Home Charger-ChatGpt Suggestion

[kibucs]

Hi-

I'm on the waitlist for the R2 so starting to plan for the home charger. First time EV owner btw.
Setup: Home charger to be installed in the garage. Main electrical panel is in the basement the opposite side of the house as the garage. There's a sub panel in the basement that is underneath the garage. I'm clueless when it comes to electricity so ran it by ChatGpt to see what my options are. I have not contacted an electrician yet, just doing some research in advance.

This is ChatGpt's recommendation. Does this sound like a reasonable solution? Any suggestions are welcome.
-------------------------
Existing 50A feeder from main panel → subpanel → Tesla Wall Connector

The Tesla Remote Meter monitors the current being used by the subpanel. The charger then automatically adjusts the R2's charging rate based on how much capacity is available.

For example:

• Dryer off, washer off → R2 charges faster
• Dryer turns on → R2 charging automatically slows
• Other loads increase → charging slows further
• Loads turn off → R2 charging automatically speeds back up

You do nothing manually. The charger continuously adjusts itself to keep the monitored panel within the configured limit.

What you would buy

• 1 Tesla Universal Wall Connector — the same one you found
• 1 Tesla Remote Meter — $210, specifically to enable Dynamic Power Management
• Electrical installation and commissioning

For your house, this is potentially a particularly good solution. Your nearby 50A subpanel has a large 30A dryer circuit, but the dryer is intermittent. Dynamic Power Management lets the EV use more of the available capacity when the dryer is off rather than permanently limiting the charger to a low setting. Tesla specifically positions the feature as a way to maximize charging speed while avoiding electrical upgrades.

In my opinion, try to install a dedicated 48amp wall charger. And if that’s too expensive or prohibitive logistically, then work backwards to a cheaper or able solution

That's what AI came up with after assessing my current house config ie working backwards to an able solution. The main issue is that the main panel is the opposite side of the house in the basement, which is finished, therefore several thousands just to run the wiring from the main panel to the garage.

If limited by the 30A breaker on the dryer, then your charging will be max 5.7kW (80% * 30A * 240V). I guess it’s doable, but it’s on the slower side of charging at home.

Many suitable L2 chargers, Chargepoint, Rivian, Tesla, Etc.....At this point shop by price.

AI is assuming the limitation on your home is the size of your main panel. That may be true, but I wouldn't trust AI (or you) to make that assessment without a lot of detailed information. There is a process to do this calculation that involves a lot of information AI probably doesn't have.

However, that 50A nearby sub-panel is probably the right answer regardless.

Load sharing tech is one good option.

I'll throw out one other opportunity. You could free up most (or all?) of that 50A subpanel if you're open to switching to a heat-pump washer/dryer combo. Those only need a regular 120V/15A circuit. It would free up that big 240V/30A circuit your dryer is currently using.
