Torque in a Prius (2004)
 

Just wanted to chime in that I have been experimenting with the $5 version of torque in the prius, it is completely awesome, and crazy cheap if you have a bluetooth android (gps would be a plus also):

So trying to understand what the prius is doing is a lot easier now, I might even be able to have a soft button on my android for a kill switch 8-o

Currently I have 6 gauges on the main screen,
1. mpg graph
2. ICE load (mostly a "the engine is running" indicator, and I try to keep it in the 60-70 range when it is running)
3. HV battery hp (goes negative when charging)
4. brake friction pad hp (so I can tell when I have exceeded regen and am just making heat).
5. MG1 hp
6. MG2 hp

It is pretty awesome and so affordable and so easy. I don't know how accurate it all is, but I'm geeked to have some good insight into where the power is going.

Are you able to see the high voltage hybrid battery module voltage data with it?

Not just overall voltage of the pack, I mean the actual modules.
There are 14 "blocks".

See this post on Priuschat and the one after it

Apparently so, per http://api.viglink.com/api/click?for...13631276531762

14 blocks, 0-18 volts, internal resistance per block as well, though I don't know about logging from torque, but the elm protocol is simple enough to hack something together on a bluetooth laptop for battery health monitoring or so.

Well, for starters it may be interesting to simply read.

For logging, perhaps I'd get a a usb version as well.
Have you seen any other good ones on ebay that are as cheap as the bluetooth one you chose?

I am just using the one adapter, I have considered using an fdti usb cable to the elm chip therein, but have enough bluetooth computers/devices that I probably won't mess with it. I have talked to the adapter via some terminal program on ubuntu.

there is a lot built into torque for logging, uploading, graphing too I am finding now...

My laptop does not have bluetooth, though.
And I don't think my tablet, which has bluetooth, would be powerful enough for logging data. I'll have to research it a bit more.

bluetooth adapters are literally less than a dollar, fyi

Good to know. Thanks.

I sent the developer a message hoping for a clue on how to shut off the engine via obd/soft button, that might be a long shot, but I did find some useful "indicator lights" where I can see when something else requested the engine off (or idle, or warmup, or off lockout?).
