Charging an electric vehicle costs three times as much at a public charging site in West Virginia than in Nebraska, according to data gathered by Stable, a software developer for EV charging.

Why it matters: The gap suggests companies are still figuring out what to charge drivers when topping up their EVs.

Big picture: West Virginia, Connecticut, Arizona, Massachusetts and Kentucky have the most expensive charging stations, according to Stable's survey of about 9,000 fast-charging stations in January.

  • Prices there ranged from $0.52 to $0.54 per kilowatt-hour.
  • Nebraska, Mississippi, Iowa, North Dakota, and Kansas were the cheapest, with prices spanning $0.17 to $0.31.

All told, a driver would spend about $11.05 in Nebraska and $35.10 in West Virginia to fill a Chevy Bolt, the most popular non-Tesla EV in the U.S. last year.

What's happening: Charging networks such as Electrify America, EVgo, and ChargePoint consider a host of factors in setting their charging price — not least the local electricity rate.

  • Cheap electricity in America's Midwest, for example, may explain the discounts in Nebraska, Iowa, North Dakota and Kansas, which aren't exactly hotbeds of EV adoption.

Yes, but: The big gap in prices suggests something is amiss, Stable argues. The older a charging location, for example, the closer it hews to $0.40 to $0.50.

  • Gasoline prices of course also differ across state lines, but not as greatly as EV charging rates.

"Prices are probably set incorrectly and don't reflect underlying supply-demand," Stable tells Axios.

  • "There is still a lot of price herding in the industry with players by and large setting their prices based on what other nearby chargers have set their prices at."

What we're watching: More networks in the past six months have started adopting Tesla's variable pricing model, which accounts for the site location, time of day, and amount of power a station is delivering.
