Abstract: An electricity storage system includes a main body and a portable unit. The main body includes a casing, a first storage battery module that stores power, and a first terminal unit to supply the power. The portable unit includes a second terminal unit and a second storage battery module, and is attachable to and detachable from the first terminal unit. The second terminal unit is electrically connectable to the first terminal unit and receives the power supplied from the main body. The second storage battery module has a storage capacity less than the first storage battery module. The portable unit further includes a charging controller, upon determination of power supply from the system power supply has been stopped, the charging controller controls a charging rate for the second storage battery module to be charged at least one of a normal mode and a high-speed mode.

Abstract: A method performed by an information terminal is provided. Profile information of an electrical device connected to a storage battery pack is received from the storage battery pack. The profile information includes device identification information of the electrical device and an item of state information indicating a state of the electrical device. A value of the item of state information of the electrical device is received from the storage battery pack. When a first instruction that causes the item of state information and the value of the item of state information to be displayed is received, a first display screen is displayed on the display of the information terminal. The first display screen depicts the item of state information and the value of the item of state information by using the received profile information and the received value of the item of state information.
