All 2023 models will have preconditioned batteries. No model from 2022 has battery preconditioning. The hearing system in the 2022 model Battery is different. Different from battery precondition. I read this
here.
Battery preconditions via software or hardware were not made explicit by Hyundai. In my opinion, the battery preconditioning feature for 2023 will be a hardware update, while the battery preconditioning for the 2022 model may be a software feature. Although it might not be as effective as the 2023 model, it might still be an improvement.
