Abstract

An energy store tank assembly includes a tank adapted for mounting to a frame of a tractor-trailer vehicle by a mounting bracket. The mounting bracket is coupled to the frame, and the mounting bracket extends around, and in contact with, a circumference of the tank to secure the tank to the frame. The energy store tank assembly further includes an energy store disposed within the tank, the energy store configured to supply electrical power to the tractor-trailer vehicle in a first mode of operation and further configured to receive energy from the tractor-trailer vehicle in a second mode of operation. In some embodiments, the tank includes an electrical interface through which the energy store supplies the electrical power to the tractor-trailer vehicle in the first mode of operation and through which the energy store receives energy from the tractor-trailer vehicle in the second mode of operation.

First claim

What is claimed is:

1. A system comprising:
a vehicle including a communication interface coupled to a network, the communication interface configured to communicate with a remote transceiver; and
an energy store on the vehicle, the energy store configured to supply electrical power to the communication interface;
wherein the energy store comprises:
a tank housing mounted to a frame of the vehicle by a mounting bracket coupled to the frame, wherein the mounting bracket extends around, and in contact with, a circumference of the tank housing to secure the tank to the frame;
a battery pack disposed within the tank housing; and
an electrical interface through which the battery pack supplies the electrical power to the communication interface.

2. The system of claim 1 ,
wherein the battery pack is configured to supply electrical power to the vehicle in a first mode of operation and further configured to receive energy from the vehicle in a second mode of operation.

3. The system of claim 1 ,
wherein the electrical interface includes at least one high voltage connection and at least one low voltage connection; and
wherein the tank housing includes a plurality of coolant ports configured to provide for a flow of a coolant through the tank housing to cool the battery pack.

4. The system of claim 1 ,
wherein the tank housing includes a common wall configured to physically separate the tank housing into a first portion and a second portion,
wherein the first portion includes the battery pack; and wherein the second portion includes a diesel or alternative fuel portion.

5. The system of claim 1 ,
wherein the vehicle includes a tractor-trailer vehicle.

6. The system of claim 5 ,
wherein a trailer portion of the tractor-trailer vehicle includes an electrically powered drive axle configured to supply supplemental torque to one or more wheels of the trailer portion and to thereby supplement, while the trailer portion travels over a roadway and in at least some modes of operation, primary motive forces applied through a separate drivetrain powered by a fuel-fed engine of a tractor portion of the tractor-trailer vehicle; and
wherein the energy store is configured to supply the electrically powered drive axle with electrical power in the first mode of operation and is further configured to receive energy recovered using the electrically powered drive axle in the second mode of operation.

7. The system of claim 1 ,
wherein the energy store is configured to supply electrical power to an auxiliary power unit (APU) on the vehicle.

8. The system of claim 1 , further comprising:
a diesel or alternative fuel tank mounted adjacent to, and on a same side of the vehicle as, the tank housing of the energy store.

9. The system of claim 1 , wherein the energy store comprises:
a first tank adapted for mounting to a frame of the tractor-trailer vehicle by a first mounting bracket, wherein the first mounting bracket is coupled to the frame, and wherein the first mounting bracket extends around, and in contact with, a circumference of the first tank to secure the first tank to the frame; and
an energy store disposed within the first tank, the energy store configured to supply electrical power to the tractor-trailer vehicle in a first mode of operation and further configured to receive energy from the tractor-trailer vehicle in a second mode of operation;
wherein the first tank includes an electrical interface through which the energy store supplies the electrical power to the tractor-trailer vehicle in the first mode of operation and through which the energy store receives energy from the tractor-trailer vehicle in the second mode of operation.

10. The system of claim 1 , wherein the energy store tank assembly defines a substantially D-shaped housing.

11. The system of claim 1 , wherein the electrical interface includes at least one high voltage connection and at least one low voltage connection.

12. The system of claim 1 , further comprising a plurality of coolant ports configured to provide for a flow of a coolant through the energy store tank assembly.

13. The system of claim 12 , wherein the coolant includes a liquid coolant or an air coolant.

14. The system of claim 1 , further comprising:
a second tank adapted for mounting to the frame of the tractor-trailer vehicle by a second mounting bracket, wherein the second mounting bracket is coupled to the frame, and wherein the second mounting bracket extends around, and in contact with, a circumference of the second tank to secure the second tank to the frame;
wherein the second tank is mounted adjacent to, and on a same side of the tractor-trailer vehicle as, the first tank.

15. The system of claim 14 , wherein the second tank includes a diesel or alternative fuel tank.

16. The system of claim 9 , wherein
the first tank includes a common wall configured to physically separate the first tank into a first portion and a second portion,
the first portion includes the energy store; and
the second portion includes a diesel or alternative fuel portion.

17. The system of claim 9 ,
wherein the first tank is mounted to a first lateral side of the tractor-trailer vehicle, and
wherein the energy store tank assembly further comprises:
a second tank adapted for mounting to the frame of the tractor-trailer vehicle by a second mounting bracket, wherein the second mounting bracket is coupled to the frame, and
wherein the second mounting bracket extends around, and in contact with, a circumference of the second tank to secure the second tank to the frame; wherein the second tank is mounted to a second lateral side of the tractor-trailer vehicle opposite the first lateral side.

18. The system of claim 17 , wherein the first tank includes a first common wall configured to physically separate the first tank into a first portion and a second portion,
wherein the second tank includes a second common wall configured to physically separate the second tank into a third portion and a fourth portion,
wherein the first portion includes the energy store;
wherein the second portion includes a first diesel or alternative fuel portion;
wherein the third portion includes another energy store; and
wherein the fourth portion includes a second diesel or alternative fuel portion.

19. The system of claim 9 , wherein a trailer portion of the tractor-trailer vehicle includes an electrically powered drive axle configured to supply supplemental torque to one or more wheels of the trailer portion and to thereby supplement, while the trailer portion travels over a roadway and in at least some modes of operation, primary motive forces applied through a separate drivetrain powered by a fuel-fed engine of a tractor portion of the tractor-trailer vehicle;
wherein the energy store is configured to supply the electrically powered drive axle with electrical power in the first mode of operation and is further configured to receive energy recovered using the electrically powered drive axle in the second mode of operation.

20. The system of claim 9 , wherein the energy store is configured to supply electrical power to an auxiliary power unit (APU) on the tractor-trailer vehicle.
