Evaluation method and device according to purposes of reusable battery

A apparatus for an evaluation of a reusable battery, the apparatus comprising:

• a communicator;
• and
• a processor configured to connect to the communicator,
• wherein the processor is configured to perform:
• a process of obtaining state of health (SOH) information, state of balance (SOB) information, and state of power (SOP) information of the reusable battery;
• a process of extracting evaluation parameters from the SOH information, the SOB information, and the SOP information;
• a process of inputting the evaluation parameters into each of a plurality of evaluation models that differently set a weight for each of the evaluation parameters according to usages of the reusable battery;
• a process of calculating evaluation results corresponding to the usages of the reusable battery from the evaluation parameters using the plurality of evaluation models;
• and
• a process of automatically classifying at least one usage of the reusable battery based on the evaluation results,
• wherein the SOB information includes information on correlation between the SOC and the SOB according to a change in the SOC of the reusable battery, and
• wherein the evaluation parameter includes information on:
• SOC boundary values corresponding to boundary between a plurality of levels set for a SOB value of the reusable battery;
• correlation between the SOB and a rate of discharge (ROD) according to a change in the ROD of the reusable battery;
• and
• an upper limit of tolerant output for each operating time of the reusable battery.
