Will check some regen road data one of these days, certainly does seem strange?

The graph is old cached data as I only used caniOn to check the battery balance and check to see if the fps died with hands free picking up incoming calls. I included that graph only for the data on the left side showing the total Kms and SOC for reference. So ya, ignore the graph.... Confusing and should not have added it.

BTW, the ECOmeter pegs anti clockwise on the 2012 models when the brake is fearthered under the right conditions so will be interested to see the regen data on it. I think Kurt has looked at all this? Be interesting to know how it is calculated?

Regen can show for example + 200% as you might have reset the trip meter and then driven out of your driveway and rolled down a 100m hill. The total trip to that time is short but a large portion was regen. It's the same with the lt 100km gauge on most ice cars . If you reset the l/100km meter and then drive out the service station flat out then full throttle up a little hill. Then stop at the lights the lt/100 shows something silly like 65/lt 100km but as you drive on more it slowly comes down and down represent a more realistic avarage.

Regarding incoming calls. I think acmotor is referring to taking calls on the same device that is running canion. (His android phone) So testing taking a blue tooth call on hands free while running canion on a android tablet isn't the same thing.

I said before that flicking through screens while it's logging live is where I see issues with freezing . Just keeping it on one screen. Usually the trip view screen while logging is reasonably stable. Once I have finished the trip then it's fine to scroll through all the screens.

Thanks Kurt, I guess that makes sense.... will play with it sometime.

Hands-free with caniOn logging data worked fine with an S3 as well when I first started looking at the app a month or so ago. But never repeatedly tested it. Only used it a few times from memory so can't comment on longer term dropout issues?

http://myimiev.com/forum/viewtopic.php? ... &start=110

shall try this tip out.

"
about canion's stability/freezing.

Bonsoir
Martin made a nice mod in rel 111:
it is possible to make an easier life for canion...
this mod was made for slower android devices.

you just create or delete from 1 to 4 files in the folder BT_CAN

nomaps.txt
nocockpit.txt
nogps.txt
noaccpedal.txt

the content of these files can be whatever you like,
when canion starts, it checks the presence of these files and do less work accordingly.

the names are self-explanatory, these options are independant.

thank you for testing and reporting your results...

Xavier

Interest comments; love that US i-MiEV forum.

One difference that I am doing is I use the button on the stylus on the Note 8 to grab a screenshot directly from whichever of the 12 screens I am in. Seems to be happy either in the native screen mode or the graphics only screen display mode that you get by taping the normal screen display screen. I am using the STN1170. Everything is as per the original install.

Wonder if it is to do with processing speed of your device? Any idea of the fps you get when it’s working correctly (as shown in the little yellow window bottom right)??

As Kurt says, they really welcome feedback and it is a tool in development.

Forgot, the other thing I find is it connects every time (I think) if I just leave it in the OBD2 socket all the time. Just turn the EV to READY then start the caniOn app….. But if I have unplugged the STN1170 and plug it back in, I find I may need to remove it again and put it back in and even restart the tablet sometimes.

Good luck
Bruce

generally get 400+ fps

have currently turned off maps
with nomaps.txt dummy file in the BT_CAN folder.

yes I had to discon/recon dongle yesterday, but generally have left the dongle in situ.


half deciding to get one myself, currently on special $US99.95 vs $US199.95 + postage.

did have a look earlier in the year but the price was a bit steep.

<edit> ordered one now, yeah!

400fps sounds fine, I do have feeling that the nexus 7, v2 that I have has some Bluetooth teething issues in general. Powerful tablet but Bluetooth can be a little hit and miss comparing it to say my iPhone.

Dam it I'm missing my imiev already 2200km away. I'm in Adelaide at the moment might checkout the fast charger while I'm going past it tomorrow.

Adelaide-EV stopped in day to use the caniOn app to check the balance status of the pack in her beautiful new i-MiEV.

Here is the result....

Another well balanced 88 cell pack!

BTW caniOn worked 100%?

That's good Bruce. According to canion at least, these imiev packs balance up well.

After wading through the myimiev forum xavier is telling us the current reading is a calibration in his software not an absolute CAN bus value ? I'm thinking there should be two values from the hi low sensors. Are these a % of some full value ? How do others read what is going on here ?

need to do another test, sometime, this time at 80kmh speed limit.
probably will be using around 32kW power?
was running low on power so didn't want to risk it.

Nice to see the Greenmount data!
For those folk in other places, Greenmount 'rise' is the closest we have to a hill in Perth. Image

should also include batt data next time.
Using the nomads.txt dummy file, it works.
xavier may need to add more code to stop the crashes.

Early days still in the life of the app.

Would be super if there was an iPhone app

nexus 7 doesn't charge when the app is running also batt power seems to be used up
So don't try driving for 8 hours in a stretch as your tablet may be flat by then.

one tip with the OBDII dongle / CanIon app.
a) power up the i,
b) then run CanIon app.

else comms seem to be lost, had been getting 0 fps, otherwise.

i've just realised that the eco section goes to about 1pm so it doesn't matter too much that one is doing 70/80kmh

80kmh is probably the limit of going into the power zone.

at a guess probably using 20kW @ 80kmh vs 16kW @ 70kmh

Note after connecting with one imiev need to delete / rename btcan.db file
when connecting to a different imiev
else get blank graphs.

one thing to watch out for when using the CanIon app.
turn off Bluetooth Audio streaming.
This seems to use up bluetooth bandwidth and cause dropouts.

Kurt are you able to confirm this?

I often use Bluetooth Audio streaming to watch video via the nexus 7.
the speakers are surprisingly good.

Not sure about audio streaming. Is this just having another divice receiving audio from the nexus ? As in pairing the nexus with the car stereo and streaming music via blue tooth while cannon is ruining?

I just tried the above and it connects to both. But as soon as you switch to the music player app (pandora) and then back again to canion you loose sink on canion and have to quit and restart it. If you start streaming music first then open canion and stay in the canion app both will run at the same time. How stable the connection is over time is another thing.

It was mentioned earlier about turning off maps and cockpit for more stability. How is this done?

I am getting the feeling canion is resource hungry and if you want reliable clean logs even on a powerful tablet like the nexus 7 you need to dedicate the tablet to the one task or risk stability issues.

I'm more or less just using canion now and then as a health check up. Now that I have some good clean logs of my typical commutes all done on a near new battery. I now have a base line for temps, voltages, balance, voltage drop under load and efficiency. I can compare them to results in the future as the battery gets older. It's more or less just a once a week check up for me now. Though if more features are added to canion this will change.

I ran the car in 40C weather (record breaking for the sunshine coast hinterland) a few days ago with AC on over the full 104km tip. This is about as extreme as things would ever get for my Imiev and it ran perfect. Shame I didn't have my tablet on me at the time to log cell temps. I could hold my hand (just) on the motor afterwards.

I also notice that others have cell block / unit 64 showing high temps in comparison to all the others.

Wold be interesting to know why this is. Perhaps radiant heat from some component in the battery box near the temp probe?
