Description
次に、エネルギーECU400の機能の詳細について説明する。図2は、実施形態のエネルギーECU400の構成の一例を示す図である。エネルギーECU400は、例えば、状態取得部420と、供給制御部440と、切替制御部460と、電力制御部480とを備える。状態取得部420、供給制御部440、切替制御部460、および電力制御部480のそれぞれは、例えば、CPU(Central Processing Unit)などのハードウェアプロセッサがプログラム(ソフトウェア)を実行することにより実現される。また、これらの構成要素のうち一部または全部は、LSI(Large Scale Integration)やASIC(Application Specific Integrated Circuit)、FPGA(Field-Programmable Gate Array)、GPU(Graphics Processing Unit)などのハードウェア(回路部;circuitryを含む)によって実現されてもよいし、ソフトウェアとハードウェアの協働によって実現されてもよい。
次に、DC-DCコンバータ300における切替制御の内容について具体的に説明する。図3は、実施形態のDC-DCコンバータ300の構成の一例を示す図である。DC-DCコンバータ300は、例えば、変換部320と、切替部340とを備える。
図4は、実施形態の電力供給システム1により実行される処理の流れの一例を示すフローチャートである。図4の例において、状態取得部420は、補機500からの電力要求を受け付けたか否かを判定する(ステップS100)。補機500からの電力要求を受け付けたと判定した場合、状態取得部420は、燃料電池およびバッテリ200の状態を取得する(ステップS102)。次に、供給制御部440は、状態取得部420により取得された状態等に基づいて燃料電池100またはバッテリ200のうち、電力を補機500に供給する一方を選択する(ステップS104)。次に、切替制御部460は、選択された一方からの電力が補機500に供給されるようにDC-DCコンバータ300を制御して、それぞれの端子(第1端子360-1、第2端子360-2、第3端子360-3)間の導通状態と開放状態とを切り替えさせる(ステップS106)。電力制御部480は、補機500からの電力要求に基づいてDC-DCコンバータ300に電力を変換させ(ステップS108)、変換された電力を補機に供給させる(ステップS100)。
