Battery temp readout

[George S. Bower]

I would like to be able to get my battery temp displayed.

Have any of you figured this out. I'm sure I'm not the first to want it.

Can one pull battery temps w/ the dashdaq or is MDI the only way to get the data??

Thx,
GSB

Check the DashDAQ/OBD2 threads, linked from the FAQ, down at the bottom.

This is a bigger issue with Nissan Leaf users, without a thermal management system, which is why I suspect they include it with the Leaf, and the Volt doesnt have it.

I'm sure it's been discussed before, but there are several variations on battery temp available on DashDAQ - min cell temp, max cell temp, average temp, and I think one or two more. Watching average the last few weeks, it hasn't done much. In the 90-100 degree heat last week, it was 77-81. These last couple days with 50 degree mornings, it was 77...

Thx for the responses Hi ChrisC,

Saghost,
I thought I read that the new Dashdaq they took out the ability to see battery data

I believe that Rusty was discussing with Drew technologies the content of the Volt package, and playing with a few beta versions. I'm not sure what is in those, or whether they've changed the official release package recently. I do know that my DashDAQ shows several battery temps.

Hi George, congratulations on your new Volt! I'm curious as to what you will do with the information. I spent my life as an automotive engineer measuring all sorts of things, but it was always pointed at controlling whatever system I was monitoring. As far as I can tell, the Volt engineers have it pretty well covered and under control, and the user has very little that they do to modify the way the car works. You have partial control of how the energy is used, but only partial with other things that you can't really influence. In my retirement I have decided to sit back and not think too much about what is going on other than be amazed at what they have accomplished with the brilliant Voltec package. My hat is off to them - now get working on incorporating it into other platforms

You guys are probably correct. It might be a boring piece of info. It might be interesting to see how many kwh it was taking to cool the pack though maybe as a function of ambient temperature.

I don't know that I have a way to measure that. By having DashDAQ do fancy math I can get overhead& accesory loads and HVAC and wire losses commingled (subtract MGA and MGB power from Battery power - could possibly pull out 12V bus separately, since the APM reports 12V bus current&voltage.) I'm just not sure how to separate the remaining bits, unless there are data fields relating to it I'm not aware of.

Thx AZ
(more Volts in AZ than I thought)
