Why don’t EVs have standard diagnostic ports—and when will that change? | OBD-II was implemented to monitor emissions, but EVs don't have tailpipes. (arstechnica.com)

What would they diagnose?

Combustion Engine? Don't have one. Transmission? Don't have one. Emission Control System? Don't have emissions. Spark Plugs? Nope. Fuel System? No. Exhaust? No. Alternator? No. Battery charger? you can see that on the dashboard. Starter motor? Nope. Battery Status? Also on the dashboard. Vehicle speed... on the dash. Engine idle... no. Air Flow Sensor? No air flow. Intake Manifold Pressure... no intake. Throttle position... only really relevant if you have a clutch or torque converter which EVs don't have (you would notice, very quickly, if the throttle position detected pressing the pedal when you're not pressing it in an EV...

That's the list of standard ODB-II diagnostics. Some cars do more than that, but those are the ones they have to do. And none of them are relevant.

This is also a important example of how much less crap there is in a electric vs ICE vehicle.

Yes the battery materials are mined (so are many other things) but the sheer subtraction of these various mechanisms from a electric vehicle greatly reduces the environment impact not to mention a great reduction in fluids required.

Dealers hate this one hack as the service requirements are fairly low too.

There are also idiots claiming we should ban electric vehicles because they charge on an unclean grid

I actually saw a petition for this is my country's local government website

This is like closing a shop to prevent robbers.

Surely the solution is to make the grid they charge off of sustainable then????

Too expensive. It's easier to just ban electricity, and go back to the good ol' days of natural gas powered appliances.
