Abstract

An electrified vehicle includes a front subframe, a rear subframe, and a body that connects the front subframe to the rear subframe so that forces acting on the front subframe and the rear subframe are transmitted through the body. The vehicle also includes a housing coupled to an underside of the body between the front subframe and the rear subframe. An energy storage system is enclosed in the housing and includes a battery and a battery interface configured to electrically couple the battery to at least one component of the electrified vehicle.

First claim

What is claimed is:

1. An electrified vehicle, comprising:
a front subframe;
a rear subframe;
a body that connects the front subframe to the rear subframe so that forces acting on the front subframe and the rear subframe are transmitted through the body;
a housing coupled to an underside of the body between the front subframe and the rear subframe; and
an energy storage system enclosed within the housing and comprising:
a battery; and
a battery interface configured to electrically couple the battery to at least one component of the electrified vehicle,

wherein the body comprises at least one of a refuse compartment, a lift assembly, a mixing drum assembly, a ladder assembly, a pump system, or a turntable.

2. The electrified vehicle of claim 1 , further comprising:
a front tractive element attached to the front subframe;
a rear tractive element attached to the rear subframe; and
a drive motor electrically coupled to the energy storage system configured to drive at least one of the front tractive element or the rear tractive element.

3. The electrified vehicle of claim 1 , wherein the body is directly coupled to the front subframe and the rear subframe such that stresses are transferred between the front and rear subframes.

4. The electrified vehicle of claim 1 , wherein the body comprises a refuse compartment and a lift assembly configured to selectively extend from the body.

5. The electrified vehicle of claim 1 , further comprising:
a plurality of barriers coupled to the body,
wherein at least one of the plurality of barriers faces a first side of the housing and at least one of the plurality of barriers faces a second side of the housing opposite the first side,
wherein at least one of the plurality of barriers is movable to provide access to at least one of the first side or the second side of the energy storage system.

6. The electrified vehicle of claim 1 , wherein the housing is coupled to the body via a three-point connection or a four-point connection.

7. The electrified vehicle of claim 1 , wherein the housing is coupled to the body via at least one pivot point at least partially composed of rubber.

8. The electrified vehicle of claim 1 , wherein the mounting system comprises:
a first plurality of pivot mounts rotatably coupling the housing to the body such that the housing is rotatable around a first axis; and
a second plurality of pivot mounts rotatable coupling the housing to the body such that the housing is rotatable around a second axis orthogonal to the first axis.

9. The electrified vehicle of claim 1 , wherein the mounting system comprises:
a pivot mount rotatably coupling the housing to the body such that the housing is rotatable around a longitudinal axis; and
a plurality of fixed mounts coupling the housing to the body, wherein the plurality of fixed mounts are spaced longitudinally a distance apart from the pivot mount with at least one of the plurality of fixed mounts on a left side of the electrified vehicle and at least one of the plurality of fixed mounts on a right side of the electrified vehicle.

10. An electrified vehicle comprising:
a front subframe;
a rear subframe;
a body that connects the front subframe to the rear subframe so that forces acting on the front subframe and the rear subframe are transmitted through the body:
a housing coupled to an underside of the body between the front subframe and the rear subframe;
an energy storage system enclosed within the housing and comprising:
a battery; and
a battery interface configured to electrically couple the battery to at least one component of the electrified vehicle,

a first barrier removably coupled to the body on a first lateral side of the housing; and
a second barrier removably coupled to the body on a second lateral side of the housing opposite the first lateral side, the first and second barriers positioned longitudinally between the front subframe and the rear subframe.

11. The electrified vehicle of claim 10 , wherein at least one of the first barrier and the second barrier is removeable to provide access to at least one of the first lateral side or the second lateral side of the housing.

12. An electrified vehicle, comprising:
a chassis comprising:
a front subframe;
a rear subframe; and
a body that directly couples the front subframe to the rear subframe;

a tractive element supported by the chassis;
a drive motor supported by the chassis and coupled to the tractive element to rotate the tractive element;
a housing coupled to the body between the front subframe and the rear subframe, the housing comprising a battery, wherein the battery is electrically coupled to the drive motor;
a first wall coupled to the body on a first lateral side of the housing; and
a second wall coupled to the body on a second lateral side of the housing opposite the first lateral side, the first and second walls positioned longitudinally between the front subframe and the rear subframe,
wherein at least one of the first wall and the second wall is movable to provide access to at least one of the first side or the second side of the housing.

13. The electrified vehicle of claim 12 , wherein the housing is removably coupled to an underside of the body between the front subframe and the rear subframe.

14. The electrified vehicle of claim 12 , wherein the body comprises at least one of a refuse compartment, a lift assembly, a mixing drum assembly, a ladder assembly, a pump system, or a turntable.

15. The electrified vehicle of claim 12 , wherein the body comprise a refuse compartment and a lift assembly configured to selectively extend from the body.

16. The electrified vehicle of claim 12 , wherein the housing is removable from the body when the body is coupled to the front subframe and the rear subframe.

17. The electrified vehicle of claim 12 , wherein body directly couples the front subframe to the rear subframe so that forces acting on the front subframe and the rear subframe are transmitted through the body.

18. The electrified vehicle of claim 12 , wherein the housing is removably coupled to the body via a plurality of attachment points, wherein each of the plurality of attachment points is accessible from an exterior of the electrified vehicle.

19. The electrified vehicle of claim 12 , wherein the housing is coupled to the body via a first pivot mount and a first fixed mount.

20. An electrified vehicle, comprising:
a chassis comprising:
a front subframe;
a rear subframe; and
a body that directly couples the front subframe to the rear subframe;

a tractive element supported by the chassis;
a drive motor supported by the chassis and coupled to the tractive element to rotate the tractive element;
