I wonder how long one can leave the adapter plugged into the OBDII port before the battery drains. I noticed that even when the car is off, the OBDII port will keep the adapter powered on.

I've not noticed any drop in battery, and I've had mine plugged in for over a week. I suspect it's such a small drain, the 12V battery doesn't mind. I would probably unplug when I go on vacation though.kubel said:I wonder how long one can leave the adapter plugged into the OBDII port before the battery drains.

You'll notice battery > 66, which seems odd.kubel said:JeremyW said:Did anyone else notice the 101.67% capacity reading? :shock:
Wouldn't that imply > 281 gids? My guess is gids aren't quite as magically absolute as people have suggested. Either that or MY2013 is hiding a secret. Great, now I have Mr. Roboto stuck in my head.

Aren't gids just soc * cap * 300?garygid said:The test (no-connection) cell-pair Voltage data has CP 59 low
at 3.990v and CP 72 high at 4.920v, and the rest 4.000?
Trying it on my Vizio Android tablet, and I will try with the ELM327
adapter tomorrow.
If it works, it is another item for the Show-n-Tell on Saturday in San Diego.
Too bad we do not have GIDs on the CAR CAN bus.
Thanks, Gary
Gary, This is not the case. The ELM327 can only see the CAR-CAN and the CAR-CAN does not need to be active before a pack request is sent. It is the EV-CAN that must be active to handle the pack request. You can send the pack request to a CAR-CAN that has no activity at all just as long at the EV-CAN is active. An inactive CAR-CAN can still pass the message over to the EV-CAN and the EV-CAN can route the response back to the idle CAR-CAN for the ELM327 to capture.garygid said:The app could wait to get some first CAN passive message
before it tries to write to the car, requesting information.
Yes, this is test data. The other two are set to test the auto scale upper and lower values and to give a 30mv difference. As people have noted, reading the same pack again always gives a slightly different value for all cells.garygid said:The test (no-connection) cell-pair Voltage data has CP 59 low

The simple answer is no. But Gary can give more details. They are named after him ;-)sirfergy said:Aren't gids just soc * cap * 300?
In the near future, I will be measuring the current in the ones I have. But they do get warm to the touch.kubel said:I wonder how long one can leave the adapter plugged into the OBDII port before the battery drains.

I seem to remember from the ELM327 data sheet that it has a sleep mode. I wonder if putting it to sleep before exiting would have a significant effect on current draw.
