This article proposes the innovative design of power system on robot, this system combines the lithium battery with ultracapacitor, causes lower battery impact due to the robot load, increases the lithium battery service life and the robot endurance of effectively. To design the dual power system of the ultracapacitor and the lithium battery, the analysis of the complementary characteristics between the ultracapacitor and lithium battery is introduced, and then to analysis the objective function and weight between the power and efficiency. The active status of operating power is decided by the lithium battery electric quantity and the ultracapacitor cumulative energy and the load necessities. The dc to dc converter is introduced to regulate the necessity of load voltage and power. The simulation of this dual power system reveals to achieve the
very good effect under pulse load on robot, the ultracapacitor absorption massive surging power to lighten burden of the lithium battery, this dual system may expand to the mobilized machines such as electric vehicle of the widespread applications.
