Definitely not ideal. Not only does the timer fail to accurately predict end of charge (finishing early), it fails by different amounts depending on the beginning SOC.
True, but you can get close.

I will take simplicity over complexity any day. By avoiding a TMS, Nissan's design is simpler, more reliable and doesn't have the thermal run away issues. No Nissan LEAF fires yet like Tesla.

If the new battery is what they say, it is a home run for Nissan. The old battery was suitable for all climates, but desert ones. To have a chemistry that works across all climates, we will all be winners.
they are saying the exact same thing about this "new" hot battery as they were about the original. I was told, emphatically when I bought the 2011 that the testing facility was in Arizona, that Nissan had plowed $5 billion into this technology and made it rock solid, even in the most extreme heat on earth. turns out the original battery can't even take relatively moderately high ambient temps, the further south you go, the faster the battery dies. I won't buy that there is a significant improvement until it starts bearing out in real world user feedback this time around, and I'm not terribly interested in being one of the guinea pigs this time either. once you've been lied to once, you don't readily believe the same thing the second time, I want proof.

Sure the old battery is suitable for moderate climates... if you are content with a life of just over 5 years/60,000 miles.

I'm not sure if this will work on the 2014, but it's worth a shot...

Also more efficient, no vampire load, less Brodering.

Not to mention that end-time-only charging finishes even earlier if a preheat timer is set. Still, setting an end-time for later than my planned departure would work adequately for me, it is just a rather awkward workaround to allow regen when going downhill, when a full charge isn't required.

Exactly. Fool me once, shame on Nissan. Fool me twice, shame on me.

"The old battery was suitable for all climates, but desert ones"? I would switch that around: the current battery is fine for the coastal Pacific Northwest, Norway, and much of Canada. And has unacceptably rapid capacity degradation almost everywhere else.

Home run would be a recall to install the new battery in ALL LEAFs so they will operate as we expected.

2 bar lost at 35,339 miles, 25 months.
