Integrated microbatteries are being currently developed to act as a "micropower" source in microsatellites. They help provide localized current capacities or embedded power supplies at the chip level, for space exploration. The microbatteries are charged using these complementary algorithms based on constant current, constant voltage and pulsed current. The charging current is in the range of nano-amperes. A unique experimental setup is developed to implement the nano charging algorithms. This designed setup is completely automated for maximum efficiency. Laboratory results are shown as part of this paper to prove the validity of the designed work. The microbatteries used are rated at 50nAH capacity and are solid state lithium electrolyte based.
