Output control device, output control method, and storage medium

An output control device of a lithium ion battery, the output control device comprising:

• an output control unit that controls an output of the lithium ion battery;
• a voltage measurement unit that measures a discharge voltage of the lithium ion battery;
• a current measurement unit that measures a discharge current of the lithium ion battery;
• and
• a computation unit that transmits a command to the output control unit,
• wherein the computation unit
• calculates a distribution of a current and/or a potential within the electrode thickness of the negative electrode of the lithium ion battery by using a heterogeneous reaction model in the thickness direction of the electrode, and compares the distribution with a preset upper limit current and/or lower limit potential in the negative electrode, and/or
• calculates a distribution of a current and/or a potential within the electrode thickness of the positive electrode of the lithium ion battery by using a heterogeneous reaction model in the thickness direction of the electrode, and compares the distribution with a preset upper limit current and/or upper limit potential in the positive electrode, and
• transmits a command to the output control unit on the basis of a result of the comparison, and
• the output control unit controls an output voltage and/or an output current of the lithium ion battery on the basis of the command.
