Hello,
I have just installed an OVMS V3 module in my Nissan Leaf ZE1 (40 kWh).
Hardware installation appears correct and the module communicates with the vehicle CAN bus.
Current system information:
Vehicle: Nissan Leaf ZE1 (40 kWh)
OVMS hardware: OVMS V3
Modem: SIM7600 LTE
SIM card: Hologram IoT (network: Vivacom Bulgaria)
Firmware version: 3.3.001 (Dec 2021)
Observed behaviour:
• Cellular connection works (modem registers on network)
• Battery voltage is detected (~386 V)
• Odometer is read correctly
• OVMS mobile app connects to the vehicle
• However SOC shows 0%
• Some values look incorrect (regen %, cabin temperature ~51°C)
• Server connection sometimes shows “Last seen X minutes ago”
I suspect the firmware may be outdated for Nissan Leaf ZE1 support.
Questions:
-
What firmware version is currently recommended for OVMS V3 with SIM7600?
-
Should I upgrade to the latest "main" or "edge" firmware?
-
Are there any required configuration changes for Nissan Leaf ZE1 (SOC / GIDs settings)?
Any advice would be greatly appreciated.
Best regards,
Ivan Hristov
