Aside from the discussion on the merits of charging while driving, I am still curious about the technical feasibility of "Charging while driving".
Specifically, I'm wondering how the Leafs on-board computers would react to getting a charge independent of its own regen? Would it consider this an error/fault condition?
Since the normal built-in charger is locked out during operation, what would happen if an independent charger were used - such as the one detailed at http://www.mynissanleaf.com/viewtopic.php?f=37&t=12323
? I would think you should be able to use an AC source with this method.
I've seen a few videos detail how to add an external battery pack https://www.youtube.com/watch?v=Ztejn3YYbvw
and a few videos show what can go wrong: https://www.youtube.com/watch?v=7vD2VBAYdTg
From what I gather, it seems like yes, you can add charge to the Leaf while driving (independent of regen) but you need to be mindful not to cause pack imbalance beyond a certain limit. Would still like to hear from anyone else with experience on this subject though!
However, as I often have to remind myself, just because you can do something doesn't mean you should do something - in the end it's probably better to go with a Volt or i3 Rex if you desire to charge while driving.
