OBD-II was implemented to monitor emissions, but EVs don't have tailpipes.
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.::OBD-II was implemented to monitor emissions, but EVs don't have tailpipes.
My i3 has an OBD-II port, and it's not the only EV that has one. Bimmercode can change A LOT of vehicle settings through the port, and software like ABRP can use it to read out the battery level and route you to the next charger when needed.
I'm surprised more people don't realize that OBDII is basically "car USB" at this point... Info can go both ways and a lot more info comes out of the car than it did in 95 when it was introduced AND we're able to reprogram cars using it!
