Charge/discharge determination apparatus, charge/discharge determination method and charge/discharge determination program

A charge/discharge determination method, comprising:

• receiving, by a communication unit comprising at least one processor and communicable with a battery and a plurality of charge/discharge instruction apparatuses, communication messages from the plurality of charge/discharge instruction apparatuses, wherein the communication messages comprises requests for access to the battery;
• determining whether each of the plurality of charge/discharge instruction apparatuses is permitted to access the battery based on accessibility information stored on a storage unit;
• determining a performance available to each of the plurality of charge/discharge instruction apparatuses in charging/discharging the battery based on charge/discharge information stored on the storage unit;
• and
• performing, by a control unit, a charge/discharge control simultaneously between each of the plurality of charge/discharge instruction apparatuses and the battery based on the accessibility information and the charge/discharge information.

A non-transitory computer-readable medium storing a charge/discharge determination program, the program causing a computer to execute operations, the operations comprising:

• receiving, by a communication unit comprising at least one processor and communicable with a battery and a plurality of charge/discharge instruction apparatuses, communication messages from the plurality of charge/discharge instruction apparatuses, wherein the communication messages comprises requests for access to the battery;
• determining whether each of the plurality of charge/discharge instruction apparatuses is permitted to access the battery based on accessibility information stored on a storage unit;
• determining a performance available to each of the plurality of charge/discharge instruction apparatuses in charging/discharging the battery based on charge/discharge information stored on the storage unit;
• and
• performing, by a control unit, a charge/discharge control simultaneously between each charge/discharge instruction apparatus and the battery based on the accessibility information and the charge/discharge information.
