The BMW i4features scheduled charging, which allows you to plan charging at the best and most convenient times. This is typically done during times of day when energy rates are cheapest, such as at night. We've read many complaints about charging starting and then stopping after a few moments after plugging in the car. This happens because scheduled charging was set. It's as if the vehicle signals the charging system to activate, which then goes into standby until the exact time for restarting. If you want to avoid this, you should disable scheduled charging and proceed with the operation manually, starting direct charging.
