The Hyundai Ioniq 5 and Kia EV6 are born electric cars offering some of the best performance, efficiency and charging power available on the market today. However, with a black point: the impossibility, so far, of charging them on Tesla V3 Superchargers.
This is a recurring question that we have been asked for several months in the comments or on social networks, and a little more so as the major holiday trips approach: why the attempts to recharge the EV6 and Ioniq 5 ( and soon 6), both based on Kia’s and Hyundai’s E-GMP platform, systematically result in failure on Tesla V3 Superchargers open to other brands? There is even a topic on our forum which today counts 12 pages!
This is all the more frustrating as the two models are both reliable and efficient on other charging networks, whether Ionity, Electra or Fastned, allowing to go from 10 to 80% charge in 18 minutes, a time that it is now possible to reach in all temperatures thanks to the addition of the battery pre-conditioning that has just been done.
The Tesla Model 3 and Model Y would charge slower than before
Another particularly annoying point: the complete radio silence on the side of the Korean brands since we do not know officially where the problem comes from. One thing is certain though: there is a communication problem between the charging station and the vehicle.
What is causing this misunderstanding? Two hypotheses according to feedback: the locking of the connector itself on the car side or, more profoundly, an incompatibility with the unique architecture on the market of the e-GMP platform. Working differently from other 800V systems like the one found on the Porsche Taycan and Audi e-tron GT, the latter actually boosts the voltage from 400 to 800V via the motor and inverter, a way of doing things that could not be tolerated by the Tesla terminals which would then go into default.
Many conditional therefore in the absence of official communication, the representatives of the Korean manufacturers validating the existence of the problem, but having no comment to make. However, we can count on Tesla, in its desire to open up to other brands, to tackle the problem head on: the American, without providing further details, determined the origin of the problem and provided an update. software to its Superchargers that it is currently rolling out. However, if this development will allow the Ioniq 5 and EV6 to perform refills successfully, they will be at “limited power”.
