PROBLEM TO BE SOLVED: To provide a power supply circuit device which can make an abutment sound of a mechanical relay arranged in a bypass route hardly audible.SOLUTION: A battery unit U comprises switches 21, 23 which are arranged in electric routes L1, L3 to which the power of a lead acid battery 11 is supplied, and bring the electric routes L1, L3 into energization states or energization-blocked states, and bypass opening/closing circuits RE1, RE2 which are arranged in bypass passages B1, B2 bypassing the switches 21, 23, and bring bypass routes B1, B2 into energization states or non-energization states. The bypass opening/closing circuits RE1, RE2 are constituted of a plurality of bypass relays 31 to 34. In start processing, a control part 51 controls release or block timing of any of the bypass relays 31 to 34 out of the plurality of the bypass relays 31 to 34, and the release or block timing of the other bypass relays 31 to 34 by differentiating them.SELECTED DRAWING: Figure 1

    【課題】バイパス経路に設けられるメカニカルリレーの当接音を目立たなくすることができる電源回路装置を提供すること。【解決手段】電池ユニットUは、鉛蓄電池11の電力が供給される電気経路L1,L3に設けられ、電気経路L1,L3を通電又は通電遮断の状態とするスイッチ21,23と、スイッチ21,23を迂回するバイパス経路B1,B2に設けられ、バイパス経路B1,B2を通電又は通電遮断の状態とするバイパス開閉回路RE1,RE2を備える。バイパス開閉回路RE1,RE2を、複数のバイパスリレー31〜34により構成する。制御部51は、開始処理において、複数のバイパスリレー31〜34のうち、いずれかのバイパスリレー31〜34の開放又は閉鎖タイミングを、他のバイパスリレー31〜34の開放又は閉鎖タイミングと異ならせて制御する。【選択図】 図1
