Abstract

A vehicle includes a chassis, a body assembly, and a plurality of battery cells. The chassis includes a plurality of frame members. The body assembly is coupled to the plurality of frame members of the chassis. A bottom periphery of the body assembly is defined by a point at which the body assembly couples or contacts a top of the chassis. An uppermost periphery of the plurality of battery cells is spaced a distance below the bottom periphery of the body assembly. At least a portion of the plurality of battery cells extends lower than the plurality of frame members of the chassis.

First claim

The invention claimed is:

1. A vehicle comprising:
a chassis comprising a pair of longitudinal frame members;
a front axle coupled to the chassis;
a rear axle coupled to the chassis;
a cab coupled to the pair of longitudinal frame members;
a body assembly coupled to the pair of longitudinal members of the chassis rearward of the cab, a bottom periphery of the body assembly being defined by a point at which the body assembly couples or contacts a top of the chassis; and
an electric energy system including:
a first plurality of battery cells positioned forward of the rear axle and supported by the chassis, an uppermost periphery of the first plurality of battery cells (a) spaced a distance below the bottom periphery of the body assembly and (b) above a bottom of the pair of longitudinal frame members, wherein at least a portion of the first plurality of battery cells extends lower than the bottom of the pair of longitudinal frame members of the chassis; and
a second plurality of battery cells positioned separate from the first plurality of battery cells rearward of the rear axle and supported by the chassis in a different arrangement than the first plurality of battery cells, at least a portion of the second plurality of battery cells positioned at an elevated height relative to the first plurality of batteries such that an uppermost periphery of the second plurality of battery cells is positioned above the point at which the body assembly contacts the top of the chassis.

2. The vehicle of claim 1 , wherein the first plurality of battery cells are replaceable.

3. The vehicle of claim 1 , wherein the vehicle is fully powered by the electric energy system.

4. The vehicle of claim 1 , wherein the vehicle does not include an internal combustion engine.

5. The vehicle of claim 1 , wherein the electric energy system is configured to provide electrical energy to an electric actuator of the vehicle.

6. The vehicle of claim 1 , wherein the first plurality of battery cells are positioned within a housing, wherein an uppermost periphery of the housing is positioned lower than the bottom periphery of the body assembly, and wherein at least a portion of the housing extends lower than the pair of longitudinal frame members of the chassis.

7. The vehicle of claim 1 , wherein the first plurality of battery cells are positioned beneath the body assembly.

8. The vehicle of claim 1 , wherein the first plurality of battery cells are positioned on a forward portion of the chassis proximate the cab.

9. The vehicle of claim 1 , wherein the first plurality of battery cells are positioned at least partially laterally outwards of a lateral side of the chassis.

10. The vehicle of claim 1 , wherein the body assembly defines a refuse compartment.

11. A vehicle comprising:
a chassis including a pair of longitudinal frame members;
a front axle coupled to the chassis;
a rear axle coupled to the chassis;
a body assembly coupled to the pair of longitudinal frame members of the chassis; and
an electric energy system including:
a first plurality of battery cells positioned forward of the rear axle and supported by the chassis, an uppermost periphery of the first plurality of battery cells (a) spaced a distance below a point at which the body assembly contacts a top surface of the chassis and (b) above a bottom of the pair of longitudinal frame members, a lowermost periphery of the first plurality of battery cells extending below the bottom of the pair of longitudinal frame members of the chassis; and
a second plurality of battery cells positioned separate from the first plurality of battery cells rearward of the rear axle and supported by the chassis in a different arrangement than the first plurality of battery cells, at least a portion of the second plurality of battery cells positioned at an elevated height relative to the first plurality of batteries such that an uppermost periphery of the second plurality of battery cells is positioned above the point at which the body assembly contacts the top surface of the chassis.

12. The vehicle of claim 11 , wherein the vehicle is fully powered by the electric energy system, and wherein the vehicle does not include an internal combustion engine.

13. The vehicle of claim 11 , wherein the first plurality of battery cells are positioned at least partially laterally outwards of a lateral side of the chassis.

14. The vehicle of claim 11 , further comprising an electric motor coupled to the chassis, the electric motor powered by the electric energy system to drive the rear axle.

15. The vehicle of claim 11 , wherein the first plurality of battery cells are positioned in a housing, an uppermost periphery of the housing positioned lower than the point at which the body assembly contacts the top surface of the chassis, wherein at least a portion of the housing extends lower than the pair of longitudinal frame members of the chassis, and wherein the housing extends in a longitudinal direction along at least a portion of a length of the body assembly.

16. A vehicle comprising:
a chassis;
a front axle coupled to the chassis;
a rear axle coupled to the chassis;
an electric motor coupled to the chassis;
a cab coupled to the chassis;
a body coupled to the chassis;
a first battery pack supported by the chassis, the first battery pack configured to power the electric motor to drive at least one of the front axle or the rear axle, the first battery pack (a) positioned forward of the rear axle, (b) extending at least partially laterally outward of the chassis, (c) extending at least partially beneath a lowermost periphery of the chassis and the body, (d) spaced a distance beneath a point at which the body contacts the chassis, and (e) extending at least partially above the lowermost periphery of the chassis; and
a second battery pack positioned separate from the first battery pack rearward of the rear axle and supported by the chassis in a different arrangement than the first battery pack, at least a portion of the second battery pack positioned at an elevated height relative to the first battery pack such that an uppermost periphery of the second plurality of battery cells is positioned above the point at which the body contacts the chassis.
