Some cars by Tesla only start charging after the car "wakes up," meaning after the user opens the app, approaches the vehicle, or performs another activation action (such as unlocking the doors, but not limited to). This behavior can be annoying because it prevents immediate and automatic charging, impacting convenience and efficiency. The causes of this inconvenience can be found in the settings and charging profiles. Tesla, like other electric vehicles, has sleep or power saving modes to optimize battery usage. In some configurations, functions such as remote charging or vehicle wake up may be limited or require manual action by the user. To resolve this issue, it's advisable to update the software and firmware, adjust the charging settings, and possibly configure moderate power saving modes. Communication between the app, the on board system, and the charger can be affected by security or power saving settings. You may need to configure your vehicle to start charging automatically without having to wake up every time, but this requires updated software. Teslaregularly releases updates to improve functionality and resolve issues. It's a good idea to ensure your vehicle is running the latest firmware, as some issues of this nature may have been resolved with subsequent updates. We recommend comparing the results of direct charging with scheduled charging and checking whether the behavior during sleep mode fits this pattern. It may be helpful to set up scheduled charging (for example, at specific times) and check whether it starts automatically without intervention. Check the sleep mode and remote communication settings and see if the "abnormal" behavior occurs only under certain conditions or with specific configurations.
