Abstract

A solar panel (4) of a battery charger supplies charging current alternately to tow battery-charging stations (11, 14) within the charger-casing (1), during a recurrent operating cycle in which one battery is charged while the open-circuit voltage of the other is monitored during successive periods of the cycle controlled by a microprocessor (25) of a circuit-panel. Charging current is supplied to the batteries via respective transistors (27, 28), only one of which is ON at any time and is pulsed OFF and ON for regulating the averge rate of charging if the output of the solar panel (4) exceeds an optimum magnitude, or for trickle charging the relevant battery if its monitored open-circuit voltage indicates it to be fully charged. Flashing LED indicators (20, 21) show charge conditions and charge-rate of the respective batteries, and guides optimisation of orientation of the casing for fastest charge. Charging stations (11) for two AA batteries are transverse to the stations (14) for two AAA batteries so only one batteries so only one battery-type can be charged at a time.
