With some Tesla we encounter a scheduled charging timing issue. Specifically,Tesla charging sometimes begins before the scheduled time. The owner expects the car to wait until the scheduled time to begin charging, but the wallbox or the car itself seems to start drawing energy early. This could result in excessive energy and cost expenditure, as charging typically waits for the cheapest time of day, such as during the night. To troubleshoot and find a solution, it may be logical to check the app's (and therefore vehicle's) scheduling and that of the wallbox or charger. To avoid inconveniences and software conflicts, it's always best to manage charging with a single schedule, choosing either the car or the wallbox, and avoiding simultaneous scheduling.
