Just read this article from Hyundai which could be read that battery conditioning is a new feature not available in existing Ioniq 5s. I'm living in hope that this is already in the full battery system in the EV6 (which wasn't in the Ioniq 5 that was rushed to market to get Korean subsidies)., otherwise all EV6 and Ioniq 5 models sold last/this year will be a different model missing an important feature.
