A method for monitoring the state of charge of a traction battery of a hybrid vehicle includes comparison of an actual state of charge with a state of charge limit value. If an initial actual state of charge lies above the state of charge limit value, waiting for a debounce time and output of a positive testing if the actual state of charge still lies above the state of charge limit value. If the initial actual state of charge lies below the state of charge limit value, continuous calculating of a model state of charge and output of a positive testing if the model state of charge reaches the state of charge limit value and does not fall short of it again for at least the debounce time.
