I just got a 16/32 volt buck/help transformer, 1kva. I'm supposing it may enable my charge to hold up time on excursions by raising the charging voltage a tad. I realize 240 is great, and that is the primary concern I'm attempting to do is to take the 208 volts from certain spots and knock it to 240. In any case, imagine a scenario in which I took the 240 and knock it up to 272. Would that sear the leaf
The car doesn't care if you give it 208V or 240V. It'll draw 6.6kW and charge. It'll draw ~31A@208V and~27A@240V. I don't know what the max input voltage is for the charger, but I don't see any point or advantage to raising it above 240V, nor do I see any advantage to bumping to 240V from 208V.
1kVA is 1000W. You're going to decrease your charge wattage by 5600W with that little transformer.
