Abstract:
    The photo-volt battery (PV) and the lithium ion battery (LI) connect together via the charging protection circuit. The temperature difference battery (TD) and the super capacitor (SC) connect together via the DC/DC voltage raising circuit. The output ends of PV, LI and SC connect to the corresponding input ends of the energy source management circuit (ESM). The wireless transducer net node (WTNN) connects to the output end of ESM. PV and TD convert the environment light and heat into electrical energies to supply power to WTNN and charge simultaneously the twin energy-storage subsystem (TS). In case the power is not enough from the twin energy converter subsystem, TS supplies power to WTNN in stead. The invention extends the life of WTNN and solves the bottleneck problem of the energy source of WTNN.
