Hello, we are a manufacturer and have a very solid track record with not having any issues charging all the various models out there. In addition we recently modified our design to have a wider tolerance.
Even with this design we have a report of customer pulling up on a Hyundai Ionniq & a Kia EV6 and having charging issues.
Does anyone know what could be the cause? Why these vehicles specifically?
Thank you!
Ioniq 5 had at least two different problems charging L2 at 48A, overheating of the J-1772 input port and overheating of the ICCU (the I5 AC charger under the rear passenger seat). There have been numerous service notes and software updates. On the connector side, they have service check the connections and replace the connector and internal car cable as needed. On the software side, at least in the first update, they automatically limit the current down within the car ICCU control presumably as needed based on temperature rise. EV6 had similar problems.
This is probably not the best forum. Probably best to review threads (there are many) at the main IONIQ 5 and EV6 forums before posting there:
https://www.ioniqforum.com/https://www.kiaevforums.com/These problems were kind of ironic, because with the 800V architecture, I5 and EV6 are among the fastest BEVs to charge at DC fast charge stations. However, at home, they proved to be "delicate" at best above L2 32A. I traded my I5 in, in part because of the constant ICCU problems. Driving a Cadillac LYRIQ now, which charges flawlessly at 48A, some LYRIQs are L2 80A capable too!
