This is my second version of a Solar Powered Battery-Car.
This version incorporates two sets of charging capabilities, first; is the MC1A PCB Smart Charger, the second is the New Powerfilm Solar Cell that is rated at 15.4V nominal 17.4V - 18.3V at full sun with a 100 milliamp nominal current draw and 150 milliamp in full sun. I will be incorporating additional solar car panels that can be wired in parallel to gain additional amp hours. Powerfilm makes another version of their OEM products that we can get in 300 milliamp charge current. But, this version was designed with two 14.4V 2500mah Nimh Battery-Packs, MC1A 14C PCB Smart Charger, digital volt meter and solar cell voltage regulator that will indicate when the battery pack is fully charged. With this design you can charge both batteries from either the Solar Cell or the MC1A Smart Charger. When the first battery is depleted switch to the secondary battery and charge the first with the solar cell. With additional solar cars (just the solar panel only) we can get about 600 milliamp of charging current to the battery-packs. I’ll have this on display at the 2012 NGRC.
