Probably the 4 individual temperatures may not come out of the BMS, but at least one temperature must be in the EV-CAN for the dash to display the temperature bars. Is it allready identified?

I noticed a "feature" with the SOC-meter firmware that I'm not aware if it is allready addressed. When doing a QC the charge current goes above 99.9A (up to 125A, I guess) but because the display only has 4 digits it stays as -99.9. Is it possible for charging currents above 100A to drop the decimal point so they can be displayed?

Pack Temp:
Not yet identified.

CAN-Do shows 3 values that are candidates for temperatures,
but nothing conclusive yet.

Pack-in current:
Yes, in Ver F1.08 I limited at -99.9 amps, but I will try to
shift to a -100 amp (no decimal) when at 100 or over.

Adding a Friction-Braking Buzzer:

1. We (think) we know the CAR-CAN Message and field for Friction Braking.

2. When switched to the CAR-CAN bus (instead of the "normal" EV-CAN setting) the SOC-Meter can read the Friction-Braking message.

3. A low-power 5v buzzer, activated by the uP on the AVR-CAN board, could be added to the SOC-Meter circuit to "indicate" when Friction Braking is active.

4. Once we have these, new firmware could "buzz" us.

The only missing link is the selection of an appropriate "buzzer". TickTock might be helping develop and do testing on this new option for us.

Open to suggestions!
