Craig,

I strictly vote against re-interpretation of the SOC metric. Where metrics have clear semantics we should not make them dependent on some context.

A battery is not a fuel tank, and vehicles may have both. "v.b." is the namespace "vehicle battery" and shall not be populated with non-battery metrics.

That's what I meant by adding technology specific metrics: if the vehicle has a fuel tank, additional standard metrics describing that fuel tank shall be present.

Fuel tank specific metrics might e.g. get the namespace "v.ft.", ICE engine specific metrics might get "v.ice.", fuel cell metrics "v.fc.", rocket thruster metrics "v.rt." … you get the idea.

Make a proposition for the metrics sets you need. Try to define them as generalized as possible.

That will probably include duplicates of some metrics, like the ranges & consumption. That's necessary to be able to describe a hybrid, and some units among those will also need to be different (e.g. consumption in litres / m³ per km).

Regards,
Michael

Thank you for considering my thoughts.

I believe it is a good idea to use a v.tech variable and not using gas or gazoline. That gives OVMS enough flexibility and is also a (little) statement.

I'm also looking forward to rocket propulsion add ons :-))

How about adding an array or set metric like "v.ext" or "v.tech", for
defined technology codes. A tag present in the metric means the
additional metrics, commands & configs for that technology are available.



My goal is to make it possible for the app to depict soc with something
other than a battery graphic when the energy source is not a battery.
How about v.tech with "battery" and "other" as the initial two possible
values?
