Many Tesla users and owners note that AC charging via the public grid works without any apparent issues, while a home wallbox can experience difficulties, sometimes becoming unreliable or interrupting the flow of power. This discrepancy is particularly frustrating, as the home setup should provide greater predictability and convenience and be the simplest. The causes of these issues can be found in a variety of factors: faulty or poorly connected cables, incorrect wallbox settings, or programmed behaviors that interfere with the charging process, as well as system issues. Before blaming the vehicle or the home's electrical system, it's essential to perform a detailed comparison of the various components. Checking the charging cables, ensuring they are intact and properly connected, and verifying the wallbox settings can often resolve the issue. It's also helpful to analyze the wallbox's behavior with scheduled charging: charging time slots or energy optimization modes may interfere with normal operation. Try deleting all configured schedules and attempting a manual charge via your wallbox and his Tesla charging cable. While charging via the public grid may seem more reliable, it's still important to understand the causes of issues with home charging using a wallbox. A careful comparison of components and settings allows you to identify and resolve issues, thus ensuring safer and more predictable home charging. But even more important and sensible is checking your home's electrical system to determine the maximum power allowed by the meter and the power set on the wallbox. If there's a discrepancy, charging is obviously more complex or even impossible.
