I already had Torque Pro.
Set up the Bolt .csv info, and it seems.... off a bit.
Tried to measure charge rate on my Bosch 240V 30A unit today, and it only indicated 8 amps, yet was to be finished quite quickly. I wonder if that's BATTERY current vs. inlet current before the inverter....
Yes you would be correct about it being battery current, but there is no inverter involved besides the on-board charger's DC-DC converter boosting the volts and dropping the amps as a result.
Do you have a screenshot of your displays? If you want to see the AC voltage, AC current, and input power you should add a display that reads
"CAC Volts" where CAC likely stands for "charger AC"
"DCC PowerIn" which likely stands for DC-DC power input
what it sounds like you've added is the 'CDC Amps' which reports the output current flowing to the 2P96S battery pack. That would explain the 8 amps as high voltage DC, because the Spark EV's stock on-board charger doesn't have other input charge currents under 16A except for when it is completing a full charge or the 240V EVSE has reported to the car a lower-available charging current from settings or otherwise.
Here's an example of a past screenshot during 240V charging, where 8 amps DC appears on the CDC display, and 16 amps AC appears on the CAC display.
For what it's worth, you'd be better off using 'Min Cell' and 'Max Cell' which will sample all 96 series cells at once. This will let you just glance at the figures, and give you an idea of how much the pack is in need of balancing. Otherwise, it would be easy to miss such information regardless of how it was presented just out of the sheer quantity of cells you'd need to review.
Vehicle is indicating 13kWh estimated capacity on the battery, so I may need to take it to a stealership for a test (CA forced a 10-year battery warranty, I believe, so I still have some time to do this).
Let us know how it goes, lots of 2014 owners would be interested to know your experience. It would also be very interesting to see what condition replacement packs are in for the 2014 year as those cells are nearly one of a kind since the manufacturer, A123 systems, is now defunct. Hopefully replacement packs have been stored in a cold room and maintained at a healthy SoC for 7 or 8 years!
Bonus: Tried charging on 240V from home this evening. Forgot to try to check for charge input current, but it definitely added significant juice in only an hour. The adapter's good for 16A.
Makes sense, the Spark won't accept higher than 16A with its current hardware. After all, the fuses in the charge port are 20A...
Would also be worth checking how much voltage sag the EVSE has with 'CAC Volts'. I've visited some public chargers that have been as low as 190V and only received about 2.6kW!
