Lets say I am using LM317, Actually my main question is conduction through the transistor. When it conducts?
I used think when bettery is in heavy charging state (low voltage across battery), the trasistor does not conduct. When battery gets full charging voltage, the transistor conducts and shorts the ADJ then the charging stops through LM317. Overall circuit operation making me confuse.
But simulation shows the transistor conducts when bettery is in heavy charging state. Probably I made wrong concept.
