That is strange, because 13V is too low to fully charge a lead-acid battery, especially when new, I have seen AGMs after being off-charge for a day, they still read 13.25V When I put lead-acid on a constant voltage (current limited) supply to recharge then I typically set it to at least 13.6V if occasionally the supply might be powered off or the battery disconnected, so it needs to recharge relatively fast, else I might set it to float at 13.5V and you will then see the float charge current go to a very low trickle. I wonder what the reason is that Nissan lowered the voltage to 13.0V
Anyway, a solar charger is by definition a current limited device and low current at that, so it will typically drop to the DC/DC output voltage and only in case the vehicle is turned off a long time while the panel is constantly charging, might it be able to bring the battery voltage up to 13.5V or whatever voltage you regulate the panel output to.

Just keep in mind that the LEAF only floats the battery at 13.0V when the car is on most of the time. Not sure what will happen if you try to push the battery above that while the DC-DC inverter is on. It could be OK, but just beware. -Dave _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA) -------------- next part -------------- A non-text attachment was scrubbed...
