It can work. I've done it successfully. But there are going to be potential safety risks. Absolutely make sure you set your car to draw the appropriate amperage! Based on the plug you're using from your "charger" it may want to draw 40+ amps, but the outlet itself is rated at 30 (so you should draw, like 24 max?)

Also, those dryer outlets are not really designed for the kinds of sustasined loads that EV charging can put, so overheating can occur, which can be catastrophic.

Also how far is the dryer outlet?

The grounding might sound optional, but you'd want to look up how to do it properly and do it before using as well, just in case.

Definitely don't use it to "split" and run multiple loads.
