Maxus T90EV

Hi all,

I’ve got a Maxus T90 EV (UK) and I’d really like to get it supported in OVMS.

Core priorities (the features I’d really like to see supported):
• Battery level (SOC)
• Charging status
• Odometer
• Lock/unlock state

Known working PIDs (sent to me by Marius):
0x362 / 0x540 → Odometer
0x7e3[7eb]:e002 → SOC
0x7e3[7eb]:e003 → SOH
0x281 → 0001 locked / 0000 unlocked

Additional PID list (useful for extended support):
0x266 – Steering wheel position (left / centre / right)
0x281 – Lock/unlock, indicators, ignition stages, reverse gear
0x355 – Seatbelt status bits (driver, passenger, rear)
0x375 – Door open/closed state, lighting state (park, dipped, main, fog)
0x510 – HVAC airflow mode, fan speed, set temperature, AC on/off, recirc, defrost
0x6F0 – Power range / energy related
0x7e3[7eb] – e002 = SOC, e003 = SOH

Additional vehicle details:
• Maxus T90 EV, UK spec (2023 model year)
• Standard OBD-II connection (using OpenEnergyMonitor OVMS Wi-Fi/4G module)
• CAN bus accessed via OBD2 port
• Charging state PID not confirmed — may need indirect detection via SOC change

Testing context:
• Signals observed during normal driving and ignition transitions
• Steering, lighting, HVAC, and door states appear stable and repeatable
• SOC and odometer readings confirmed reliable

Main goal:
I’d love to see basic support added for:
SOC reporting
Charging state
Odometer
Lock/unlock status

There’s additional data above for anyone who wants to implement extended functionality (HVAC, steering, lighting, etc.).

If anyone is willing to take this on, I’d be wiling to contribute where I can. I've been trying to do a build but I'm hitting issue after issue trying to build it on my Mac. Is there anyone that can help please? I've been pulling my hair out for days just trying to get a successful build.

Cheers,
Keiron
