Abstract
According to one embodiment, a storage battery device includes a battery unit, a charging unit, a terminal, and a first circuit breaking unit. The battery unit includes a lithium ion battery and is connectable in parallel to other storage battery device that charges an external lithium ion battery. The charging unit is supplied with electric power from an external electric power source and charges the battery unit. The terminal is connectable to a wire connecting the other storage battery device with the battery unit. The first circuit breaking unit is connected between the battery unit and the terminal, and blocks an electric current flowing from the terminal to the battery unit.
