Where I believe all OEMs need to place far more effort into. Wayne Gerdes – CleanMPG – Nov. 15, 2023 Everyone knows charging an electric vehicle isn't the same as filling up a fuel tank. It takes much longer and charging times differ considerably from vehicle to vehicle, varying weather conditions, and the individual chargers design and physical condition. Historically, there has been no industry standard for measuring charging speeds — auto manufacturers have been able to pick and choose charging data to highlight the best attributes of their vehicles without scrutiny. The Edmunds EV Charging Test establishes their own standard, based on their testing and empirical data. It's the first independent measure of how quickly a car can add range to its battery at a fast charger. I would not say the first or the best, but the results are interesting, easy to disseminate, and useful. According to Edmunds, the fastest charging vehicle in the U.S. in terms of adding miles of range over a given std. hour is the 361-mile rated range, Hyundai Ioniq 6 in RWD trim. 2023 Hyundai Ioniq 6 In detail, the Ioniq 6 RWD is the fastest-charging EV Edmunds has tested to date with 100 miles of range being added in an average time of just 6 mins and 54 secs, the equivalent of 868 miles per charging hour. This is based on the average charge rate when charging from 10 to 80%. No other EV Edmunds tested was able to break the 7-minute barrier albeit the range added was based on Edmund’s testing. 2022 Hyundai Ioniq 5 Charging Profile Not the same vehicle but the exact same battery, inverter, and charging hardware beneath the sheet metal charged from 10 to 80% in 18-min and 55-sec. The IONIQ 6 RWD model and its 77.4-kWh battery pack outpaced the test’s second-place finisher by an impressive 99 miles/charging hour. The IONIQ 6 AWD model finished in third place with 764 miles/charging hour, adding 100 miles in an average time of 7 mins. and 51 secs. The entire list including a sortable database table with other interesting attributes can be found at the Edmunds EV Charging Test page.
