Collecting data:Off-the-wall power for turtle to 100% charge

Mon Nov 21, 2011 9:12 am

I want to start collecting data on the battery capacity of the various Leaf's represented here. Since not everyone has an SOC meter but many of us (all will a little effort) have a means to record the total power used for a full charge. Parital data is welcome (Ex: VLBW to 100%) but please make a note. I'll start with the two datapoints I know of today. Would be very interesting to see the range we have out there.

TickTock: 21.7 kWh Dead to 100 from the wall (20.04 kWh actually entering the battery)
vegastar: 25.5 kWh Turtle to 100 from the wall

Three dead to 100% from the wall for me (data from TED):

26.8 KWh (about a month after I got it)
26.6 kWh
26.1 KWh (most recently)
Leaf SL 2011 to 2016, Volt Premier 2016 to 2019, and now:
2019 Model 3; LR, RWD, FSD, 19" Sport Wheels, silver/black; built 3/17/19, delivered 3/29/19.

If you've had the NTB11-041 update, please also post your Carwings daily "energy used" reports, if they coincide with your
drive from 100% to VLB/turtle/dead.

That appears to me to be the most accurate way to estimate my battery capacity, without an available SOC or wall meter.

Tom - I think you have a Blink SVSE, correct? How closely do the Blink KWh numbers correlate to those of your TED unit? The Blink is my only means of (semi-) accurately measuring actual KWh used to charge, so I'm curious as to how accurate it is...
Ocean Blue SL-e
Per LEAF Spy as of 06/26/18: 11 bars, 222 GIDs, 53.4 AHr on new (04/30/15) Lizard battery (1st bar lost 12/22/17)
Orig. battery lost 4th bar at 177 GIDs, 43.19 AHr, 44.74 Hx, 65% SOH after 45 months

Yep, I have a Blink. The numbers from the Blink (as of the version 1.7 firmware) were within about 2 percent of the TED.

I download the data straight from SDG&E's meter, and find the Blink to be understating the consumed power (during charge) by about 1.5%

ECOtality removed the one "dashboard" tile that was most useful from their web site dashboard -- it had the Blink-reported power out to the milliwatt (literally). Since then, I've stopped using the Blink reporting and just ask the meter how much power was consumed. After all, this is what my bill will reflect.

I've run the car down to turtle, then parked it with the heater on, then left it on with the fans running for hours. The lowest SOC reading I could get was "3". :)

You need more information for these numbers to be meaningful:
  • Voltage and amperage limit. (The longer it takes to charge, the lower the charging efficiency.)
  • Estimated battery temperature. (Cold batteries can't hold as much energy.)

I probably won't be playing, since for me "a little effort" would mean investing in an electric meter and wiring it into the 240v circuit I use for my EVSE upgrade. No, a TED won't work for me; I did look into that.

As TickTock said I got 25.5kW.h from turtle to full. It was charged with the European 230V 16A EVSE included with the car. When it was charged my garage was about 22ºC (72ºF) and the dash displayed 6 temperature bars when empty and when full.

OK summarizing so far:
  • TickTock:21.7 kWh Dead to 100 from the wall (EKM-25IDS meter, 20.04 kWh actually entering the battery)
    vegastar: 25.5 kWh Turtle to 100 from the wall (72F, 6 temp bars)
    TomT: 26.8 kWh Turtle to 100 from the wall (TED, new, 26.1 recently)
Anyone else have data to add? Maybe also mention the type of meter used (Blink, Ted, EKM, Kill-a-watt, or ?) since there seems to be some question on the accuracy of some.

My most recent number is 24.34 kWh from the wall using a Coulomb L2 EVSE. The car was in turtle with 5 gids left before I started charging. I'm seeing between 2% to 5% battery capacity reduction, presumably due to the cold temps (the Leaf is parked outside overnight).
