I went to start my 2015 LEAF SL a few days ago and got the error message "T/M System Malfunction". The car would not start or allow me to put in into gear. I feared that there was something major wrong with the transmission. Thanks to this forum I leaned that this message is often seen, when...

Does anyone know where I can get an "Electric Car" or "100% Electric" Decal for my LEAF? I would prefer a window decal, if I could find one.

Is it possible to add a quick charge port like a ChaDeMo to a 2015 LEAF SV?

Well, it seems to me that you have come full circle, which is a good thing, since I believe that your contention that Ah and GID's can't be compared is dead wrong. Ah X V = Wh, which is proportional to GID's, Or to be more accurate, you would integrate the area under the Ah vs. V curve that...

So, are you saying that there is no data available from a LeafSpy that will effectively act as a "gas gauge" for a LEAF? That is, if your battery has 60% of its new capacity (I believe that would be 39.75 Ah) remaining and you charge it fully, then a LeafSpy will simply continue to tell you...

In discussing with a very EV Savvy friend about how might be estimating battery capacity at any given time, he suggested that one way would be for them to integrate Amps for a given time (thereby getting Ah), looking for the point at which the battery voltage drops a given amount (thereby...

No, actually that's not "obvious" at all. How do you know that half of your data wasn't recorded when the moon was not in the correct phase, and the unknown Nissan Algorithm takes phase of the moon into account in its calculations? Admittedly a very far out example, but you'll get my point...

The Battery Warranty in question reads "Nissan will repair or replace a Leaf's battery within five years or 60,000 miles (whichever comes first), if it loses more than 30 percent of its charge capacity. For Leaf owners, that means the warranty kicks in if the 12-bar battery (Capacity) gauge...

So, based on the mwalsh values (bottom end of 9th bar at 41.77 Ah) you may not actually quite be there yet. At least that's more palatable than being at the bottom of the 9th bar for over a month, and it not dropping off your display.

I understand what you're saying about the definition of SOH. GID Meters have a "Real SOC " feature that is not normalized. So you can calculate the real current capacity of your battery. I believe that I recall from a previous post that 43 Ah should be the bottom end of the 9th Capacity...

Forgive my ignorance, but, if that 66.22 value is SOH (state of health) instead of SOC (state of charge), would that be a significant difference?

It seems to me that there should be no question about "whether Nissan is using the GID". We are supposedly looking at Nissan's own digital charge capacity data here, regardless of whether you call it a GID or a Googleplex. No matter what you call it, the percentage calculation should still...

Well that is good to know, but it still begs the question "did Nissan make the algorithm tougher at my last 6 month LEAF check-up"? We would never know!

It seems to me that figuring out how the Nissan Battery Capacity Bar Algorithm actually works can not be insurmountable, if we consider a large enough body of data from lots of LEAF owners. Fooljoe has stated that two weeks of LEAF charges, all below Nissan's published 66.25% bottom end of the...
