Referring to figures 1-13, a battery pack assembly 100 of a vehicle is shown, in accordance with an embodiment of the present disclosure. The battery pack assembly 100 includes battery cell modules 10 mounted on the vehicle structure, and a wiring harness 20 connecting the battery cell modules 10. The battery pack assembly 100 comprises a frame 30 having weldments and an isolation means 40. The isolation means 40 is detachably attached to the frame 30, and positioned around the weldments to route the wiring harness 20 along the frame 30 and prevent the wiring harness 20 from rubbing against the weldments. The rubbing action can be observed in the figures 1 and 2 of the prior art in which the wiring harness 20 rubs against the weldment and the sharp corners of a welding seam 34. This rubbing action cause damage to the wiring harness 20 rendering the same inoperative in performing the intended function of monitoring the battery cell modules 10. The isolation means 40 includes bracket assemblies 40 configured to be attached to the members of the frame 30. Typically, the members of the frame 30 are in the form of channels that facilitate routing of the harness 20 therethrough. Each of the bracket assemblies 40 is positioned around a corresponding weldment, to route the wiring harness 20 along the frame 30 and prevent the wiring harness 20 from rubbing against the weldments. Each of the bracket assemblies 40 abuts a corresponding weldment so as to ensure protection for each weldment present on the frame 30. Each of the bracket assemblies 40 has a first set of side walls 43 abutting the weldment, and a second set of side walls 45 abutting a front face of cell module 10. The first set of side walls 43 and the second set of side walls 45 define at least one passage 48 there in between. The passages 48 defined between the first set of side walls 43 and the second set of side walls 45 facilitate routing of the harness 20 therethrough. Each of the bracket assemblies 40 includes a bracket 42 and a cover 44. The cover 44 is detachably attached to the bracket 42. The bracket 42 and the cover 44 has a first set of snap fitting elements 50 attached thereto. The first set of snap fitting elements 50 on the bracket 42 and the cover 44 engage and interlock with each other. The bracket (42) is snap fitted to the frame (30) with the help of a second set of snap fitting elements (60). Further, the cover 44 has lugs 70 configured thereon to facilitate securing the harness 20 in position and prevent any movement of the harness that would cause rubbing of the harness on adjacently located components. The lugs 70 abut the wiring harness for restricting movement of the wiring harness 20 caused due to vibrations experienced by the vehicle. The profile of the lugs 70 corresponds to the profile of the wiring harness 20.
In a preferred embodiment, the weldments include bosses 32 for mounting the battery pack assembly 100 to the vehicle. The bosses 32 are welded to the frame 30. A welding seam 34 is shown in the figure 2 of the prior art. The sharp corners of the welding seam 34 rub against the harness 20 and cause damage to the harness 20 making the harness 20 dysfunctional.
In a preferred embodiment, at least one of the bracket assemblies 100 is snap fitted to the frame 30, and the cover 44 is snap fitted to the bracket 42.
In another embodiment, the bosses 32 have shapes selected from the group consisting of a circle, a rectangle, or a polygon.
In an alternative embodiment, at least one of the bracket assemblies 40 is attached to the members of the frame 30 with the help of a bolted joint. Each of the brackets 42 is attached to the corresponding cover 44 with the help of a bolted joint.
