I thought, Tesla used to charge $2k+ for their high power wall chargers. Is Tesla giving L2 charger for free now? It is listed on the site for $500 currently.
There is a thread here on home charging. Seems people got melted outlets using their NEMA outlets, besides vlockign the dryer outlet.
And no, you can't just pluf in 3.8KW circuit into a 15A outlet. You will have to add a dedicated 40A/80A circuit breaker. If that triggers a panel upgrade, that's additional.
If the total goes over the total panel capacity (100A most common in households) and you have to go to 200A, that's extra and gets expensive due to permitting, planning change with utility. etc.
- Tesla includes a UMC with every car which is a L2 connector.
- Yeah... sometimes a wire comes loose in a 14-50... same things happens on occasion with a HPWC or any other electric circuit. It's rare but it happens. Most people use a 14-50 daily with no problem.
- Yes... you absolutely can upgrade a 110v 15A circuit to a 240v 20A circuit for 3.8kW usually with the same wire. I should know... I co-own a licensed electric company.
- Most people don't 'need' >3.8kW to charge their EV. Plenty of people get by with just L1... although as I've stated upgrading to 16A L2 is cheap, easy and well worth it.
