To enable Smart Charging by Energy, begin by ensuring that you have added your tariff and car information to your account. Once this step is completed, navigate to the Overview screen on your charging interface. Scroll down until you find the Smart Schedule option, and click on it to access the Smart Charging settings. Within these settings, you will have the option to set Smart Charging by Energy. Choose your desired charging target and specify the time by which you want your vehicle to be fully charged. After configuring your preferences, save the settings. The same Smart Charging schedule, based on your specified targets, will be automatically recreated each time you plug in your vehicle for charging, optimising both cost efficiency and convenience.
