• Charging with a standard 220 Volt household socket (slow charging or "AC charging"): a standard household power socket is used. This slow charging is ideal for keeping costs low, for those who charge overnight, and for those who are not in a hurry.
• Home charging wallbox (fixed charging station): Installing a wallbox at home requires the use of a BMW i4 Type 2 charging cable. Charging is slightly faster because the wallbox generates and delivers electricity with a power of up to 7.4 kW. This solution also allows you to plan charging according to a schedule and provides safer charging.

When setting power and capacity configurations, the latter depends on the home electrical system (home wallboxes range from 3.7 kW to 7.4 kW), and it may therefore be necessary to upgrade the system by increasing the meter's maximum sustainable power. With an "old" or unsuitable meter, charging may be problematic because the power set for the wallbox is not supported by the meter and the home electrical system. Increasing the meter load, requiring an upgrade, will make charging faster. The charging session may also be affected by various safety devices such as differential circuit breakers and circuit breakers. These could cut off the power and prevent your BMW i4 from charging. Home charging configurations must take into account the different methods and infrastructures that allow you to conveniently charge your electric car at home, adapting to your charging speed needs and the characteristics of your home electrical system. To understand the problem, it's helpful to proceed through trial and error to determine which configurations work and which don't, or perform less well. Resetting the scheduled charging, for example, could benefit the system by avoiding conflicts between different settings. The advice is to proceed step by step: first try charging with simpler setups to verify the vehicle's charging behavior.
