New Test Ranks EVs' Charge Times

Edmunds unveiled an electric-vehicle fast-charging test it says shows how quickly an EV model charges.

Charging efficiency is one of a mix of factors prospective EV adopters consider when contemplating a switch from gas-powered models. Gassing up a car takes a fairly predictable amount of time, depending on whether one has to wait to pull up to a pump, but charging speed can vary widely, depending on the model. A recent S&P Global Mobility study found charge speed ranked second only to high price among consumers' reasons for opting out of EV purchases.

Edmunds claims its EV Charging Test independently determines the amount of time it takes an individual model to charge via a fast-charger. It says the evaluation combines Level 3 charging measurements – Level 3 being the fastest charging type – with data from its own efficiency test to arrive at “a new industry standard for electric vehicle charging speeds.”

The company said it tested more than 40 EV models in the inaugural round to arrive at a ranking based on charging speed, putting the Hyundai Ioniq 6 sedan at the top with an average speed of 868 miles per charging hour, or the equivalent of 100 miles of charge in just under seven minutes. At the bottom of the list is the Chevrolet Bolt EUV at 172 miles per charging hour.

Along with the Ioniq 6, top charging performers are the Kia EV6 crossover sports-utility vehicle and the Porsche Taycan sports car, Edmunds said, pointing out that optimum charging efficiency isn’t reserved to luxury models.

Edmunds says the test can hold vehicle makers accountable about charging speeds.

"For too long, automakers have been able to pick and choose, without scrutiny, charging data in order to highlight the best attributes of their vehicles," said Editor-in-Chief Alistair Weaver, who in a press release called the test “an industry benchmark that allows car shoppers to compare charging speeds based on real-world testing and empirical data."

Federal prosecutors are reportedly investigating whether Tesla exaggerated its models’ range between charges after an August Reuters report said the U.S. EV market leader overstated ranges in advertisements and vehicle range meters.

The Edmunds test’s miles per charging hour indicates average charging speeds when charging from 10% to 80%, also expressed as the average time needed to achieve 100 miles of charge. Also included in results are average charging power, peak charging power, charging losses and consumption.
