With time offsets that large you may also need to discard a series
that is stretched too far in time… or more generally, that stretches
over different load situations. But that would mean the data is
useless while driving, and I can't imagine someone at Tesla doing
nonsense like that, rendering real time data useless.<br>
<br>
Is it possible the readings are sent differentially (no change = no
tx)? Then you should get a complete set only when flooring the pedal
or starting/stopping a high power charge.<br>

Unlike a standard indexed message (such as VIN, for example) where
the messages come in #1, #2, #3, etc, these BMS messages come in
seemingly at random. For example, here is a capture from cold

</div>
<div>It seems that the individual BMS modules are reporting
these values directly onto the bus, with no centralised

message, that doesn’t really make sense (particularly for
voltage, with 6 readings per module).</div>

<div>It is quite simple to remove these out of range readings,

that improves it…</div>

filtering single readings or brick groups that way will

If you don't, the omitted cell will complete the series

<div class="">I think the temperature variances are

Obviously not working for you. Cells that

average get marked with "!", and "?" = warn
threshold exceeded.<br class="">

So at some point, many cells exceeded 200%

I changed the config scheme
hoping a manual configuration
normally isn't necessary with
this automatic adaption to the
standard deviation.<br class="">
<br class="">
Please check and report if that
idea works. If it doesn't,
please report the deviations and
necessary threshold levels on
your batteries.<br class="">
<br class="">
I also omitted the overall
stddev alerts for now, I don't
think those really are
necessary, haven't had a single
trigger on the Twizy for this.<br
class="">
<br class="">
Integration into the web chart
page and historical data updates
are still todo.<br class="">
<br class="">
Migration for the Twizy battery
monitor to the generalized
scheme is in progress.<br

Yes, you can add a new
menu to PageMenu_t
like that. I suggest
introducing a general
tools menu instead of
a specific one, i.e.
"PageMenu_Tools".<br

<br class="">
To still fit the menu
on one line in tablet

moving the Shell into
the tools menu then.<br

OK. I spent
some time on
this today,
and sent in a
first draft
(as a bunch of
extensions to
vehicle.{h,
cpp}). I
migrated the
Tesla Model S
code to use
it, and
support came
down to just a
few simple
lines of code.
<div class=""><br

</div>
<div class="">For
the moment, I
dropped the
idea of
‘readingsperrow’,
as I think
that is Tesla
Model S
specific, and
not really
necessary.
Purely
presentational.</div>
<div class=""><br
class="">
</div>
<div class="">c++
std::bitset is
fixed size, so
that doesn’t
work for us.
The
std::vector<bool>
seems a
workable
alternative,
but I am not
really happy
with using
std::find as a
way of looking
to see if we
have
everything. It
works as it
is, but is not
very optimal.
It seems there
should be a
better way of
doing that. I
think it is a
pretty key
feature, given
the broadcast
nature of the
buses, to help
the vehicle
module know
when it has a
set of data
ready to
commit to
metrics, so
will need to
think about
this some
more.</div>
<div class=""><br
class="">
</div>
<div class="">I
also
implemented
min and max,
for voltages
and
temperatures.
They went in
cleanly.
Haven’t
tackled stddev
yet (or the

overall

etc). There is
a very basic
‘bms status’

implemented.</div>

yes, .min
& .max are
the minimum
and maximum
readings seen
since last
battery
monitor reset.
The reset
should be
available as…<br
class="">
<ul class="">
<li class="">OvmsVehicle::ResetCellStats();</li>
<li class="">Command:
"vehicle bms
reset" …or
just "bms
reset" as we
also have
other vehicle
commands on
the root
level?<br
class="">
</li>
</ul>
On the Twizy I
do an auto
reset each
time the
vehicle is
turned on and
each time a
charge starts,
but that
behaviour
should be
controllable
by the vehicle
/ user.<br
class="">
<br class="">
<br class="">
There's
additionally
the overall {
.stddev, .avg
} on voltages
and
temperatures
of the pack.
These and the
cell level
statistics can
be calculated
by the
framework, so
the vehicle
simply needs
to provide the
readings. The
framework
needs to
provide a way
to reset the
readings
completion
bitset, i.e.<br
class="">
<ul class="">
<li class="">OvmsVehicle::RestartCellVoltages();</li>
<li class="">OvmsVehicle::RestartCellTemperatures();</li>
</ul>
…as sometimes
readings get
lost, and
adding new to
the previous
readings may
lead to an
inconsistent
view leading
to wrong
standard
deviation.<br
class="">
<br class="">
<br class="">
Speaking of
standard
deviation, the
framework
should also
provide
warnings and
alerts flags.
On the Twizy
it does so by
checking
deviation
thresholds,
and there's a
general stddev
warn &
alert
threshold to
detect overall
condition and
two alert
thresholds on
the cell
level, one for
normal stddev
and one for
stddev alert
mode. Warning
flags on the
cell level are
set when the
cell deviation
is above
stddev. On the
Twizy these
thresholds are
currently
fixed to…<br
class="">
<blockquote
class=""><tt

class="">
<tt class="">#define

…these are
good defaults
for the Twizy
43 Ah pouch
cells, but may
be too low for
an 18650 pack,
and will
especially not
fit cheap LFP
type cells. So
these should
be
configurable,
i.e.<br
class="">
<ul class="">
<li class="">vehicle
bms.dev.temp.alert [°C]</li>
<li class="">vehicle
bms.dev.voltage.alert [V]</li>
<li class="">vehicle

<li class="">vehicle
bms.stddev.voltage.watch [V]</li>
<li class="">vehicle
bms.stddev.voltage.alert [V]</li>
</ul>
I can
generalize the
Twizy code for
all of this.<br
class="">
<br class="">
<br class="">
The Twizy
battery
monitoring
command set
is:<br
class="">
<blockquote
class=""><tt
class="">OVMS#
xrt batt ?</tt><br
class="">
<tt class="">data-cell

</blockquote>
The "data"
commands
provide the
server
historical
records
output. The
other commands
originate from
the V2 and
have been
designed to
keep the
output within
the SMS msg
size limit.<br
class="">
<br class="">
"status" gives
an operative
overview of
the standard
and max
deviation
levels of
cells with
warning or
alert status.
"volt",
"vdev", "temp"
and "tdev"
show all
cells.<br
class="">
<br class="">
The Twizy
generates a
battery alert
notification
from the
"status"
output
whenever some
cell alert
flag is set.<br
class="">
<br class="">
<br class="">
The Twizy
server records
also originate
from the V2
limits, and
can now better
be changed to
vectors. I've
just finished
a virtual
dynamometer on
the Twizy,
sending a
vector metric
to the server
is just a
matter of…<br
class="">
<blockquote
class=""><tt
class="">std::string
msg =
"RT-ENG-MotTrqDrv,0,86400,";</tt><br
class="">
<tt class="">msg.append(m_mon.m_mot_torque_drv->AsString());</tt><br
class="">
<tt class="">MyNotify.NotifyString("data",
"xrt.pwr.mon",
msg.c_str());</tt><br
class="">
</blockquote>
Neat.<br
class="">
<br class="">
The Twizy
sends server
records once
per minute
during
drive/charge.
The server
update
frequency
should become
tunable as
well, as that
would be a lot
of additional
data volume on
large packs.<br
class="">
<br class="">
<br class="">
The Twizy
layout may be
either…<br
class="">
<ul
class="MailOutline">
<li class="">14
cell groups in
the pack</li>
<li class="">2
cell groups in
each module</li>
<li class="">7

Looking at the
discussion
with Michael
back in May,
we came to
some
conclusions
for this. I
was happy back
then with
using ‘cell’
rather than
‘module’ as
the naming,
because (a) we
are talking
about
cell/brick/module
level here,
not pack, and
(b) it is
shorter. It
seems that the
twizy has:

<div class="">Trying
to come up
with a
standard
representation
for this (so
everyone can
use a shared
library, and
share output
displays),
that works
across all
vehicles...
Assuming we
have
one-dimensional
arrays for
different
types of
measurement
(for voltage,
temperature,
etc),
measurements
are taken at
the group of
cells level
(with perhaps
different
groupings for
different
readings), and
aggregations/limits being automatically calculated, I think this has:</div>
<div class=""><br
class="">
</div>
<div class="">
<ol
class="MailOutline">
<li class="">v.b.c.voltage<br
class="">
<br class="">
Vector<float> metric type array of voltage measurements<br
class="">
<br class="">
</li>
<li class="">v.b.c.temp<br
class="">
<br class="">
Vector<float> metric type array of temperature measurements<br
class="">
<br class="">
</li>
<li class="">Aggregations
/ limits<br
class="">
<br class="">
We could have
v.b.c.voltage.min, v.b.c.voltage.max, v.b.c.voltage.maxdev,
v.b.c.temp.min,
v.b.c.temp.max, and v.b.c.temp.maxdev if we wanted to store these.
Presumably
they could be
automatically
calculated? I
am guessing
‘min’ is the
minimal value
seen, and
‘max’ the
maximum?<br
class="">
<br class="">
</li>
<li class="">Setting
as a batch<br
class="">
<br class="">
The way I’ve
implemented
the Model S is
to keep a
bitmap of
values set.
For example,
say we have 32
cell voltage
measurements.
Every time we
set a voltage
measurement,
we set the
appropriate
bit. When the
bitmap is
full, zero the
bitmap, then
set the metric
in bulk
(setting the
entire
vector). That
seems to work
well for Model
S at least.
The
aggregations/limits
would be
calculated
(and set) when
the batch is
ready. I
suggest
something
like:<br
class="">
<br class="">
</li>
<ul class="">
<li class="">OvmsVehicle::SetCellVoltage(int
index, float
value);</li>
<li class="">OvmsVehicle::SetCellTemperature(int
index, float
value);<br
class="">
<br class="">
</li>
</ul>
<li class="">Arrangement<br
class="">
<br class="">
My thinking is
that the count
of
measurements
available can
be defined
when the
module
initialises.
We can also
simply count
the size of
the vectors,
to know that.
The issue is
the
cell/brick/module/pack
arrangement;
How many
voltage or
temperature
measurements
per module,
how many
modules in the
pack, etc. I
think we need
to tell the
system (a) the
number of
readings
expected, (b)
the number of
readings per
module, and
(c) a hint to
say how many
readings to
show per row.
I suggest
something
like:<br
class="">
<br class="">
</li>
<ul class="">
<li class="">OvmsVehicle::SetCellArrangementVoltage(int
readings, int
readingspermodule, int readingsperrow)</li>
<li class="">OvmsVehicle::SetCellArrangementTemperature(int
readings, int
readingspermodule, int readingsperrow)<br class="">
<br class="">
</li>
</ul>
<li class="">Commands<br
class="">
<br class="">
Once the above
is defined we
can have a
‘vehicle bms
status’
command to
show the
status (like
the Tesla
Model S one
shown here,
albeit more
polished):</li>

Hi Mark.<br

<br class="">
Good idea with
a generic

standard

common EV
features!<br

<br class="">
Just a quick
note:<br
class="">
The Kia Soul
EV vehicle
module will be
able to
utilize these
metric-arrays.
However, on
the Soul, the
voltages are
for each
physical pair
of cells
connected in
parallel, and
the
temperatures
are for 6
battery
modules, and
for the
battery
cooling air
inlet. <br

<br class="">
So, for the
Kia Soul EV,
the name
“v.b.cell.temp”
would be
misleading, as
each measured
module
temperature is
representing
the state for
16 pairs of
cells.<br
class="">
<br class="">
Aside from
that, I am all
for mapping
the values in
these new
standardized
metric types.
Currently, the
temperature
average is
calculated and
mapped to a
metric, and
the 96 cell
voltages are
unmapped for
Kia Soul EV.<br

I?ve added
UnregisterCommand()
methods to
ovms_command.{h,
cpp}. I?ve
also updated
the
vehicle_teslamodels
code to
UnregisterCommand
in the
destructor. I
think that is
cleaner. The
unregistering
of CAN buses
already seems
to be working
properly,
config
parameters
should persist
(even without
vehicle module
loaded). I am
still
considering
the situation
with metrics
(but tend to
think that
they should
disappear when
the vehicle
module is
unloaded).<br
class="">
<br class="">
I?ve also
changed the
vehicle_teslamodels
code to use
single voltage
and temperate
metric arrays
(I think my
previous dual
voltage
temperature
arrangement
was
incorrect). I
think these
can now become
standard
metrics (one
for battery
voltage, and
another for
temperature).
How about
v.b.cell.voltage
and
v.b.cell.temp?
The
interpretation
of those
vectors (how
many modules
primarily -
with the
calculation of
voltages and
temperatures
per module
being
dependent on
the realtime
size of each
array) will
still be
vehicle
dependent, and
I guess the
vehicle module
can provide
hints to our
standard
component for
this. Perhaps
we can just
implement it
in vehicle.{h,
cpp}? I think
this standard
module can
deal with:<br
class="">
<br class="">
An interface
for specific
vehicle module
to specify the
number of
modules,
number of
voltage
measurements,
and number of
temperature
measurements
available.<br
class="">
Internal
storage of
cell voltages
and
temperatures.<br
class="">
Tracking of
when all
voltages and
temperatures
have been set,
and these
should be
written to
metrics (as a
transaction).<br
class="">
Standardised
command to
display on
terminal (like
?xts bms?).<br
class="">
Web interface
extensions
(including the
charting you
have, a
textual
display, etc).<br
class="">
<br class="">
I can handle
all of the
above, except
the web
interface.
What do you
think? Can
these be
standardised?
Certainly for
Tesla Roadster
and Tesla
Model S they
appear to be
able to be
unified under
one standard
framework.<br

1) yes, we're
approaching a
generic form
now. The chart
currently
displays
actual, min
& max
values from
the arrays,
and derives
the overall
average value.
It
automatically
adapts to the
number of
voltages and
temperatures
stored in the
arrays.<br
class="">
<br class="">
It still
lacks:<br
class="">
a) Displaying
max
deviations,
current
standard
deviation and
max standard
deviation
recorded.<br
class="">
b) Displaying
cell/module
warn &
alert status.
These are
currently set
metrics on the
Twizy, could
better be
generalized as
arrays as
well, i.e.
0=normal,
1=warn,
2=alert.<br
class="">
c) SOH /
capacity and
internal
resistance
should be
generally
available per
cell as well
(no data on
these yet on
the Twizy).<br
class="">
<br class="">
And as this
will visually
overload the
chart it will
need some
buttons to
show/hide the
parts.<br
class="">
<br class="">
A general
vehicle base
support for
these metrics
could
automatically
keep min &
max values,
calculate
deviations and
derive
warn/alert
status from
these. So
basically a
vehicle
adapter only
needs to
provide
voltages and
temperatures
(+ SOH and
internal
resistance as
available).
The reset
command then
can also
normally just
be a
generalized
version.<br
class="">
<br class="">
2) I should
add some basic
documentation
on this to the
developer
manual
(lacking
time). For the
RE tools I've
got an API to
inject
arbitrary data
into the
websocket
stream on my
todo list, so
live updates
can be
transported
without
polling.<br
class="">
<br class="">
4) Interesting
idea, similar
to a reverse
proxy. As the
channel will
be very slow
we will need
to reduce the
websocket
update
frequency,
make it
configurable
or maybe
auto-adapt to
the current
speed. Also,
the proxy
should cache
static assets
to speed up
first time
connects.<br
class="">
<br class="">
The v2
protocol using
RC4 encryption
is a bad base
for this.
What's the
current
encryption on
v3/MQTT?<br

Some
questions/comments:<br
class="">
<br class="">
I guess this
is fairly
generic.
Voltages and
temperatures,
with possibly
a different
number of
readings for
each. Model S
has two
temperatures,
but I guess we
can just treat
those as
interleaved.
Could it be
put into a
reusable
component? Or
could we have
standard
metrics for
this now
(battery
module
voltages and
temperatures)?
Maybe a single
component that
does all this
(functions to
set individual
voltages and
temperatures,
define the
layout for
display,
include web
interface for
chart and
table, etc)?<br
class="">
<br class="">
I really need
to look at
integration of
extensions to
the web
interface. See
how that is
done. For my
work on DBC
and RE tools,
it seems
easiest to
just create a
web interface
(rather than
messing around
with command
line).<br
class="">
<br class="">
Regarding the
registration
of commands
and metrics, I
am not sure if
that is done
correctly at
the moment. In
particular in
the case a
vehicle module
is loaded,
unloaded, then
loaded again.
It seems that
RegisterCommand doesn?t do it right, and the metric object creation
needs a guard
to make sure
the metric
doesn?t
already exist.
I will try to
tidy this up
in Model S
code, as a
reference,
before moving
on to
Roadster.<br
class="">
<br class="">
I really
haven?t used
the web
interface
much, as it is
not available
over cellular.
I was
wondering if
it could be
encapsulated
somehow within
the v2/v3
protocol, and
made available
via the
server?
Something like
<a
class="moz-txt-link-freetext"
href="https://api.openvehicles.com:8080/VEHICLEID"
moz-do-not-send="true">https://api.openvehicles.com:8080/VEHICLEID</a>
<a
class="moz-txt-link-rfc2396E"
href="https://api.openvehicles.com:8080/VEHICLEID"
moz-do-not-send="true"><https://api.openvehicles.com:8080/VEHICLEID></a>
tunnelled
through (with
authentication
at the server
level using
the normal web
server user
account).
Similarly for
SSH access.
These are both
simple tcp/ip
connections,
so presumably
could be
injected into
mongoose as
fake
connections.
One possible
approach would
be SOCKS, and
there is some
reference code
for LWIP <a
class="moz-txt-link-rfc2396E"
href="https://github.com/russdill/lwip/commit/dfeba616"
moz-do-not-send="true"><https://github.com/russdill/lwip/commit/dfeba616></a>.
Another is
TUN/TAP, again
with reference
code for LWIP
<a
class="moz-txt-link-rfc2396E"
href="https://github.com/russdill/lwip/commit/47ca42f8"
moz-do-not-send="true"><https://github.com/russdill/lwip/commit/47ca42f8></a>.
And then there
is the
standard PPP
(although that
would
technically
then be PPP
within tcp/ip
over PPP
within async
within GSM,
which is a bit
freaky).<br

I've prepared
a more or less
generalized
array version
of my Twizy
battery chart
(OvmsVehicleRenaultTwizy::WebBattMon) for you. Easier to collect the
data from
actual arrays
than separate
metrics.<br

?contains my
local ovms web
test/development folder. Unzip it into some local web server (needs to
be run via
http for
javascript),
then open the
folder from a
browser. You
should see an
OVMS web UI
lookalike.<br
class="">
<br class="">
Config ?
CellChart
loads
"cellchart.htm".
The blue
button
generates and
injects test
data. Should
look like
this:<br
class="">
<br class="">
<eoibkbnkbpofdlab.png><br class="">
<br class="">
Assuming
you'll add
some min/max
records as
well I left
that code
including the
reset button
in there. If
you can't
provide that
yet, you can
simply set min
& max =
act in the
get_xxx_data
functions.
Other than
that you
should
basically just
need to change
the metrics
names.<br
class="">
<br class="">
To generate
C/C++ syntax
from the file,
use the script
bin/mksrc:
"bin/mksrc
cellchart.htm
>cellchart.cpp". The chart init URL needs to be changed for the
production
environment
(see comment),
and the test
data generator
can be
removed. See
OvmsVehicleRenaultTwizy::WebBattMon for reference.<br class="">
<br class="">
Maybe I should
add that stuff
to the
repository as
well?<br

I've been

that only has
14 cells.<br

<br class="">
We discussed
this before, a
better
approach is
introducing a
new metric
class for
arrays. I have
just done that
for you,
please pull.<br

<br class="">
Usage example:<br
class="">
OvmsMetricVector<float>* vf = new
OvmsMetricVector<float>("test.volts", SM_STALE_MIN, Volts);<br
class="">
vf->SetElemValue(3, 1.23);<br class="">
vf->SetElemValue(17, 2.34);<br class="">
float
myvals[3] = {
5.5, 6.6, 7.7
};<br class="">
vf->SetElemValues(10, 3, myvals);<br class="">
With this data
set, you get:<br
class="">
OVMS# met lis
test<br
class="">
test.volts
0,0,0,1.23,0,0,0,0,0,0,5.5,6.6,7.7,0,0,0,0,2.34V<br
class="">
?and in the
web framework:<br
class="">
metrics["test.volts"]<br class="">
(18) [0, 0, 0,
1.23, 0, 0, 0,
0, 0, 0, 5.5,
6.6, 7.7, 0,
0, 0, 0, 2.34]<br

metrics["test.volts"][11]<br class="">
