Abstract: A storage battery unit includes: a battery module having a plurality of cells, and a module circuit connected to (i) an electric power line and (ii) a communication line; a unit circuit connected to (i) the module circuit by the electric power line and the communication line, and (ii) an electric power conversion device disposed externally; and a casing that accommodates the battery module and the unit circuit. The casing includes a top plate, a bottom plate, and a front plate respectively disposed on a top surface, bottom surface, and front surface of the storage battery unit. The top plate includes a first top plate portion that substantially covers an entirety of the top surface. The front plate includes a first lateral plate portion that substantially covers an entirety of the front surface, and a fixing component. The fixing component is disposed along the first top plate portion.

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 first connector for electrically connecting a first unit power terminal through a third unit power terminal to a power converter for performing conversion between a DC power and an AC power is mounted to a mounting port. In a status in which the first connector is being removed from the mounting port, it is impossible to mount the first connector to the mounting port while the first unit power terminal through the third unit power terminal are inputting and outputting a DC power, and it is possible to mount the first connector to the mounting port while the first unit power terminal through the third unit power terminal are not inputting and outputting a DC power.
