Most typical use is electrical stove/range. For EV charges, you'd want to go with 6 guage if you can (and your panel allows it).

Highly recommended to over size wiring for EV charging.
Masejoer
And if not hard-wired, a quality 14-50R if going for 40A continuous - not the $10 things sold at the big box stores. $50+ Hubbell HBL9450A or equivalent for reliability.

All kinds of things. An EVSE (electric vehicle charger) is a typical use. 40A circuit, good for 32A continuous. Typically do not need 8/3 though, 8/2 (no neutral) would be sufficient.

These days you need 40A continuous.

In the average home, you'll find larger gauge wire serving the following:

Electric Stove
Electric Clothes Dryer
Central Heat With Electric Coils
Tankless or Tank Water Heater
Larger Central Air Condensers

Any of these will be plainly marked with amperage requirements for circuit sizing, which easily translates to wire and breaker size. All of the above typically have a dedicated circuit and breaker.

Really you should do 4-gauge so you can do 50-amp continuous (48 amp charger).
I used 6AWG wire for 60A circuit... you can do this as long as you're using 75C or 90C-rated wire, such as THW, THWN or THHN.

Useful for solar if you want to run low voltage/high amperage.

Lot of people run high voltage to save on copper.

That's some dangerous advise. First, residential breakers are generally rated at 75c. You cannot use the 90c column unless all components in the circuit are rated for 90c.

Second, that wire is only good for 65A noncontinuous loads at 75c. If you want 60A continuous as you would need for an EV, you'd need something rated for 75A, or 4AWG THHN. Your wire is undersized.
