While admirable, your strategy doesn't fit the known facts. A charge rate of C/2 (about 12 kw) may in fact be optimal for battery longevity. Both L1 (C/21) and L2 (C/7) are considered slow charges. No difference is expected between them. For supporting data and a fuller explanation, see the end of this section of the Wiki:

I just had my first annual battery check-up on my 2012 Nissan Leaf. I got top marks - 5 stars - across the board! I received these marks because 90% of my battery fill-up happens in my garage at the basic level 1 charge at 110V. I haven't been able to afford the level 2 charging station yet, but still hope to get it soon, saving up for that $1,000 expense.
Bottom line, I knew the 440V charge was detrimental to the batteries, but realizing that the basic charging is best for the car, I will continue to use this method whenever feasible even after getting the level 2 charger.
