To provide a power source control device capable of suppressing voltage drop of supply electric power to an electric apparatus that is generated in returning from idling stop by using a simple configuration with reduced cost.SOLUTION: A power source control device 1 includes: a current supply switching section 70 for switching between a current limited state where a current to be supplied from a storage battery 50 to an electric apparatus 71 is limited to a predetermined upper limit current or lower and a current non-limited state where the supply of the current exceeding the upper limit current from the storage battery 50 to the electric apparatus 71 is allowed; and a current supply control section 26 that executes current limiting processing for switching to the current limited state by using the current supply switching section 70 before an engine 60 stopped by using an idling stop function is started.SELECTED DRAWING: Figure 1
【課題】アイドリングストップからの復帰時に生じる電装機器への供給電力の電圧低下を、簡易でコストを抑えた構成により抑制することができる電源制御装置を提供する。【解決手段】電源制御装置1は、蓄電池50から電装機器71に供給される電流が所定の上限電流以下に制限された電流制限状態と、蓄電池50から電装機器71への上限電流を超える電流の供給が許容された電流非制限状態と、を切り替える電流供給切替部70と、アイドリングストップ機能により停止したエンジン60を始動させる前に、電流供給切替部70により電流制限状態とする電流制限処理を実行する電流供給制御部26と、を備える。【選択図】図1
