During overnight charging, some Tesla interrupt or slow down charging, disconcerting the owner who wakes up to find the battery level significantly lower than expected. This anomaly can be caused by a variety of reasons and conditions. First, it's important to note that Tesla has a system that automatically manages charging power. This means that if any problems arise during the charging session, the charging process can be halted. This is done for safety reasons. Another likely cause is related to smart charging: if set (usually at 80%), the vehicle does not exceed this threshold, turning off the charger. If there is programming, this could interfere with the set limit and therefore create problems for the proper charging process. The system could also go into protection mode, especially if there are other draws. Remember that it's very important to have a meter capable of supporting the required current. If this doesn't happen, the circuit breaker or differential switch trips and blocks the flow of electricity. Furthermore, especially at night, the simultaneous operation of other AC (220-volt) appliances could create imbalances and fluctuations, slowing down or even stopping the car's charging. In apartment buildings, this situation often occurs precisely because multiple people are simultaneously drawing power for washing machines, dryers, dishwashers, small electric heaters, or air conditioners. Here's another consideration. During the coldest period, recharging is physiologically slower. So it's important to consider this variable. Try deleting the scheduled charging settings and proceeding by testing a manual direct charge. Finally, it could also be the faulty Tesla charging cable that will need to be replaced.
