A few people are working on the V5 software in their spare time (here)... hopefully they will get it working but for now V2/V3/V4 hardware/software is the most widely deployed and tested.
ok cool... is that the V5 software published on your GitHub in February?
So you are using a 120Vac supply? This has thrown up quite a few strange behaviours in the past.bulletbug wrote: ↑Sun May 24, 2020 10:06 pm I found a way to get 2 logs (serial and canbus) during the same timeframe. SavvyCan524.csvSerialLog524.rtf
Here are my settings:

Can you please just charge off one module (change enabled modules to 1, 2 or 3) then take a can capture and measure the current and voltage and provide these for further analysis.

1. Reverted to original copy of .ino file found here
https://github.com/damienmaguire/Tesla- ... rgerV4.ino
2. DC voltage reported on serial monitor as 518v. True pack voltage is 380v.
3. To fix this voltage reporting I modified scaler value on lines 822, 827 and 832 to cause dcvolt to display correct pack voltage on serial monitoring.
4. Other than that no other software changes are included in these results.
5. The EVSE (small portable charger unit from Chevy Spark) lists specs of 120v 60hz 12Amp
Thank you for your help.

Measuring with a clamp meter on the most negative end of the battery pack the current is low enough that it can be confused with noise. It is displaying between 0.00 and 0.05 amps. In tests where I've used all 3 modules with similar settings the clamp meter would show 0.15 to 0.20.tom91 wrote: ↑Wed May 27, 2020 8:20 amWhat sort of current did you measure on the DC side?bulletbug wrote: ↑Wed May 27, 2020 12:37 amI've done as you requested.

Yes give the 240V EVSE a test, as there is some comms over about the AC voltage and there are module firmware limits based on AC inputs.bulletbug wrote: ↑Wed May 27, 2020 2:26 pmMeasuring with a clamp meter on the most negative end of the battery pack the current is low enough that it can be confused with noise.

My clamp displays 2 decimal points and I've confirmed it is accurate by comparing to a DC power supply with another amp meter. They match readings down into the .05 range.
I also have a 240v 42 amp split-single phase EVSE mounted in a different location. If it would help I could retrieve that and test it under the same settings. Anything you need me to do or try, I'm good with. Thank you so much for your help.
I'm curious to hear if anyone else has successfully used 120v. I've taken new readings with the higher voltage charger and will post them next.Bryson wrote: ↑Wed May 27, 2020 5:00 pm It looks like your problem might be on the AC side in software as your limit is 10A and the serial output is reporting >10A AC. If this is all calculated from DC, it seems wise to trace those calculations back. Has anyone ever gotten 120V single phase running here? It might be something silly like an overflow in a calculation somewhere when AC voltage is in the 120 range. Just a thought, I don’t have my board to start debugging yet but operating on both 120 and 240 automatically is a must for me too.
Ok. I've rerun logs using the higher voltage charger. The EVSE is a Juicebox brand with wifi reporting. Watching the related app I'm able to get what I consider to be more accurate charging stats, voltage, amps, etc. Update cycle for the app seems to be in the sub-second range since it reports the HZ of the AC linetom91 wrote: ↑Wed May 27, 2020 3:36 pmYes give the 240V EVSE a test, as there is some comms over about the AC voltage and there are module firmware limits based on AC inputs.bulletbug wrote: ↑Wed May 27, 2020 2:26 pmMeasuring with a clamp meter on the most negative end of the battery pack the current is low enough that it can be confused with noise.

Settings527.rtf SerialLog527.rtfSomething that's not shown in these logs is that I've seen AC current (Input side) showing at 2.13 amp when AC line is completely unplugged. I'll start looking at your suggestion. I'm looking forward to getting Toms feedback as well.
Please report on accurately I see you mention AC read outs from the Juice box.bulletbug wrote: ↑Wed May 27, 2020 6:17 pm

Observed Amps: 0.8 amps stable
Initializes and moves directly to .8 amps and holds steady. I've rerun it several times, resetting the board, unplugging charger etc. and get the same results.

Correct but he was not measuring AC current but DC current. We are needing to redo the scaling as I mentioned.
