Battery Degradation: Maximizing Battery Life & Performance
Battery degradation refers to the gradual decline in the ability of a battery to store and deliver energy. This inevitable process can result in reduced energy capacity, range, power, and overall efficiency of your device or vehicle. The battery pack in an all-electric vehicle is designed to last the lifetime of the vehicle.

Hyundai Ioniq 5 battery preconditioning: is it worth the upgrade?
For this charging session, the Ioniq 5 didn''t preheat the battery. Exactly why this happened remains unclear: either the battery was still warm enough from the fast charging process in Lauenau, or the battery level was too low at the scheduled arrival at the EnBW fast charger. The Hyundai system only works up to a certain charge level.
