Abstract

A vehicle battery monitoring assembly includes a terminal connectable to a battery post, a shunt formed of a first metallic material, and a cable formed of a different second metallic material. The shunt is connected at one end to the terminal. The assembly further includes a sheet formed of the second metallic material. The sheet is attached on a portion of another end of the shunt. The cable is connected at one end to the sheet.

Claims

1. A vehicle battery monitoring assembly comprising:

a terminal connectable to a battery post;

a shunt formed of a first metallic material, the shunt connected at one end to the terminal;

a cable formed of a different second metallic material; and

a sheet formed of the second metallic material, the sheet attached on a portion of another end of the shunt;

wherein the cable is connected at one end to the sheet.

2. The assembly of claim 1 wherein:

the second metallic material is aluminum.

3. The assembly of claim 2 wherein:

the first metallic material includes copper.

4. The assembly of claim 1 wherein:

the sheet is stamped on the portion of the other end of the shunt to be attached on the portion of the other end of the shunt.

5. The assembly of claim 1 wherein:

the sheet is cladded on the portion of the other end of the shunt to be attached on the portion of the other end of the shunt.

6. The assembly of claim 1 wherein:

the end of the cable is welded to the sheet to be connected to the sheet.

7. The assembly of claim 1 wherein:

the end of the cable is soldered to the sheet to be connected to the sheet.

8. A vehicle energy storage device monitoring assembly comprising:

a terminal connectable to an energy storage device;

a shunt formed of a first metallic material, the shunt connected at one end to the terminal;

a cable formed of a different second metallic material; and

a sheet formed of the second metallic material, the sheet attached on a portion of another end of the shunt;

wherein the cable is connected at one end to the sheet.

9. A monitoring assembly comprising:

a terminal connectable to one of a current sourcing device and a current draining device;

a shunt formed of a first metallic material, the shunt connected at one end to the terminal;

a cable formed of a different second metallic material; and

a sheet formed of the second metallic material, the sheet attached on a portion of another end of the shunt;

wherein the cable is connected at one end to the sheet.
