Hi guys, I just wanted to give you a quick update on my reverse engineering on the Tazzari Zero CAN-Bus. I've put together the Y-Cable-Adapter to attach the service-console as well as the USB-Interface to the Bus (see picture attached). As my dealer needs to get back his tools I borrowed, I wasn't really able to dive deeply into the messages, but I found the SOC and a charge-status that indicates whether or not the car charges. I will hopefully be able to write down all values that are provided by next week. LevAhR This is the state of charge in percentage Request: 0x78A 75 21 F9 EF Response: 0x775 0A A1 F9 EF 00 00 03 E8 Value 100.0% 03 E8 represent 1000 = 100.0 % SOC ------------------------------------------------------------- Charge Status Values to determine whether the car charges or not. Request: 0x78A 75 21 F6 E0 Response: 0x775 0A A1 F6 E0 00 00 00 63 Value "reset" (not charging) 0x775 0A A1 F6 E0 00 00 00 00 Value "SUV" (charging) Note: there are more than these two values while the charging comes to an end. I'll know them soon. But for now !=reset should do the job for charging true. I'm still searching for a way to tell if the car is parked or not. As far as I know by now there is nothing on the Bus that indicates this. Is a GPS-Based determination generally possible? The OVMS would have to check the coordinates periodically and compare them. A charging process indicates a parked car as well, and could turn of the GPS comparison. Regards, Patrick Kapsch
