【Abstract】 The power management system for the integrated system of the photovoltaic-thermoelectric hybrid power source and the wireless sensor node was manufactured.The low power operation strategy,intelligentized control method and super -low lifting voltage technology were adopted in the power management,so the solar energy was utilized adequately. The charge curves of the supercapacitor and lithium-ion battery were obtained,and the efficiency of the power management was researched.The performance test of the power management system demonstrates that the lithium-ion battery could be charged within four days,and it could make the wireless sensor networks node work seven days continuously.更多还原
