Abstract: A starter system for an internal combustion engine in a vehicle includes a starter (12), a voltage source (14) for supplying the starter (12) with electrical energy in a start operating state and a down converter (22). The down converter (22) provides a start operating voltage for the starter (12) in the start operating state by down-converting a supply voltage provided by the voltage source (14).

Abstract: A current-measuring unit, especially for measuring a battery current in a vehicle, includes a printed circuit board (12) and a first bus bar (16) leading to and fixed at the printed circuit board that provides at least one first shunt contact surface (30). A second bus bar (18) leading to and fixed at the printed circuit board provides at least one second shunt contact surface (42). A first measuring strip conductor (44) is associated with the first bus bar at the printed circuit board. A second measuring strip conductor (46) is associated with the second bus bar at the printed circuit board. A shunt resistor (48) has a first contact area (50) connected by soldering to the first bus bar and to the first measuring strip conductor and has a second contact area (52) connected by soldering to the second bus bar and to the second measuring strip conductor.
