Hi I have not. I don't charge it every day back to 100%. I may go 3-4 days before charging back to 100%. The new Leaf does not offer the 80% option, like the previous gens did, so I would have to play with timer settings and that is an issue since I am not always back home at the same time everyday.
I spoke with a Nissan engineer in the USA about this a few months ago and was told, just drive the car like you would normally. Plug it in every night at Level 1 or 2 if you want - no issues. So, that is my take on it. Plus with Nissan's 8-Year warranty, I can live with a 30% loss within that time period if it happens.
This may be a naive approach but I feel for the vast majority of consumers purchasing an EV for the first time, especially a Leaf, this is the way they will drive/charge it. It's the minority that are all hung up on stats, numbers, etc. and analyzing Leaf Spy graphs all the time. I have LSPro so I can get a more accurate Temp and SoC readings, as the current Nissan dash display does not provide enough detail of info. Plus the GOM has a safety buffer of about 10% programmed so that if/when I get down to low SoC, I'll have a clearer picture with LSPro to tell me whats left in the "tank" when I have the dash-dash-dash displaying.
Thanks very much for the link and I'll read that info for sure.
