To protect a connector while reducing cost.SOLUTION: A discharge control device 10 of a battery 3 supplies power to each of an inverter 4 connected to an electric motor 2 for driving a vehicle 1 and a distribution part 5 for distributing power to an auxiliary machine mounted on the vehicle 1 through a connector includes an acquisition part 11, a calculation part 12, and a control part 13. The acquisition part 11 acquires a battery current value Ib corresponding to a current emitted from the battery 3, and an inverter current value Ic corresponding to the current flowing in the inverter 4. The calculation part 12 calculates a distribution current value Id corresponding to the current flowing in the distribution part 5 from the battery 3, on the basis of the battery current value Ib and the inverter current value Ic acquired by the acquisition part 11. The control part 13 controls a discharge amount of the battery 3 so that the inverter current value Ic acquired by the acquisition part 11 and the distribution current value Id calculated by the calculation part 12 satisfy a current specification allowed in the connector.SELECTED DRAWING: Figure 1

    【課題】コストを抑えつつコネクタを保護する。【解決手段】車両1を駆動する電動モータ2に接続されたインバータ4と車両1に搭載された補機に電力を分配する分配部5とのそれぞれにコネクタを介して電力を供給するバッテリ3の放電制御装置10は、取得部11と算出部12と制御部13とを含む。取得部11は、バッテリ3から放出される電流に対応するバッテリ電流値Ib及びインバータ4を流れる電流に対応するインバータ電流値Icを取得する。算出部12は、取得部11で取得されたバッテリ電流値Ib及びインバータ電流値Icに基づき、バッテリ3から分配部5へ流れる電流に対応する分配電流値Idを算出する。制御部13は、取得部11で取得されたインバータ電流値Icと算出部12で算出された分配電流値Idとが、コネクタにおいて許容される電流仕様を満たすように、バッテリ3の放電量を制御する。【選択図】図1
