A power storage device includes a power storage unit including one or a plurality of cells, a first controller for performing control relating to the power storage unit, a first power line for supplying a first power to be output from the power storage unit to a load, a second power line for supplying a second power smaller than the first power to a second controller included in an external device, and a communication line used by the first and second controllers to communicate with each other.

Power storage device, power storage system, and electric vehicle

Disclosed herein is a control apparatus, including: a discrimination section configured to discriminate a plurality of battery units which are to share and output electric power required by a load; and a control section configured to carry out discharge control for the battery units in response to a situation of each of batteries which the battery units individually have.

Control apparatus to control discharge from battery units

A control system includes a first device configured to receive a first voltage, and convert the first voltage to a second voltage that varies according to a variation of the received first voltage. The control system also includes a second device configured to receive the second voltage and to change a charging rate of an energy storage device according to a variation of the received second voltage.

Control system including a device configured to change a charging rate of a battery, control device, and control method of the same

Disclosed herein is a control system, including: a first apparatus configured to adjust an output voltage thereof so that the output voltage may be included in a range determined in advance in response to a variation of an input voltage thereto from an electric power generation section; and a second apparatus configured to change a charge rate into a battery in response to the variation of the input voltage supplied from the first apparatus, wherein when a state in which the output voltage from the first apparatus is near to a lower limit thereof continues for a period longer than a period of time set in advance, one of two or more lower limits prepared in advance is selected as the value of the lower limit in accordance with to which one of sections set in advance input current from the electric power generation section belongs.
