I just did a full range test in my new 2013 SL and achieved 98.3 miles at an average economy of 4.5 mi/kWh.
If we believe that the 4.5 mi/kWh on the dash is accurate, that reflects available energy in the pack of 21.84 kWh. I'll report on the energy required to recharge to 100% according to my TED monitor in the morning.
I drove most of the day in Drive, with B mode active (increased regen braking). My driving route for the day started with a couple of 5 mile freeway trips in varying speed traffic, with a max speed of about 60 mph. In between the freeway stints, I drove a few miles that included hills at moderate speeds. The rest of the day's driving was conservative suburban driving with some undulating hill sections.
I drove about 80 miles in the above manner, averaging 4.4 mi/kWh on the dash and then I decided to turn the day's drive into a range test. I had the original Gidmeter on.
LBW occurred as expected at 49 Gid, and VLBW at 25 Gid.
I decided to drive it down to about 10 Gid to avoid torturing the poor pack to Turtle. The Gid reading declined steadily to 10 and I stopped the car with the economy display still showing 4.4 mi/kWh and the odometer was at 90.4 miles. I figured that at 10 Gids, I might have one or two miles left before Turtle at 5 Gids. I took readings from the Gidmeter and the LEAF Battery App. I was surprised to notice that with the Gidmeter reading 10 Gids, the SOC% was 9.3%. The LB App also showed 9.3 %SOC, with a much different simulated Gid reading of 26 'Gids. (I realize that simulated Gids are different from true Gids and that the difference is greatest at low SOC, but this was ridiculous). The App said that I still had about 2.1 kWh in the pack and more than 3 miles left to drive at 4.0 mi/kWh. So I decided that with 9.3% SOC remaining, I really should drive down to Turtle to see what happened to the readings. So I turned the car back on and started driving in circles at about 35 mph, watching the Gid reading on the Gidmeter and waiting for Turtle to happen in a couple of miles.
Here's where things got very, very odd indeed.
I drove the car almost 8 more miles between 10 Gids and 5 Gids, ending at 98.3 miles total!!!! I've never seen or heard of this before. It was almost as if the car had a reserve to extend the range below 10 Gid.
The Gid count dropped slowly from 10 to 9 and then lower, but it stopped dropping at 7 Gids and just remained at that reading while I drove about three miles. The Gidmeter SOC% continued to slowly drop. Eventually, the Gid reading dropped to 6 Gid and remained there for more than a mile before dropping to 5 Gid, and finally Turtle appeared. I managed to get into my driveway, but couldn't make it up the short incline into the garage before the car went into Neutral. As I mentioned, the odometer now read 98.3 miles, the energy display was at 4.5 mi/kWh, the Gid display was 4, simulated 'Gids was at 3, and the SOC% was now 1.1% on the Gidmeter and the LB App. Voltage on the Gidmeter was 294 Volts.
I realize that I was hypermiling to an extent, driving at 30 to 35 mph and stopping at a couple of stop signs as I circled near my house, using up that 6 Gid. But there is no way in hell that 6 Gids would provide 7.9 miles of driving! I would expect a maximum of 2 miles, maybe 3 miles at the extreme.
I wonder if this is typical of a 2013 pack, some anomaly of my own quite new pack with only 336 miles on it, or what. I hate to torture my pack, but it would be interesting to see if a similar full range test would produce similar weird results below 10 Gids. EDIT: The LB App showed AH of 63.53 and CAP% of 95.89 at Turtle.
