Edmunds is a very reputable website that has been synthesizing and analyzing the US car market for over 50 years. This November, they published results of a study on actual electric vehicle charging speeds that were remarkable.
Using its own formula combined with actual measurements, Edmunds analyzed the charging speeds of 43 electric vehicle models widely available in the U.S. market over the past few years to find the fastest names.
According to actual data, the car model with the fastest charging speed is Hyundai Ioniq 6 Limited RWD, with a charging rate of 1,397 km/h. Another name is Kia EV6 RWD which runs at 1,238 km/h charging. Completing the top 3 is the 2-wheel drive AWD version of the Hyundai Ioniq 6 at 1,230 km/h.
In fact, the top 10 fastest charging car models have 6 names from the Hyundai – Kia group. Apart from the top 3 mentioned, they also have the Kia EV6 GT Line (5th, 1,091 km charge/h), Hyundai Ioniq 5 AWD (6th, 1,083 km charge/h) and the Genesis Electrified G80 (8th, 853 km charge/h) . ,
The remaining 4 names in the top 10 come from 3 different carmakers. In the highest ranking, the Porsche Taycan 4S is in 4th place with a charging speed of 1,110 km/h, another Taycan version, the GTS, is in 9th place with a charging speed of 940 km/h. The Mercedes-Benz EQS 450+ in 7th (954 km charge/h) and the Tesla Model 3 in 10th (912 km charge/h) completed the top group.
Edmunds’ test measures the charging efficiency of an electric vehicle by dividing the charging capacity (kW) by the power consumption rate (kWh/100 miles) and then multiplying by 100 to get the final result of miles/1 hour charging . This unit of measurement in the data above has been changed to km/1 hour of charging to make it more familiar to Vietnamese users.
Another factor considered in Edmunds’ testing was that charging speeds were measured when the battery was in the optimal range of 10 to 80%. This is the optimal charging range of an electric battery, as charging above/below the above marks takes much longer, and causes the life cycle of the electric battery to decrease rapidly (or in other words, it is easier to degrade).
Although the results measured by Edmunds are actual results and not as announced by the companies, users should take this only as a reference measure and not take it too seriously. This is because when they charge in public, there are very few charging stations that support fast charging at the maximum level and give the above results.
