Abstract:
To prevent damage to a power storage system itself and an electric device connected to the power storage system due to the intrusion of lightning surges, and provide stable power supply in an event of a power outage.SOLUTION: A power storage system includes a determination circuit 3 that determines whether the lightning occurrence status is in a non-generated state, an initial stage, or a second stage, a system input unit 4, a power storage circuit 5 including a storage battery 22, and a switching device 6 that can switch to a first state in which power can be supplied from the system input unit 4 to the power storage battery 22 and a load 100, and a second state in which the system input unit 4, the power storage circuit 5, and a self-sustaining output unit 7 are cut off, and the power is supplied from the storage battery 5 to the load 100. A control circuit 8 controls the switching device 6 to be in the first state and starts charging the of power storage battery 22 when the lightning occurrence status is determined to be the initial stage, and controls the switching device to be in the second state and controls the power storage circuit 5 such that power is supplied from the power storage battery 22 to the load 100 when the lightning occurrence state is determined to be the second stage.SELECTED DRAWING: Figure 1
