The circuit below feeds a
controlled current and voltage to a 3.6v lithium ion battery. The current is limited
to 300ma and the voltage is limited to 4.2 volts. The circuit uses a LTC1734 IC from
Linear Technology. No diode is needed between the circuit and a 6 volt solar panel.
Some very nice 6 volt solar panels are available from
http://www.plastecs.com Their SP6-200-12 cranks out about 1 watt while the
SP6-300-12 can produce about 2 watts. Assuming a 6 hour sunlit day, the 2 watt panel
will pump about 1.8 amp-hours into a battery. |
