Re: Solar Charging Port

If we aren't concerned with practicality, I can think of two ways that it would work. Neither would be real efficient, but they'd work. You could get a DC charger and wire it into the solar panels and/ battery pack. If not that, use the inverter technique, but use a voltmeter and only allow it to discharge the batteries when they are fully charged. That should allow the AC charger to behave normally (I would think).

I will be conducting an EV design/build training seminar for some high school
instructors and one of the objectives of their program is to build a solar
charging carport.  I know that this is not always the most practical thing
to construct, but this is for educational purposes.  I would like to get
some advice from anyone who might be able to point me in the direction of
some ideas.  I am trying to propose the simplest solution possible; it
doesn't need to be as practical as educational (if it takes a few days to
charge the car, that is OK).  I am most interested in charging techniques,
namely how to deal with the fact that the charger will probably not make a
complete charge in a single pass, and how to best deal with this scenario.
I am assuming that the way to go is for the carport to charge some flooded
cells, which then run thru an inverter, to a 110v charger... but if the
charger only runs a few hours a day, how will that effect a "smart
charging"
cycle.  I am also considering wind power, so a combined solar/wind scenario
might be interesting.
