Abstract

A connector suitable for establishing an electrical connection with any number of batteries. The connector including any number of features for assessing operating characteristics associated with the battery, such as but not limited to current, voltage, and temperature. The connector optionally being of a robust design and configured to ameliorate vibrations and sustain hammer tests.

Claims

1. A battery post connector for use in sensing current flow of a vehicle battery, the connector comprising:

a terminal adapter configured for compressively connecting to a battery post of the vehicle battery and establishing an electrical connection thereto;

a shunt in communication with the terminal adapter and configured for directing current flow between the terminal adapter and a vehicle element;

a printed circuit board (PCB) configured to calculate current flow through the shunt as a function of a voltage drop across a portion of the shunt;

a plate overlaying at least a portion of the PCB and shunt and configured to ameliorate shunt vibrations; and

wherein the plate is an independent element fastened to both of the terminal adapter and shunt.

2. The connector of claim 1 further comprising a network interface for communicating signals between the PCB and a remote network element, the network interface being separate from the electrical connection between the shunt and vehicle element.

3. The connector of claim 1 wherein the plate is not fastened to the PCB.

4. The connector of claim 1 further comprising a resin encapsulating the shunt, plate, PCB, and at portion of the terminal adapter.

5. The connector of claim 1 wherein the PCB includes a temperature sensor for sensing temperature.

6. The connector of claim 1 wherein the terminal adapter includes a recessed ledge for receiving the shunt, the recessed ledge corresponding with a thickness of the shunt such that a top side of the shunt lies flush with a top side of the terminal adapter and a bottom side of the plate when the plate is fastened to the top side of the terminal adapter.

7. The connector of claim 6 wherein the shunt is soldered to the terminal adapter and include a three materials sections.

8. The connector of claim 1 wherein the plate is fastened to a top side of the terminal adapter and the PCB is fastened to a bottom side of the terminal adapter.

9. The connector of claim 8 wherein the PCB is fastened to the bottom side of the terminal adapter such that the PCB is offset from the shunt.

10. The connector of claim 1 further comprising a pair of connecting pins configured for establishing an electrical connection between the shunt and PCB, the electrical connection suitable for use by the PCB in determining the voltage drop.

11. The connector of claim 10 further comprising corresponding apertures in each of the PCB and the shunt for receipt of the connecting pins and establishment of the electrical connection.

12. The connector of claim 10 wherein the connecting pins includes offsets to facilitate offsetting the PCB relative to the shunt.

13. A battery post connector for use in sensing current flow of a vehicle battery, the connector comprising:

a terminal adapter configured for compressively connecting to a battery post of the vehicle battery and establishing an electrical connection thereto;

a shunt in communication with the terminal adapter and configured for directing current flow between the terminal adapter and a vehicle element;

a printed circuit board (PCB) configured to calculate current flow through the shunt as a function of a voltage drop across a portion of the shunt;

a plate overlaying at least a portion of the PCB and shunt, wherein the plate is fastened to the terminal adapter and the shunt;

a pair of connecting pins configured for establishing an electrical connection between the shunt and PCB, the electrical connection suitable for use by the PCB in determining the voltage drop;

a network interface for communicating signals between the PCB and

a remote network element, the network interface being separate from the electrical connection between the shunt and vehicle element; and

a resin encapsulating the shunt, plate, PCB, and at portion of the terminal adapter.

14. The connector of claim 13 wherein the PCB includes a temperature sensor for sensing temperature.

15. A connector for use in sensing current flow of a battery, the connector comprising:

a terminal adapter configured for connecting to the battery and establishing an electrical connection thereto;

a shunt in communication with the terminal adapter and configured for directing current flow between the terminal adapter and another remote element;

a printed circuit board (PCB) in electrical communication with the shunt and configured for determining operating characteristics associated with the battery as a function thereof; and

a plate overlaying at least a portion of the PCB and shunt, the plate being sufficiently thick to protect the PCB against a hammer test;

wherein an entire bottom side of the plate is flat such that the outer edges of the plate rest against and are coplanar with a top side of the terminal adapter and the shunt.

16. The connector of claim 15 wherein the terminal adapter includes a recessed ledge for receiving the shunt, the recessed ledge corresponding with a thickness of the shunt such that a top side of the shunt lies flush with a top side of the terminal adapter and a bottom side of the plate when the plate is fastened to the top side of the terminal adapter.

17. The connector of claim 15 wherein the plate is fastened to a top side of the terminal adapter and the PCB is fastened to a bottom side of the terminal adapter such that the PCB is offset from the shunt by a thickness of a portion of the terminal adapter.

18. The connector of claim 15 further comprising a pair of connecting pins configured for establishing the electrical connection between the shunt and PCB, the electrical connection suitable for use by the PCB in determining a voltage drop associate with current flow through the shunt.

19. The connector of claim 18 further comprising corresponding apertures in each of the PCB and the shunt for receipt of the connecting pins and establishment of the electrical connection, wherein the connecting pins includes offsets to facilitate offsetting the PCB relative to the shunt.
