Can Level 2 Charge Rate be set in the car?

[Its.Jacey]

Quick question for anyone who has come across something like this, so can Level 2 charge rate be set in the car, or does it all depend on the charger?
In my setup, the wall unit can deliver more than the car usually pulls, and I'm wondering if there's a way to cap the rate from inside the vehicle itself, I want in a way that will really consider battery longevity and managing load as priority when I've got other things running in the garage.
I know that some EVs seem to have this buried in settings, others just take whatever the EVSE gives. I've got a 48A capable charger installed by the way, but I don't always want to pull full power, especially during peak hours. I checked the settings briefly but didn't see anything obvious about limiting the amperage from the car side but I'm kinda hoping I just missed it

GM only allows you to set a lower limit for Level 1 charging, which is 8A or 12A. Level 2 charging depends on the EVSE, which is a bummer since companies like Tesla have figured that out. At home, I usualy charge at 20A since it's easier on the batt, but I can bump it up to 48A if I need a quick charge. I drive about 25 miles a day, so Level 1 might be fine for me too

Have you thought about changing the output on your EVSE?

My concern is most EVs don't let you limit charging amps from the car itself, it usually depends on the charger settings. Without that, you might have to manually adjust your wall unit to protect your battery and manage load

That's a great question! Generally, most electric vehicles don't allow you to set the Level 2 charging rate directly from the car,it's typically the charger that manages that. GM has a bit of a limitation here, as you can only modify the Level 1 amps from within the vehicle. It seems like adjusting your EVSE output could be the way to go for keeping your battery healthy and balancing the load during busy times. Have you looked into whether your charger has options for scheduling or current adjustments?

Yeah, most cars won't let you tweak Level 2 charging rates from the cabin I mean it's usually all up to the EVSE. The best bet is to dial it back on your wall unit if you want to baby the battery or avoid peak load. LOL. Not really 100 percent sure tho.

No, there is no Level 2 charge rate level setting. However, you can delay the charge by using the "Charge Later" setting on the charge menu before you plug your level 2 charger in. That way it will delay starting the charge and be ready when the time you set rolls around. I use it frequently and usually it is ready within 1% of the charge level that I set it at when the complete charge by time I set it at. The reason I use it is because I don't want the Lyriq sitting charged to the level I set it at for a long time before I use it, especially in the hot weather. It is supposed to lengthen the battery life. I spent a lot for this car, and I want it to last at least 10 years.
