WiCAN - BYD Atto 3 add more parameters

[Ipirk88]

Hello,
fist of all - to read out the SoC of the Battery is verry easy and works just fine - thanks for that!

But i whant to know more about my car :-)

Is it maby possible to read out more parameters for example:

• min/max Cell Voltage to calculate the voltage spread between the cells
• Battery total Voltage
• min/max Cell Temp
• driven km
• charge Power that goes into the Battery (to calculate the Charge efficency or what is used for the rest of the Car - Heatpump)
• Voltage of the 12V battery

And one Question more - does the WiCAN also support the BYD Seal U?

Thank you so much!

@Ipirk88 I've add the battery voltage, you should sync the profile and reboot. For the other parameters we need to look at the logs from car scanner.

Do you see the other parameters in car scanner?

[meatpiHQ]

Yes the BYD seal U should be the same profile.

Great - thank you very much - I have this Car Scanner logs:
2024-12-07 18-05-23.csv
Did you need another one or is this enough?

[Ipirk88]

sorry wrong file - here is the correct one
2024-12-07 13-12-19.csv

@Ipirk88 please export the logs for each value, lets start with driven km (odometer). In car scanner click on the sensor and let it run for some time, make sure to note the value at the time of reading.

OK - so how to do? I don't get it fully?!

So first connect, than go on "all Sensors" then click on the sensor?! Is that right

Is that right? And than?

@meatpiHQ I updated my profile and now have the HV battery values except in HA it shows as 40000 instead of 400v

Ill have a look at doing some logs of the values I'd like to see
