The power conversion system includes an inverter circuit. The inverter circuit performs a grid-connected operation and an independent operation. When performing the independent operation, the inverter circuit may output, via a terminal, AC power converted to a load disconnected from a power grid. When the inverter circuit performs the independent operation, a control unit controls, when operating in a first mode, the power conversion system in a first time range such that an AC voltage is applied to the terminal, and controls, when operating in a second mode, the power conversion system in a second time range different from the first time range. The second mode includes control of stopping an operation of having the AC voltage applied to the terminal.

Control system, power system, control method, and program

A rechargeable battery system includes: a first battery pack; and a second battery pack in a daisy chain connection with the first battery pack to form a communication path, the second battery pack consuming a larger power for communication than a power consumed in the first battery pack for communication. A power consumed in the second battery pack for an additional process other than communication is smaller than power consumed in the first battery pack for the additional process.

Rechargeable battery system and method of controlling power consumption

A rechargeable battery management unit (controller) controls a plurality of battery packs. A communication path connects the rechargeable battery management unit and the plurality of battery packs in a daisy chain for packet communication and representing a ring topology. The rechargeable battery management unit sends a fixed-length packet divided into segments so as to flow in one direction on the management data communication path, the number of segments being equal to or more than the number of battery packs. Each of the plurality of battery packs stores data related to the battery pack in a segment assigned to the battery pack in the fixed-length packet received from a battery pack preceding in the management data communication path and sends the fixed-length packet to a succeeding battery pack.
