There has been plenty of local news about minor fires caused by EV charging in recent years. Usually neither the house nor the car burn to the ground, so won't make national news.

Typical cause seems to be old, worn-out installations or improperly done installations.

Perhaps 999/1000 outlets being able to function safely at rated longterm maximum draw (when there is no obviously visible damage) used to be an acceptable ratio. Doing anything close to maximum draw for long periods and unsupervised was less common.

With EV-charging becoming more common the old standard is no longer good enough. There is too little margin for error and too high likelihood of a situation where error leads to damage.
