Abstract

PROVIDED IS AN INFORMATION PROCESSING DEVICE CAPABLE OF EASILY DETERMINING THE NUMBER OF TIMES OF CHARGE/ DISCHARGE OF EACH OF A PLURALITY OF SECONDARY BATTERY PACKS, THE INFORMATION PROCESSING DEVICE INCLUDING A CHARGE/DISCHARGE EXECUTION UNIT (21,22,23) HAVING THE FOLLOWING CONFIGURATION. THAT IS, THE CHARGE/ DISCHARGE EXECUTION UNIT (21,22,23) DETERMINES THE NUMBER OF TIMES OF CHARGE/DISCHARGE OF EACH PLURALITY OF SECONDARY BATTERY PACKS (11,12,13) BASED ON: THE NUMBER OF TIMES A FULLY-CHARGED STATE OF THE SECONDARY BATTERY PACK IS DETECTED WHEN THE CHARGE TO THE SECONDARY BATTERY PACK IS EXECUTED; THE NUMBER OF TIMES AN INTERMEDIATE STATE IN WHICH THE REMAINING CAPACITY OF THE SECONDARY BATTERY PACK BECOMES EQUAL TO A PREDETERMINED VALUE BETWEEN THE MAXIMUM REMAINING CAPACITY VALUE IN THE FULLY-CHARGED STATE AND A REMAINING CAPACITY OF ZERO IS DETECTED WHEN THE DISCHARGE FROM THE SECONDARY BATTERY PACK IS EXECUTED; AND THE NUMBER OF TIMES A REMAINING CAPACITY NEAR-ZERO STATE IN WHICH THE REMAINING CAPACITY OF THE SECONDARY BATTERY PACK BECOMES EQUAL TO A NEAR-ZERO VALUE CLOSER TO THE REMAINING CAPACITY OF ZERO THAN THE PREDETERMINED VALUE IS DETECTED WHEN THE DISCHARGE FROM THE SECONDARY BATTERY PACK IS EXECUTED.
