Device to detect charging condition of a storage battery
First Claim
1. A device to detect charging condition of storage batteries comprising in combination:
- a voltage sensing network;
a first logic inverting network with its input gate coupled to said voltage sensing network;
a first plurality of light sources coupled to the output gate of said first logic inverting network;
a second logic inverting network with its input gate coupled to the output gate of said first logic inverting network;
a second plurality of light sources coupled to the output gate of said second logic inverting network;
a printed circuit board to contain the electronic components; and
a face-plate with inscriptions that allows the light of said light sources to be projected outwardly.

Abstract
This relates to a device consisting of a first plurality of light sources that light only when the voltage of a storage battery in a storage battery-generator system is below a predetermined voltage value, which is between the nominal voltage value of the storage battery and the charging voltage value of the storage battery-generator system, indicating that the battery is not receiving charge. A second plurality of light sources that light only when the voltage of a storage battery in a storage battery-generator system is above a predetermined voltage value, which is between the nominal voltage value of the storage battery and the charging voltage value of the storage battery-generator system, indicating that the battery is receiving charge.
