Testing of false 12V alerts was successfully. No false notifications has arrived from my Think City.

The conclusion is that car_doors1bits.CarON and car_doors5bits.Charging12V have to be correctly sett according to the 12V-battery charging state and car-state (in the vehicle-specific file).

No changes have to be made at net.c (car_12vline_ref -15).

I have now rolled back locally the net.c to «car_12vline_ref - 15» and added 

car_doors1bits.CarON = 0; 

car_doors5bits.Charging12V = 0;

to vehicle_thinkcity.c when:

- discharge is not allowed AND charge is not enabled

In addition to car_doors5bits.Charging12V = 1;  when:

 - charge is enabled

 - End of Charge is detected AND plug is attached

Some quick tests gives positive result that no 12V Critical Alert is send.

I’ll keep you posted.

False 12V alerts disappeared when triggering alert from ref - 2,0V.

    // Trigger 12V alert if voltage <= ref - 1.5 V:
    if (!(can_minSOCnotified & CAN_MINSOC_ALERT_12V)
            && (car_12vline <= (car_12vline_ref - 20)))

When setting Notifications (parameter #3) to "IP" or "SMSIP" I finally receive alerts - including Minimum SOC (feature #9) ;)

The 12V Critical Alert triggers quite often, even if my 12V-battery is new and in top condition.
I've measured that the car_12vline reports ~0,5V less than the real battery voltage, so I plan to change the file net.c (line 1458) from:

 
   // Trigger 12V alert if voltage <= ref - 1.5 V:
    if (!(can_minSOCnotified & CAN_MINSOC_ALERT_12V)
            && (car_12vline <= (car_12vline_ref - 15)))
    {
      can_minSOCnotified |= CAN_MINSOC_ALERT_12V;
      net_req_notification(NET_NOTIFY_12VLOW);
    }

to:

    // Trigger 12V alert if voltage <= ref - 1.5 V:
    if (!(can_minSOCnotified & CAN_MINSOC_ALERT_12V)
            && (car_12vline <= (car_12vline_ref - 20)))
    {
      can_minSOCnotified |= CAN_MINSOC_ALERT_12V;
      net_req_notification(NET_NOTIFY_12VLOW);
    }

and compile it to a local hex-build and test in on my Think City.
Keep you posted about the result.

Best regards.

Can someone try it at 2.0V (rather than 1.5V) and see if it solves the false-alerts problem?

Regards, Mark.
