Last night I ran my LEAF down until it wouldn't move. I was driving 70mph on the highway. I got my first low-battery warning at 8 miles remaining on the GoM (Guess-O-Meter), at which time the yellow triangle and the "gas pump with cord" light came on. There was a verbal warning and the navi asked me if I wanted to find a charge station. I turned around and headed home at the 6 mile GoM mark.
Then still on the highway going 65mph, at 3 miles, the verbal/navi warning repeated, maybe it was my imagination, but she seemed worried when she spoke. =)
A few more miles later, I then descended into no-mans land with the --- flashing on the GoM and **** shown on the miles remaining energy screen. I had the heat on high (~3kW) and kept driving aggressively around my area, I clocked about 4 miles, then I noticed some reduction in acceleration. Shortly thereafter, the dreaded turtle-of-death appeared and the car really did stop accelerating. I pulled into my garage and continued to move back and forth with CC still on high heat, and finally the car performed an auto Ig-off. (Battery Contactor Opened) It went into the same mode as you would with 2 power switch presses w/o the brake. The main indicator was the red "battery" light along with the clunk of the contactor. CC wouldn't show any power draw, although fan was still running, and car would only shift into neutral when trying to drive.
All-in-all, the GoM did a good job, giving me about 5 miles of aggressive driving after ---, which probably would have been up to 10 if killing the CC, being careful and creeping along.
My car has the newest firmware.
