Title:
ULTRAMICRO ENERGY CONVERSION CIRCUIT AND ENERGY STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/000870
Kind Code:
A1
Abstract:
The present application relates to an ultramicro energy conversion circuit and an energy storage device. The ultramicro energy conversion circuit comprises: a control module, a switch module, and a plurality of energy storage units, wherein the switch module is respectively connected to the control module, an ultramicro energy source, and the plurality of energy storage units; the control module is used for controlling the switch module to be in a first switch-on state, so that the plurality of energy storage units are connected in parallel to collect and store a charging voltage provided by the ultramicro energy source, and is also used for controlling the switch module to be in a second switch-on state, so that the plurality of energy storage units are connected in series to provide a discharge voltage for a load, the discharge voltage being greater than the charging voltage. Switching of the switch-on states of the switch module is controlled by the control module, and the low-voltage ultramicro energy appearing frequently is stored and applied in high voltage mode, thereby greatly improving the energy collection efficiency and expanding the application scene.
