[Ovmsdev] Toyota bZ4X and Subaru Solterra

[Mark Webb-Johnson]

Solterra,

Michael’s advice is good.

If it is just two names for essentially the same vehicle, I think you can refer to vehicle_voltampera (which implemented the Chevy Volt and Open Ampera vehicle support). These were essentially the same vehicle platform, but with minor bodywork differences and labelling.

If the two vehicles share the same platform (such as BMS, battery, etc) but are otherwise very different, then I suggest you implement a vehicle_<platform> for that platform, and derive two classes from that in the same /src/ directory (one for each vehicle type). That will allow you to put all common support code in the base platform, but have each vehicle type customisable (and individually selectable).

Looking at images of the cars, it seems they are closest to the Volt Ampera situation. Perhaps BZSS?

Regards, Mark.
