英文摘要：

With the development of supercapacitors, lithium batteries and other energy storage systems, the hybrid RTG energy saving technology becomes possible. The power demand of conventional RTG system was analyzed. The hybrid RTG schemes using super capacitor and lithium battery as auxiliary power source and high power lithium battery as the main source were compared from technical principle, dynamic parameters and system efficiency. It shows that the large capacity lithium battery was used as power supply of RTG to feedback the potential energy of fully recycling; the low power diesel engine as lithium battery charging power supply doesn＇t need to work continuously, making the system have the best comprehensive performance and certain novelty and good prospects.
