Description
上記の電源装置によれば、二次電池およびキャパシタの充放電可能電力の低下が抑えられるため、これらの併用による負荷の駆動応答性を保つことができる。
図1は、この発明の実施の形態1による電源装置が適用されるモータ駆動装置の概略ブロック図である。
図2を参照して、冷却装置40は、蓄電装置C1側に設置された冷却ファンF10と、バッテリB側に設置された排気口44と、冷却ファンF10から取り込まれた冷却風を通流させるための冷却風流路とを備える。
図4は、この発明の実施の形態1の変更例による冷却装置の全体構成図である。なお、図4の冷却装置40Aは、図2の冷却装置40に対して、蓄電装置C1の筐体50とバッテリBの筐体52とが接触する部分の構造を変更したものである。よって、図2と重複する部分についての詳細な説明は繰り返さない。
先の実施の形態1で説明したように、低温の蓄電装置C1の上方に高温のバッテリBを積層して配置し、かつ、低温の蓄電装置C1から高温のバッテリBに向かって冷却風が通流するように冷却風流路を形成することにより、共通の冷却風を用いて蓄電装置C1およびバッテリBの双方を効率良く冷却することができる。
図6を参照して、冷却装置40Bは、図2の冷却装置40に対して、バッテリBと蓄電装置C1との配置における上下の位置関係を変更したものである。すなわち、バッテリBの筐体52の上方に蓄電装置C1の筐体50が積層されるように配置される。
さらに、冷却装置40Bによれば、蓄電装置C1およびバッテリBを筐体52の上方に筐体50が積層されるように配置したことにより、蓄電装置C1をより効率良く昇温することができる。
図7は、この発明の実施の形態3における冷却装置の概略構成図である。
冷却ファンF1,F2の駆動制御は、制御装置30によって行なわれる。制御装置30は、温度センサ20からバッテリ温度Tbを受け、温度センサ21からキャパシタ温度Tcを受け、温度センサ22から電源装置周辺の雰囲気温度Tiを受ける。そして、制御装置30は、これらの温度情報に基づいて、駆動させる冷却ファンを選択する。
制御装置30は、雰囲気温度Tiが所定の閾値T_stdよりも高いと判定されると、続いて、バッテリ温度Tbがキャパシタ温度Tcよりも高いか否かを判定する。
制御装置30は、雰囲気温度Tiが所定の閾値T_std以下と判定されたときには、続いて、バッテリ温度Tbがキャパシタ温度Tcよりも高いか否かを判定する。
