PROBLEM TO BE SOLVED: To improve utilization efficiency of electric power generated by a solar cell.SOLUTION: A vehicular power supply control device is used for a vehicle comprising a power generator, a first battery connected to the power generator, a first control unit for controlling the power generator, and a load that can be connected to the first battery. The vehicular power supply control device comprises: a solar cell module; a second battery that is connected to the solar cell module and can be connected to the load; a first switch provided between the load and the first battery; a second switch provided between the load and the second battery; an electricity storage amount detection unit for detecting an electricity storage amount of the second battery; and a second control unit for controlling the first switch and the second switch. The second control unit switches open/closed states of the first switch and the second switch and switches a power supply source to the load on the basis of the electricity storage amount of the second battery detected by the electricity storage amount detection unit.SELECTED DRAWING: Figure 1

    【課題】 太陽電池により発電した電力の利用効率を改善することを目的とする。【解決手段】 本発明は、発電機と、発電機に接続された第1バッテリと、発電機を制御する第1制御部と、前記第1バッテリと接続可能な負荷とを備える車両に用いられる車両用電源制御装置であって、太陽電池モジュールと、太陽電池モジュールに接続されるとともに負荷に接続可能な第2バッテリと、負荷と第1バッテリとの間に設けられた第1スイッチと、負荷と第2バッテリとの間に設けられた第2スイッチと、第2バッテリの蓄電量を検出する蓄電量検出部と、第1スイッチおよび第2スイッチを制御する第2制御部と、を備え、第2制御部は、蓄電量検出部が検出した第2バッテリの蓄電量に基づいて、第1スイッチおよび第2スイッチの開閉状態を切り替えて、負荷への電力供給源を切り替える車両用電源制御装置とする。【選択図】 図1
