POWER STORAGE SYSTEM

摘要

[Problem] In a power storage device with multiple power storage components connected in parallel, the activation of a current blocking device in a power storage component causes changes in the current flowing in a power storage component in which the current blocking device is not activated. [Solution] This power storage system includes: a power storage device that includes parallelly connected multiple power storage components; and a controller for controlling charging/discharging of the power storage device. Each power storage component has a current blocking device for interrupting a current path inside the power storage component. The controller controls charging/discharging of the power storage device with reference to the values of currents that flow in power storage components with uninterrupted current paths. The values of the currents flowing in the power storage components with uninterrupted current paths change according to an increase in the number of current blocking devices that are in an open state.
