It may happen that by connecting your Tesla to the home electrical network through a normal 220 Volt socket, the car can easily recharge. It may be a little slower than other methods, but you can still get a full charge. When connecting to a home wallbox, however, charging doesn't start, or there are problems that interrupt the session. First: check your Tesla charging cable. It's correct? Why? The main reason is that home wallboxes operate at higher power levels than traditional household meters can generally handle. In fact, before installing a wallbox, it's a good idea to understand the characteristics of your meter and electrical system. It's common practice to request an increase in the maximum sustainable power to ensure the current is supported as effectively as possible. If you have the possibility, you can reduce the charging power of the wallbox, choosing the lower value than the maximum 7.4 kW. Most often, the cause of failure to charge using a wallbox at home is due to incompatibility between it and the electrical power supply. Alternatively, the cause could be found in comparing the configurations used for charging via the home plug and the wallbox. Different settings are usually required. If possible, testing a new charge with a home wallbox by connecting another vehicle could be a further test to verify the proper functioning of the charging platform.
