図1は、本発明の第1実施形態に係わる電力供給システムの概略を示す図である。
(第2実施形態)
続いて、本発明の第2実施形態に係わる電力供給システムについて説明する。
(1)充電コンセントからの充電電力のうちその日利用されなかった充電電力を算出するために、(充電コンセントからの充電電力)−(走行時に使用した電力)を算出して記憶する。
(2)回生電力のうち過充電にあたる部分を算出するために、(想定走行距離から導き出される回生電力)−(次の日必要となる電力)を算出して記憶する。
(3)回生電力のうち次の日必要となる電力を算出して記憶する。
(4)リフレッシュ放電電力を算出するために、(満充電されてからの期間×予め定めた劣化係数)を算出して記憶する。
(5)エンジンを始動して発電した電力を算出するために、(建物12の負荷のうち、予め設定された停電時稼働させる電気機器の必要電力量に合わせた発電量)を記憶する。なお、環境のため基本的には必要最小限の発電で制御されるが、停電が長期化する場合には、コントローラ28の操作によるモード変更等により、建物12内の電気機器16へ供給した上で、自動車22の車両用蓄電池24を充電可能なレベルの発電を行うようにしてもよい。
