Communication problem with Fiat 500e (California) #256

Closed mif11k closed 3 months ago

mif11k commented 3 months ago

Hi, I used SmartEVSE-2 for several years with no problems (Smart and Solar charging). After I upgraded SmartEVSE to v3 I noticed there is a communication problem with American version of Fiat 500e. The car charges OK, but when charging is stopped regardless of who decides to stop charging (battery at 100% or no sun -> waiting for solar power) the car indicates charging error (two outer charging indicator lights). When the car returns the error and the charger wants to resume the charging process, it is ignored by the car until the door id opened (!!). So far I was not able to reproduce with any other car, that means, other cars can resume charging or when changing the mode Solar / Smart.

Here is the debug output while car reaches 100% at [19. 03. 2024, 7:27:34,350 PM]:

I tested with fw 1.8.0 and 1.7.2.

Upgrade to v3.5.0-RC1, that has improved on EV comms.

mif11k commented 3 months ago

You mean original 3.5.0-RC1? Does it also have Modbus/TCP support? Is there a prebuilt package, or do I have to build myself?

Thanks!

No that has been removed because the unsynced modbus calls disturbed the traffic between SmartEVSE's and their modbus connectes kWh meters...

dingo35 commented 3 months ago

Prebuild releases on github can be found on, you guessed it, the releases page:

https://github.com/dingo35/SmartEVSE-3.5/releases

(for some reason hard to find on mobile devices, on desktop it will show at the right side of your screen)

@dingo35 I can confirm everything works as expected on 3.5.0-RC2. When charging stops due battery full, charger transitions in "Connected to EV" state. Problem solved.
