  • Hyundai and Kia make the fastest-charging electric cars on the market. 
  • Some cars can add over 800 miles of range in an hour, while others might be less than half that.
  • Edmunds' test is one of the first to show head-to-head charging speed based on real-world data. 

One of customers' biggest anxieties about electric vehicles is how long it'll take to get to a full charge.

And while it's relatively rare that a full charge overnight at home won't get you to where you're going, there are road trips when charging won't be nearly as fast as getting gas. And not all cars are created equal in that regard.

Charging speed can be affected by many factors, like the weather, battery temperature, crowding of the charging station, and internal settings designed to prevent you from charging too fast — which can damage the battery in the long run.

Still, there are chemical and engineering differences from car to car and battery to battery that affect charging speed, and are worth considering when making a purchase.

There isn't a standard industry measure for charging speed. So to test EVs head-to-head, the experts at Edmunds used data from the firm P3 that monitored electricity use while an EV was connected to a level-3 fast charger. The dataset also included power-request communication between the vehicle and charging station to track each battery's capacity.

Combined with Edmund's own data on electricity-per-mile on different vehicles, the results give one us one of our first looks at charging speeds across automakers and models.

Here's the list of top 10 fastest-charging EVs, as reported by Edmunds:

Even with a range less than competitors like Lucid and Tesla, the Mercedes Benz EQS has plenty of range to get where you need to go, our reviewer found, and can recharge among the quickest of models out there.
