Abstract
Description
図1は、実施の形態1による制御装置100の構成を示すブロック図である。蓄電装置10は、1つまたは複数の電池から構成されるものである。変換器20は、蓄電装置10より出力する電圧を変換して昇圧または降圧して電力を負荷30に供給する、あるいは、蓄電装置10に入力する電圧を変換して昇圧または降圧するものである。制御装置100は、検出部1、インピーダンス計算部2、リプル電流計算部3、リプル変動計算部4および制御部5を備えている。検出部1は、蓄電装置10に関する蓄電装置パラメータである、蓄電装置10の温度、電圧値、SOC(State Of Charge:充電率)、蓄電装置10に入力される直流電流の電流値、蓄電装置10から出力される直流電流の電流値、蓄電装置10に印加されるリプル電流の周波数の少なくとも一つを検出する検出器である。インピーダンス計算部2は、検出部1の出力から蓄電装置10のインピーダンスを求める。リプル電流計算部3は、検出部1の出力から蓄電装置10に印加されるリプル電流の大きさを求める。リプル変動計算部4は、蓄電装置10のインピーダンスとリプル電流の値をもとに、蓄電装置10の電圧変動を推定する。制御部5は、リプル変動計算部4の出力である電圧変動の値があらかじめ定められた蓄電装置10の規定電圧範囲を超えないように変換器20を制御する。
図13は、実施の形態2による制御装置100aの構成を示す図である。実施の形態2による制御装置100aは、互いに並列に接続された複数のリアクトルと、複数のリアクトルのそれぞれに接続された複数の半導体スイッチング素子とを備えた変換器20aを制御するものである。図13に示す実施の形態2による制御装置100aを図1に示す実施の形態1による制御装置100と比較すると、リプル電流計算部3がリプル電流計算部3aになっており、制御部5が制御部5aになっており、リプル変動計算部4ではなく損失計算部6を備えている。損失計算部6は、変換器損失計算部61と電池損失計算部62とを備えている。実施の形態2による制御装置100aの他の構成は、実施の形態1による制御装置100の構成と同じである。
したがって、例示されていない無数の変形例が、本願に開示される技術の範囲内において想定される。例えば、少なくとも1つの構成要素を変形する場合、追加する場合または省略する場合、さらには、少なくとも1つの構成要素を抽出し、他の実施の形態の構成要素と組み合わせる場合が含まれるものとする。
