the watering cap (terskelverdi) says 870 Ah.

I would say that this is the normal value, whatever the charge rate you set. I think that the lower value of 450Ah is a kind of "degraded mode" where the ECU goes only after an internal bug requiring a parameter reset (or "load parameters"). It is generally associated with the fault "Parameters of the Control Unit".

I experienced Checkelec stopping yesterday. Had to close Checkelec with Advanced Task Killer to get it to connect again to the PRODIAG unit.

What kind of stopping ? App freeze ? Or PSA connection unrecoverable ? I changed many things in the next version so that there will be fewer disconnections and less app crash. Coming soon...

HI Steens.
I have had some problems with the scale on the current (see picture). As you can see it goes form 0 to 20A. Not sure if it was a temporary problem or if it's fixed now, but when I open it now even with no car connected I see -100 to + 150 A.

First picture from left, I am charging with my homemade semifastcharger.  Second is with only the cars charger. On these two we need to change the heading from "Lading" to "Lader". Third is after the charger is disconnected. Heading "Lading stoppet" is fine. Then on the fourth I am driving. The heading "Lading stoppet" is not so appropriate. Not sure if this is a translation problem (by me) or a program state problem ??

When you start a charge, the app replaces the pages "charge" and "monitoring" by a special page to monitor the charge. It looks like the "monitoring" page but with the following differences :

• The type of charge is indicated
• The time scale is different (1 hour per division)
• The current scale is adapted to the charge (but maybe not to fast chargers )
• The voltage scale is also higher than in driving mode
• The current sign is inverted so it is positive when charging (but I know, current sign is a big topic )
• The sampling is only one point per minute

When you stop the charge, the "charge monitoring" page remains so you can look at the curve. Once you come back to the menu, you will retrieve the normal pages in "monitoring" and "charge".
So what you describe seems ok to me, just go back to the menu and return in "monitoring" page before driving. The only problem is when you charge with a current higher than 20A. I will think about it for a future evolution.

OK, so my observation was due to "user error"
But as you can see I did not see any curve at all, even if the charging + driving lasted for over an hour

- The current scale is adapted to the charge (but maybe not to fast chargers )

My semi-fast-charger is not very fast. I think I can get up to about 50A current including the internal charger.

[Steens]

But as you can see I did not see any curve at all, even if the charging + driving lasted for over an hour

Both graphs were after 1 hour ? Do you mean the app was connected (not in background) during one hour, or you entered in the monitoring page after one hour ? We can see on the second that there is at least two points.

On the first graph, the current is out of scale so it's not surprising that there is no current curve but we should see the voltage curve

[Elmo]

No, the first graph (36A) was when I started charging, the 9A and 0A was some 30+ minutes later when I disconnected the charging and the last (-106A) was while driving som 10 minutes later. As far as I know it was connected all the time.
But rather than pursuing this now, I think I will try it out again then your new version is available.

Hi Elmo! Have you put your extra charge coupling to the fast charge poles in the top of the elbox? Seen from the front, two most left poles? Connected that way I get correct readings and car system also noticed total charge.

Yesterday I had Partner in my workshop and there was glowing fault light and watering light. Lexia was give several warnings and the overcharge was something like 1200h and calculator was saying 1120h. I telecoding current from the net to 13A, after that I put car for charging some one minute and everything was ok; over charge limit was change to 870h.
Before I changed these things I was checking all the four memories and Lexia say's they were ok. Life is so unpredictable....

I also using Diagbox which is newer PSA program. It includes also Lexia and you can choose what you using.

About Checkelec, I found it very useful to see what state the charge is. Car charging outside in the pouring rain and program tell's me in the warm inside of the house voltages and currents. Skool, Steens! Excellent travail!

Best regards

I actually have er Marechal chargingcord that includes the fast-charging connectors - which connects to the poles you are mentioning
Ito get correct radings using Lexia or evLite, so the problem that I menioned must have been with the app og my phone.

I have seen the Diagbox program om my disks, but I never understood that this is actually an alternative to Lexia/Proxia/PP2000 that I have all tried.

Hi Steens,
Here are my observations about your wonderful app. I have lithiumized Saxo, Y1000 version of Sagembox, ECU version is 4.3 (based on my not so reliable memory , 105kkm, 67kkm on lithium).
ODB adapter is Vgate iCar2 from https://tinyurl.com/iCar2 . It connects well and is awaken after asleep by pressing button. Mobile phone is ancient Samsung GT-i9000 loaded vith Android ver. 6.0.1 (serves well as BMS data display).

Current values are OK. Maximum current is 200A, my BMS confirms the same value. Picture represents  maximum acceleration to max. speed for 4 minutes. 
Voltage values are not correct. It seems that they are off by 26%. I will collect more data and give you exact value.

Once the app lost link, sliding it off and restarting reestablished connection.

Interesting fact - since I monitor battery current and this app motor current, I have confirmed what I have noticed for some time - just before full stop, if brakes are pressed (for pedal switch activation),  engine reverts from regen and enters dissipative  braking mode. (not by much, 4A only but you can feel slight jerk). I suspect something similar happens on emergency braking on larger scale.

I think maybe I know the cause of my problem above.
Today I had the logging on during a 27km drive to work with my Saxo. It work fine all the time, so I wanted to take a screenshot. 
BUT, when I took up the phone to do it, the screen flipped (vertical to horisontal) and all the logging was gone

Is that something you can fix Steens ??

Hi Marin,
Thanks for your feedback. I already noticed this problem. It is confirmed by your screenshots : your ECU has an Autodiag version 31 while the most common version is 32 (And the app was developped for v32). In Autodiag v31, there is a different scaling coefficient for voltage. The next Checkelec version will take the Autodiag version into account. I have estimated the coefficient for v31 but I still need a more precise value. Do you have the Lexia software ?

I have seen the Diagbox program om my disks, but I never understood that this is actually an alternative to Lexia/Proxia/PP2000 that I have all tried.

Diagbox is just a PSA user interface working for all PSA vehicles (not only electric ones) and that launches the right program depending on your vehicle selection. So if you select "Saxo", it will launch Lexia and if you select "106", it will launch PP2000.

So far it has been 3 times in Checkelec voltage/current monitoring mode that the graph has stopped (permanently) when using my PRODIAG OBDII unit. I am not sure about all three times but the first time the software simply stopped/closed/disappeared and the last time so far it was only the communication that stopped and Checkelec managed to reconnect. I have BTW had much fewer such incidents with the PRODIAG OBDII unit then with the Vgate (more often with my Vgate).

Additionally I sometimes also experience that the graph seems to go into "pause" with no update/activity on current/voltage values before the graph suddenly jumps quite a bit to the right with just one sample and then continues "as normal".

I am looking forward to the new version

I know, it happened to me recently also ! I definitely need to correct this. However, for the coming version I worked on fault codes reading/clearing and water need clearing (and bug correction). I will then work on data logging for the following version.

By the way, I'm looking for a beta tester to test the water need clearing function. So, if someone plan a maintenance charge with water refill in the very next days, I can provide a beta version. Let me know.

[Niram1969 .]

Yes, I have Lexia. I'll report my findings.

I can do that. I dont think either of mye cars need watherservice right now, but I am happy to clear the conter on one of them without doing the maintenance charge, og actually do the maintenance charge too if you think that is importene.
Ie. I guess it is sufficient too see that the counter goes to 0, but maybe you would like to verify that the wather-light is turned off too ?
