Battery current measuring device for motor vehicle, has shunt connected to connecting terminals, and electronic component with lugs connected to terminals by conducting units, where unit has thermoelectric properties similar to shunt

摘要

The device (10) has a shunt (14) with two ends connected to the connecting terminals (12A, 12B). A printed circuit has an electronic component (24) with electrical connecting lugs (26A, 26B). The lugs are connected to the terminals by conducting units (28A, 28B) which are connected to the terminals by upper and lower tracks (PS1, PS2, PI1, PI2) and orifices (20A, 20B). The unit has thermoelectric properties similar to the shunt, where the shunt and the unit are made of Manganin(RTM: copper, nickel and manganese alloy) and Zeranin(RTM: copper, germanium and manganese alloy).
