drees said:4.0V / cell is a standard 80% charge, not full charge. Not the best for long term storage, but it's what Nissan recommends.
Even at $4000 it's the cheapest we've seen 48 modules sold for yet.
ahagge - not likely that swapping out only a couple modules would do you any good - so far modules in the pack tend to degrade pretty evenly.
Is this really true? I have a 2013 that Leaf Spy shows ONE module that is low upon discharge, and it is this one module that forces the car to turtle every time. With Leaf Spy, on a full charge, I always start at 284 gids (101% gids), 97% SOC, 22 kWh available, and that module is level with all the rest. But at turtle, I'm at 6 GIDS (2% gids) and around 12% SOC, 20 kWh used. This seems to indicate that the one bad module is making me lose about 10% of my potential range. Of course once you get a bad module, it should get progressively worse due to temperature. As the module drains down, the voltage decreases, the internal resistance increases, and the amount of heat generated increases, making this module hotter than the rest of the pack. Thus leading to a greater rate of capacity loss in the future. (or at least I think this is all true).
I would think that in my leaf, replacing that one module would give me a 10% greater range.
I've been posting this a few times, wondering if anyone else has a leaf with a single low module and what effects they see. But I'm starting to wonder if I'm the only one. To my knowledge there are no error codes registered from a single low module, so unless you have LeafSpy or LeafDD, you would never know...except that your leaf just doesn't go as far as it should. And 10% is pretty hard to measure with certainty
Oh and on that storage at 80%. How many of you see brand new Leafs a the dealer charged up to 100%???? Nissan doesn't even follow Nissan's own advice.
