WIPO Patent Application WO/2023/139812
Kind Code:
A1
Abstract:
This power supply device comprises: an electricity storage unit including a first electricity storage device and a second electricity storage device; and a first switch used for switching a power supply source to a first electrical device between the first electricity storage device and the second electricity storage device in order that the first electrical device performs driving at least for a first period of time when a first condition is met. The first electricity storage device can supply power to a load and the first electrical device. The second electricity storage device can supply power to the load and the first electrical device. In a first use mode in which the power supply source to the first electrical device is set to the first electricity storage device, the power supply from the first electricity storage device to the load and the first electrical device and the power supply from the second electricity storage device to the first electrical device are limited until the first condition is met. In the first use mode, when the first condition is met, the power supply from the first electricity storage device to the load is limited, the power supply from the second electricity storage device to the first electrical device is limited, and the power supply from the first electricity storage device to the first electrical device is performed.
