Electrician refused to 'just add an outlet' for my EV charger, says it has to be its own dedicated circuit -- is he right or is this a pitch for a bigger job?

Got a quote to add a 240V outlet in my garage for a Level 2 charger, figured it'd be a quick job, maybe $300-400. The electrician came out, looked at my panel, and said he won't just tie into an existing circuit or add a basic outlet for this -- it has to be its own dedicated 50A circuit straight from the panel, GFCI protected, sized for a continuous load, or he's not comfortable putting his name on it. The quote tripled once he said that. I get being cautious, but is this actually a hard safety line for EV charging specifically, or do some electricians use 'EV charger = special circuit' as a way to upsell a bigger job than the customer asked for? Curious if anyone else has had the 'this needs to be its own circuit, no shortcuts' conversation and how it actually played out -- did the bigger job turn out to be genuinely necessary?

Dedicated circuit is not him being cautious, it's code. NEC 625.40 requires each outlet for EV charging to be supplied by an individual branch circuit with no other outlets. GFCI on the receptacle is required too (625.54). So you can't tie into an existing circuit, and he'd fail inspection if he did. The 50A part is a different story. Nothing says it has to be 50A. A 20A or 30A dedicated circuit is perfectly legal and is often all you need. What car and how many miles a day?

I had a dedicated 6-20 run for my EV6 for $300. Licensed guy, his own circuit, nothing fancy. It charges at about 3.8kW and that's plenty to fill up overnight on off-peak. You don't need 50A unless you drive a lot every day. Tripled to around $1000 for a 50A run isn't really a ripoff though, depending on how far the garage is from the panel.

Mine was $350 total on a 100 amp panel, with its own 50 amp breaker. The garage is on the other side of the wall from the panel so it was a short run. Distance makes a big difference in price because of the cost of 6 gauge copper. Ask him how many feet of wire he is figuring. The dedicated circuit is correct though. Every L2 charger I have seen says that in the install manual. Also have him do a load calculation on your panel before you go to 50 amps.
