In the design of the photoelectric micro-power supply integrated with wireless sensor nodes,the hybridenergy storage technology was adopted to simplify the system design and to improve the performance of the energyconversion and storage for photoelectric micro-power supply which consists of the lithium ion battery and the supercapacitor. This paper introduced the principle of solar energy conversion and storage in the hybrid energy storagetechnology,and analyzed the load characteristics of hybrid energy storage technology. In addition,the characteris-tics of the hybrid energy storage were studied by experiment,which showed that the storage energy of photovoltaiccell output power was increased by roughly 27% by using hybrid energy storage method instead of useing the directenergy storage method,and the load characteristics of the photovoltaic micro-power supply was also improved. Theexperimental results were consistent with the theory analysis conclusion.
