Many BMW i4 owners have encountered a frustrating and seemingly inexplicable phenomenon: the car charges normally at public AC charging stations, but fails to do so at home, despite the home hardware appearing to be working properly. This can lead to confusion and uncertainty, as people assume the problem isn't related to the home charging system, but this often isn't the case. People often assume the home charger isn't the problem, even though it's assumed to be working perfectly. The main reason for this discrepancy between home and public charging lies in the differences between public charging settings and components. Public stations often use standards and power settings that the car easily interprets, while the home system can present challenges, even if everything seems fine: cables, wallboxes, and programming configurations. The electrical system, especially if it's older and outdated, is likely the problem. To resolve the issue, the safest solution is to perform a thorough check: compare the charging cables, check the wallbox settings, and ensure they are compatible with the BMW i4's specifications. It's also important to verify that the car's charging settings are correct and that the home system supports the required current and power (perhaps calling a reputable electrician to perform system checks wouldn't be a bad idea). The system may be experiencing current leaks, thus reducing performance. In conclusion, before assuming the home charging system is faulty, it's advisable to perform a detailed comparison of the components and settings. Only then can you effectively identify and resolve the problem, ensuring reliable and stress-free charging at home.
