I'm learning about OBDII, and I'm wondering whether it is valid on EV's too.
According to Wikipedia's PIDs article, the Service 01 PID 51 (or Fuel Type) has a value
8 that means that the fuel type of the vehicle is Electric.
However, it seems that the corresponding regulation (ISO-15031) is only about "emission relevant" information? From what I can deduce, OBD-II is a general reference for all type of vehicles and ISO-15031 is only a subset of OBD-II that regulates PIDs on emissions. Is that correct? I also read on the same Wikipedia page that there are 10 services, but it seems that only 3 of them are documented (1,2,9). I'd like to know whether there is an official document on the OBD-II standard.
My question is as follows: Is the word "emission-related" (that one can found in various services) only an historical trace from the birth of OBD-II standard? (To what extent does the standard apply to EV's?)
