For example if your electric utility offers time of use discounts

Completely false, that's built into the car. I have multiple TOU rates and both the Rivian and Tesla can handle them with a dumb EVSE.

or special rates for EV charging they'll need you to have a smarter EVSE.

Also not true here, you can get the EV special rate without a smart EVSE.

The only things I've ever seen that have data requirements are the programs where the utility can delay/stop charging, and the programs where they specifically want your charging data. However, they don't require a smart EVSE as long as your car has data they can get access to (most EVs). In our area, they support a lot of cars, but only one EVSE; Emporia.

It 100% depends on your electric utility. In MA my electric company requires you enroll both the EVSE and your car to get the discounts and rebates.

• They manage it through a third party called ev.energy https://www.ev.energy/en-us/drivers/integrations

You'll note that the Rivian R1 is on the list of supported EVs, but their EVSE isn't.

You're right that pure time of use billing is fine with just the car so that was a misleading statement from me. I should have been more precise.

Depends on the utility company. In MD and specifically BGE, you have to have either a certain brand of vehicle or have one of 3 EVSE that they approved to qualify for the TOU rates for your EV.

Another fun fact here…our EV TOU rate ends up costing more than the regular TOU rate for most households. Same for my brother in southern CA.
