Abstract

A system includes a vehicle including a motive electrical power path; a power distribution unit including: a current protection circuit disposed in the motive electrical power path, the current protection circuit including a fuse and a contactor in a series arrangement with the fuse; a high voltage power input coupling including a first electrical interface for a high voltage power source; and a high voltage power output coupling including a second electrical interface for a motive power load, where the current protection circuit electrically couples the high voltage power input coupling to the high voltage power output coupling.

Claims (14)

1. A system, comprising:

a power distribution unit comprising:

a current protection circuit for a motive electrical power path of a vehicle, the current protection circuit comprising a fuse and a contactor in a series arrangement with the fuse;

a high voltage power input coupling comprising a first electrical interface for a high voltage power source; and

a high voltage power output coupling comprising a second electrical interface for a motive power load,

wherein the current protection circuit electrically couples the high voltage power input coupling to the high voltage power output coupling.

2. The system of claim 1 , wherein the fuse includes a current rating that is higher than a current corresponding to a rated power throughput of the motive electrical power path.

3. The system of claim 2 , wherein the fuse is sized to avoid wear or degradation up to the rated power throughput.

4. The system of claim 3 , wherein the fuse is sized to accommodate a higher power rating than a power rating of the vehicle.

5. The system of claim 3 , wherein, a current corresponding to the rated power throughput of the motive electrical power path corresponds to a nominal voltage of the motive electrical power path.

6. The system of claim 3 , wherein, a current corresponding to the rated power throughput of the motive electrical power path corresponds to a current at a degraded or failure mode voltage of the motive electrical power path.

7. The system of claim 1 , wherein the fuse includes a current rating that is higher than a current corresponding to a quick charging power throughput of the motive electrical power path.

8. The system of claim 1 , wherein the contactor includes a current rating that is higher than a current corresponding to a rated power throughput of the motive electrical power path.

9. The system of claim 1 , wherein the contactor includes a current rating that is higher than a current corresponding to a quick charging power throughput of the motive electrical power path.
