摘要：This paper deal with a power management .It consists of super capacitor cells and a lithium battery asenergy storages. That used for a photovoltaic (PV)-based wireless sensor network. The super capacitor has advantageof longer life time and large range of operating temperatures. The lithium battery has higher energy density. It requiresan accurate charge profile in order to increase its lifetime. Lithium battery has higher energy density. The featurecannot be easily obtained supplying the wireless node with a fluctuating source as the PV one. The best result in termsof energy density is obtained by combining the two storages. A statistic analysis is used in this proposed system thatused for sizing the storages and experimental results with 5W PV energy source.
