Abstract

A high voltage system for an electrified vehicle includes a first high voltage component, a second high voltage component, and a high voltage cable. The high voltage cable provides power between a first location of the first high voltage component and a second location of the second high voltage component. The high voltage cable includes a core, a sheath disposed around and along the core, and one or more detection layers at least one of (a) disposed around and along the sheath or (b) disposed within the sheath. The one or more detection layers are configured to facilitate detecting at least one of (a) damage or wear to the sheath or (b) a location of the damage or wear along the sheath.

First claim

The invention claimed is:

1 . A high voltage system for an electrified vehicle, the high voltage system comprising:
a first high voltage component; a second high voltage component; and a high voltage cable providing power between a first location of the first high voltage component and a second location of the second high voltage component, the high voltage cable including:
a core;
a sheath disposed around and along the core; and
one or more detection layers at least one of (a) disposed around and along the sheath or (b) disposed within the sheath;
wherein the one or more detection layers are configured to facilitate detecting damage or wear to the sheath;
wherein the one or more detection layers include a first layer and a second layer; and
wherein contact between the first layer and the second layer indicates the damage or wear to the sheath.

2 . The high voltage system of claim 1 , wherein the first layer is disposed within the sheath and the second layer is disposed around and along the sheath.

3 . The high voltage system of claim 1 , wherein the first layer is disposed around and along the sheath and the second layer is disposed around and along an exterior surface of the first layer.

4 . The high voltage system of claim 3 , wherein a separation material is positioned in a gap between the first layer and the second layer.

5 . The high voltage system of claim 1 , wherein the one or more detection layers are configured to facilitate detecting a location of the damage or wear along the sheath.

6 . The high voltage system of claim 5 , wherein the one or more detection layers include an indicator layer configured to provide a visual indicator at the location of the damage or wear along the sheath.

7 . A high voltage system for an electrified vehicle, the high voltage system comprising:
a first high voltage component; a second high voltage component; and a high voltage cable providing power between a first location of the first high voltage component and a second location of the second high voltage component, the high voltage cable including:
a core;
a sheath disposed around and along the core; and
one or more detection layers at least one of (a) disposed around and along the sheath or (b) disposed within the sheath;
wherein the one or more detection layers are configured to facilitate detecting damage or wear to the sheath;
wherein the one or more detection layers include a sleeve disposed around and along the sheath, the sleeve including interfaces positioned at opposing ends thereof; and
wherein the interfaces are configured to facilitate detecting a change in a resistance measurement across the sleeve.

8 . The high voltage system of claim 7 , wherein the one or more detection layers are configured to facilitate detecting the damage or wear to the sheath and a location of the damage or wear along the sheath.

9 . A high voltage system for an electrified vehicle, the high voltage system comprising:
a high voltage cable including:
a core;
a sheath disposed around and along the core; and
one or more detection layers at least one of (a) disposed around and along the sheath or (b) disposed within the sheath;
wherein the one or more detection layers are configured to facilitate detecting damage or wear to the sheath;
wherein the one or more detection layers include a first layer and a second layer; and
wherein contact between the first layer and the second layer indicates the damage or wear to the sheath.

10 . The high voltage system of claim 9 , wherein the first layer is disposed within the sheath and the second layer is disposed around and along the sheath.

11 . The high voltage system of claim 9 , wherein the first layer is disposed around and along the sheath and the second layer is disposed around and along an exterior surface of the first layer, and wherein a separation material is positioned in a gap between the first layer and the second layer.

12 . The high voltage system of claim 9 , wherein the one or more detection layers are configured to facilitate detecting a location of the damage or wear along the sheath.

13 . The high voltage system of claim 12 , the one or more detection layers include an indicator layer configured to provide a visual indicator at the location of the damage or wear along the sheath.

14 . A high voltage system for an electrified vehicle, the high voltage system comprising:
a high voltage cable including:
a core;
a sheath disposed around and along the core; and
one or more detection layers at least one of (a) disposed around and along the sheath or (b) disposed within the sheath;
wherein the one or more detection layers are configured to facilitate detecting damage or wear to the sheath;
wherein the one or more detection layers includes a sleeve disposed around and along the sheath, the sleeve including interfaces positioned at opposing ends of the sleeve; and
wherein the interfaces are configured to facilitate detecting a change in a resistance measurement across the sleeve.

15 . The high voltage system of claim 14 , wherein the one or more detection layers are configured to facilitate detecting the damage or wear to the sheath and a location of the damage or wear along the sheath.
