  "textContent": "An obj ect of the present invention is to provide a battery controller capable of performing charge and discharge control of a assembly battery so that a state of charge of each battery cell forming a battery does not deviate from a predetermined usage range. The present invention relates to a battery controller which controls a assembly battery 110 formed by connecting a plurality of battery cells 111. The battery controller calculates an actual average charge state C AVE which is an average charge state of the plurality of battery cells 111 on the basis of each state C of charge of the plurality of battery cells 111, calculates an average charge state upper limit value C AVEH and an average charge state lower limit value C AVEL taken by the actual average charge state of the plurality of battery cells 111 in a preset usage range on the basis of each state C of charge and the actual average charge state C AVE of the plurality of battery cells 111, calculates an average charge state ratio S indicating a position of the actual average charge state C AVE between the average charge state upper limit value C AVEH and the average charge state lower limit value C AVEL , and calculates a assembly battery charge state C PACK of the assembly battery 110 on the basis of the actual average charge state C AVE , the average charge state upper limit value C AVEH , the average charge state lower limit value C AVEL , and the average charge state ratio S.",
