Re: Leaf Spy and Leaf Spy Pro (previously Leaf Battery App)

Thanks for update Turbo3! I noticed that previously the ambient temperature was displayed in F on the 4th page but this doesnt show in C. Could you please get that added to the app?

Also would like ability to remove GID's bar from page4 or at least ability to change colour of those bars as its the screen I use the most.

For a future feature, would it be possible to record journey stats i.e. when a start button is pressed, miles are totalled along with kwh used and on pressing stop line is saved to a separate text file (journeys.csv) containing the miles covered and watts used, maybe also min and max batt temperature?

Many thanks

Jim,

I am now a happy pro owner and the app works fine. As you probably know, the 2013 Leafs made May or later report some values differently than prior Leafs. Specifically, capacity when new is usually about 61Ahr and miles reserved below vlbw is greater. I would much rather know distance to turtle than distance to lbw or vlbw.

I understand that distance to turtle is difficult to estimate and that the current distance to reserve function helps some. As a temporary help if you could add bubbles in the settings for 0 and 1% SOC reserved it would help until a way to calculate distance to turtle can be worked out.

Also, since many of your new users will more and more be 2013 owners,
It would help if initial setup included a notice notifying a new user that the 2013s have lower new capacities. Currently there are appearing more 2013 owners very worried when they install leafspy on their new car and get a value of 90% of "new"

At the same time I think you should rename health as simply "H" or H-factor. It really isn't the health of the battery. I actually think this value shouldn't be available to most users at all, since we really don't know what it represents.
Blessings,
Holland

2 LEAFS, bought 1 week apart. 2013 S for me, 2013 SV is wife's. Both manufactured May 2013, both battery capacity about 60.5 AHr. Both with normal range. No degradation after 2 years and 19,000 miles.

The reason the app does not show ambient in C units is I am not sure of the ambient message format for Leafs that default to C units.

For F the app uses the following conversion to go from raw message data to degrees F: Ambient=BB(4)-52

I will need an ELM trace from a Leaf that displays the ambient in C to learn the conversion formula. I will also need to know what the dash ambient was at the time the ELM trace was taken. It should be taken after the Leaf has been sitting at the same temperature for an hour to be sure the raw and dash are the same since the dash takes a long time to respond to ambient changes.

Version 0.28.12 will allow percent value selections of 0 and 1 for SOC reserved.

I will also switch to displaying the real Battery Health value from CAN message 0x5B3. However, for now Health will only be read once each time the app is started as it requires special code. So if Health changes while you drive you will not see the change until you exit and restart the app.

I see newer cars and the once that has P3227 update report 60,5ah from the app. But GIDS are only 255, not 281 as before. Is then about 255 GIDS normal?
My car is 2012 model With P3227 update AHr went from 66.4 to 60.5 in only one month after update.

I think it is because P3227 update gives you more accurate readings, while pre-update leafs in cold climates reports high AHr. Mine Leaf is also not yet updated.
What mileage you have?

Just finishing up the testing of the next version 0.28.12. Here are screenshots of the first screen with the new SOH (State of Health) replacing the older value that was called Hlth (Health) which is now renamed to Hx since we are not sure what it really means. Also cleaned up the QC and L1/L2 layout based on Gary Giddings suggestions.

Looks good. Look forward to see SOH on my battery

The previous tolerance was plus or minus 10 percent. Post P3227 it is plus 0 and minus 4 percent...
