Decyphering iMiEV and iON CAR-CAN message data

[CZeroOwner]

The VIN number is coded in the 6FA PID

6FA: byte(1) = 0 Char(i-1) = ASCII(byte(i-1)) VIN first 7 characters
6FA: byte(1) = 1 Char(i-1) = ASCII(byte(i-1)) VIN last 7 characters

In case anyone ever does it:
MeatPi wiCAN interface, sends CAN Data via MQTT to home Assistant. Node Red Subscribed to topic.
Function with 16 Outputs sends iMiev Data to Home Assistant for automation.
Note, the IDs are in decimal.

Here is the code for the function:

var SOC1, SOC2, Battery100Cap, CellMaxTemp, CellMinTemp, BatteryVolts, CellMaxVolt, CellMinVolt, ChargeAmpsAC, ChargeAmpsDC, ChargeVoltsAC, ChargeVoltsDC, ChargerTemperature1, ChargerTemperature2, Odometer, OutdoorAirTemperature;

for (let i = 0; i < msg.payload.frame.length; i++) {
    let frame = msg.payload.frame[i];
    let id = frame.id;
    let data = frame.data;

    switch (id) {
        case 884:
            SOC1 = { payload: (data[0] - 10) / 2 };
            SOC2 = { payload: (data[1] - 10) / 2 };
            Battery100Cap = { payload: data[6] / 2 };
            CellMaxTemp = { payload: data[4] - 50 };
            CellMinTemp = { payload: data[5] - 50 };
            break;


        case 883:
            BatteryVolts = { payload: (data[4] * 256 + data[5]) / 10 };
            CellMaxVolt = { payload: (data[0] + 210) / 100 };
            CellMinVolt = { payload: (data[1] + 210) / 100 };
            break;
        case 905:
            ChargeAmpsAC = { payload: data[6] / 10 };
            ChargeAmpsDC = { payload: data[2] / 10 };
            ChargeVoltsAC = { payload: data[1] };
            ChargeVoltsDC = { payload: 2 * data[0] + 0.5 };
            ChargerTemperature1 = { payload: data[3] - 50 };
            ChargerTemperature2 = { payload: data[4] - 50 };
            break;
        case 1042:
            Odometer = { payload: data[2] * 65536 + data[3] * 256 + data[4] };
            break;
        case 646:
            OutdoorAirTemperature = { payload: data[3] - 50 };
            break;
        default:
            break;
    }
}

return [SOC1, SOC2, Battery100Cap, CellMaxTemp, CellMinTemp, BatteryVolts, CellMaxVolt, CellMinVolt, ChargeAmpsAC, ChargeAmpsDC, ChargeVoltsAC, ChargeVoltsDC, ChargerTemperature1, ChargerTemperature2, Odometer, OutdoorAirTemperature];

hello,

looks like you guys know a lot about the can data, your information will realy help me.
thanks for that.

i'm currently trying to readout the OBC without a car, and i think i need some can data for that.
i do not have a car for recording myself at the time.
so i was wondering if someone got some can recordings i can try?


regards,
thijs
