshold, generating an alert to a user of the first vehicle, the alert including an indication to move an object disposed on the platform.

4. The trailer of claim 3 , wherein the controller is to generate the alert by displaying the indication via a lamp of the first vehicle.

5. The trailer of claim 1 , wherein the controller is further to:

detect, via a first sensor, during operation of the first vehicle, a first event; and

move, via the drive, the battery to a third position in response to detecting the first event.

6. The trailer of claim 5 , wherein the first event includes a second vehicle passing the first vehicle.

7. The trailer of claim 5 , wherein the first event satisfies a second threshold associated with decreasing stability of the platform.

8. A non-transitory computer readable medium comprising instructions, which when executed, cause a processor to:

determine a first load distribution on a platform of a trailer coupled to a first vehicle, the determination of the first load distribution including:

determine a first portion of a load of the trailer transferred to the first vehicle via a tongue coupled to the first vehicle; and

determine a second portion of the load of the trailer carried via one or more wheels of the first vehicle; and

in response to determining the first load distribution does not satisfy a first threshold, move, via a drive, a battery coupled to the platform from a first location to a second location.

9. The non-transitory computer readable medium of claim 8 , wherein the first threshold is based on the first portion being between 10% and 15% of the load.

10. The non-transitory computer readable medium of claim 8 , wherein the instructions, when executed, cause the processor to:

in response to moving the battery to the second location, determine a second load distribution;

determine if the second load distribution satisfies the first threshold; and

in response to determining the second load distribution does not satisfy the first threshold, generating an alert to a user of the first vehicle, the alert including an indication to move an object disposed on the platform.

11. The non-transitory computer readable medium of claim 10 , wherein the instructions, when executed, cause the processor to generate the alert by displaying the indication via a lamp of the first vehicle.

12. The non-transitory computer readable medium of claim 8 , wherein the instructions, when executed, cause the processor to:

detect, via a first sensor, during operation of the first vehicle, a first event; and

move, via the drive, the battery to a third position in response to detecting the first event.

13. The non-transitory computer readable medium of claim 12 , wherein the first event includes a second vehicle passing the first vehicle.

14. The non-transitory computer readable medium of claim 12 , wherein the first event satisfies a second threshold associated with decrease stability of the platform.

15. A method including:

determining a first load distribution on a platform of a trailer coupled to a first vehicle, the determining the first load distribution including:

determining a first portion of a load of the trailer transferred to the first vehicle via a tongue coupled to the first vehicle; and

determining a second portion of the load of the trailer carried via one or more wheels of the first vehicle; and

in response to determining the first load distribution does not satisfy a first threshold, moving, via a drive, a battery coupled to the platform from a first location to a second location.

16. The method of claim 15 , further including:

in response to moving the battery to the second location, determining a second load distribution;

determining if the second load distribution satisfies the first threshold; and

in response to determining the second load distribution does not satisfy the first threshold, generating an alert to a user of the first vehicle, the alert including an indication to move an object disposed on the platform.

17. The method of claim 15 , further including:

detecting, via a first sensor, during operation of the first vehicle, a first event; and

moving, via the drive, the battery to a third position.

18. The method of claim 17 , wherein the first event includes a second vehicle passing the first vehicle.

19. The method of claim 17 , wherein the first event satisfies a second threshold associated with decreasing stability of the platform.

20. The method of claim 15 , wherein the first threshold is based on the first portion being between 10% and 15% of the load.
