Abstract
A plurality of storage battery modules include storage battery control devices that can mutually communicate with each other and obtain a demand for electric power in a predetermined consumer in which the plurality of storage battery modules are provided. The storage battery control devices mutually transmit and receive charging/discharging electric power of the storage batteries and control charging/discharging of the plurality of storage battery modules, respectively, on the basis of the demand for electric power in the predetermined consumer.
Claims9
A storage battery control device comprising:
- a charging/discharging control unit configured to acquire a demand for electric power in a consumer to which a storage battery is provided;
- and
- a communication unit configured to acquire a charging/discharging electric power amount of another storage battery provided to the consumer, wherein
- the charging/discharging control unit is configured to control charging/discharging of the storage battery based on the charging/discharging electric power amount of the another storage battery and the demand for electric power in the consumer,
- wherein the charging/discharging control unit is configured to manage a threshold value of an electric power amount of the storage battery to determine whether the charging/discharging control unit is to allow charging or discharging of the storage battery,
- wherein:
- when the threshold value is greater than the demand for electric power, the charging/discharging control unit is configured to allow charging of the storage battery and prohibit discharging;
- and
- when the threshold value is less than or equal to the demand for electric power, the charging/discharging control unit is configured to prohibit charging of the storage battery and allow discharging.
A method for controlling charging/discharging of a storage battery, the method comprising:
- acquiring, via a charging/discharging control unit, a demand for electric power in a consumer to which a storage battery is provided;
- acquiring, via a communication unit, a charging/discharging electric power amount of another storage batter provided to the consumer;
- controlling, via the charging/discharging control unit, charging/discharging of the storage battery, based on the charging/discharging electric power amount of the another storage battery and the demand for electric power in the consumer;
- managing, via the charging/discharging control unit, a threshold value of an electric power amount of the storage battery to determine whether the charging/discharging control unit is to allow charging or discharging of the storage battery;
- when the threshold value is greater than the demand for electric power, via the charging/discharging control unit, allowing charging of the storage battery and prohibiting discharging;
- and
- when the threshold value is less than or equal to the demand for electric power, via the charging/discharging control unit, prohibiting charging of the storage battery and allowing discharging.
