Abstract
Description
図1は、本開示を適用した実施形態に係る電力分配システムのブロック回路図である。図1に示す電力分配システムは、不図示の車両に搭載され、第1DC/DCコンバータ1_1及び第1DC/DCコンバータ1_1と並列に設けられた第1バッテリ7_1からメイン負荷6_1に電力を供給し、第2DC/DCコンバータ1_2及び第2DC/DCコンバータ1_2と並列に設けられた第2バッテリ7_2からバックアップ負荷6_2に電力を供給するものである。不図示の車両は、例えば、電気自動車、プラグインハイブリッドカー(PHEV;Plug−in Hybrid Electric Vehicle)又はハイブリッド電気自動車(HEV;Hybrid Electric Vehicle)等である。
次に、具体的な制御例について図6を用いて説明する。図6は、本開示を適用した実施形態に係る電力分配システムの制御例を説明するフローチャートである。ステップS11において、ECU3は、ナビゲーションシステム5から走行ルート情報を取得したか否かを判定する。ECU3は、ナビゲーションシステム5から走行ルート情報を取得したと判定する場合(ステップS11;Y)、ステップS12の処理に移行する。ECU3は、ナビゲーションシステム5から走行ルート情報を取得していないと判定する場合(ステップS11;N)、ステップS11の処理を繰り返す。
以上の説明から、本実施形態において、ナビゲーションシステム5の走行ルート情報から導出される想定出力容量に応じて、第2DC/DCコンバータ1_2の出力電圧が制御される。想定出力容量は、不図示の車両の現地点Sから目標地点Gまでの移動距離の途中までの途中地点a1,a2におけるバックアップ負荷6_2のうちの駆動負荷の使用電力を供給可能な容量であって、第2バッテリ7_2の満充電状態よりも低い閾値バッテリ容量未満に設定されるものである。よって、第2バッテリ7_2の充電状態は、第2バッテリ7_2の満充電状態よりも低い。したがって、第2バッテリ7_2の劣化を抑制することができる。
