    I'm posting this separately from the V7 firmware threads, as those seem to have become a bit more about the overall layout, etc... And I'm not sure this is a v7 thing at all, as I've not driven this far down recently.

    When I first got my car back in the V4-5 days, I had occasion to drive it down to 0 once, and at as I got to zero (perhaps slightly before) the dash range display indicated I needed to charge immediately:

    I've not driven it that low since. About a month ago I got it down to 6 miles on a road trip, and that gave me the typical navigation planning warning of needed to drive slowly, and charge to reach my next destination, etc... but no red dash message. But then again I wasn't at 0. That was on v6.2.

    Yesterday I drove it down to 0 again (on purpose for a calibration test), and no such indication:

    So I'm wondering if that red range-display message has been eliminated entirely? I note that the power-limiting line in the energy gauge is at about the same place in both pics.

    I actually parked it and ran the heater for another several hours, I did get a couple of "HVAC power reduced" messages, and the energy limter line eventually dropped to about 20KW before I plugged it in[1].

    Has anybody else driven to 0 an noted similar UI behvaior change?

    [1] Interestingly, it would only charge at about 5A for the first 20 minutes or so before ramping up to the full 40...

    If making the battery icon and range numbers smaller and moving them off to the corner was intended to lessen the "EV-ness" of the car to make it less intimidating for mainstream buyers, this is carrying the idea too far!

    I would expect the battery icon and 0 mi to start flashing or something to get your attention.

    Guessing your 12V battery needed a charge cycle after this run down using HVAC, so it recharged your 12V battery first, before charging the main pack.

    5A is enough for the DC-to-DC converter to run.

    Ah, that makes sense. As a matter of fact, I believe a low 12V warning popped up as well.

    Learned something new... thanks.
