Remote cooling has a cost
Hycan's app lets owners cool the cabin before walking out to the car, a feature that gets heavy use in UAE summers. Each remote session wakes the car's control units, and the 12V battery carries that wake-up until the high-voltage system takes over. Several sessions a day, in a car parked in full sun, add real wear. If the app starts reporting the car as unreachable, the auxiliary battery is a likely suspect.
