There's nothing worse than believing your car is charged when it's not. Actually, let's explain. Sometimes Tesla appears to have finished charging, but in reality it is continuing because it is not yet complete. This situation creates a misunderstanding: you think you can immediately set off on your trip with a full charge, but in reality, you still have to wait a while for the charge to finish. You could even set off again, knowing full well that you don't have 100% range. But where does this confusing idea come from? The charging status light changes color, or the car changes "status" to energy saving mode, and everything suggests charging is complete. The colored indicator light, like the car's status, are indicators, but they may not always convey the correct message. It's best to check the car's display or smartphone screen, using the dedicated app, to get the correct information on the car's actual charging percentage, so you can accurately calculate the time needed to complete the session.
