Torque pro battery capacity guess...

Sat Jul 27, 2019 12:24 pm

Battery capacity guess isn't showing a value in torque pro with the bolt pids loaded. Are you all using different pids that call it something else? This is on my 2016 spark. Thanks!

Did you set up your screen to show the battery capacity PID? I am successfully using TorquePro on both my 2014 and 2016 Spark EVs and battery capacity is one of the parameters I check and plot all of the time.

Yeah its loaded on my screen as "Bat Cap Est" or Battery Capacity Guess. When I choose more gauges to show and scroll through the list it shows some values active/displaying data. I can even see individual cell voltages, but the battery capacity gauge doesn't show any value in that list or when added to my dash.

The equation for the bat cap Est is ((A*256)+B)/30

Is that the same equation for your display if you were to try to edit the pid?

Thanks!

Is the car turned on? Some values won't display otherwise. I can't remember whether the battery capacity is one of those.

Edit: I just went out to the garage to check. The car doesn't have to be on for the battery capacity to be displayed. I'm using ((A*256)+B)/30.

Battery Capacity: PID 2241a3 ((a*256)+B)/30 unit: kwh
SOC: PID 228334 (A*100/255) unit: %

I have to have the car powered on to get any readings.

What if the 12V battery had to be replaced and the car hasn't had a full charge/discharge cycle, only been driven about 12 miles since the 12V battery replacement. Would that have an effect on readings/estimations in torque? SOC raw does work for me.

Maybe coincidence, but it LOOKS like all PIDs with header 7E4 are non-functioning. Will check/play with that header value to see if I can get it showing.

Replacing the 12 volt AGM battery will not have any effect on the TorquePro readings. TorquePro will read the PID information the car keeps stored in its computer memory.

Bah, swapped out my bluetooth adapter for an ancient one I found in the bottom of a drawer and it's working now!

Now for the bad news. 2016 with 28k battery capacity is 14.4kw, ugh. Should I return this one to Carvana and try again?

The real question is this - does the car meet your driving needs? At 5 mi / kwh, you have a estimated maximum range of 72 miles. My 2016 Spark EV with DCFC and 22.5k miles has a current battery capacity of 15.8 kwh although it has been as low as 15.4 kwh. At 15.8 kwh and 5 mi / kwh, I have a estimated maximum range of 79 miles.

Every Friday, my wife and I have to make a 130 mile round trip that requires a DCFC charging stop each way. Because of the current hot weather, we also have to use the AC on our way to our destination. Obviously, without the DCFC chargers, I could not make the trip. Driving in town is not a problem as I have L1 and L2 chargers in my garage. And, in the town where I live, we also have two free L2 EVSEs but no DCFC stations. The closest DCFC station is 10 miles away but it is currently down for repair.

I also have a 2014 Spark EV without DCFC and my current battery capacity is 15.9 kwh with 19.4k miles on the ODO.

I guess my answer is yes, for 90% of my needs it would be fine. There are times when I'd want to drive it 65 miles for a day trip and charge while there, then 65 miles back. The BACK is what I'm concerned about as it's a 2000 ft elevation gain toward the end of the trip.

With Carvana I have until Friday to decide if I want to exchange the car for FREE. What are the odds that another model would have LOWER battery estimate? I'm not seeing much in the lower 14kwh range at my mileage 28k, seems to be on the edge of abnormal? Thanks for your input!
