Some cars by Tesla, report that home charging via a power outlet is fine, and DC charging also works properly, but issues are encountered with charging with a wallbox. The Tesla charging cableshould be in perfect working order and it is unlikely that this is the cause of the problem. There could be several causes to consider, starting with the compatibility of the wallbox. Is it compatible with your Tesla and the appropriate charging specifications (connection type, maximum power, supported protocols, sockets, voltage type)? If so, make sure the wallbox is correctly configured, including parameters such as voltage, maximum current, charging mode, and any safety restrictions. Check that the connections are correct and that there are no wiring issues, such as loose connections or damaged wires. If everything is OK, are you sure you've updated the charging system's firmware to the latest version? Updates can fix bugs or improve compatibility, especially since some issues can arise from incompatibilities in the communication protocols between the Tesla and the wallbox, especially if the charger uses advanced communication features. There may be current limitations set on the wallbox or protections preventing proper charging. Check that they are configured correctly and compatible with your car's needs. One of the "old methods" might work: resetting the wallbox. If nothing changes, you'll need to look at the settings, but the best advice is to try charging at another wallbox to isolate the problem and verify the results. If the problem persists, it may be helpful to have the electrical system checked by a qualified professional to ensure everything is up to code and functioning properly.
