Abstract:
1. A method of making a measuring device for measuring a current flowing in a cable connected to a battery, the method comprising: forming a measuring shunt from a resistive alloy, the measuring shunt comprising holes defining a measuring portion disposed between a first connection portion and a second connection portion; coupling a conductive core of the cable to the first connection portion by autogenous welding; coupling the second connection portion by autogenous welding to a conductive tab integral with a battery cable terminal, wherein the conductive tab extends perpendicular to an axis of the battery cable terminal and includes a total thickness less than the thickness of the battery cable terminal; and coupling a measuring electronic circuit to the measuring shunt by engaging connection pins of the electronic control circuit into the holes of the measuring shunt, the measuring electronic circuit being coupled to a data transmission cable.
