POWER AND CHARGING MANAGEMENT APPARATUS

To allow power supply from a charger to an electric automobile continuously even when sufficient power is not charged to a storage battery.SOLUTION: A power and charging management apparatus includes a storage battery, a charger, and a power management device. The power and charging management apparatus receives first measurement data indicating the value of power that is supplied from a low-voltage power reception facility to a power load, calculates first suppliable power data indicating the value of power that can be supplied from the low-voltage power reception facility on the basis of a rated output of the low-voltage power reception facility and the first measurement data, receives a first integrated value of power charged to the storage battery and a second integrated value of power discharged from the storage battery, and calculates, as second measurement data, the value of power that is stored into the storage battery from the first and second integrated values.SELECTED DRAWING: Figure 1 【課題】蓄電池に十分な電力が充電されていなくても、充電器から電気自動車への給電を継続することができるようにする。【解決手段】蓄電池と、充電器と、電力管理装置と、を有する電力・充電管理装置であって、前記電力管理装置は、前記低圧受電設備から電力負荷に供給される電力の値を示す第１の計量データを受信し、前記低圧受電設備の定格出力と、前記第１の計量データとに基づいて、前記低圧受電設備から供給可能な電力の値を示す第１の供給可能電力データを算出し、前記蓄電池に充電された電力の第１の積算値と前記蓄電池から放電された電力の第２の積算値とを受信し、前記第１及び第２の積算値から前記蓄電池に蓄電される電力の値を第２の計量データとして算出する。【選択図】図１
