P3 Charging Index: Kia and Hyundai with top performance - Porsche Taycan charges with 325 kW
In the latest edition of the P3 Charging Index on the fast-charging capability of electric cars, the Korean manufacturer Kia continues to claim a top position. For long-distance qualities, it is also crucial how much time charging takes. The index, created by the internationally specialized electromobility consultancy P3 Group since 2019, provides a practical comparison value. It determines how much real range can be "refueled" in 20 minutes: 300 kilometers correspond to an index value of 1.0. The first vehicle to crack this mark was the Kia EV6 in 2022 with 309 kilometers (Index: 1.03). How outstanding this value was at the time is shown by the now published P3 Charging Index 2024: Despite the significantly increased number of competitors, the unchanged EV6 - a revised version with a stronger battery has been orderable since the end of October - was surpassed in its class only by the Ioniq 6 from the corporate sister Hyundai, which is based on the same platform (1.15 / 346 km). Overall, 22 current electric vehicles were evaluated for this year's P3 Charging Index, divided into two classes according to the gross list price: eleven models each in the mid-range (up to 62,500 euros) and in the premium class (over 62,500 euros).
Only the Porsche Taycan can do it faster
In the premium class, a Kia also belongs to the top 3: Behind the Porsche Taycan (1.28 / 383 km), with the highest value this year and the second-highest ever recorded at 325 kW, almost equal on the second and third place are Nio ET5 Touring (0.98 / 294 km) and the Kia EV9 (0.98 / 293 km), the only seven-seater among the tested models. The good performance of the brand’s 5.01-meter-long SUV flagship is "a remarkable result considering the dimensions of the vehicle," states the report on the P3 Charging Index 2024. And the charging curves show that the EV9 charges with consistently high power largely independent of the battery's state of charge (SoC). The report also attests this to the two leaders in the mid-range:
"The Kia EV6 and the Hyundai Ioniq 6 are characterized by consistently high charging power over a wide SoC window."
The Kia crossover, which secured another podium place for Kia as third in the overall ranking, left many renowned competitors behind in the mid-range, including Polestar 2 (0.93 / 278 km), Volkswagen ID.7 (0.86 / 257 km), Tesla Model 3 (0.84 / 253 km), BMW i4 eDrive40 (0.78 / 235 km) and Audi Q4 40 e-tron (0.62 / 187 km). In the premium class, the EV9 surpassed, among others, Mercedes-Benz EQS (0.92 / 275 km), BMW i5 eDrive40 (0.87 / 261 km) and Audi Q8 55 e-tron (0.71 / 213 km). Also outstanding: The winner of the P3CI Asia, the Lotus Emeya from the Geely group, was already able to be charged with more than 400kW by P3 during measurements for the P3 Charging Index Asia, which again underscores the ambitions of the Chinese automobile manufacturers.
Frequently, only 10-80 percent is specified, limited in significance
In the competitive comparison of various electric vehicles, the key figures of maximum charging power in kilowatts [kW] and the time for fast charging from 10% to 80% SoC are often simplified, the consulting firm explains. However, these two key figures only provide limited significance regarding the everyday suitability of fast charging capabilities of E-vehicles from the user's perspective. The P3 Charging Index was developed in 2019 by the P3 Group to make the real charging speed of electric vehicles comparable and easy to understand. The critical key figure for the user is rather the time needed to recharge real range in kilometers. As a result, the P3 Charging Index provides a comparison of the long-range capability of different electric vehicles. Using the consumption and charging curves of vehicles, the recharged kilometers in 10 and 20 minutes of charging time can be displayed, allowing a concrete comparison of the vehicles' fast charging behavior.
The charging window between 10% and 80% State-of-Charge (SoC) is considered, as this is where vehicles charge the fastest. Since the first edition in 2019, the P3 Charging Index has continuously evolved. The ideal value of the P3 Charging Index of 1.0 corresponds to an actually recharged range of 300km in a 20-minute interval: In the P3 Charging Index, only vehicles equipped with the European CCS (Combined Charging System – fast charging with Combo 2 plug) are considered. To ensure uniformity, practical relevance, and comparability of results, P3 refers to the consumption values of the ADAC Ecotest.
