Derek,<br>
<br>
thanks for the feedback. I understand you don't miss any vital
metrics.<br>
<br>
I prefer "gen" because it's the view of the vehicle as a power
generator, and because the abbreviation "v.g." is distinct, clear
& easily memorizable, with a clear advantage over "v.v." or any
"v.v2x." variant, and a nice coverage of the "grid" association on
"v.g." as well.<br>
<br>
"Generator" is also exactly the role of the vehicle in a V2X setup
(acting as a power generator). Regeneration or recuperation is
always a "re…" term.<br>
<br>
The voltages are both meant to be at the "grid" side, as we already
have the battery voltage as a separate metric, and as the charger
voltage is also defined to be that. See the comments:<br>
<br>
<font face="monospace"> OvmsMetricFloat*
ms_v_charge_voltage; // Momentary <b>charger supply</b>
voltage [V]
<br>
…<br>
OvmsMetricFloat* ms_v_gen_voltage; // Momentary <b>generator
output</b> voltage [V]
</font><br>
<br>
On the energy sums, I considered using some "output/input" or the
already defined "used/recd" scheme, but none of these is as clear as
"grid".<br>
<br>
I think "grid" nicely covers all normal V2X applications, also V2H,
as even a home without connection to the public power grid still has
it's own local in-house power grid. The only application where
"grid" is a bit off is if you connect only one device to the
generator. I think that's an edge case we don't need to take into
account.<br>
<br>
Regards,<br>

<div dir="auto">Hi Michael
<div dir="auto"><br>
</div>
<div dir="auto">Despite mentioning it some time ago I haven't
had time to progress anything around V2G, V2H. So good to see
you are. IMO using v.gen could be confusing as it is not
strictly operating as a generator, that is closer to motor
regeneration back into the pack. How about v2x instead which
covers both V2H and V2G applications? </div>
<div dir="auto"><br>
</div>
<div dir="auto">Is the voltage metric required as my
understanding is this will be the pack DC voltage? </div>
<div dir="auto"><br>
</div>
<div dir="auto">Given there is the possibility of V2H, so not
grid connected could you instead have v.v2x.kwh.output and
.input?</div>
