Abstract

A pole terminal is formed as an intermediate piece and has toward the bottom a clamping piece for fastening to a conventional battery pole and toward the top a pole body to which a conventional battery terminal can be fastened. In the pole terminal there are a Hall element and an evaluation electronics so that the current flow through the pole body can be measured.

Claims

1. A pole terminal for a storage battery, which has connections for an indicating or measuring device comprising:

a pole body for connection to a conventional cable connection clamp of a battery cable, the pole body being formed with the configuration of a battery pole; and

a current sensor located within said pole body for detecting current flowing through the battery pole.

2. The pole terminal as set forth in claim 1, wherein

the pole body of the connection terminal has a clamping piece for fastening the pole terminal to a battery pole.

3. The pole terminal as set forth in claim 2, wherein

the pole body and the clamping piece are arranged coaxially with respect to each other.

4. The pole terminal as set forth in claim 3, further comprising

a housing secured to one side of said pole body for support of electronic circuitry;

and wherein

connections for a display or measuring device are provided on said housing.

5. The pole terminal as set forth in claim 3, further comprising

an annular core which has a radial gap and encircles the pole body, there being a holding element including a current sensor located in the gap.

6. The pole terminal as set forth in claim 5, further comprising a flange encircling the pole body;

and wherein

the annular core encircles the flange of the pole body.

7. The pole terminal as set forth in claim 5, further comprising a housing enclosing the annular core.

8. The pole terminal as set forth in claim 7, wherein said housing encloses said flange.

9. The pole terminal as set forth in claim 5, further comprising a housing secured to one side of said pole body, and an evaluation electronics circuit located for processing a Hall voltage of the current sensor, said current sensor comprising a Hall device.
