They might not burst into flames, today, but these technologies weren't invented because there was no risk.

> That would be 30% of your homes total power capacity just for changing EV

That's the thing - most people have a 8 to 12 hour window to fully charge their car(s) overnight and when you and your neighbors are using practically no energy. Worst case is there is no active management and there is just a new peak at midnight. Best case is that the electric company incentivizes you to not only charge at non-peak times, but also pays you to allow them to manage the charging times.

This technology is not science fiction - it already exists. I got a $250 rebate from my electric company to install a connected level 2 charger. It is not currently managed, but if there is some dystopian future where all of my neighbors aren't burning hydrocarbons, all have EVs, and somehow the infrastructure hasn't kept up, as long as my car is fully charged in the morning, I don't care if it happened from midnight to 2 AM or 4 AM to 6 AM.

But also...

> Most homes have 100 amp service

Most homes built decades ago, maybe. And to be clear, we're talking about US 120V system. I would be very surprised if any house built since...lets be generous...the 1980s doesn't have a 200A supply or couldn't easily be updated.

> GFCI and AFCI are great! But a home isn't going to burst into flames or explode without them. Which is why there are exemptions.

True, but not what you said. You said the changes are not safety related, but these are safety related.

Keep in mind 240v @ 30 amps = charging at 30 miles per hour or so. Common daily driving (12k miles a year) = 33 miles per day. Even throttling to 10 amps (which my charger supports), is 11 miles per hour or 110 miles per day if you charge for 10 hours.

Having had a 100 amp service, it was really not a big deal. Sure I'd normally charge at 11pm, when the AC wasn't running. But the home is using WAY less electricity than when I bought in 1994 when TVs consumed a ton of power, single paned windows insulated poorly, a fair number of 300 watt halogen bulbs, and tons of the 100 watt incandescents. Between LED lighting, a more efficient refrigerator, and a MUCH lower power flat panel TV our power use per day is less than it was in 1994, even with a EV.

100 amps @ 240v is a ton of power, and if you need to peak shave there's quite a bit of room between 240v@30 amps and 240v@10 amps which is plenty for most normal driving patterns.
