Abstract

The storage battery system according to one embodiment of the present disclosure comprises: a storage battery module having a storage battery and a storage battery monitoring circuit; a power terminal connected to the storage battery module; a control circuit; and a power supply circuit capable of performing power supply to the control circuit and the storage battery monitoring circuit. The power supply circuit is selectively operable in any of the following modes: a first operation mode which performs power supply to the control circuit and the storage battery monitoring circuit; a second operation mode which, when charging operation is not performed on the storage battery over a predetermined time and a charging level is reduced to a first predetermined value, performs power supply to the control circuit and intermittently performs power supply to the storage battery monitoring circuit; and a third operation mode which, when the charging operation is not performed on the storage battery and the charging level is reduced to a second predetermined value lower than the first predetermined value, stops the power supply to the control circuit and the storage battery monitoring circuit.
