To control a charging state of a battery.SOLUTION: A charging state control system 99 comprises: a power generator 40a that generates power and supplies the power to a load; a battery 32 that stores the power generated by the power generator 40a and supplies the stored power to the load; an ECU 33 that detects a charging state of the battery 32; and a control unit 91 that, when a remaining charge amount of the battery 32 detected by the ECU 33 is equal to or larger than a reservation threshold, discharges the power stored in the battery 32 to an external power supply 111 to control the charging state of the battery 32. As a result, the control unit 91 makes the battery 32 be charged by power supply from the power generator 40a and, when the remaining charge amount is equal to or larger than the reservation threshold, discharges the power stored in the battery 32 to the external power supply 111, which makes it possible to suppress progression of degradation of the battery 32 by keeping the remaining charge amount of the battery 32 about at or below the reservation threshold.SELECTED DRAWING: Figure 5
【課題】バッテリの充電状態を制御する。【解決手段】充電状態制御システム99は、発電して、負荷に電力を供給する発電装置40a、発電装置40aにより発電される電力を蓄えるとともに、蓄えた電力を負荷に供給するバッテリ32、バッテリ32の充電状態を検出するECU33、ECU33によるバッテリ32の残充電量の検出結果が保存閾値以上である場合にバッテリ32に蓄えられた電力を外部電源111に放電することで、バッテリ32の充電状態を制御する制御部91を備える。これによれば、制御部91により、バッテリ32が発電装置40aからの給電により充電され、その残充電量が保存閾値以上である場合にバッテリ32に蓄えられた電力を外部電源111に放電することで、バッテリ32の残充電量を保存閾値程度又は未満に維持してバッテリ32の劣化の進行を抑制することができる。【選択図】図5
