The following schematic shows the design of a Simple Power Charger Circuit using a Single-Transistor. It starts charging when the battery voltage drops beyond a preset value and stops upon attaining preset voltage. The variable supply is fixed at 13.3 V dc (the voltage of a fully charged battery) and linked to the battery point of the circuit.
