Autel 50 amp MaxiCharge for Tesla Y

Thanks for the correction. I seriously doubt my attic will ever come close to that.

There are calculation tables in code for temperature derating. It’s a factor, not an absolute.

Still works great at 48 amps L2. Only issue is J1772 is needed for this charger. Not really a big deal.

No disadvantage to the Tesla vehicle or battery when charging using Level 2 (240V) at the maximum supported 48 amp rate of the Tesla Model Y versus lower amperage. (Some data exists that charging at 40 amps might be slightly more efficient.) 48 amp charging may require the Tesla vehicle to perform some additional cooling of the charging components, possibly the battery. The Tesla Model Y will automatically cool (or warm) these components as required.

The industry standard Level 1 (120V) / Level 2 (240V) in the US and Canada is the J1772 connector. Tesla vehicles sold in the US and Canada use Tesla's connector. To charge a Tesla vehicle using a J1772 charging connector you simply use the provided Tesla SAE J1772 charging adapter. This adapter is included with every new Tesla vehicle sold in the US, Canada. Additional Tesla J1772 adapters are available from Tesla's online store at Tesla.com for ($50 US). In this way you can keep a spare adapter or have one at home and one in the vehicle at all times.

To add my experience to your mention of 40amp efficiency. I experimented with my Tesla app, using my L2 Tesla Wall Charger (2nd generation I'm pretty sure). I used settings from 32 amp to 48, and compared the charging efficiency reported by TeslaFi. I landed on 40 amp as most efficient, averaging 96%. 48 amps was next best. None of the lower amp settings gave efficiency that was higher - actually notably less so.
