Abstract

A vehicle includes a chassis including a frame rail extending longitudinally, a tractive element coupled to the chassis, a cab coupled to the chassis and configured to support an operator, an electric motor configured to drive the tractive element to propel the vehicle, a battery configured to supply electrical energy to the electric motor, a heat exchanger, a cable electrically coupling the electric motor and the battery, and a conduit fluidly coupling the battery and the heat exchanger. The cable and the conduit extend laterally from the battery to the frame rail, and the cable and the conduit extend longitudinally along the frame rail.

First claim

1 . A vehicle comprising:
a chassis including a frame rail extending longitudinally; a tractive element coupled to the chassis; a cab coupled to the chassis and configured to support an operator; an electric motor configured to drive the tractive element to propel the vehicle; a battery configured to supply electrical energy to the electric motor; and at least one cable electrically coupling the electric motor and the battery; wherein a first section of the at least one cable extends laterally between the battery and the frame rail, and wherein a second section of the at least one cable extends longitudinally along the frame rail.

2 . The vehicle of claim 1 , wherein the battery is a first battery and the electrical energy is first electrical energy, further comprising a second battery configured to supply second electrical energy to the electric motor, wherein a third section of the at least one cable extends laterally between the second battery and the frame rail.

3 . The vehicle of claim 2 , wherein the first section of the at least one cable extends in a first lateral direction from the first battery toward the frame rail, wherein the second section of the at least one cable extends in a second lateral direction from the first battery toward the frame rail, and wherein the first lateral direction is opposite the second lateral direction.

4 . The vehicle of claim 1 , further comprising a power distribution unit configured to electrically couple the battery to the electric motor and a secondary electrical load, wherein the power distribution unit is positioned forward of the battery, and wherein the second section of the at least one cable extends longitudinally between the battery and the power distribution unit.

5 . The vehicle of claim 1 , wherein the battery is a first battery and the electrical energy is first electrical energy, further comprising:
a second battery configured to supply second electrical energy to the electric motor; and a housing coupled to the chassis and containing the first battery and the second battery.

6 . The vehicle of claim 5 , wherein the housing includes a wall, wherein the at least one cable extends within the housing between the wall and the first battery, and wherein the wall is removable to facilitate access to the at least one cable from outside of the housing.

7 . The vehicle of claim 6 , wherein the first section of the at least one cable extends within the housing between the wall and the first battery, and wherein the wall is removable to facilitate access to the first section of the at least one cable from outside of the housing.

8 . The vehicle of claim 6 , wherein the housing includes a top panel defining a top surface of the housing and a bottom panel defining a bottom surface of the housing, and wherein the wall extends between the top panel and the bottom panel of the housing.

9 . The vehicle of claim 1 , wherein the frame rail is a first frame rail, wherein the chassis further includes a second frame rail extending longitudinally, and wherein the second section of the at least one cable extends between the first frame rail and the second frame rail.

10 . A vehicle comprising:
a chassis including a frame rail extending longitudinally; a tractive element coupled to the chassis; a cab coupled to the chassis and configured to support an operator; an electric motor configured to drive the tractive element to propel the vehicle; a battery configured to supply electrical energy to the electric motor; a radiator; a fan positioned to force air through the radiator; and a conduit fluidly coupling the battery and the radiator, wherein a first conduit extends laterally from the battery to the frame rail, and
wherein a second conduit extends longitudinally along the frame rail.

11 . The vehicle of claim 10 , wherein the battery is a first battery and the electrical energy is first electrical energy, further comprising a second battery configured to supply second electrical energy to the electric motor, wherein a third conduit extends laterally between the second battery and the frame rail.

12 . The vehicle of claim 11 , wherein the first conduit and the third conduit are each directly fluidly coupled to the second conduit.

13 . The vehicle of claim 10 , wherein the radiator is positioned forward of the battery, and wherein the second conduit extends longitudinally between the first conduit and the radiator.

14 . The vehicle of claim 13 , wherein the radiator is coupled to the cab and positioned above a top surface of the cab.

15 . The vehicle of claim 10 , wherein the battery is a first battery and the electrical energy is first electrical energy, further comprising:
a second battery configured to supply second electrical energy to the electric motor; and a housing coupled to the chassis and containing the first battery and the second battery.

16 . The vehicle of claim 15 , wherein the housing includes a top panel defining a top surface of the housing, and wherein the first conduit extends along the top surface of the housing.

17 . The vehicle of claim 16 , further comprising a bulkhead fitting extending through the top panel and fluidly coupling the first battery to the first conduit.

18 . The vehicle of claim 10 , wherein the frame rail is a first frame rail, wherein the chassis further includes a second frame rail extending longitudinally, and wherein the second conduit extends along an outer surface of the first frame rail such that the first frame rail extends between the second conduit and the second frame rail.

19 . A vehicle comprising:
a chassis including a frame rail extending longitudinally; a tractive element coupled to the chassis; a cab coupled to the chassis and configured to support an operator; an electric motor configured to drive the tractive element to propel the vehicle; a battery configured to supply electrical energy to the electric motor; a heat exchanger; a cable electrically coupling the electric motor and the battery; and a conduit fluidly coupling the battery and the heat exchanger, wherein the cable and the conduit extend laterally from the battery to the frame rail, and wherein the cable and the conduit extend longitudinally along the frame rail.

19 . The vehicle of claim 19 , wherein the cable and the conduit extend laterally inward from the battery to the frame rail.
