Automotive Battery Charger Circuit Diagram With Working

A very simple battery charger circuit is described in this article, which uses just a single transistor for the voltage detection as well as for automatically disconnecting the battery from the supply when it gets fully charged. Circuit Description As shown in the diagram we can see a straightforward configuration where a single transistor is connected in it’s standard operating mode. The circuit functioning may be understood with the help of the following points: Considering the battery to be charged is a 12 volt battery, we know that it is advised to charge the battery until it reaches between 13.5 and 14 volts. The transistor base voltage is adjusted using the preset P1, such that the transistor just conducts and operates the relay at around 14 volts. This adjustment becomes the high voltage trip point of the circuit and is used to switch OFF the charging voltage to the battery when it gets fully charged or its voltage reaches around 14 volts. The low...
