Management system embedded in an industrial vehicle

1. A system for transmitting data between components of an industrial vehicle that are powered by electricity received through a power line, said system comprising:

a first electrical choke, wherein a conductor is arranged to pass through the first electrical choke and to connect a first component to the power line; and

a first communication circuit for at least one of sending and receiving signals and having a transmission wire for carrying the signals, wherein the transmission wire passes through the first electrical choke and is electrically attached to the conductor at a point between the first electrical choke and the first component, and

wherein when the first communication circuit transmits a communication signal, the communication signal passes along the transmission wire through the first electrical choke in a first direction, and subsequently the communication signal passes along the conductor through the first electrical choke in a second direction opposite to the first direction thereby cancelling attenuation of the communication signal by the first electrical choke.

2. The system as recited in claim 1 , wherein the first electrical choke is a cylindrical tube through which the conductor and the transmission wire pass.

3. The system as recited in claim 1 , wherein the first electrical choke comprises a body of a magnetically permeable material.

4. The system as recited in claim 1 , wherein the first electrical choke comprises a body of a ferromagnetic material.

5. The system as recited in claim 1 , wherein the first component comprises a battery.

6. The system as recited in claim 5 , further comprising a truck-side electrical choke arranged such that the power line extends therethrough and on an opposing side of a battery connector than the first electrical choke.

7. The system as recited in claim 6 , wherein the truck-side electrical choke is arranged at a predetermined distance from the battery connector.

8. The system as recited in claim 7 , wherein the predetermined distance is minimized to prevent communication signal loss in the power line.

9. The system as recited in claim 6 , further comprising a second communication circuit operatively connected for at least one of sending and receiving the message signals that travel through the power line.

10. The system as recited in claim 9 , wherein when the second communication circuit transmits a communication signal, the communication signal passes along a second transmission wire through the truck-side electrical choke in the first direction, and subsequently the communication signal passes along the power line through the truck-side electrical choke in the second direction opposite to the first direction thereby cancelling attenuation of the communication signal by the truck-side electrical choke.

11. The system as recited in claim 1 , further comprising a plurality of additional electrical chokes adjacent other components of the industrial vehicle and through which the power line passes.

12. A system for transmitting data between components of an industrial vehicle that are powered by electricity received through a power line, said system comprising:

a first electrical choke configured to attenuate signals and comprising a cylindrical tube of magnetically permeable material and through which a conductor passes, wherein the conductor connects a first component to the power line; and

a first communication circuit for at least one of sending and receiving message signals and having a transmission wire for carrying the message signals, wherein the transmission wire passes through the cylindrical tube and is electrically attached to the conductor at a point between the first electrical choke and the first component,

wherein when the first communication circuit transmits a communication signal, the communication signal passes along the transmission wire through the first electrical choke in a first direction, and subsequently the communication signal passes along the conductor through the first electrical choke in a second direction opposite to the first direction thereby cancelling attenuation of the communication signal by the first electrical choke.

13. The system as recited in claim 12 , wherein the magnetically permeable material is a ferromagnetic material.

14. The system as recited in claim 12 , wherein the first component comprises a battery.

15. The system as recited in claim 14 , further comprising a truck-side electrical choke arranged such that the power line extends therethrough and on an opposing side of a battery connector than the first electrical choke.

16. The system as recited in claim 15 , wherein the truck-side wire bead is arranged at a predetermined distance from the battery connector.

17. The system as recited in claim 16 , wherein the predetermined distance is minimized to prevent communication signal loss in the power line.

18. The system as recited in claim 15 , further comprising a second communication circuit operatively connected for at least one of sending and receiving the message signals that travel through the power line.

19. The system as recited in claim 18 , wherein when the second communication circuit transmits a communication signal, the communication signal passes along a second transmission wire through the truck-side electrical choke in the first direction, and subsequently the communication signal passes along the power line through the truck-side electrical choke in the second direction opposite to the first direction thereby cancelling attenuation of the communication signal by the truck-side electrical choke.

20. The system as recited in claim 12 , further comprising a plurality of additional electrical chokes adjacent other components of the industrial vehicle and through which the power line passes.
