A secondary battery system includes a secondary battery, an abnormality detecting unit OC which detects whether the secondary battery has become abnormal, and a signal generating circuit which outputs a signal to an externally connected device based on detection information of the abnormality detecting unit OC. The signal generating circuit includes a circuit element that can be held at least in a first state and in a second state. The signal generating circuit is configured to change an output state of a signal to the externally connected device based on whether the circuit element is in the first state or in the second state. The signal generating circuit is configured to switch the circuit element from the first state to the second state when the abnormality detecting unit OC has detected the abnormal state, and not to return the circuit element to the first state.
