Arizona's electric vehicle charging stations have the nation's second highest average price, per data gathered by Stable Auto, an EV charger software developer.
The big picture: It costs an average of 53 cents per kilowatt-hour (kWh) to charge an EV at a public charging station in Arizona.
Context: A typical EV with 300 miles of range usually takes about 75-100 kWh to go from empty to full.
The big picture: Charging an electric vehicle costs three times as much at a public charging site in Arizona than in Nebraska — a gap that suggests EV charging companies are still figuring out how to price a top-off.
What's happening: Charging networks such as Electrify America, EVgo, and ChargePoint consider various factors in setting their charging price — not least the local electricity rate.
For example, cheap electricity in the Midwest may explain the discounts in Nebraska.
Yes, but: The big gap in prices suggests something is amiss, Stable argues.
"Prices are probably set incorrectly and don't reflect underlying supply-demand," Stable CEO Rohan Puri 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."
