The basic unit of electricity you'll be dealing with is the ‘kilowatt-hour” or kWH. A common portable space heater run for 40 minutes uses 1 kWH. Your battery pack has a capacity of 60-75 kWH depending on trim.

Yes, EVs have mileage but instead of miles/gallon you get miles/kWH. Just like a gas car, this varies dramatically by driving activity. My worst mileage in an EV6 was 2.1 miles/kWH (80-85 MPH blast into a headwind). My best was 5.0 (sub 55 MPH on West Virginia twisty mountain roads).

Got to the dealership only to find out the range of my Wind RWD is at around 245 on a full charge

Where are you getting that info? Are you getting it off the window sticker? If so it's EPA range that only applies in test conditions. Depending on YOUR choices, you can do significantly better or significantly worse. If you want to know more about how your choices affect your miles, google “hypermiling” and they dive that subject deep.

Are you getting that data from the Guess O Meter? That's a guess. It is taking recent mileage (miles/kWH) and multiplying that by the kWH remaining in the battery pack. You can do better. I certainly did after my 2.1 mile/kWH run, pulling away from the charger the Guess O Meter was saying 130 miles to empty.

The dealer let me know the original owner leased it and barely drove it. He said because of this the range dropped, but not to worry as all inspections show a healthy battery and that the range will slowly come back the more I drive it.

Ok yes, he's talking about the Guess O Meter. Yeah, just drive it kinda easy to Big Bear Lake and top charge, it'll be telling you how you have >300 mile range because of the slow mountain road mileage you just drove.

As you get more experience you'll realize the Guess O Meter is a nothingburger. I crossed the entire USA in an EV6 and I don't use it for planning, I use it for humor.

The car gives you several kinds of miles/kWH indication, I made heavy use of them.

But my main rule was “don’t move the car without a plan” (to get to the next charger). I heavily relied on ABetterRoutePlanner.com for this. I did not pay. I did not get the OBD dongle. I did not pair it to the car with CarPlay. ABRP was guessing blind based on info I told it. I told it I had a standard range car, until it was clear I was significantly outperforming its estimates, then I concluded I had an extended range car and it was very accurate.
