Battery disconnecting case forming assembly for motor vehicle, has electronic circuit forming module including operational amplifier and acceptation unit provided such that common mode voltage of value is accepted by differential amplifier

摘要

The assembly has a battery disconnecting case (1) including a measuring shunt (4) connected between a lug (7) and additional elements e.g. fuse (2) and counterclockwise circular polarization cam switch (3), where the shunt is in the form of a parallelepiped bar. An electronic circuit forming module has an operational amplifier with inputs that are connected to terminals of the shunt, and an acceptation unit that is provided such that a common mode voltage of a value corresponding to a positive terminal potential of a battery is accepted by a differential amplifier.
