I think I found the bug, please use the attached new version
instead.<br>
<br>
I'll also test that one myself later on today.<br>
<br>

PS: your posts are great to read! I also like your idea for a
permanent installation place of the OVMS, I still have mine in the
glove box.<br>

I have added these fields to the RT-GPS-Log message:<br>
<br>
// current power (W)<br>
// power usage sum (Wh)<br>
// recuperation sum (Wh)<br>
// distance driven (m)<br>
<br>
Be aware that the "current power" is really the power use of the
exact moment the message is sent, no average. This reacts to any
bump in the road or wind gust. So the sums will normally be more
useful, but will need deriving the section differences in a post
processing step.<br>
<br>
New firmware image attached. So if you activate GPS streaming
you'll get updates every 5 seconds, which should already give a
very detailed view of the power usage (if GPS position can be
acquired fast and precise enough).<br>
<br>
I had a strange effect (read: possible bug) on the first test run:
distance would start at 6546 meters (should be 0). That could have
been because I was very fast with flashing so maybe the SRAM init
was skipped... but maybe it's a real bug. If it's a bug it will
also affect the power usage statistics, resulting in too low Wh/km
figures.<br>
<br>
Please tell me if you still see a similar fault if you wait 2-3
minutes from flashing to reinstalling.<br>
<br>
Thanks,<br>

Instantaneous power should be available in most cars. It is
certainly there in the roadster (because we spoof it to show
speed as a digital speedo).

</div>
<div>It would not be hard to add it to the model and to the
location streaming feature when an App is connected.</div>

quite easy to send power usage updates within the
streaming update mode, just adds some traffic. So you
would get 5 second sections in GPS and power usage,
easier to correlate. But still the power usages would be
far easier to process when being included in the GPS
messages.<br>

Nikki, Mark,<br>
<br>
I decided against adding the current power to the GPS
log because that's something not defined in the
general virtual car model, all other cars lack this
feature, and I wanted to make the GPS log function fit
for inclusion in the framework first.<br>
<br>
I currently send the power usage log
(RT-PWR-UsageStats) once per minute. You can correlate
that to the GPS log to get the power usage of minute
long sections, but that's a lot of manual work and not
very detailed (e.g. for hills).<br>
<br>
Btw: using the power collection feature, you can also
measure certain route parts: easiest way is to turn
the Twizy on just before driving the section, then
turn the Twizy off and check the power stats message.
But a combined GPS track would of course be far better
and more accurate.<br>
<br>
Mark, you mentioned a "kWh used" value with the
driving log function, so I guess we can think about
adding the power usage to the standard car model?<br>
<br>
But I'm not sure yet if the way I currently collect
power usages is suitable and sufficient as a standard.
As I wrote in the docs, that's work in progress... any
thoughts on this?<br>
<br>

<div>One thing that's missing, which I'd love to see
