Battery charging system utilizing optical gas sensor
A battery charging system utilizing a gas pressure transducer which increases in resistance in response to increased gas pressure. The gas pressure transducer comprises an optical transducer. Respective rubber diaphragm chambers, communicating with the cells through glass and plastic tubing, are disposed to form a channel therebetween. A light bulb and a photo-resistor are placed at the respective ends of the channel. Increased gas pressure from the cells forces the centers of the diaphragm closer together to restrict the channel region, and thus decrease the light received by the photo-resistor as a function of gas pressure. In addition, a timing circuit utilizing the transistor for control of an SCR switch is disclosed.
