Re: SOC-Meter Improvement Suggestions

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!
