In this case, the cables could be very short.

Look at the pictures named "SnorrePlacing", and immagine the white sheet is the left gloove box's cover. This is the solution I was suggesting you....

@JPB
With all these photos, your unit is becoming a v.i.p. (or... it feels so!)

Delvecchio schrieb: Another good news: two units are ready to be sent to you, and other two will be within the end of this month.
Till now I received in public/private request from this users, in cronological order:

Snorre
Saarlodrie
TwizyCamper

I will defintely buy one in CAN bus version.
Right now I'm unsure whether I will prefer shorter cables or not.
So I will tell you at the end of this month.

Found time to take some consumption measures:

in standby mode (LCD and Gyro off; ESP32 and canBus module sleeping),


during wake up (LCD and Gyro off; ESP32 and canBus module ON)


and in active mode (LCD, Gyro, ESP32 and canBus module all ON).

Hier mal ein kurzes Fazit nach einem ersten Test (bislang nur in der Garage, da das Wetter mir zu schlecht ist.)

Verarbeitung: Top, besser kann man es sich für ein Hobby Projekt nicht vorstellen. Alle Kanten sind abgerundet, keine Spuren von "Beschädigungen" o.Ä.

Instalation: Sehr einfach. Ich habe es erst mal nur lose verdrahtet, da ich es auch in mehreren Fahrzeugen testen wollte.

Funktion: Bedienung intuitiv, gute Reaktionszeit. Das neu anordnen der Symbole braucht etwas erfahrung, da kein "Drag and Drop". 4 Verschiedene Oberflächen, viele Infos auf einen Blick. Das Starten ist mit dem "Fahrenden Twizy" auch sehr gut gelungen. Etwas ähnliches würde ich mir beim Abschalten (von alleine nach etwa 4 sek. nach dem Twizy) auch wünschen.

"Probleme": Die Temperaturanzeige scheint mir nicht ganz zu stimmen. Ich habe zwei verschiedene Temperaturen gesehen (28 und 12°). Beide können nicht so ganz stimmen, der Twizy steht in der Garge (8°) nicht gefahren oder geladen. Das Twizometer habe ich aus dem Haus (21°) geholt. Daher muss dieses 21° oder kälter haben.
(Vielleicht ergeben sich die Temperaturen auch später noch, wenn ich mal richtig gefahren bin)

Überraschung: Das Twizyometer funktioniert mit dem ediver BMS und dem Catl genau so, wie mit der Originalen Konfiguration. Es zeigt 9.7kwh an und auch die Zellspannungen können abgerufen werden. (Das schafft nicht mal der Renault Clip!)



Anregung: Eventuell macht es sinn, den SOH nicht immer auf der ersten Seite stehen zu haben, noch schaue ich mir diesen gerne an (bei #1 100% und bei #2 100%), fällt dieser aber später mal, möchte ich mir nicht ständig das "elend" ansehen müssen

Alles in allem bin ich super zufrieden damit. Ich werde damit viel Spaß haben und endlich auch ein (besseres) Twizyplay besitzen

Danke Fabio!

Englisch:

Here is a short conclusion after a first test (so far only in the garage because the weather is too bad for me and my Twizy.)

Processing: Top, you can't imagine it better for a hobby project. All edges are rounded, no traces of "damage" or similar.

Installation: Very easy. I only wired it loosely at first because I wanted to test it in several vehicles.

Function: Intuitive operation, good response time. Rearranging the symbols needs some experience, as there is no "drag and drop". 4 different surfaces, lots of information at a glance. Starting with the "Moving Twizy" was also very successful. I would also like something similar when switching off (on its own after about 4 seconds after the Twizy).

"Problems": The temperature display doesn't seem quite right to me. I saw two different temperatures (28 and 12°). Both cannot be quite right, the Twizy is in the Garge (8°) not driven or loaded. I got the Twizometer out of the house (21°). Therefore, this must have 21° or colder.
(Maybe the temperatures will come up later, when I've really driven)

Surprise: The Twizyometer works with the ediver BMS and the Catl just like with the original configuration. It shows 9.7kWh and the cell voltages can also be called up. (Not even the Renault Clip can do that!)



Suggestion: It might make sense not to always have the SOH on the first page, I still like looking at it (at #1 100% and at #2 100%), but I don't want to look at it later constantly have to look at the "misery"

All in all I'm super happy with it. I will have a lot of fun with it and finally have a (better) Twizyplay

Thank you Fabio!

It's me to be very happy about your first feedback!

Each page, except info battery pages, is fully "customizable", i.e. you can choose what data have to be showed, within the ones available.
To do that go in setup page (three dots) and proceed as follow:







In this way you can remove SOH from the first page and swap it with another data.

Three temperature are available: motor temperature, battery temperature and internal (car) temperature. The only which can be not affordable is the last one, because it's taken from the gyro's temperature sensor which is affected by the microclima inside the blackbox.

Be assured, that there will several feature requests.
I promise (or threaten?) to you.

Plans for the future...
I share my dream list about this project. Yes, they are only dreams that could enter in the to do list, but as I'm not sure to start them, I can promise nothing.

Dream List
1) WiFi connection to send data relying on MQTT broker, for home integration
2) a very (very, very, very ) basic android app, for pushing notifications (charge started/completed, for example)
3) some little icons on the bottom side of the display, like the ones in the notification tray of an android phone, for warning purposes (motor/battery overheating, connection lost, low battery charge, etc...).
4) good-bye screen/animation at power-off (thanks to JPB for the idea)
5) trip info page, with current usage, estimated km left, kWh per trip etc. (thanks to HollandHannes for the idea).

To be clear: don't create any expectation about the above "dreams" and not decide for Twizy o'meter trusting these dreams will become true, because, you know, often dreams stay dreams and don't become true!

For now I can only say that:
- dream 1) is in working progress, at 50%
- any improvement will be available by a firmware upgrade, with no hardware modifications. So, extended to all Twizy o'meters.

I'm interrogating myself if I have to thank you, or not...

@Ulli-and-Tom: I'm sorry, but the onfly german to english translator I use, translated also your nick name and I didn't realize about.

JPB schrieb: It shows 9.7kWh ....

I didn' think at the biginning: I calibrated min/max range of battery kwh without considering someone could have a bigger battery then standard one (6.1kwh).
So you'll have a graphical rappresentation of 100% kwh starting from 6.1 kwh.
The issues will be fixed in the next firmware, adding a specific setting in setup page.

I find it is extremely practical if larger capacities are also recognized . Many Twizydriver will probably switch in the coming yearsto the larger CATL battery.

Point 1) of my dream list is becoming a nightmare!
This implementation is more difficult than expected... but I go on.

I received many request to anticipate point 5) of my dream list, before other points.
So while I'm working on Wi-Fi connections, I want to open a poll about what you would like to see in Trip info page.

I guess it could be usefull:
1) trip time (the elapsed time from start to stop Twizy)
2) average speed (calculated: km. traveled / trip time). Do you prefer travel pauses are removed from calculation?
3) kwh consumed (calculated: kwh available at start - kwh left at stop)
4) estimated left km autonomy (calculated: kwh consumed / km traveled * kwh left). Is there a better algoritm?
5) km traveled

What else?

Delvecchio schrieb: What else?

Charging power - with how many kW it is currently charging (if not already available)

Best regards Tom

They have Stolen my Twizplay and search an substitute.
Do you still have some of these?

Best regards

THOSE RASCALS!!!!!!!!!!!!!!!!!
