Abstract

Abstract An electric battery is described comprising a container into which the electric elements are arranged, and on the upper lid of which a hermetically closed housing is located. The housing contains a plurality of interconnected electronic components, forming a voltage comparator which compares a fixed and stable voltage produced from the battery with another voltage proportional to that of the battery, signalling by means of a red light the condition of a low charge or by means of a green light the good condition of the charge, the unit of the circuit being supplied from the terminals of the battery through a push button actuatable for checking purposes.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 111 words
An electric battery comprising a box or container into which the electric elements are arranged, characterized in that the box or container presents, preferably in the upper lid, a hermetically closed housing into which a plurality of interconnected electronic components are placed, forming a voltage comparator which compares a fixed and stable voltage, produced from the battery,with another proportional to that of the battery, signalling by means of a red light the condition of a low charge or by means of a green light the good condition of the charge, the unit of the circuit being supplied from the terminals of the battery through a push button actuatable for checking purposes.
Claim 2
Dependent Claim 111 words
An electric battery comprising a box or container into which the electric elements are arranged, characterized in that the box or container presents, preferably in the upper lid, a hermetically closed housing into which a plurality of interconnected electronic components are placed, forming a voltage comparator which compares a fixed and stable voltage, produced from the battery,with another proportional to that of the battery, signalling by means of a red light the condition of a low charge or by means of a green light the good condition of the charge, the unit of the circuit being supplied from the terminals of the battery through a push button actuatable for checking purposes.
Claim 3
Dependent Claim 114 words
A battery as claime3 in claim 1, characterized in that the circuit contained in the hermetical housing comprises a resistive voltage divider with its central point preferably adjustable, applied to one of the entries of an operational amplifier, to the other entry of which is coupled the stable voltage produced by a Zener diode in series with a silicon diode and supplied by a resistor, the exit of the amplifier being connected to two luminescent diodes in parallel and with inverted polarity at the joining point of two resistors starting from the positive and negative poles of the battery, all supplied by the terminals of the battery to be checked, through a push-button switch.
