Most homes that go to a level 2 charger that have either an ac or hot tub are gonna need this solution since you won’t want to upgrade your service and there’s really no need to anyways as the load management keeps your below the limit of the panel.

Yep very good advice here, the product name you’re looking for is a load miser. In all likelihood if it’s only a car charger with 30A @240v and you have no other major electrical loads (basically no AC, no hot tub, no baseboard heating) you will likely be ok without a lod miser. If you do have multiple of those then it’s time to get an electrician in and have a load calculation done on your home.
