A vehicle-use storage battery system includes a storage battery, a main circuit, a circuit breaker, a storage battery management unit, a first determiner, and a second determiner. The main circuit is electrically connected to the storage battery. The circuit breaker is disposed between the storage battery and the main circuit to make or break the electrical connection therebetween. The storage battery management unit manages an operating state of the storage battery. The first determiner determines whether to break the electrical connection between the storage battery and the main circuit by means of the circuit breaker. The second determiner determines, on the basis of at least one of operating states of the storage battery management unit, the first determiner, and the circuit breaker, whether to break the electrical connection between the storage battery and the main circuit by means of the circuit breaker.
