Solar powered lead acid battery rejuvenator and trickle charger

Patent ·
OSTI ID:5332740

This patent describes a solar powered combination rejuvenator and trickle charger for lead acid batteries. It comprises a multi-solar cell power source circuit: a DC to AC inverter multi-vibrator circuit connected to the multi-solar cell power source; a transformer with a primary coil a part of the DC to AC inverter multi-vibrator circuit, and having a secondary coil; a four diode rectifier bridge circuit having a first set of opposite terminals connected to the secondary coil, and a second set of opposite terminals; first connection means for connecting a first one of the terminals of the second set of bridge opposite terminals to a first terminal of a lead acid battery and second connection means for connecting the second of the terminals of the second set of bridge opposite terminals to the second terminal of the lead acid battery; one of the first and second connection means includes connection of a terminal of the second set of bridge opposite terminals to the collector of a transistor and through a voltage bias resistor to the transistor base; connection of the transistor emitter through resistive means to a battery terminal connector; and connection of the transistor base through diode means to the battery terminal connector.
