Abstract

A device for making current measurements used in determining the charging status of a vehicle storage battery, comprising a ground conductor connected between one pole of the storage battery and the ground contact. The pole is connected via electrical conductors to a sensor having a source of electric power for providing at least one electric current to the ground connector. Values which are deducted from the current flowing through the ground conductor are provided to a microprocessor to determine the charging status of the battery.
