    I tried for several times to get the contact of european R&D Team for changan OTAs but never get any answer to my requests ... no matter what I try they seem to be a closed box that don't care about feedback from costumer's. It's really bad this posture for the brand. I even try to get feedback from the chinese but without success, I made contacts with many divisions in Changan but no luck until now.

    If you use CarScanner and at the end export the data to a csv will be enough for analysis. As long as you have all the parameter's to record in the dashboard.

    I am using too CarScanner and ABRP this is the best combination in my opinion.

    To do road trips in Europe I suggest to do two subscriptions: Ionity & Tesla during that time, then you cancel them. After 2 or 3 charges you start getting provit of it. Ionity network is good in Portugal but the payments aren't as easier as in the rest if Europe ... let's say ... business opportunists. Likewise, you don't need to care about best prices and so on... the best one's are from Tesla with subscription.

    Hi,

    From what I tested it seems Changan hasa different approach about it.

    They kept the battery in a stable temperature interval all the time. Therefore, the precondition don't make sense and isn't needed. To be able to do that a good engineering and architecture of the system must be in place.

    What I have seen? Temperature of the battery goes from 25 to 38 ºC. When the vehicle is being used it goes from 30 to 38 ºC. When charging in a DC public charge I saw the charging curve being followed. [Blockierte Grafik: https://evkx.net/models/deepal/s05/s05_rwd/chargingcurve/chart/?battery=0&theme=dark]

    Which means all the times I charged in a DC the charging rate is aligned with that curve.

    I have more parameters for CarScanner that I can share with you ... I just need to export the dashboard, the sensors customized by me and then you can import them on the app.

    Well that will be easier ...

    1. Open CarScanner

    2. Click on connect in the app

    3. After connection done (remember you need a compatible obd2 device connected in the car), go to Settings - Sensors - User created (custom sensors) - Create a new one with the this config ...

    Name: [BMS] SOH

    Short name: bms_soh

    Command: 22F264

    Header: 7A1

    Formula: 100-A/68

    Minimum: 0

    MAximum: 100

    Units: %

    ....

    4. Add this sensor to a dashboard

  • Reverse Engineering to know what I bought

    I have done some reverse engineering and this is a work in progress ... the discoveries are at https://github.com/jpires71/Deepa…/main/README.md

    Due to my collaboration with ABRP and CarScanner ... we are able to get good integrations, but in a near future I believe those will improve based on their work and of the information that I shared with them.

    When I bought my car ABRP and CarScanner weren't able to have a real integration with the car. Then I bought a two OBDC2 (Vgate Pro 2S and another one from China) and I created the python code needed to connect to the car. Collecting data and using AI to help me through do the improvements and analysis. In that way, I am able to get info from the car like SOH, EFC, etc.

    I reported to Chagan that until version 3.0.2 the SOH was wrong. Then in the version 3.0.3 they changed it for SOCE.

    If anyone wants to learn, know more or share ideas and knowledge feel free to reach me out.

    I am from Portugal and I got the 3.0.3, but from my view it was a kind of a downgrade cause some fixed bugs in the 3.0.2, came back to the same status as they were in 3.0.1.

    Moreover, the R&D team don't seem to be very pro cause some errors are mainly due to lack of testing and bad decisions taken.

    The idea should be simplify and not over complicate the end user experience.
