Display vampire drain rate for my vehicle

mkolowich 2 years ago • updated by TESLEV1 3 weeks ago 9

Helping car owners to understand/estimate vampire drain would be a major help. This could be done in several ways:

  • with data display (I.e. when idle, display current vampire drain rate [lost range, in miles/day] in top status bar)
  • with graph (i.e. show bar graph of vampire drain rate [lost miles / day] for different connection states (connected, sleep, deep sleep))

Even more importantly, I think it would be a great service to run a regression, across the entire database, to discover exactly what influence each of the following has (if any) on vampire drain rate [lost miles / day]:

  • connection state (connected, sleep, deep sleep)
  • state of charge (current % charge level)
  • outside temperature
  • battery size (kWh max capacity)
  • car model (S, X, SP, XP, 3)
  • time since last charge

The results would help car owners understand exactly how to minimize vampire drain on their car, and to understand, for example, how much vampire drain to expect when, say, parking their car at the airport during a three-week vacation

One source that I noted after cursing at my car for not going to sleep today as it heated up.. Cabin overheat protection. It seems that having this on wakes the car up when it hits 105F and it'll refuse to sleep during this period. I thought my wife was poking at my car all day keeping it awake. Then I realized I had this on, ran out and turned it off and the car fell right asleep. Just something to keep in mind if you turned that feature on.

I'd also like the ability to tie vampire drain to specific builds. I'm envisioning some sort of pivot table functionality.

Even the settings around sleep are someone convoluted... so much trial and error to see what works.  Simplifying that in any way would be appreciated.

I would like to see the average power during the sleep.  KW-hr used during the sleep period / the sleep period in hours

If this feature is implemented I'd like to be able to set a range of time to analyze - the behavior of my car over the past few weeks or months (or on the current firmware version) will be a better indication of what I can expect than the lifetime behavior.

I think it would be great to graph idle time range loss (as shown each day in the right column) vs. temperature, similar to the drive efficiency vs temperature graph. I noticed that I have 20-30 miles of range loss each day but right now I can only see that clicking on each individual day. It would also be nice to see this number listed for each day on the calendar.

would be helpful to measure battery heating power

I'd like to see a graph showing actual miles driven vs. rated miles.  This would help drivers determine actual battery mileage needed during colder months.
